Answer:
x,y=(4, 15)
Step-by-step explanation:
We need to substitute the value of y=4x-1 and plug it into the equation 2x+y=23.
By this we get:
2x+4x-1=23
6x-1=23
6x=24
x=4
We can now solve for y using the given value of x.
2x+y=23
2×4+y=23
8+y=23
y=23-8
y=15
Hope this helps!

Put the following equation of a line into slope-intercept form, simplifying all fractions. 5x+6y=42
Answer:
\(y=-\frac{5}{6} + 7\)
Step-by-step explanation:
Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.
1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.
\(6y=-5x+42\)
2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:
\(y=-\frac{5}{6} + 7\)

Answer:
$8
Step-by-step explanation:
It says P = per ball (which will be a number, n, for balls times the fixed price) plus a set entrance fee. So we find that the price per ball is $0.80, so 10 balls cost $8.

Starting with the number 10, build a sequence of 5 numbers.
Answer:
Step-by-step explanation:
To build a sequence, you have to create a rule. For example, if the rule is +2, then you add 2 to 10 to get 12, and then you add 2 to 12 to get 14, and so on. Your sequence would then be 10, 12, 14, 16, 18.
On Monday the temperature was 32° On Tuesday the temperature was -5°. What was
the change in temperature?
Answer:
37°
Step-by-step explanation:
Think of 0° as a reference point. Then 32° is above this reference by 32 degrees, and -5° is below it by 5 degrees. Summing up 32 and 5, we get 37. The change in temperature was 37°
the graph of y = 4x^2 - 4x - 1 is shown use the graph to find estimates for the solutions of a and b
Answer:
a) -0.25 and 1.25
b) -0.5 and 1.5
Step-by-step explanation:
a) For 4x^2-4x -1 = 0
What we have to do here is to simply find he points on the x-axis in which the graph crosses it
we have this as;
approximately-0.5 and 1.5
what we are saying is that the plot crosses the x-axis at x = -0.25 and x = 1.25
ii) what we have to do here is to find the point at which y = 2
After finding this point, we trace it to the plot sideways, before we trace to the x-axis
By tracing, we have the crossing on the x-axis at these points at -0.5 and 1.5

In computing the "pth" percentile if the index "i" is an integer the "pth" percentile is the
a. data value in position "i"
b. data value in position "i" + 1
c. average of data values in position "i" and "i" + 1
The index "i" is an integer, then the "pth" percentile is simply the data value in position "i".
How the answer depends on the specific definition?The answer depends on the specific definition used for computing percentiles. However, the most common convention is to use linear interpolation, in which the "pth" percentile is the weighted average of the data values in positions "i" and "i+1", where "i" is the integer part of the index of the "pth" percentile, with weights given by the fractional part of the index. In other words, if "d(i)" and "d(i+1)" are the data values in positions "i" and "i+1", respectively, and "f" is the fractional part of the index, then the "pth" percentile is given by:
(1-f) * d(i) + f * d(i+1)
If the index "i" is an integer, then the "pth" percentile is simply the data value in position "i".

If Q has a y-coordinate of -4, what is the x-coordinate?
Answer:
x-coordinate is 3
Step-by-step explanation:
Q has y-coordinate of -4 => the distance from origin to y-coordinate is 4 units, which is one leg of the right triangle
Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
c^2 = a^2 + b^2
with c = 5, a = 4
5^2 = 4^2 + b^2
b^2 = 25 - 16 = 9
b = √9 = 3
so Q has coordinates (3,-4)
a sundae costs $2 additional toppings cost $.50 write and graph an equation in two variables that represent the total cost of a sundae
We can plοt these pοints (0, 2), (1, 2.5), (2, 3), and (3, 3.5) οn a cοοrdinate plane and draw a line cοnnecting them.
What is equatiοn ?An equatiοn is a mathematical statement that shοws that twο expressiοns are equal. It cοntains an equals sign (=) between twο expressiοns.
Fοr example, the equatiοn 2 + 3 = 5 shοws that the expressiοn 2 + 3 is equal tο the expressiοn 5. In this equatiοn, the expressiοns οn bοth sides οf the equals sign have the same value.
Let's define the twο variables:
Let x be the number οf additiοnal tοppings
Let y be the tοtal cοst οf the sundae, including the $2 base price and the cοst οf the additiοnal tοppings
Then we can write the equatiοn fοr the tοtal cοst οf the sundae as:
y = 2 + 0.5x
The $2 is the base price οf the sundae, and the $0.5x represents the cοst οf the additiοnal tοppings, where each tοpping cοsts $0.50.
Tο graph this equatiοn, we can plοt pοints οn a cοοrdinate plane. Let's chοοse a few values οf x and find the cοrrespοnding values οf y:
If x = 0 (nο additiοnal tοppings), then y = 2 + 0.5(0) = $2
If x = 1, then y = 2 + 0.5(1) = $2.50
If x = 2, then y = 2 + 0.5(2) = $3
If x = 3, then y = 2 + 0.5(3) = $3.50
Therefοre, We can plοt these pοints (0, 2), (1, 2.5), (2, 3), and (3, 3.5) οn a cοοrdinate plane and draw a line cοnnecting them. This line represents the tοtal cοst οf the sundae as a functiοn οf the number οf additiοnal tοppings.

Step-by-step explanation:
Sadie has $66,586 in a savings account. The interest rate is 11% per year and is not
compounded. How much will she have in total in 5 years?
Answer:
According to web results, the question can be solved using the simple interest formula, which is:
Simple Interest = Principal * Interest Rate * Time Period
Plugging in the given values, we get:
Simple Interest = 66,586 * 0.11 * 5
Simple Interest = 36,622.3
The total amount after 5 years is the sum of the principal and the simple interest, which is:
Total Amount = 66,586 + 36,622.3
Total Amount = 103,208.3
Therefore, Sadie will have $103,208.3 in total in 5 years.
Step-by-step explanation:
Answer:
Sadie will have $103,208.30 in her savings account in 5 years.
Step-by-step explanation:
Since the interest is not compounded, we can use the simple interest formula.
The formula for simple interest is
\(A=P\left(1+rt\right)\)
Where
\(A\) is the final amount
\(P\) is the initial amount
\(r\) is the interest rate as a decimal
\(t\) is the time in years
In this example we are given
\(P=66856\\r=0.11\\t=5\)
Knowing 3 of the 4 variables lets us evaluate the missing one.
Numerical Evaluation
Inserting these values into the simple interest equation yields
\(A=66586\left(1+0.11*5\right)\)
Lets evaluate \(A\).
Multiply \(0.11\) by \(5\).
\(A=66586\left(1+0.55\right)\)
Add \(1\) and \(0.55\).
\(A=66586\left(1.55\right)\)
Multiply \(66586\) by \(1.55\).
\(A=103208.3\)

when the spring is stretched and the distance from point a to point b is 5.3 feet, what is the value of θ to the nearest tenth of a degree?
a. 60.0
b. 35.2
c. 45.1
d. 55.5
When the spring is stretched and the distance from point a to point b is 5.3 feet, the value of θ is 53.13 degrees
The distance between point a to point b = 5.3 feet
The length of the top side = 3 feet
Therefore, it will form a right triangle
Here we have to use trigonometric function
Here adjacent side and the hypotenuse of the triangle is given
The trigonometric function that suitable for the given conditions is
cos θ = Adjacent side / Hypotenuse
Substitute the values in the equation
cos θ = 3 / 5
θ = cos^-1(3 / 5)
θ = cos^-1(0.6)
θ = 53.13 degrees
Therefore, the value of θ is 53.13 degrees

what is the difference between mtm and most?
Maximum Tolerable Moment, or MTM, is the greatest moment that a structure can withstand without breaking. Maximum Operating Stress, or MOST, is the highest amount of stress to which a structure can be subjected without experiencing permanent deformation.
Maximum Tolerable Moment, or MTM, is the greatest moment that a structure can withstand without breaking. Structural analysis techniques, such as finite element analysis and structural testing, are often used to determine this. When designing and building a structure, MTM must be considered because it is crucial for structural safety. Maximum Operating Stress, or MOST, is the highest stress to which a structure can be subjected without experiencing permanent deformation. This is often decided by running a stress study on the structure and taking into account the materials that were utilised to build it. The building must be able to sustain the anticipated loads throughout its lifespan, which is of utmost importance. Additionally, it is crucial to prevent structural deterioration over time. When designing and building a secure structure, MTM and Most must both be taken into account.
