Step-by-step explanation:

There are 3 critical points. Place them on the graph and go down (using a ruler and pencil).

-7, -5 trans forms into 7, -5

-4, -2 transforms into 4,-2

4, -4 transforms into -4, -4

Answer:

Graph C is the answer.

Step-by-step explanation:

Lola bought X pencils that cost $0.25 and Y erasers that cost $0.50.

Total expenditure is less than $3.

If we represent expense in the equation form then it will be

Expense on pencils + expense on erasers = Total expense which is < 3

0.25X + 0.50Y < 3

Now we divide the inequality by 0.25

X + 2Y < 12

This inequality when graphed, line will be plotted in dots and area below the line will be in the shaded form.

Slope of this line is = (-1/2) {from the standard equation of line y = mx + c)

Now we come to the graphs. Here dotted line graphs are A or C.

We will calculate the slopes of the lines from the graphs A and C to get tha answer.

For Graph A

The end points are (12, 0) and (0, 3)

So slope = (y-y')/(x-x') = (3-0)/(0-12) = -3/12 = -1/4

For Graph C.

End points the line are (0, 6) and (12, 0)

Slope of the line = (0-6)/(12-0) = -6/12 = -1/2

Therefore Graph C is the answer.

Answer:

36=x^2+5x

x^2+5x-36=0

(x+9)(x-4)

x= 4

x= -9

The Answer can be 4 or -9, see which option you have.

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

Usually what I do is sort of a guess and check, and this should be easy if your square roots memorized

First you know that x^2+5x is equaled to 36 because both sides of the triangle has a tick

I look at x squared first. You know the value for X has to be less than six because 6 squared is already 36.

Then I start plugging in values under 6 like 5, 4, 3 ex

When you plug in 5 you get 50, so we know we have to choose a lower value

When plugging in 4 you get 36

4 squared is 16, 5 x 4 = 20, 20+16 = 36

Answer:

y = \(\sqrt{55}\)

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(altitude)² = product of parts of hypotenuse

then

y² = 11 × 5 = 55 ( take square root of both sides )

y = \(\sqrt{55}\)

Answer:

18.2 cm

Step-by-step explanation:

Answer:

y=1/2+3

Step-by-step explanation:

For the first one, 0 and 3. 0/2 is not possible so we just add 3.

Second, 1/2 is 0.5 of 1/2. Plus 3 is 3 1/2.

Third, 2/2 = 1 + 3 = 4.

And last, 3/2 = 1.5 or 1 1/2. 1 1/2 + 3 is 4 1/2

Step-by-step explanation:

Answer: The team will need to run the route 0.15 miles / 2 miles = 7.5 times to cover a total distance of 2 miles.

Step-by-step explanation:

First, we need to convert the yard measurements to miles to make them consistent with the target distance of 2 miles. We can use the conversion factor 1 mile = 1760 yards.

48 yards = 48/1760 miles

80 yards = 80/1760 miles

46 yards = 46/1760 miles

92 yards = 92/1760 miles

Next, we can add up the distances on each side of the route to find the total distance covered by the track team.

Top: 48 yards + 80 yards = 128 yards = 128/1760 miles

Middle: 46 yards + 92 yards = 138 yards = 138/1760 miles

Finally, we can add up the top and middle distances to find the total distance covered by the track team.

128 yards + 138 yards = 266 yards = 266/1760 miles = 0.15 miles

So, the team will need to run the route 0.15 miles / 2 miles = 7.5 times to cover a total distance of 2 miles.

$575

Step-by-step explanation

1150/2 = 575

Answer:

$1150

Step-by-step explanation:

because it is a buy one (for sale price), get one free

Given that cos (0) = 0, we can use the Pythagorean identity sin^2(x) + cos^2(x) = 1 to find the value of sin (0).

sin^2(0) + cos^2(0) = 1

sin^2(0) = 1 - cos^2(0)

sin^2(0) = 1 - 0^2

sin^2(0) = 1

So, sin (0) = sqrt(sin^2(0)) = sqrt (1) = 1.

However, the given value is sin (0) = v3/6. This means that sin (0) = sqrt (3)/2, which is the value of sin (60). Therefore, the correct value of sin (0) is sqrt (3)/2, not 1.

Answer:

The correct option is (D) one of the non-fiction books on the bottom shelf and a second non-fiction book from the bottom shelf.

Step-by-step explanation:

What is probability?

Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true.

To find which 2 books describe a pair of dependent events:

A pair of two dependent events are simply those in which the selection of the second item is contingent on the selection of the first item, causing the probability to change.

Because the sample size is lowered when the initial item is taken without replacement, choosing the exact same item reduces the chance.

Now, in regard to the question, this means that for two of the occurrences to be independent, they must be on the same shelf and of the same type of book, so that the second book cannot be selected until the first one is.

Option D, where both books are on the same shelf and are of the same type, is the only option that fulfills this requirement.

Therefore, the correct option is (D) one of the non-fiction books on the bottom shelf and a second non-fiction book from the bottom shelf.

The dataset represented by the given box plot is 12, 15, 15, 17, 19, 19, 20, 22, 24 option B.

A box plot, sometimes called a box whisker plot, shows the distribution of a dataset graphically. The minimum value, the first quartile (25th percentile), the median (50th percentile), the third quartile (75th percentile), and the maximum value are the five main values used to standardise this method of displaying the distribution of data.

Two whiskers that extend from a rectangular box make up a box plot. The range of values between the first and third quartiles is represented by the box, which is known as the interquartile range (IQR).

From the given box plot we observe that the minimum value is 12 and the maximum value is 24.

Here, the median is 19.

For instance, if we have a vector v = (x, y, z), then multiplying it by a scalar factor k will result in a new vector kv = (kx, ky, kz), which is stretched or shrunk according to the value of k. Similarly, if we have a matrix A, multiplying it by a scalar factor k will result in a new matrix kA, where each element of A is multiplied by k.

The two correct options for time and work problem are: (a) and (d)

(a) The restaurant can make 24 pizzas in 5 hours

(d) The restaurant can make 48 pizzas in 10 hours

Time and work are fundamental to how work is done at the moment. The time and work problem gives us the exact relationship between workers and the number of days and hours it takes to complete a task. 

Solution according to the question:

Given, the restaurant can make 12 pizzas in 2.5 hours

So, when we double the time of work, the number of pizzas will also be doubled, i.e

24(12×2) pizzas in 5(2.5 ×2), hence option (a) correct.

Also, 10 hours is four times of 2.5 hours.

Thus, in 10 hours the restaurant will make 48 pizzas, so option (d) is the other correct option.

The ordered pair (-4 1/2, -1) can be represented by point P, which is located on a two-dimensional Cartesian coordinate system.

The Cartesian coordinate system is a system of two-dimensional coordinates used to identify the position of a point, line, or shape. It is based on a two-dimensional grid that is composed of two perpendicular lines, called the x-axis and the y-axis. The origin (0,0) is the point where the two axes intersect.

The ordered pair contains two numbers, which are the x-coordinate and the y-coordinate respectively. The x-coordinate of the point P is -4 1/2 and the y-coordinate is -1. This means the point P is located 4 1/2 units to the left of the y-axis and 1 unit below the x-axis.
