Which graph shows the solution to the system of linear equations?

y = 4x − 1
16x − 4y = 16

Answer:

4

Step-by-step explanation:

Keep subtracting the following number from the previous in the line to see the repetition for the interval pattern.

Answer: it should be 8.

Step-by-step explanation:

Step 1. Factor in the given variables.

(xy + 1) ÷ 7 becomes ((5)(11) + 1) ÷ 7

Step 2. Do the first part in parentheses

so (5) x (11) which is 55.

Step 3. Add together the full parentheses

so 55 + 1 which is 56

Final step, divide.

56 divided by 7 equals 8.

Answer:

12

Step-by-step explanation:

15 + (-3) = 12

you could also write it as 15 - 3 = 12

Answer: 12

Explanation:

15 is in +
-3 is in -

So, - and + = -

Write the Equation
15 - (-3)

(Do normal subtraction)
= 12 (which sign do we use?)

15 > -3

greater number sigh is + so,

+12 or 12 is the answer

Answer:

total angle of a triangle = 180°

other two angles = 85° , 65°

∴ the missing angle = 180 - ( 85 + 65 )

                                 = 180 - 150

                                 = 30

Answer:

D.

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

Because 3x 28.35 = 85.05 and then you multiply it by 1,000 which is 85,050.

whats the question?

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

Así que es esto, tienes que dividirlos, agregarlos y luego subratc, así que espero que esto ayude por un bye eek ooop 20 work limit

Hi

The aim of an equation is  to have  the letter on one side and a value to the pther side of the equal sign.  

For achieving this goal, I can use all operation I know and all quantities I want as long as I do it to each side in the same time. I will make apparent operation in bold.

So :  

2r - 5/4 = 58

if I want 2r  to be alone,  I need to get rid  of  -5/4  

The best way to do that is to add  5/4 to each side as  -5/4 + 5/4 = 0

so

2r -5/4 +5/4  = 58 +5/4

2r +0  = 58 +5/4

now we have :  

2r = 58+5/4

I will caculate the value of  58 +5/4

best way to do that is to convert 58 into  a  fraction .  as 58 *4 = 232  so  58 = 232/4

so now  we  have  :

2r = 232/4 +5/4

2r =  237/4

2r = 59.25

Now we have " 2r " , but my  aim is to have only one " r" .  So we  divide by "2" on each side :

2r /2  =  59.25 /2

r =29.625

If I want to check my result, I exchange the letter by the value I found.  

2 ( 29.625 )  - 5/4 =   59.25 - 5/4  =  59.25 - 1.25 =  58

as 58 is  the value given in line one for   2r - 5/4  , so my result is correct.

Answer:

r = 118.5

Explanation:

Given expression:

\(\sf \dfrac{2r-5}{4} = 58\)

Multiply Both sides by 4

\(\sf \dfrac{2r-5}{4} \times 4 = 58\times 4\)

Doing so gives:

\(\sf 2r-5 = 232\)

Add 5 on both sides

\(\sf 2r-5+5 = 232 + 5\)

Simplify following

\(\sf 2r = 237\)

Dividing Both sides by 2

\(\sf r = 118.5\)
