Step-by-step explanation:

To find the first table y = 4x + 2, to find each y value we have to substitute each x value into the equation.

4(-2) + 2 = -6 so -2 is going to have the y as -6

4(-1) + 2 = -2 so -1 is going to have the y as -2

4(0) + 2 = 2 so 0 is going to have the y as 2

4(1) + 2 = 6 so 1 is going to have the y as 6

4(2) + 2 = 10 so 2 is going to have the y as 10

So these are the points you would graph (-2, -6), (-1, -2), (0, 2), (1,6), and (2, 10)

For the next talbe y = 3x + 1 we do the same thing

3(-2) + 1 = -5 so -2 is going to have the y as -5

3(-1) + 1 = -2 so -1 is going to have the y as -2

3(0) + 1 = 1 so 0 is going to have the y as 1

3(1) + 1 = 4 so 1 is going to have the y as 4

3(2) + 1 = 7 so 2 is going to have the y as 7

The ooints to graph are (-2, -5), (-1, -2),(0,1), (1, 4) and (2,7)

For the next table y = 6x - 5

6(-2) - 5 = -17 so -2 is going to have the y as -17

6(-1) - 5 = -11 so -1 is going to have the y as -11

6(0) - 5 = -5 so 0 is going to have the y as -5

6(1) - 5 = 1 so 1 is going to have the y as 1

6(2) - 5 = 7 so 2 is going to have the y as 7

The points to graph (-2, -17), (-1, -11), (0, -5), (1, 1) and (2, 7)

For the next table y = 5 + 2x

5 + 2(-4) = -3 so -4 is going to have the y as -3

5 + 2(-2) = 1 so -2 is going to have the y as 1

5 + 2(0) = 5 so 0 is going to have the y as 5

5 + 2(3) = 11 so 3 is going to have the y as 11

5 + 2(5) = 15 so 5 is going to have the y as 15

(-4, -3), (-2, 1), (0, 5), (3, 11) and (5, 15)

For the next table y = 8x - 10

8(-4) - 10 = -42 so -4 is going to have the y as -42

8(-2) - 10 = -26 so -2 is going to have the y as -26

8(0) - 10 = -10 so 0 is going to have the y as -10

8(2) - 10 = 6 so 2 is going to have the y as 6

8(4) - 10 = 22 so 4 is going to have the y as 22

(-4, -42), (-2, -26), (0, -10), (2, 6) and (4, 22)

For the last table

2(-2) = -4 so -2 is going to have the y as -4

2(-1) = -2 so -1 is going to have the y as -2

2(0) = 0 so 0 is going to have the y as 0

2(-1) = -2 so -1 is going to have the y as -2

2(-2) = -4 so -2 is going to have the y as -4

(-2, -4), (-1, -2), (0, 0), (-1, -2) and (-2, -4)

Answer:

The watermelon candies taste $0.13 more.

Step-by-step explanation:

First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.

-3(x + 5) = 6 - 3(2x + 4) solve for x and show work

Answers

Your answer is x = 3.

-3(x + 5) = 6 - 3(2x + 4)
-3x - 15 = 6 -6x - 12
-3x - 15 = -6 - 6x
-3x + 6x = -6 + 15
3x = -6 + 15
3x = 9
x = 3

Answer:

Step-by-step explanation:

-3(x + 5) = 6 - 3(2x + 4)

-3x - 15 = 3(2x + 4)

Determine the x- and y-intercepts of the graph of x+2y=−4 . Then plot the intercepts to graph the equation.

Answers

Answer:

To determine the y-intercept, convert the equation into slope-intercept form.

x + 2y = -4

Subtract x from both sides

2y = -x-4

divide by 2 on both sides

y = -1/2(x) - 2 (this is the formula, with a slope of -1/2 and y-intercept of -2

This gives you a y-intercept of -2, which can be plotted at (0, -2)

For the x-intercept, plug in 0 for y into the formula.

x + 2y = -4

x + 2(0) = -4

x + 0 = -4

x=-4

This gives you an x-intercept of -4, which can be plotted at (-4, 0). Put those two numbers on the line and graph it, remembering that your slope is -1/2

How can you solve standard form and intercept form?

Answers

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

Please help im just a middle schoolor!!!!! The distance between City A and City B is 250 miles. A length of 1.7 feet represents this distance on a certain wall map. City C and City D are 3.74 feet apart on this map. What is the actual distance between City C and City​ D?

Answer:

Distance between City C and City D is 550 miles

Step-by-step explanation:

Given that:

City A and City B are 250 miles apart with a length of 1.7 feet;  &

City C and City D are x miles apart with a length of 3.74 feet.

To find the distance ( in x miles) between City C and City D, we use the ratio or proportionality concept.

i.e

250 miles = 1.70 ft

x miles =  3.74 ft

By cross multiplying, we get:

(250 * 3.74) = ( x * 1.70)

x = (250 * 3.74)/ 1.70

x = 550 miles.

Thus, the distance between City C and City D is 550 miles

What is the solution to the equation 3/5(y-5) = - (y+3) +2

Answers

Answer:

[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Given expression:

           [tex]\frac{3}{5}[/tex](y - 5)   =  - (y + 3) + 2

    To solve this problem, multiply both sides by 5;

  5 x   [tex]\frac{3}{5}[/tex](y - 5)   = 5[-(y + 3) + 2}

         3(y - 5) = 5(-y - 3 + 2)

         expand,

          3y - 15  = 5(-y -1)

          3y -15  = -5y - 5

    Collect like terms;

          3y + 5y  = -5 + 15

             8y  = 10

               y  = [tex]\frac{10}{8}[/tex]  = [tex]\frac{5}{4}[/tex]
