Write an equation in the form y=mx+b that represents the x-y table

Answers

Choose two coordinates. I will choose the ones you chose, (-2, -3) and (0, 1).

Find the slope first using the slope equation: [tex]\frac{y2-y1}{x2-x1}[/tex]

y2 is 1, y1 is -3, x2 is 0, and x1 is -2.

[tex]\frac{1-(-3)}{0-(-2)}[/tex]

[tex]\frac{1+3}{0+2}[/tex]

[tex]\frac{4}{2}[/tex]

m = [tex]2[/tex]

The slope is 2.

Now that we found out the slope, we can start to assemble our equation. The m in the equation y = mx + b stands for the slope.

Now the equation is: y = 2x + b.

We need to figure out the y-intercept next. The b in the equation stands for the y-intercept. Choose one coordinate. I will chose (0, 1). x = 0 and y = 1. Substitute 0 in for x and 1 into y.

y = 2x + b

1 = 2(0) + b

1 = 0 + b

1 = b

Now we know what b is. Plug in 1 for b in the equation.

y = 2x + 1

I hope this helps! Let me know if I got something wrong and I'll fix it.

Ivy and her brother, Hayden, each got a box of chocolates for Valentine’s Day. Her box contained 12 chocolates, and his box contained 10 chocolates. They both knew that their dad loved chocolate, so they each gave him half of their chocolates. Also, they each gave their mother two chocolates; then they ate the rest. How many chocolates did Ivy get to eat? How many chocolates did Hayden get to eat?

Answers

Answer: 10 and a half For ivy For Hayden 8 half

Step-by-step explanation: because ivy gave Her mother 2 each and her father half and for her brother

Answer:

Given to father by Ivy: 12/2=6

Given to father by Hayden: 10/2=5

Now,

Chocolates given to mother by Ivy: 2

Chocolates given to mother by Hayden: 2

Now total chocolates given by Ivy to mother and father: 6+2 = 8

Now total chocolates given by Hayden to mother and father: 5+2=7

Now total chocolates left  with Ivy 12-8=4

Now total chocolates left with Hayden: 10-7= 3

Thus ivy and Hayden has  4&3 chocolates respectively

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Your answer would be 189

Step-by-step explanation:

if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

Complete the process of solving the equation.
Fill in the missing term on each line. Simplify any fractions.
5t+8=13
5t=
Subtract 8 from both sides
t=
Divide both sides by 5

Answers

Answer:

t = 1

Step-by-step explanation:

5t + 8 = 13

Subtract 8 from both sides

5t + 8 - 8 = 13 - 8

5t = 5

Divide both sides by 5

5t/5 = 5/5

t = 1

Check:

5t + 8 = 13

5(1) + 8 = 13

5 + 8 = 13

Answers

Answer:

A.

Step-by-step explanation:

Hi there!

By factoring the trinomial, we end with (x-9)(x-4)

However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.

0 = x - 9

0 = x - 4

Using orders of operations, x = 9 and x = 4

Therefore,  A is your answer.
