Y=-3x+2:
Already in slope intercept form
Graph by plotting a point on (0,2)
Then move 3 points up and 1 to the right and plot the point and keep doing that a couple times

-3x-y=-2:
Add -3x on both sides
The result would be
-y=3x-2
Divide everything by negative 1
Y=-3x+2

Both equations are the same so they are the same line

Those are the same graph. just written in different ways the first one u listed is in slope intercept already. the second one, just rearrange using proper algebra and they become the same. the slope is -3 and the y intercept is at (0,-2). this means starting at (0,-2) thenext point willbe 1 over to he right, 3 down. before (0,-2), though, will be 1 over o the left and 3 up

Answer:

see explanation

Step-by-step explanation:

let n and n + 2 be 2 consecutive even numbers , then

(n + 2)² - n² ← is the difference

= n² + 4n + 4 - n²

= 4n + 4

= 4(n + 1) ← a multiple of 4

For his birthday, Mr. Robin and four of his friends went to a Math museum to learn about new intergalactic math. They each got a
Helen [10]

Answer: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for \$12 each

If each one of them bought a calculator then the total spendings are \$110

Suppose the cost of each calculator is \$\ x

Cost per person is given by  x+\$12

For the group, it is 5(x+12)

Equate this to total spendings

\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10

thus, the cost of each calculator is \$ 10

A certain fish grows so that after t years of life its length is given by L(t) = 9 − 1/5t inches. Calculate the average rate of
vfiekz [6]

Answer:

Step-by-step explanation:

Given the length of a fish after t years modeled by the equation

L(t) = 9 − 1/5t

The average rate of growth is expressed as;

dL/dt = -1/5 (differential of a constant is zero)

Hence the average rate of growth  over the first year of life is -1/5 in/year

Blank _/32 = 7/8 fractions
Anni [7]

Answer:

28

Step-by-step explanation:

To begin, lets make an equation out of this problem,

x/32 = 7/8

Then, let's solve for the variable x or AKA the missing value

x/32 x 32 = 7/8 x 32

x               = 28

So, there is the answer, the missing value is 28
