What value do you square to get 9?

Dominik [7]

Answer:

3 or -3

Step-by-step explanation:

What number multiplied by itself will give you 9

1*1 =1

2*2 =4

3*3 =9

Also note that negative times negative will be positive so

-1*-1=1

That means -3*-3 = 9

A system of equations is given below:

My name is Ann [436]

Solving by substitution:

y = 4x - 3

2x + 7y = 41

Let us substitute the first equation y = 4x - 3 into the second.

2x + 7y = 41

2x + 7(y = 4x -3) = 41

2x + 7(4x -3) = 41

So that's the third option.

I hope this helps.

Explain why each table determine if y is proportional to x .

lesya692 [45]

Answer:

see explanation

Step-by-step explanation:

If y is proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k divide both sides by x

k = $\frac{y}{x}$

This value must be constant for all ordered pairs, thus

k = $\frac{4}{6}$ = $\frac{2}{3}$

k = $\frac{6}{9}$ = $\frac{2}{3}$

k = $\frac{8}{12}$ = $\frac{2}{3}$

k = $\frac{2}{3}$

Since k is constant for all ordered pairs then y is proportional to x
