7. Which two equations are equivalent?

sineoko [7]

Answer:

C. $y=(x-3)^2$ and $y=x^2-6x+9$

Step-by-step explanation:

before answering the problem let us remind the formula for square of sum and differences

$(a+b)^2=a^2+2 \times a \times b + b^2$

$(a-b)^2=a^2-2 \times a \times b + b^2$

We are going to use the above two formulas to solve each part and come to an answer

A. $y = (x + 3)^2$

$(x + 3)^2=x^2+2 \times x \times 3 + 3^2$

$(x + 3)^2=x^2+6x+9$

Hence this option is not correct pair

B. $y = (x-5)^2$

$(x - 5)^2=x^2-2 \times x \times 5 + 5^2$

$(x -5)^2=x^2-10x+25$

Hence this option is also not correct pair

C. $y = (x -3)^2$

$(x - 3)^2=x^2-2 \times x \times 3 + 3^2$

$(x -3)^2=x^2-6x+9$

Hence this option is correct as it have equivalent pair

D. $y = (x + 5)^2$

$(x + 5)^2=x^2+2 \times x \times 5 + 5^2$

$(x + 5)^2=x^2+10x+25$

Hence this option is also not correct pair

What is the slope of A?

Aleonysh [2.5K]

Answer:

In the pic

Step-by-step explanation:

The dots that I used are from counting squares on A

* m = slope

* it's doesn't matter how you label each dot, you will get the same answer in the end.

JUST MAKE SURE THAT YOU DON'T MIX UP THE COORDINATES !!!

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below

Step-by-step explanation:

BOX 1) 5 plain pencils and 7 pens.

BOX 2) 6 color pencils and 2 crayons.

Plain pencil (first box) ~ 5 : 7

Color pencil (second box) ~ 6 : 2

Simplify.

3 : 1 <== Second box

Find the range of the function f(x)=x2+5 given the domain (-2,-1,0,1,2)?

iren2701 [21]

Answer:

(5, 6, 9)

Step-by-step explanation:

The domain is basically the set of all x values while the range is the set of all y values, in this case, it's the values of f(x). To find the range, we can plug the x values into the equation:

f(-2) = 9

f(-1) = 6

f(0) = 5

f(1) = 6

f(2) = 9

Since we can't have repeats in the range, it would be: (5, 6, 9)
