What are the solutions to the equation x² = 625?
choose all answers that are correct.
a.
–312.5
b.
–25
c.
25
d.
312.5

B - 25

C. 25

Step-by-step explanation:

What are the solutions to the equation x² = 625?

The expression is

x² = 625

The expression want us to find the value of x.

x² = 625

since x is in square, to cancel the square on x we square root both sides.

Square rooting both sides

√x² = √625

x = √625

x = 25

The value of x is 25

The answer can also be -25 , since the square of -25 is also equals to 625.

-25 × -25 = 625

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer to this question is 3/19
