Trying this again for another 30 point and

Step-by-step explanation:

The red square means the two outside lines form a right angle which equals 90 degrees.

10x + 16 + 54 = 90

Simplify:

10x + 70 = 90

Subtract 70 from both sides

10x = 20

Divide both sides by 10:

X = 2

The answer is x = 2

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.
