Seventy five times an integer minus 36 equals the square of the integer? which equation could be used to solve for the unknown integer?

75x - 36 = x²

Step-by-step explanation:

let x be the integer

75x - 36 = x²

More or less, translate each section of the problem in word form into algebraic form.

"Seventy five times an integer" is 75x

"minus 36" is -36

"equals the square of the integer" is = x²

To solve:

Since 75x - 36 = x² is a quadratic, use the quadratic formula.

Rearrange so that all terms are on one side.

This is called standard form (ax² + bx + c = 0)

75x - 36 = x²

0 = x² - 75x + 36

a = 1   b= -75   c=36

 (ignore that weird A)

Substitute a, b and c into the quadratic formula to solve for x, the integer.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
