The constant term should be (-5/2)^2 or (5/2)^2 or 25/4. This constant term comes from taking the coefficient on the x^1 term, halving it, and then squaring it.
If x = 7 you substitute all the x in the equation by 7:
y = -2(7) + 5
y = -14 + 5
y = -9

Happy homework/ study/ exam!
The greatest common factor of 8x and 22yx is 2x.
I got this answer by factoring out 8 and 22:
8: 1,2,4,8
22: 1,2,11,22
Their greatest common factor was 2 and they both have x.
Your answer is 2x.
Hope this helped! :)
Answer: z = 
Step-by-step explanation:
To find <em>z</em>, you must set up a proportion to solve.
To find the altitude of a special right triangle, the formula is:

You can use <em>5</em> as <em>a</em> and <em>2</em> as <em>b</em> to complete the proportion:

Next, to solve:
<u>Step 1</u>: Cross-multiply.

(5)*(2) = z*z
10 = z²
<u>Step 2</u>: Take square root.
10 = z²
√10 = z
