Answer:
x = 54
Step-by-step explanation:
These angles are complementary because they add up to 90:
x - 7 + 43 = 90
x + 36 = 90
x = 90 - 36
x = 54
Answer:
15
Step-by-step explanation:
7-(-1) is 8
8 divided by 4 (x or “run” of slope) is two
Two times five (y/rise of slope) is ten
5 (from original point -1,5) plus 10 is 15
(7,15)
this is as far as i could get. sorry

General Formulas and Concepts:
<u>Pre-Algebra</u>
Order of Operations: BPEMDAS
- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = -x² + 10x - 3
g(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: g(9) = -(9)² + 10(9) - 3
- Exponents: g(9) = -(81) + 10(9) - 3
- Multiply: g(9) = -81 + 90 - 3
- Add: g(9) = 9 - 3
- Subtract: g(9) = 6
Answer:
The y intercept is -2
Step-by-step explanation:
To find the y intercept, set x = 0 and solve for y
2x-5y=10
0 -5y = 10
Divide each side by -5
-5y/-5 = 10/-5
y = -2
