Slope = -5/4
y intercept = 1
The slope is always attached to x. The intercept is the number attached on the end.
To find the range of these scores, we must take the largest scores and subtract the smallest from it.
The largest score is 99, and the smallest score is 80.
99 - 80 = 19
Answer:
x
>
10
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
-9x(5 - 2x) Distribute/multiply 9x into (5 - 2x)
(-9x)5 - (-9x)2x
-45x - (-18x²) 2 negative signs cancel each other out and become +
-45x + 18x² Your answer is A ( the first option)
