X^2 + 2 = x + 8
x^2 - x + 2 - 8 = 0
x^2 - x - 6 = 0
Input 1 => 1^2 - 1 - 6 = 1 - 1 - 6 = -6
Input 3 => 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Input 4 => 4^2 - 4 - 6 = 16 - 4 - 6 = 6
Input 5 => 5^2 - 5 - 6 = 25 - 5 - 6 = 14
Solution set { -6, 0, 6, 14}
Answer:
Longest side = 13 inches
Step-by-step explanation:
Perimeter of triangle = 30 inches
x + 4x - 8 + 2x +3 = 30
x + 4x + 2x - 8 + 3 = 30
7x - 5 = 30
7x = 30 + 5
7x = 35
x = 35/7
x = 5
Longest side is the hypotenuse.
Longest side = 2x + 3 = 2*5 + 3 = 10 + 3 = 13 inches

c. Equally likely
d. Unlikely
e. Equally likely
f. Equally likely
g. Unlikely
h. Likely
i. No SPINNER SHOWN?
j. NO SPINNER SHOWN?
Step-by-step explanation:
The linear function: y = mx + b.
y(x - 1) = 9 → xy - y = 9 NOT (xy)
y - 5 = x(-x + 2) → y - 5 = -x² + 2x NOT (x²)
y(y - 1) = x + 25 → y² - y = x + 25 NOT (y²)
y - 5 = x - 20 → y = x - 15 YES
Answer:
|-4|+9
Step-by-step explanation:
|-4| is 4 and adding that to 9 equals 13
When it’s |-4+9|, it ends up being 5 because the absolute value of a positive number doesn’t change
