Answer:
A
Step-by-step explanation:
Given
x² = 27 ( take the square root of both sides )
x = ± 
= ± 
= ± 
× 
= ± 3 → A
Answer:
a = 15
Step-by-step explanation:
The graph of function g(x) is described by g(x)=ax−7, or y = ax−7.
y = g(x)=ax−7 passes through (1/3, -2). We can subst. -2 for y and 1/3 for x to determine the value of the coefficient a:
-2 = g(1/3) = a(1/3) - 7
Solve for a. First, add 7 to both sides: 5 = a(1/3).
Next, multiply both sides by 3: 15 = a, or a = 15.
Answer:
The mean number of cookies was 33.5
Step-by-step explanation:
Add the values of the terms and divide by the number of terms.
So...
26 + 38 + 45 + 25 = 134
134 ÷ 4 = 33.5
