Answer:
$10
Step-by-step explanation:
x is her weekly allowance.
She spent half her allowance and has ½x remaining.
She earned $7, and now has $12.
12 = ½x+7
x = 10
4.the dot would be on 1 1/2 and the x would be pointing toward the negative numbers
Considering the given graph of the function, we have that:
- Function Notation: f(1) = -3.
- Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.
<h3 /><h3>How to find the numeric value of a function looking at it's graph?</h3>
To find the numeric value of the function, we get a value of x(horizontal axis), and then look at the corresponding value y(vertical axis), then y = f(x).
In the graph of this function, we have that when x = 1, y = -3, hence:
- Function Notation: f(1) = -3.
- Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.

Answer:
0.36
Step-by-step explanation:
A= K/B^2
K= A × B^2
K= 1 × 3^2
K= 1×9
K= 9
Therefore if B is 5 then A can be calculated as follows.
K= A × B^2
9= A × 5^2
9= A × 25
9= 25A
A= 9/25
A= 0.36
Hence A is 0.36
