Answer:
$17.45
Step-by-step explanation:
$17.45*3=52.35
$52.35+$45.99=$98.34
The value of f(0) is -1
<h3>What is a function?</h3>
A function can be defined as an expression, law or rule that explains the relationship between two variables; a dependent and an independent variable.
Given the function;
f(x)= -x - 1
To determine f(0), we substitute the value of x as 0 in the function
So, we have;
f(0) = -(0) - 1
f(0) = -0 - 1
f(0) = -1
Thus, the value of f(0) is -1

If you would like to know if (0, 3) is a solution to the equation y = x + 3, you can find this using the following step:
(0, 3) = (x, y)
x = 0
y = 3
y = x + 3
3 = 0 + 3
3 = 3
Result: (0, 3) is a solution to the equation y = x + 3.
Answer:
4
Step-by-step explanation:
if you put it in y=mx+b form you would get y=4x-8=72
Answer:
Y=×^2-9
Step-by-step explanation:
(X+0)^2-9
Use the vertex form, y=a(x-h)^2+k
a=1
h=0
k=-9
And because the parabola opens up the vertex is (0,-9)
The distance from the vertex to a focus of the parabola by using the __ 1/4a__ formula:
1/4(1)
1/4
(h,k+p)
(0,-35/4)
