Answer:
Part a) 
Part b) The maximum number of candy bars that you can purchase is 4
Part c) The change would be 
Step-by-step explanation:
Part a) Write an equation representing your shopping experience and use x for the number of candy bars
Let
x -----> the number of candy bars
we know that
The inequality that represent this problem is equal to


Part b) Solve the equation to determine how many candy bars can you purchase?

Solve for x
Subtract 22.95 both sides


Divide by 0.43 both sides


The maximum number of candy bars that you can purchase is 4
Part c) How much change would you have left?
If you purchase 4 candy bars
then

therefore

Answer:
(2 , 0)
(1 , 0)
(4 , 0)
(0, -8)
Step-by-step explanation:
f(x) = x³ -7x² + 14x - 8
The y intercept occurs when x = 0.
This means the first three terms all go to zero an the result is y = -8
As we are given one factor, (x - 4), we know that one zero will occur when this factor is zero
x - 4 = 0
x = 4
taking out the x - 4 term from the quadratic
x³ -7x² + 14x - 8 = (x² ± Cx + 2)(x - 4)
we can see that
2x ± 4Cx = 14x
±4C = 12
C = 12/±4 = ±3
also
±Cx² - 4x² = -7x²
±C - 4 = -7
so C = -3
(x² - 3x + 2)
(x - 2)(x - 1)
x = 2
x = 1
Answer:
.125 is equal to 1/8 so do .125 times 7 and that equals .875
Step-by-step explanation:
.125=1/8
.125x7=.875
Answer:

Step-by-step explanation:
We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).
Recall that vertex form is given by:

Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.
Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:

It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:

Solve for <em>a: </em>

In conclusion, our quadratic function in vertex form is:
