9. Use substitution, 20 + 0.07(100) --) 20 + 7 --) $27; the answers D.

10. A is the answer for it the total number treats is divided by 10 and suppose to be equal to 60 bags.

11. 33.07 + 5.89 + 5(2.71) + 6.75 = amount you had in the beginning.

12. 4^2(5g + g) + 17 --) 16(5g + g) + 17 --) 80g + 16g + 17 --) 96g + 17; answer is c.

13.3^2(5x + 2x) - 24 --) 9(5x + 2x) - 24 --) 45x + 18x - 24 --) 63x - 24; answer is c.

14. 2x + 6x = 56 --) 8x = 56 --) x = 7; answer is c.

15. 20 + (1.5h - 1.5) = 32; the answer is a.

Hope this helps :)

3. Use the given information about the polynomial graph to write out the equation.

scZoUnD [109]

Answer:

$f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)$

Step-by-step explanation:

The standard form for a polynomial equation in its factored form is:

$f(x)=a(x-p)(x-q)...$

Where p and q are the zeros and a is the leading coefficient.

We know that the degree of the polynomial is 5.

We are also given roots at x=3 and x=-2. Hence, our factors are (x-3) and (x+2).

These have a multiplicity of two, so we will square them.

We also know that there is a root at x=4. Hence, the factor is (x-4). This has a multiplicity of 1.

Therefore, our polynomial is now:

$f(x)=a(x-3)^2(x+2)^2(x-4)$

We know that the y-intercept is 12. Therefore, if we substitute in 0 for x, we should get 12 for y. Here, we are solving for our a. Therefore:

$12=a(0-3)^2(0+2)^2(0-4)$

Evaluate:

$12=a(9)(4)(-4)$

Evaluate:

$-144a=12$

Divide both sides by -144:

$a=-1/12$

Hence, our entire polynomial is:

$f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)$

Larissa plans to bake at most 10 loaves of bread. She makes x loaves of banana bread that sell for $1.25 each and y loaves of nu

Veseljchak [2.6K]

Answer:

1) The system of inequalities are;

x × 1.25 + y × 1.5 ≥ 24

x + y ≤ 10

Please find attached the required graph of the two inequalities ,created with Microsoft Excel

2) The graph of inequality shows that Larissa cannot to make less than 10 loafs of bread and sell them for over $24 at the given prices of each loaf of bread

Step-by-step explanation:

1) The maximum number of loaves Larissa plans to make = 10

The price at which she sells each of x loaves of banana bread = $1.25

The price at which she sells each of y loaves of nut bread = $1.50

The total amount she hopes to make = $24

The system of inequalities are;

x × 1.25 + y × 1.5 ≥ 24

x + y ≤ 10

Making y the subject of both inequalities gives;

For the first inequality, we have,

y ≥ 24/1.5 - 1.25/1.5·x which gives;

y ≥ 16 - 5/6·x

For the second inequality, we have,

y ≤ 10 - x

Please find attached the required graph of the two inequalities

2) From the attached graph of inequality, created with Microsoft Excel, it shows that it is not possible for Larissa to make less than 10 loafs of bread and at the same time sell them for over $24 if the price of each banana bread is $1.25 and the price of each nut bread is $1.50.
