Answer:

a) 72

b) $259.2

Step-by-step explanation:

A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.

360/40= 9

9*8= 72

B- $3.60 per gallon and 72 gallons in total.

3.60*72=259.2

$259.2

What is the solution for p in the equation?

Nookie1986 [14]

Answer:

p=-6

Step-by-step explanation:

the first thing to do is to add all like terms for example $\frac{1}{3}$ p+ $\frac{1}{2}$ p would turn into $\frac{2}{6}$ p+ $\frac{3}{6}$ p to make it so we can add them together which after we add both of those p's together we get $\frac{5}{6}$ p which now we have $\frac{5}{6}$ p+7= $\frac{7}{6}$ p+5+4 which now we add 5 and 4 which we get 9 which now the equation looks like $\frac{5}{6}$ p+7= $\frac{7}{6}$ p+9 which now we subtract 7 from 9 and we are left with 2 so now the equation is $\frac{5}{6}$ p= $\frac{7}{6}$ p+2 which now we subtract $\frac{7}{6}$ p from $\frac{5}{6}$ p and we are left with - $\frac{2}{6}$ p=2 which now we divide both sides by - $\frac{2}{6}$ which makes the equation look like p=2÷- $\frac{2}{6}$ which equals -6 so all we are left with is p=-6

Answer:

a) Translate the graph of f(x) down 3 units.

b) (8,-1) is a point on the graph of g(x)

Step-by-step explanation:

The transformations that subtract a constant number of units from the functional expression f(x) are transformations that lower the graph of the function in those many units,

Therefore they correspond to a translation of the original graph down the number of units involved.

In this case, the number of units involved is "3" (due to the "-3" added to the expression for f(x). So he correct answer for the first part is: Translate the graph of f(x) down 3 units.

For the second part, one has to try each of the coordinate pairs given in the new function g(x) to see which one results in a true statement:

1) Testing (-8,-1) by checking if replacing x with the value "-8" renders "-1" for the y-value: $g(x)=\sqrt[3]{x} -3\\g(-8)=\sqrt[3]{-8} -3\\g(-8)=-2-3\\g(-8)=-5$

so this is NOT a point on the graph of g(x).

2) Testing (-1,-2) by checking if replacing x with the value "-1" renders "-2" for the y-value: $g(x)=\sqrt[3]{x} -3\\g(-1)=\sqrt[3]{-1} -3\\g(-1)=-1-3\\g(-1)=-4$

so this is NOT a point on the graph of g(x).

3) Testing (2,-1) by checking if replacing x with the value "2" renders "-1" for the y-value: $g(x)=\sqrt[3]{x} -3\\g(2)=\sqrt[3]{2} -3\\$

the cubic root of 2 is not a rational number, because 2 is not a perfect cube, so the expression cannot be reduced, so this is NOT a point on the graph of g(x).

4) Testing (8,-1) by checking if replacing x with the value "8" renders "-1" for the y-value: $g(x)=\sqrt[3]{x} -3\\g(8)=\sqrt[3]{8} -3\\g(8)=2-3\\g(8)=-1$
