in the following year, the value of imports to Greece decreased by 25%. If the value of Italian imports decreased by $750 millio

DochEvi [55]

Assuming the decrease is uniformly distributed over all countries, then the following year's import from Italy is also 25%.

Next year's import
=750(1-25%)
=750(0.75)
=562.5 million (units).

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.

natulia [17]

$f(x)=4(x+3)-5 \\ f(x)=4x+12-5 \\ f(x)=4x+7 \\ \\
\hbox{solve for x:} \\
y=4x+7 \\
y-7=4x \\
x=\frac{y-7}{4} \\ \\
\hbox{swap x and y:} \\
y=\frac{x-7}{4} \\ \\
f^{-1}(x)=\frac{x-7}{4} \\
f^{-1}(3)=\frac{3-7}{4}=\frac{-4}{4}=-1 \\
\boxed{f^{-1}(3)=-1}$

Select the graph of the solution set that would represent the following expression. (x-2)=5(x+1)

Lesechka [4]

Answer:

Find the attached

Step-by-step explanation:

We have been given the following expression;

(x-2)=5(x+1)

We are required to determine the graph of the solution set. To do this we formulate the following set of equations;

y = x - 2

y = 5(x+1)

We then graph these two equations on the same cartesian plane. The solution will be the point where these two graphs intersect.

Find the attachment below;

One side of trapezoid is 10 inches. The side parrellel to this is twice as long as this side. The height is half as long as the

madam [21]

The first side is 10 inches
the side parallel to this is (10×2)= 20 inches
Height is half the length=1/2×20=10 inches
The area of trapezium is given by:
Area=1/2×h×(a+b)
where a and b are the sides, h is the height. Thus the area will be:
Area=1/2×10×(20+10)
=1/2×10×30
=150 sq. inches
