enyata [817]

Answer:

$54.73 monthly installment for 6 months.

Step-by-step explanation:

Kevin just bought a refrigerator for $469.

He paid $140.6 in down payment and will pay the rest in equal installments.

If Kevin does not have to pay any interest and he will pay the rest amount in 6 months with monthly installments,

Then, the value of each installment will be = $\frac{469 - 140.60}{6} = 54.73$ Dollars. (Answer)

Which graph represents the function f(x)= 0.2^x + 3

Dennis_Churaev [7]

The third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation $f(x) = 0.2^{x} + 3$ , we substitute some values in the place of x.

When $x=0,$ $f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.$

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents $f(x) = 0.2^{x} + 3.$

When $x=1,$ $f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.$

The value of f(x) when $x=1$ is lesser than the value of f(x) when $x =0.$

So the third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

REY [17]

Answer:

The number of unsold cakes was 2

Step-by-step explanation:

The question in English is

In the school Francisco I. Madero of Ciudad Delicias, the celebration was held for commemorate the arrival of spring, after the parade the stalls were set up of the kermesse. The first grade group bought 8 cakes and sold 3/4 of the total.

How much of the cake was not sold?

Let

x ----> number of cakes sold

y ----> number of cakes that didn't sell

we know that

The first grade group bought 8 cakes

$x+y=8$ -----> equation A

The first grade group sold 3/4 of the total.

$x=\frac{3}{4}(x+y)$ ---> equation B

substitute equation A in equation B

$x=\frac{3}{4}(8)=6$

Find the value of y

$6+y=8$

$y=2$

therefore

The number of unsold cakes was 2

R = x(A + B) Solve for A.

larisa86 [58]

Answer:

A = $\frac{R}{x}$ - B

Step-by-step explanation:

Given

R = x(A + B) ← divide both sides by x

$\frac{R}{x}$ = A + B ( subtract B from both sides )

$\frac{R}{x}$ - B = A
