If x = 4, what is the value of 2x2 - 7?

Fudgin [204]

Answer:

A) 25

Step-by-step explanation:

I am assuming that you mean: 2x² - 7.

$2(4)^2 - 7\\\rule{150}{0.5}\\\rightarrow 2 *4^2 - 7\\\\\rightarrow 2 * 16 - 7\\\\\rightarrow 32 -7\\\\\rightarrow \boxed{25}$

Ratio problem, please give solution as well.

Allushta [10]

It's $21,000. You multiply $24,000 by 12.5% which is $3,000 then you minus that to 24,000.

3²+3[2³(√49 - 2²)(3² - 2³)-2²}

lukranit [14]

$3^2+3[2^3( \sqrt{49}-2^2)(3^2-2^3)-2^2]$

Right off the bat, this may look crazy, but if we take it step by step, it will be much easier. So, let's take it step by step. If any step doesn't make sense to you, you can always hmu.

$9+3[8( 7-4)(9-8)-4]$
$9+3[8( 3)(1)-4] = 9+3[24-4] = 9+3[20]$
$9+60 = 69$

Your answer is 69.

Answer:

(A) The rate of change in the price of a bushel of corn in the current year is $7.

(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Step-by-step explanation:

The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.

Part A:

The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.

The formula to compute the slope is:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Consider the ordered pairs: (4, 28) and (10, 70)

Compute the slope of the line as follows:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{70-28}{10-4}\\\\=\frac{42}{6}\\\\=7$

Thus, the rate of change in the price of a bushel of corn in the current year is $7.

Part B:

The data for the price of bushels in the previous year is as follows:

Number of Bushels Price

2 10

4 20

6 30

8 40

Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:

Consider the ordered pairs: (2, 10) and (6, 30)

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{30-10}{6-2}\\\\=\frac{20}{4}\\\\=5$

The rate of change in the price of a bushel of corn in the previous year is $5.

Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.
