Answer:

First of all this question makes no complate sense if this was in real life. But the answer is: Allen is 23 years old and Jim woukd be 12 1/2 years old.

Step-by-step explanation:

Because 20+3=23. That's because it said in 3 years. Tthen we divide by 2 to find Jim's age. That's because it said that in three years, Allen would be twice as old as Jim.

Answer:

No solution

Step-by-step explanation:

The requirements set by this problem aren't possible to meet simultaneously. You can do your algebra for each one and find an answer. In this case, I found that the age of Jim was 23, and Allen 43, but those ages do not match the criteria of Allen being 2 times as old as Jim. Your teacher gave you a problem without remembering that both of the people in the problem are aging at the same time. That's the only possible explanation I have for this problem.

astraxan [27]

Answer:

9/-24 or ~ -0.38

Step-by-step explanation:

x y

3 9

12 -15

from 9 to -15 it will be subtracting 24

From 3 to 12 it will be adding 9

y/x = 9/-24 or -0.375 ~ -0.38

Mark got a loan of $77000 which he will complete repayment in

Evgesh-ka [11]

Answer:

A = $94652.66

Step-by-step explanation:

Use the compound amount formula A = P(1 + r/n)^(nt), where r is the annual interest rate and n is the number of compounding periods per year.

Here, A = ($77000)(1 + 0.07/2)^(2*3), or

A = $77000(1.035)^6, or

A = $77000(1.229), or

A = $94652.66

What is the slope of the line?

Blizzard [7]

Answer:

Not enough information given

Step-by-step explanation:

To find the slope, you need two points. You put the values into this formula:

(y_2 - y_1) / (x_2 - x_1) = m

The underscores show which ordered pair, so _2 means the values from the second one.

m stands for slope.

X values:−10,−3-, 4, 11

Alex Ar [27]

Answer:

It is neither linear nor exponential.

Step-by-step explanation:

x values: −10,−3, 4, 11

y values: 1, 6, 30, 120

Slope = rate of change

$m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{6-1}{-3+10}\\m=\frac{5}{7}$

$\\m = \frac{y_3-y_2}{x_3-x_2}\\m = \frac{30-6}{4+3}\\m=\frac{24}{7}$

Since rate of change is not constant . So, It is not linear

If the average rate of change is constant, then the function is linear.

If the ratio of consecutive outputs is constant, then the function is exponential.

So, $\frac{y_2}{y_1}=\frac{6}{1}=5\\\frac{y_3}{y_2}=\frac{30}{6}=6\\\frac{y_4}{y_3}=\frac{120}{30}=4$

Since the ratio of consecutive outputs is not constant.

So, It is not exponential

Hence it is neither linear nor exponential.
