Answer:
x = 10; y = 20
Step-by-step explanation:
y = 2x
y = x +10
Substitute y of the second equation with 2x.
2x = x + 10
x = 10
y = 2x = 2(10)
y = 20
Answer: x = 10; y = 20

NEED HELP PLEASE ! WILL MARL BRANIEST IF RIGHT
Answer:
-9, -2, 14
Step-by-step explanation:
-1 is < 0 so plug it into the first function.
8(-1) -1 = -9
0 is ≥ 0 so plug it into the second function
8(0)-2 = -2
2 is ≥ 0 so plug it into the second function
8(2) - 2 = 14

(24.7C) The area of a rectangle is equal to x2 +
16x + 55 square units. If the length of the
rectangle is equal to x + 11 units, what expression
represents its width?
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5

A young person decides to put aside some money for retirement by putting $1,000 in a 30-year savings bond that pays 3.0% simple interest per year. The interest compounds. How much money will the person have after 30 years?
Answer:
2427.26 $
Step-by-step explanation:
Just use this formula when you have such type of problems:
N = N° (1 + %)^t
Where N = final amount
N°= initial amount
t = peroid of time
Now let's solve:
N = 1000(1 + 0.03)^30
N = 2427.26

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.

Nolan invested $5,300 in an account paying an interest rate of 3.8% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest tenth of a year, for the value of the account to reach $6,880?
HELP
Answer:
7
Step-by-step explanation:
did the question
The amount of money would be $6,880 in the account after 7 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Given data as follows:
p = $5,300
r = 3.8%
A = $6,880
A = P(1+r/100)ⁿ
Substitute the values of p,r, and A in the formula,
6,880 = 5,300(1 + 3.8/100)ⁿ
6,880/5,300 = (1 + 0.038)ⁿ
1.2981 = (1.038)ⁿ
n = 6.9954
Rounded to the nearest digit, and we get
n = 7
Therefore, the amount of money would be $6,880 in the account after 7 years.

Factor the follow expression:
8x−10
Select one:
2(x−5)
2(4x−5)
8(x−10)
2(4x−10)
Answer:
2(4x-5)
Step-by-step explanation:
find the greatest common factor (biggest number that goes into 8 and 10)
it is two
divide both by two
put 2 on the outside to symbolize that you multiply the inside by 2
2(4x-5)
Answer:
[tex]2(4x - 5)[/tex]
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
[tex]gcf = 2[/tex]
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]2( \frac{8x}{2} - \frac{10}{2} )[/tex]
3) Simplify each term in parentheses.

I need help please A. The relationship is linear because each Y-value is two more than the value before. B. The relationship is linear because each y-value is two times the value before it. C. The relationship is exponential because each y-value is two more than the value before it. D. The relationship is exponential because each y-value is two times the value before it.
Answer:
D) the relationship is exponential because each y-value is two times the value before
Step-by-step explanation:
A and B are out because this graph is not a linear graph. D is out because that explanation represents a linear graph. An exponential equation will always multiply the value before it, not add.
