Answer:
-12, -21
Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.

One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circle. What is the ratio of the area of the smaller circle to the larger circle?
A 2:3
B 1:6.4
C 1:16
D 1:64
Answer:
Step-by-step explanation:
d₁ = 6 inches
r₁ = 3 inches
area = πr₁² = 9π in²
d₂ = 24 inches
r₂ = 12 inches
area = πr₂² = 144π in²
ratio of areas = (9π)/(144π) = 9/144 = 1/16

11.Write the equations of linear and exponential functions that pass through the points (0,9) and (1,3)
9514 1404 393
Answer:
y = -6x +9
y = 9·(1/3)^x
Step-by-step explanation:
In each case, the y-intercept is 9.
Linear
The slope is rise/run = (3-9)/(1-0) = -6, so the equation is ...
y = mx + b . . . . . . . slope m, intercept b
y = -6x +9
Exponential
The ratio of value at x=1 to that at x=0 is 3/9 = 1/3. That is the "growth factor," so the equation is ...
y = 9·(1/3)^x
0.36x=-1.8

When three times a number is subtracted from 36, the result is 4 plus the number. What is the number?
Answer:
x = 8
The number is 8
Step-by-step explanation:
36 – (3x) = 4 + x
36 – (3 • 8) = 4 + 8
36 – 24 = 12
12 = 12
x = 8
I hope this helps.

Answer: The formula to determine the multiplier is M = 1 / (1 - MPC). Once the multiplier is determined, the multiplier effect, or amount of money needed to be injected into an economy, can also be determined. This amount is calculated by dividing the total amount of spending needed by the multiplier.
Step-by-step explanation:
Bashir deposits money into a savings account every year. In his first year of saving money, he deposited $1,500.
Each year after that, he deposited $2,250. Write an explicit expression to represent the total amount of money, in
dollars, Bashir has deposited into his account, where n represents the number of years he has been contributing
money to the account.
For n ≥ 1, the explicit expression is

Step-by-step explanation:
Answer:
aₙ = 2250n - 750Step-by-step explanation:
This is an arithmetic progression with:
The first term a₁ = 1500Common difference d = 2250Required expression is:
aₙ = a₁ + (n - 1)daₙ = 1500 + (n - 1)2250 = 1500 + 2250n - 2250 = 2250n - 750It is not possible to divide 5 by 0 because there is no number you can___ by 0 and get 5 .

A beverage distributor has a facility that bottles beer. Beer bottles are supposed to be filled to 12 oz but there are slight variations. As part of quality control, they randomly sample bottles of beer and measure how many ounces they contain. In the most recent sample, the found an average fill of 12.01 oz with a standard deviation of 0.89. Quantitative Question 2a If one of the bottles of sampled beer was filled to 10.98 oz, what is its associated zscore
Answer:
Its associated z-score is -1.16.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In the most recent sample, the found an average fill of 12.01 oz with a standard deviation of 0.89.
This means that [tex]\mu = 12.01, \sigma = 0.89[/tex].
If one of the bottles of sampled beer was filled to 10.98 oz, what is its associated zscore
This is Z when X = 10.98. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{10.98 - 12.01}{0.89}[/tex]
[tex]Z = -1.16[/tex]
Its associated z-score is -1.16.
What type of angles are these?
Complementary, Supplementary, or Neither
Got It? Do these problems to find out.
-15
85° | 90°
75
Answer:
a: Neither; b: Complementary
Step-by-step explanation:
Complementary= 90 degrees
Supplementary= 180 degrees
For letter a. the answer is neither because 85 +90= 175 degrees, not 90 or 180 degrees.
For letter b. the answer is complementary because 75 +15= 90 degrees.
What is the measure of the obtuse angle in this figure?
Its not 180
Answer:
C
Step-by-step explanation:
7x+5=180
7x= 175
x- 25
so 5(25)+4= 129
which is C

Answer:
20 + 35x
Step-by-step explanation:
We have the expression 5(4 + 7x) and are asked to distrbute it.
When distributing, it's very simple, all you have to do is multiply the number outside the parenthesis with the numbers inside the parenthesis.
Therefore :
(5(4) + 5(7x))
20 + 35x
