4x+12 is the right answer.Jeffrey is 5 years older than his brother. If j represents Jeffrey’s age, the expression j−5 can be used to find his brother’s age. If Jeffrey is 23, how old is his brother?
If j=23 and j-5 is how old Jeffery's brother is then Jeffrey's brother is 17 years old.
So j=17
Find each value given f(x).
1. If f(x) = 2x + 3, then f(5) =
Answer:
f ( 5 ) = 13
Step-by-step explanation:
Step 1:
f ( x ) = 2x + 3 Function
Step 2:
x = 5 Given
Step 3:
f ( 5 ) = 2 ( 5 ) + 3 Input x value
Step 4:
f ( 5 ) = 10 + 3 Multiply
Step 5:
f ( 5 ) = 13 Combine Like Terms
Answer:
f ( 5 ) = 13
Hope This Helps :)
Answer:
f(5) = 13
Step-by-step explanation:

Solve for the roots in simplest form using the quadratic formula:
4x^2 -28x= -53
Answer:
x = (28 +- root -64) / (8)
Step-by-step explanation:
4x^2 -28x= -53 = 0
x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4
x = (28 +- root 784 - 848) / (8)
x = (28 +- root -64) / (8)
A dental hygienist is a health-care professional who works alongside a dentist to meet the oral health care needs of patients. Asked by one of her clients who needs to get a cavity filled what the average number of cavities a person gets filled by the time they are 50 years old, the hygienist responds that she will gather and determine not just the average, but also the median and the mode - because she would like to know this information herself. A bit of research turns up the following data table taken from a research project of a graduate student. The graduate student surveyed 20 people aged 50 from around Idaho.
Patient ID# Cavities Filled
1 1
2 8
3 7
4 9
5 11
6 12
7 7
8 5
9 2
10 0
11 8
12 9
13 7
14 6
15 8
16 9
17 8
18 9
19 8
20 8
a. What is the mean (average) number of cavities a person gets filled by age 50?
b. What is the median number of cavities a person gets filled by age 50?
c. What is the most often an occurring number of cavities filled in this data set?
Answer:
a. The mean number of cavities a person gets filled by the age of 50 is 7.1.
b. The medium number of cavities a person gets filled by the age of 50 is 8.
c. The most occuring number of cavities filled in the data set is 8.

x=y-8;5x+y=-4
Step: Solve x=y−8for x:
Step: Substitute y−8 for x in 5x+y=−4:
5x+y=−4
5(y−8)+y=−4
6y−40=−4(Simplify both sides of the equation)
6y−40+40=−4+40(Add 40 to both sides)
6y=36
6y /6 = 36/ 6 (Divide both sides by 6)
y=6
Step: Substitute6foryinx=y−8:
x=y−8
x=6−8
x=−2 (Simplify both sides of the equation)
x=−2 and y=6

Triangle ABC ~ Triangle DEF, which of the following is a conclusion that can be drawn?
A. AB/AC=DE/DF
B. AB/DE=CA/DE
C. BC/AB=DE/EF
D. BC/AC=EF/DE
Please help I don’t know how to do this
Answer:
12. 7
13. 6
Step-by-step explanation:
Answer: 12. x =7 13. x =6
Step-by-step explanation:
Both angles in the triangle has to equal to each other because they are both equivalent.
Set both expressions equal to each other and solve for x.
12. 5x = 35 Divide both sides by 5
x = 7
13. 3x = 5x - 12 Subtract 5x from both sides
-5x -5x
-2x = -12 Divide both sides by -2
x = 6

g Which statement is correct? Group of answer choices A sample size of 1 is never acceptable. Judgment sampling is preferred to systematic sampling. Cluster sampling is useful when strata characteristics are unknown. Sampling without replacement introduces bias in our estimates of parameters.
Answer:
A sample size of 1 is never acceptable
Explanation:
A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.
