Solve using substitution.
4x - 5y = 1
x = -6
Answer:
y = -5
Step-by-step explanation:
To solve by using substitution, first substitute x for -6 in the equation 4x-5y=1
4(-6)-5y=1 start by simplifying this problem
-24-5y=1 now you can solve for y, add 24 on both sides
-5y=25 now divide -5 on both sides
y= -5
Use opposite operations to solve 3/4 x=6
Answer:
x=8
Step-by-step explanation:
3x/(4 x 4) =6(4)
cancel the four in the left side
3x=24
then divide 3 on both sides
3x/3=24/3
cancel the 3 on the left
x=8

Answer:
72
Step-by-step explanation:
The answer is 72 because it is a simliar triangle, all the sides are proportional to each other. 45/5=9, 63/7=9, so the factor is 9. 9 times 8 is 72.
Find the slope of the line that passes through (6, 7) and (1, 11).
Answer: -4/5
Step-by-step explanation:
Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
In order to find the answer to this question you must to use the formula of slope, substitute the values, and then solve.
[tex]slope = \frac{y2-y1}{x2-x1}[/tex]
[tex]P1=(6,7)=(x1,y1)[/tex]
[tex]P2=(1,11)=(x2,y2)[/tex]
Substitute:
[tex]\frac{11-7}{1-6}[/tex]
Solve:
[tex]11-7=4[/tex]
[tex]1-6=-5[/tex]
[tex]=\frac{4}{-5}[/tex]
Simplify:
[tex]\frac{4}{5}[/tex]

The seventh grade enrollment at Goddard increase from 380 to 456 students. What is the percentage of increase?
Answer:
The percentage of increase is minus.
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
If it increased from 380 to 456, first you need to find the difference.
456 - 380 = 76
Now, you must divide the original number by 76, which is 380.
76/380 = 0.2
Convert 0.2 to a percentage.
0.2 = 20%
The seventh grade enrollment at Goddard increased by 20%.
I hope it all works out well for you in your class :)

Which type of compound inequality is |y−3|−4≤−3?
a.) disjunction
b.) intersection
c.) hole
d.) union
Answer:
b.) intersection
Step-by-step explanation:
The given inequality can be rearranged so that you can see the solution space is one continuous interval.
__
It is described by the intersection of two inequalities.
|y -3| -4 ≤ -3 . . . . . . given
|y -3| ≤ 1 . . . . . . . . add 4
-1 ≤ y -3 ≤ 1 . . . . . "unfolded", the intersection of two inequalities
2 ≤ y ≤ 4 . . . . . . . add 3
This means 2 ≤ y and y ≤ 4, the intersection of the two inequalities.
_____
Additional comment
If the inequality were of the form ...
|y -3| ≥ 1
then it would "unfold" to ...
-1 ≥ y -3 or y -3 ≥ 1
and the solution intervals would be disjoint. The solution would be the union of the solution intervals of the individual inequalities.
Answer:
intersection is right

Traverion wants to find the answer to the question "How much money does the average college professor make?" He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university
Step-by-step explanation:
Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.
Therefore for him to have accurate result he have to survey professors from different area which will inturn give him the accurate sample

Michael says that 5(153)=5(53). Is his answer correct? Explain. A. Yes; Both expressions are equal to 625. B. Yes; Both expressions are equal to 125⋅ C. No; The first expression is equal to 125 and the second expression is equal to 625. D. No; The first expression is equal to 625 and the second expression is equal to 125.
Answer:
Michael's answer is not correct
5(153)≠ 5(53)
Step-by-step explanation:
Michael says that 5(153)=5(53)
Is his answer correct?
We solve for the left hand side
5(153) = 5 × 153
= 765
Solving for the right hand side
= 5(53) = 5 × 53
= 265
Therefore, from the above calculation,
5(153)≠ 5(53)
5(153) is not equal to 5(53)
Michael's answer is not correct

A)There is no bias in this survey because the students were randomly chosen.
B)There is nonresponse bias because the results underestimate the true percentage of students who complete their homework nightly.
C)There is response bias because the results underestimate the true percentage of students who complete their homework nightly.
D)There is convenience sampling bias because the results overestimate the true percentage of students who complete their homework nightly.
E)There is voluntary response bias because the results overestimate the true percentage of students who complete their homework nightly.
