1. Which of the following values of n will make the below equation true? n × (−2+5 ) = −8+20
a. 4 b. -4 c. 3 d. 12
2. What value of n will make the following equation true? 2 + (n+6) = −1+6
a.-3 b.-1 c.5 d.8
Answer:
1a 2a
Step-by-step explanation:
n × (−2+5 ) = −8+20
n × 3 = 12
n = 4
2 + (n+6) = −1+6
n + 8 = 5
n = -3

A local employer asked for help selecting a new type of desk chair. Thirty employees volunteered, and each employee used the new desk chair for two weeks and the current desk chair for two weeks. To determine which chair was used first, a coin was flipped for each employee. Heads represented using the new chair first, and tails represented using the current chair first. At the end of each two-week period, the employees were asked to rate their satisfaction with the new chair. Which of the following best describes this study?
Answer:
E-It is a well-designed experiment because there is random assignment, replication, and comparison of at least two treatment groups.
Random assignment, replication, and the ability to compare at least two treatment groups are all criteria for a well-designed experiment.
Solve for x: 7x-3/5x-2 = -2
Step-by-step explanation:
★ Solution:-[tex]\sf \leadsto \dfrac{7x - 3}{5x - 2} = -2[/tex]
[tex]\sf \leadsto 7x - 3 = -2(5x - 2)[/tex]
[tex]\sf \leadsto 7x - 3 = -10x + 4[/tex]
[tex]\sf \leadsto 7x + 10x = 4 + 3[/tex]
[tex]\sf \leadsto 17x = 7[/tex]
[tex]\sf \leadsto x = \dfrac{7}{17}[/tex]
Hence the value of x is 7/17
Mahni plans to spend the next 12 weeks saving some of her income. She will save $x a week for the first 6 weeks and then $(2x − 30) a week for the following 6 weeks. If she managed to save $213 in the first six weeks, how much did she save in total over 12 weeks? Explain correctly how to do this to get Brainliest ANSWER
For first six weeks she saved 213$
Now
For next 6weeks
[tex]\\ \sf\longmapsto 2x-30=2(213)-30=426-30=396\$[/tex]
Total savings:-
.[tex]\\ \sf\longmapsto 396+213=609\$[/tex]
Answer:
$459Step-by-step explanation:
Mahni saved 6x in the first 6 weeks which is $213.
She saves in the next 6 weeks:
6*(2x - 30) = 12x - 180 = 2*6x - 180 = 2*213 - 180 = 246Total saving is:

_To solve an absolute value inequality what do I have to do to the absolute value symbols?
a) Isolate
b)keep
c)flip
Answer:
c) flip
Step-by-step explanation: When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! hope this helps!!

2. Stephen Curry's record during the 2017 – 2018 NBA final game is made up of 2-point shots and 3-points.
His total points scored for the final game was 45 points with 19 shots made. How many 2-point shots did
he make? How many 3-point shots did he make?
Answer:
He made 7 3-point shots.
Step-by-step explanation:
x+y=19
2x+3y=45
y=19-x
2x+3*(19-x)=45
2x+57-3x=45
-x=45-57
-x=-12
x=12
y=19-12
y =7
Decomposition, find f(x) and g(x) so that the function can be
described as y = f(g(x))
y = (x – 4) + 5
f(x)=
g(x) =
Answer:
steps below
Step-by-step explanation:
f(x) = x + 5
g(x) = x - 4
f(g(x)) = f(x-4) = (x-4) + 5
State the equation of the line described.
A line passes through the point (-3,7) and is perpendicular to the line y = -9x + -1.
thanks for your help!
Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. This means that when you multiply the slopes of the perpendicular lines, its product = -1.
Given the linear equation, y = -9x - 1, and the point, (-3, 7):
Since the slope of the given linear equation is: m1 = -9, then it means that the slope of the other line (m2) = 1/9:
m1 × m2 = -1
-9 × 1/9 = -1
Next, we need to find the y-intercept of the other line. The y-intercept is the point on the line where it crosses the y-axis, and has coordinates (0, b). It is also the value of the y-coordinate when its corresponding x-coordinate = 0.
Using the given point, (-3, 7), and the slope of the other line, m2 = 1/9:
We need to substitute these values into the slope-intercept form, y = mx + b, to solve for the y-intercept, (b):
y = mx + b
7 = 1/9(-3) + b
7 = -1/3 + b
Add 1/3 to both sides of the equation to solve for b:
7 + 1/3 = 1/3 -1/3 + b
22/3 = b
Therefore, the y-intercept (b) = 22/3.
The linear equation of the other line is: y = 1/9x + 22/3
Which is an equation of the line that
passes through the point (5,-2) and has a
slope of.-3?
A y=-3x - 13
C y = 3x – 13
Dy=-3x + 13
B y = 3x + 13

Answer:
2/1 or 2
Step-by-step explanation:
so first, you have to count the rise/run. This line rises up 2 and runs to the right 1. To find out the rise/ run, find a place in the graphed line where it is on a plot point. For example: (40, 30). Then just see how much it rises and how much it runs.
what property is -6+24=x-24+24
Answer:
x = 30
Step-by-step explanation:
-6 + 24 = x - 24 + 24
x = 24 + 6 - 24 - 24
x = 30 - 0
x = 30

witch one is bigger?
pls explain it
Answer:
The six is bigger
Step-by-step explanation:
They both are inside the absolute value sign, meaning, the the numbers are negative, they will turn positive and if they are positive, then they will remain positive. So, in this case 4 and 6 are both positive and remain positive. And obviously 6 is greater than 4 because 6 comes after 4 in a number line.
