The last one, because when you have to solve an equation, first you have to rearrange the equation, so that all the n’s are on one side of the equation and the numbers are on the other. Then, you just divide both sides by the number multiplying n to find the value of just one n. I hope this helped! I even included another example question that explains it a bit better.
Explanation:
The scale factor must be greater than 1 because the image of the segment is larger than the original segment.
To find the scale factor we just have to divide the length of the image by the length of the segment:
Answer:
(4) 4
D. 200%
if 8 is a whole (100%) and 16 is twice of that, you can conclude that her speed increased by 200%
Answer:
Mean
Step-by-step explanation:
The mean is the average so practically meaning most in this case.
Not muslim but felt like I could help
Answer:
see step-by-step below
Step-by-step explanation:
1) y - 2 > 3
Add 2 to both sides: y > 5
2) y ≤ 2
Draw a closed circle at y = 2 then shade the numbers to the left
3) y ≥ 250
where y = savings
4) The image isn't very clear, so I can't tell if it's a closed or open circle on -4.
If it is closed, it will be y ≤ -4
If it is open, it will be y < -4
5) -4 < f
Draw an open circle at f = -4 then shade the numbers to the right
6) x < -3.5
Draw an open circle at x = -3.5 then shade the numbers to the left
7) closed circle ... shade to the left of 8 ... make y equal to or less than 8.
8) F ≤ 6
C - closed circle at 6 with shaded numbers to the left
9) y > 2.75
Betty saved more than $2.75 every month
10) 1 + x < 5
Subtract 1 from both sides: x < 4
11) x ≥ -2.5
12) 1 ≤ m means that m is equal to or greater than 1
solutions: 4, 1, 2.3
