=============================================================
Explanation:
Because we're given multiple choices to pick from, we can go through each to do trial and error.
For instance, if v = 52, then
v/13 < -7
52/13 < -7
4 < -7
but that's a false statement since 4 is not smaller than -7. Use a number line to see this. You should have -7 to the left of 4, showing that -7 is the smaller value.
Because 4 < -7 is false, this means v/13 < -7 is false when v = 52. This rules out v = 52. You should find that v = 26 and v = -39 won't work for similar reasons.
Only v = -130 works since...
v/13 < -7
-130/13 < -7
-10 < -7
This is true because -10 is to the left of -7 on the number line.
-------------------------------------------------
Another approach:
We have some unknown number v, and we're dividing by 13 to get the expression v/13. To undo this, we multiply both sides by 13
v/13 < -7
13*(v/13) < 13*(-7) .... multiply both sides by 13
v < -91
So any solution to the original inequality must be smaller than -91. This allows us to rule out v = 52, v = 26 and v = -39.
The value v = -130 is smaller than -91, so it satisfies v < -91. Therefore, v = -130 is a solution to the original inequality.

can somebody tell me the answer to my question plssss I need to know what the dependant variable is
Answers
Answer:
Hey Hey here you go!
according to the chart thing y is the plane and x is hours
Question A- so the plane(y) goes 600 miles x hours. it says 600 per hour so 600 miles an hour.
Question B- the dependant vriable is 6 from 600. why? because it was the main source for the eqauation and we used it to subract 300 from to get the next answer.
Question C- 600 miles x 600 miles is 1,200 miles. wich would be 1,200 miles for two hours. it said two and a HALF hour so half of 600 is 300 so add that to 1,200 + 300 is 1,500 miles in 2.5 hours (two and a half hours.)

A class contributed $8.40 in dimes and quarters to the Red Cross. In all, there was 45 coins. How many coins of each kind were there?
Please also give an explanation. 50 points are a big deal.
Answers
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19
26 quarters
19 dimes
Answer:
Step-by-step explanation:
Let d = # of dimes

Then plug in the value for d into the second equation.

Answers
We need them to be same denominators so we multiple the first fraction by 3, to give 9/12.
9/12+1/12=10/12
if we simplify that fraction by dividing it by 2:
10/12= 5/6

72. |x - 3x5| = 6 + y

Answers
Answer:
Step-by-step explanation:
|x-3x^5|=6+y
y<0
|9-y+6|=21
|15-y|=21
15-y±21
either 15-y=21
-y=6
y=-6
or 15-y=-21
y=36
but y<0
so y=-6
|x-3x^5|=6+y
|x-3x^5|=6-6
|x-3x^5|=0
x-3x^5=0
x(1-3x^4)=0
either x=0
or 1-3x^4=0
or (1-√3 x²)(1+√3x²)=0
1-√3 x²=0
x²=1/√3
x=±√(1/√3)
x²=-1/√3
x=±(1/√3)i
