Answer:
20 feet
Step-by-step explanation:
We can use scale factors to represent the lengths. Since the flagpole's base is 4 times the tree's height, we can also say that the flagpole's height is 4 times the tree's height. Since the tree's height is 5 feet, the flagpole's height is 4 x 5, which is 20.

So if we add both the equations 5x will be eliminated.
5x + 4y - 5x - 2y = 4 + 2
4y - 2y = 6
2y = 6
y = 3
As y is 3
x will be

what solution does the equation |4x+7|=-3 have
Answers
The result of an absolute value function is never negative. This is because absolute value represents distance on a number line, and negative distance is not possible. Negative distance doesn't make sense.
So we don't have solutions to something like |x| = -5 or the given equation. The right hand side must be 0 or a positive number if you want to have at least one solution.

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?
Answers
Answer:
2.75
Step-by-step explanation:
Here, we want to find which part of the formula corresponds to the cost of movie tickets in 1980
The expression to find the cost is
2.75 + 0.10x
Now, x is the time since 1980
1980 is thus the starting position. The value of x at this point is 0, we simply thus make a substitution;
2.75 + 0.1(0)
=
2.75
The interpretation of the given model is required.
The cost of a movie ticket in the year 1980 was $2.75.
The given expression is
[tex]y=2.75+0.1x[/tex]
The point slope form of a line is
[tex]y=mx+c[/tex]
where,
m = Slope
c = Y intercept
The cost of movie ticket increases by $0.10 every year after 1980.
Here, [tex]x[/tex] is the number of years that have passed after 1980.
So, when [tex]x=0[/tex] it will correspond to the cost of ticket in 1980.
[tex]y=2.75+0.1\times 0\\\Rightarrow y=2.75[/tex]
The cost of a movie ticket in the year 1980 was $2.75.

What is the average rate of change of the line?
Answers
Answer:
- 12
Step-by-step explanation:
The slope of the line is a measure of the average rate of change
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 12(x + 4) ← is in point- slope form
with slope m = - 12 ← average rate of change

Please help!!! How many pages can be read in 45 minutes? Answer with a decimal point rounded to the nearest tenth if necessary.
Answers
Answer:
157.5 pages
Step-by-step explanation:
First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:
2m = 7
--- --- <---- Here we divide both sides of the equal sign by 2
2 2
m = 3.5 <---- we read 3.5 pages per minute
45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.

Answer:
The length is 42 inches and the width is 14 inches
Step-by-step explanation:
You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.
You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.
Then you subtract 2y from both sides to get the unit value of y.
Y is equal to 18.
Then you can plug 18 into the y's to get
2(18)+6 which is 36+6 = 42
18-4 = 14
There you go.
The length is the longer side which is 42 inches and the width is 14 inches

Answers
Answer:
x=.3 or 3/10
Step-by-step explanation:
to solve for x, we need to separate it
so, we add 13 to the left side
40-11x=x
then add 11x to the right side so we have different coefficients on each side to solve for x
40=12x
then we divide 40/12 to get what x equals
we get
x= 0.3 or 3/10
hope this helped!
Answer:
x=10/3
Step-by-step explanation:
27 - 11x = x - 13
27+13=x+11x

X = 70 degrees
Step-by-step explanation:
The way to figure this out is by taking the angle of the 30 degrees and applying it to the opposite side of its self then just add it to the 80 degrees which will equal 110 and since a straight line has 180 degrees just subtract 180 by 110 and that will be the value of x because the lines are parallel and the line that goes through both lines will always have the same angle.
