========================================================
Explanation:
The two points on this line are (-1,5) and (0,1)
Let's use the slope formula
m = (y2-y1)/(x2-x1)
m = (1-5)/(0-(-1))
m = (1-5)/(0+1)
m = -4/1
m = -4
The slope is m = -4
If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run
The y intercept is b = 1 since this is the location where the graph crosses the y axis.
With m = -4 and b = 1, we go from y = mx+b to y = -4x+1
75% of the items collected at the food drive were cans of soup. If 90 cans of soup were
collected, how many items were collected in all?
Answer:
67.5
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
If 90 cans of soup were collected and it was 75%, take 90/3=30. If 25% of all cans is 30 then when you multiply by 4, to get 100%, you have 120 cans. Also 120/75%= 90

Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
A fraction is in simplest form when no other factor but 1 will divide into the numerator/ denominator
[tex]\frac{5}{10}[/tex] ← divide numerator/ denominator by 5
=[tex]\frac{1}{2}[/tex]
[tex]\frac{4}{5}[/tex] ← is in simplest form
[tex]\frac{6}{10}[/tex] ← divide numerator/denominator by 2
= [tex]\frac{3}{5}[/tex]
[tex]\frac{8}{12}[/tex] ← divide numerator/denominator by 4
= [tex]\frac{2}{3}[/tex]
[tex]\frac{4}{5}[/tex] is the only fraction given in simplest form
Luis rides his bicycle 34 mile in 15 minutes, or 14 hour, along the bike trail.
Assuming he rides at a constant rate, what is his speed, in miles per hour? Use the table to help find the answer.
Enter your answer in the box.
Miles 34 ?
Hours 14 ?
miles per hour
Luis' speed in miles per hour is 136.
What is speed?Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.
By dividing the miles he cycled by the hours he traveled, one may calculate Luis' speed in miles per hour.
Because the measurement must be in miles per hour,
the time would be expressed in hours rather than minutes.
Speed = distance / time
Distance = 34 miles
Time = 15 minutes.
Speed = 34 ÷ 15 miles per minute.
Speed = 34 ÷ 1/4 miles per hour.
Now, speed = 34 x 4 miles per hour.
Therefore, Luis' speed is 136 miles per hour.

What is the value of x in the figure?
A. 10
B. 6
C. 15
D. 12
Answer:
Step-by-step explanation:
You need to set up a proportion.
(21 - 15) / 21 = 4/(x + 4)
6 / 21 = 4/(x + 4)
2/7 = 4/(x + 4)
2(x + 4) = 7*4
2x + 8 = 28
2x + 8-8= 28 - 8
2x = 20
x = 20/2
x = 10

The slope of a line is 6 and it goes through the point (4,5), which function is best
represented by this graph?
y = 6x - 29
y = 6x + 19
y = 6x - 19
y =6x + 29
Answer:
[tex]y=6x-19[/tex] is the function which best
represented by this graph.
The graph is also attached.
Step-by-step explanation:
As the point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
Given
m = 6 and the point (4, 5)
substituting the values in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 5 = 6 (x - 4)[/tex]
[tex]y - 5 = 6x-24[/tex]
[tex]y=6x+5-24[/tex]
[tex]y=6x-19[/tex]
Therefore, [tex]y=6x-19[/tex] is the function which best
represented by this graph.

Danny charges $22 for 2 hours of swimming lessons, Martin charges $90 for 5 hours of swimming lessons. Who offers a better deal?
Answer:
danny
Step-by-step explanation:
Danny charges $11 a hour while martin charges $18 a hour
Answer:
Danny offers a better deal
Step-by-step explanation:
Because you have to find out how much each person is charging for each hour of swimming lessons divide Danny's $22 by 2 to get $11 for one hour. And divide Martin's $90 by 5 to get $18 for one hour. Danny is giving you a better deal than Martin.

Well, if you x's are multiplication signs, then the answer is 628 because
6x100=600, 1x10=10, 7x1=7, 9x1=9, 2x1=2 and then add them all up:
600+10+7+9+2=628

Step-by-step explanation:
6x100= 600
1x10= 10
7x1= 7
9x1= 9
2x1= 2
600 + 10 = 610

#1) Mrs. Ebanks planted two trees on a
planning grid at coordinates (0,8) and
(12, 4). Determine the distance between
the trees using the given appropriate
formula.
show all work!
Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,
[tex]D=\sqrt{(12-0)^2+(4-8)^2}\\\\=\sqrt{144+16} \\\\=12.64\ m[/tex]
So, the distance between the two trees is 12.64 m.
Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

Negative numbers go first, the greater the number, the smaller the number.
Answer:
-√19,-3.5, √20, 4.9, 1/2
Step-by-step explanation:
Find the square root of 19 ( Which you can't) always have the negatives go first because negatives are the greatest. Find the square root of 20, which equals 4.4, then divided 3/2 which gives you 1.5. I hope this helped! I'm not the best at explaining either.
