Every hour, a machine makes the same number of tennis racquets. If on the 3rd hour of running, the machine has made 240 racquets, and on the 5th hour of running it has made 400 racquets, what is machines production rate?
A
80 racquets per hour
B
100 racquets per hour
C
120 racquets per hour
D
140 racquets per hour
Answer:
80 racquets per hour.
Step-by-step explanation:
Divide 240 by 3, and you'll get 80. To double check, divide 400 by 5 and you'll still get 80. Hope that helps.
What is the equation of the line that has a slope of m = 2 and passes through the point (-5, -6)?
Answer:
[tex]y=2x+4[/tex]
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
Point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where:
[tex]m[/tex] is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]
Solve for y. Expand the right sie using the distributive property:
[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]
OR
Slope-intercept form:
[tex]y=mx+b[/tex]
Where:
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept[tex]x[/tex] and [tex]y[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]
Simplify the multiplication:
[tex]-6=-10+b[/tex]
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
[tex]-6+10=-10+10+b\\\\4=b[/tex]
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
[tex]y=2x+4[/tex]
:Done
solve for x: 5x - 2 = 3x + 8
Answer:
x = 5
Step-by-step explanation:
To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)
2x - 2 = 8 now add 2 to 8
2x = 10 now divide 2
x = 5
I hope this helped :)

Step-by-step explanation:
solve for c: 16c - 7 = 13.32
16c - 7 = 13.32
16c = 13.32 + 7
16c = 20.32
c = 20.32/16
c = 1.27

15/20
20/20=1 help please
Answer:
20/20: D
Step-by-step explanation:
First turn both the fractions into twentieths.
3/5 = 12/20
8/20
Then add 12/20+8/20=20/20
20/20 = 1

Answer:
A and D are functions
Step-by-step explanation:
A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)
B is not a function because there isn't a constant for y.
C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.
D is also a function because of the equation on the right side.
The red line of the attachment below in A's function graphed, and the lime curve represents D's function graphed.

How can you determine the sale price if you are given the regular price and the percent of markdown
Answer:
Step-by-step explanation:
Take original price divide by one hundred multiply that by percentage, subtract what you get from original price and that’s your sale price
Answer:
let's say the price is 400 dollars
and the percent of markdown is 20%
100-20=80
400x80=32000
32000/100= 320
The price will be 320 dollars.
