which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?
Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation [tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)

Answer:
(2,10)
Step-by-step explanation:
so we can substitute the y = 5x into y = 6x - 2
so we would have
5x = 6x - 2
subtract 6x from both sides
-x = -2
remove the negative signs since they're on both sides
x = 2
so now we can substitute x = 2 into y = 5x
so we would get
y = 5(2)
y = 10
So the point will be (2,10)
Check:
y = 6x - 2
10 = 6(2) - 2
10 = 12 - 12
10 = 10
y = 5x
10 = 5(2)
10 = 10
Answer:
(2, 10)
Step-by-step explanation:
substitute the given value of y into the equation (y=5x)
6x-2 =5x
solve for x
"add" the -2 to the other side to leave the x by itself on one side
6x=5x+2
"subtract" the 5x to the other side to combine the x's
6x-5x=2
collect like terms
x=2
so you now have your x to solve for y
substitute the x into the equation (y=5x)
y=5(2)
simple
y=10
and there you have it!!

I'm doing a math test, and I don't understand this question. How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height of 2 1/3 inches?
Answer: 62
Step-by-step explanation:
First and foremost, we have to calculate the volume of the box which will be:
= 2 2/3 × 3 1/3 × 2 1/3
= 8/3 × 10/3 × 7/3
= 560/27
= 20 20/27
The number of 1/3 inch cubes needed to fill the box will then be:
= 20 20/27 ÷ 1/3
= 560/27 ÷ 1/3
= 560/27 × 3
= 560/9
= 62 2/9
Therefore, 62 boxes can be filled
F(x)=3x-2 find f^-1(x) than find f^-1(13)
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 3x - 2 ( add 2 to both sides )
y + 2 = 3x ( divide both sides by 3 )
[tex]\frac{y+2}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x)
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]
To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is
[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5

Dustin wants a new pair of shoes that cost $40. His mom pays 75% of the cost and dustin pays 25%. How much do they each pay?
Given:
Dustin wants a new pair of shoes that cost $40.
His mom pays 75% of the cost and dustin pays 25%.
To find:
How much do they each pay?
Solution:
We have,
Total cost of shoes = $40
His mom pays 75% of the cost.
[tex]\text{Mom pays}=\dfrac{75}{100}\times 40[/tex]
[tex]\text{Mom pays}=\dfrac{3}{4}\times 40[/tex]
[tex]\text{Mom pays}=30[/tex]
Dustin pays 25% of the cost.
[tex]\text{Dustin pays}=\dfrac{25}{100}\times 40[/tex]
[tex]\text{Dustin pays}=\dfrac{1}{4}\times 40[/tex]
[tex]\text{Mom pays}=10[/tex]
Therefore, Dustin pays $10 and his mom pays $30.

pls help or else I’m screwed.
Answer:
D. x = 18 cm , y = 9
Step-by-step explanation:
With reference angle 60
perpendicular (p) = 9[tex]\sqrt{3}[/tex]
base(b)= y
hypotenuse (h) = x
Then
sin 60 = p/h
[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]
x = 18
Now
cos 60 = b/h
1/2 = y/18
y = 9
Hope it will help :)
Answer:
it's answer is
D. = 18 and y = 9
