Please look at number 10. from the slope and write the equation for me
Answers
Answer:
y = 8x + 38
Step-by-step explanation:
To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)
y = mx + b
y = 8x + b
6 = 8(-4) + b
6 = -32 + b
+32 +32
38 = b
So using our slope and our intercept we have our slope intercept
y = mx + b
y = 8x + 38
Hope this helps :)
Answer:
y - y1 = m(x - x1)
y - 6 = 8(x - (-4))
y - 6 = 8(x + 4)
y - 6 = 8x + 32
y = 8x + 32 + 6
y = 8x + 38
Step-by-step explanation:
First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.
After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.
Then you add 6 to both sides of the equation to isolate the y.
The slope-intercept equation ends up looking like this: y = 8x + 38

find the length of a diagonal AB in the rectangular prism
Answers
Hi there!
[tex]\large\boxed{AB = 32.60 in}[/tex]
Find the length of AB by finding the length of its base:
We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:
sin = O / H
sin 50° = 24 / H
h * sin 50° = 24 ----> h = 24 / (sin 50°)
h ≈ 31.33 in
Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:
c² = a² + b²
c² = 31.33² + 9²
c² = 1062.57
c ≈ 32.60 in
AB = 32.60 in
What is the answer to this question.

How do i find the variable
Answers
Answer:
there are two variables x and y which variable do u need to find or do u need it in point slope form
Answer:
Simplifying
6x + 3y = 54
Solving
6x + 3y = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
6x + 3y + -3y = 54 + -3y
Combine like terms: 3y + -3y = 0
6x + 0 = 54 + -3y
6x = 54 + -3y
Divide each side by '6'.
x = 9 + -0.5y
Simplifying
x = 9 + -0.5y

Answers
Answer:
Pretty sure its undefined
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
Looking at the change in x's theres no variation which means this is a vertical line, thus therefore this is an undefined line as the rise over the run or the change in y over the change in x will result in a divide by 0 situation making it (-4, all real numbers) aka undefined.
slope = rise/run = change in y/change in x = (y2-y1)/(x2-x1)

Suppose (ideally) a hammer claw moves a distance of 0.10 meters to remove a nail. If a resistance force of 1500 N is exerted by the claw, and you move the handle of the hammer 0.5 meters, what is the effort force?
Answers
Answer:
7500 N
Step-by-step explanation:
Given that,
A hammer claw moves a distance of 0.10 meters to remove a nail.
Resistance force, F = 1500 N
The person move the handle of the hammer 0.5 m
We need to find the effort force. Let it is F'. The mechanical advantage is given by :
[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]
Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.
[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]
So, the effort force is 7500 N.

a pool of linen container 100 meters. three butete brought 15.75 meters, 22.50 meters and 12.25 meters respectively. how many meters of line was left after the sale
49 m
Answers
Answer:
49.5 meters of linen were left after the sale.
Step-by-step explanation:
Given that there are 100 meters of linen
And 15.75, 22.50 and 12.25 meters are sold.
This means that the sold linen has to be added to find the total linen sold.
And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.
[tex]Total\ linen\ sold = 15.75+22.50+12.25 = 50.5\ meters[/tex]
Left linen will be:
[tex]=100-50.5 = 49.5[/tex]
Hence,
49.5 meters of linen were left after the sale.
