What is the equation of a line .........
Answer:
y = -x + 2, B is the answer
Step-by-step explanation:
If slope is -1, the equation is y = -x+b
Plug in (3,-1) into that equation.
-1 = -3 + b
b = 2

The value of x in the expression
2x/3 - 7 = 5 is
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18

1. What is the prime factorization of 402? *
Your answer
Answer:
Step-by-step explanation:
Prime factorization requires dividing by primes starting with smallest prime number
402/2=201
201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is
2X3X67
A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
Answer:
13.8 ounces of salt
Step-by-step explanation:
A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
Step 1
Note that:
1 shaker = 0.6 ounces of salt
8 shakers = x
Cross Multiply
x = 8 × 0.6 ounces of salt
x = 4.8 ounces of salt
Step 2
The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
This is calculated as:
18.6 ounces of salt - 4.8 ounces of salt
= 13.8 ounces of salt

Write the equation of the line that passes through the points (4,7) and (8,6). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
Step-by-step explanation:
Find Slope: m = [tex]\frac{y_{2-}y_{1} }{x_{2-}x_{1} }[/tex]
m = [tex]\frac{6-(7)}{8-(4)}[/tex]
m = [tex]\frac{-1}{4}[/tex]
Point Slope Form: y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)

What do I do with e^y in the differential equation dy/dt =(2t)/(e^y)?
As you said, the equation is separable:
dy/dt = 2t / exp(y)
exp(y) dy = 2t dt
Integrate both sides:
∫ exp(y) dy = ∫ 2t dt
exp(y) + C₁ = t ² + C₂
Move the constant terms to one side. When you add them together, you get another constant, so you can ignore the subscript altogether:
exp(y) = t ² + C
Solve for y explicitly by taking the logarithm of both sides:
ln(exp(y)) = ln(t ² + C )
y = ln(t ² + C )
C can be any number; if it happens to be 0, then you have
y = ln(t ²) = 2 ln(t )
so B is the correct choice.
You can also approach this from the opposite angle: Assume y is one of the given solutions, then substitute it into the ODE. (Bit more trial-and-error involved, so not a good idea if you're short on time.)
For example, if y = 2 exp(t ) as in choice A, you have dy/dt = 2 exp(t ), so the ODE would become
2 exp(t ) = 2t / exp(2 exp(t ))
which is clearly (I hope) not true.
i need hell with this pleasee
If the perimeter of a rectangle garden with a width of 15 is 125, what is the perimeter of the daily record it if the scale factor is 60%
Answer:
(here i assume that the daily record is another rectangle)
For a rectangle with width W and length L, the perimeter is:
P = 2*W + 2*L
in this case we know that:
P = 125
W = 15
Replacing these in the perimeter equation we get:
125 = 2*15 + 2*L
125 = 30 + 2*L
125 - 30 = 2*L
95 = 2*L
95/2 = L = 47.5
Now we know that the daily record has a scale factor of 60%.
This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.
Then if the width of the daily record is W' and the length of the daily record is L'
This means that:
L' = (60%/100%)*L = 0.6*L = 0.6*47.5
W' = (60%/100%)*W = 0.6*W = 0.6*15
Then the perimeter is:
P' = 2*0.6*47.5 + 2*0.6*15 = 75
(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)
The rectangle shown has a perimeter of 98 cm and the given area. Its length is 7 more than 5 times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
35 is its width and 63 is its length.
Step-by-step explanation:
7 x 5 = 35 and 98 - 35 equals 63 which is the length.

people in here again and again. I think this is the last question
Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.
