Answer:
x=−y+
−1/2
Step-by-step explanation:
Let's solve for x.
y−4x−3y=−2x+1
Step 1: Add 2x to both sides.
−4x−2y+2x=−2x+1+2x
−2x−2y=1
Step 2: Add 2y to both sides.
−2x−2y+2y=1+2y
−2x=2y+1
Step 3: Divide both sides by -2.
−2x
−2
=
2y+1
−2
x=−y+
−1/2

Slope 7; (4,-30 equation
Answer: y=7x-68
Step-by-step explanation: Ok so you would use point slope to slope so plug the points in. y+30=7(x-4) then if you need to convert it further into slope intercept form just simplify and distribute. So y+30=7x-28, subract 30 from both sides to get y=7x-68
Hence, the slope of line is [tex]y=7x-58[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be easily determined by finding the difference between the coordinates of the points.
The slope is usually represented by the letter ‘m’.
Here given that,
Slope is [tex]7[/tex] and the coordinates of [tex](x,y)=(4,-30)[/tex].
As we know slope of line is
[tex]y=mx+c[/tex]
where [tex]m[/tex] is the slope.
So,
[tex]y+30=7(x-4)[/tex]
Now convert it further into slope intercept form
[tex]y+30=7x-28\\\\y=7x-28-30\\\\y=7x-58[/tex]
Hence, the slope of line is [tex]y=7x-58[/tex].

help asap i’ll be giving a brainliest to the person with the correct answer
Answer:
All of the above.
Step-by-step explanation:
By looking at the graph and taking point x at 4 and y at around 300. This shows us the precise rate of the graph which is when x = 4, y is equal to 300.
Now if we substitute the x as 4 in any of the equations we will get values larger than 300. Therefore, all the equations have a greater rate of change.
y = 85(4) = 340 (Greater)
y = 50(4) + 150 = 350 (Greater)
y = 65(4) + 100 = 360 (Greater)

3( 2p - 5) - 6p
need help please
Answer:
-15
Step-by-step explanation:
We have the expression 3(2p - 5) - 6p and are asked to simplify.
Let's distribute, which is to multiply a number that is outside of a parenthesis bracket by the numbers inside the parenthesis.
3(2p - 5) - 6p
(3(2p) - 3(5)) - 6p
6p - 15 - 6p
Since you can only do changes to like terms and 15 and 6p are two different terms, we do 6p - 6p.
6p - 6p
0
Leaving us with -15.
Answer:
-15
Step-by-step explanation:
Simplify each term.
6p - 15 - 6p
Combine the opposite terms:
Subtract 6p from 6p
0 - 15
Subtract 0 from 15
-15

A rental car agency charges $160.00 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $340.00?
Answer:
720 miles
Step-by-step explanation:
let 'm' = # miles you can travel for $340
340 = 160 + .25m
180 = .25m
m = 180/.25
m = 720
The weight (in kg) of cubical block of ice 75 cm in length (if one cubic metre of ice weight is 80 kg) is
(1) 35
(2) 42.50
(3) 33.75
(4) 40
Answer: The weight = 33.75kg
Step-by-step explanation:
Given that
one cubic metre of ice weight is 80 kg
which is mathematically written as
1m³ of ice = 80 kg
Therefore 75 cm length of cubical block of ice =???
First
changing 75 cm to meters, we have 75/100 = 0.75 m
Volume of block = l³= 0.75³ = 0.421875m³
Given that
1m³ = 80kg
0.421875m³= 0.421875 x 80
= 33.75kg
The probability of tails of a weighted coin is 0.8. The number of tails is noted each of the 20 times the coin is tossed. If this procedure is repeated 75 times, what type of distribution is simulated?
Answer:
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Step-by-step explanation:
We are given that
The probability of tails of a weighted coin, p=0.8
n=20
We have to find the type of distribution is simulated if this procedure repeated 75 times .
Random variable is a proportion of number of tails therefore, type of distribution is sampling distribution of the sample proportion.
We have n=20 and p=0.8
Hence, we can say that type of distribution is simulated is given by
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Answer:
I chose answer D. A binomial distribution with n=20 and p=0.8, No clue if correct or not
