Jill converted the equation of the line 15x-4y=-2 into slope-intercept form and found the slope and y-intercept of the line
as follows.
What was her Mistake?
She Mixed Up the slope and the y-intercept.
She got the sign of the slope wrong.
She git the sign of the y-intercept wrong.
She found reciprocals of the slope and the y-intercept.
ASAP Please Right Answer
Answers
Answer:
She got the sign of the slope wrong
Step-by-step explanation:
She did [tex]\frac{-4y}{-4} = \frac{-2-15x}{-4}[/tex] and turned that into [tex]\frac{-2}{-4}-\frac{-15x}{-4}[/tex], which is wrong, because she did the negative twice. Therefore, she mixed up the sign of the slope.

A concert charges $30 admission and $15 per shirt. Alyssa paid $75 at the concert for her admission and shirts. Write and solve an equation to find the number of shirts Alyssa bought. Explain what your variable represents.
Answers
Answer:
75-30/15=x
Step-by-step explanation:
75-30=45
45/15=3
75-30/15=x
Answer:
30+15(x)=75 so x would =3
Step-by-step explanation:
So you have one ticket which is $30, then you add 15 times however many shirts she buys which in total will equal $75. She would have bought 3 shirts. So 30+ 15(3)=75. Hope that helps!

Quan makes $72 a day as an Uber driver, plus $8 for each client he has. If
Quan typically makes $104 a day. How many clients does he usually have
Answers
Answer:
Quan usually has 4 clients
Step-by-step explanation:
Working backward at math is to start with the final situation and work back one step at a time to get to the beginning.
We know Quan makes $104 a day, including his $72 fixed rate plus an $8 rate per client.
Subtracting the total and the fixed rate, we can find the variable part of his earnings.
$104 - $72 = $32
Quan usually makes $32 for the variable rate at $8 per client, thus he usually has $32 / $8 =4 clients.
Quan usually has 4 clients

A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm 3 , what is the mass of the gas in the tube in mg?
Answers
Answer:
0.125214 gStep-by-step explanation:
we know that density is given as
density=mass/volume
the volume of the cylinder
v= πr^2h
v=3.142*1.5^2*14.4
v=3.142*2.25*14.4
v=101.8cm^3
Given that density =0.00123g/cm^3
mass= density*volume
masss= 0.00123*101.8
mass= 0.125214 g

Write the equation of the line that is parallel to y = 9x+ 4 and crosses the y-axis at -3.
Answers
9514 1404 393
Answer:
y = 9x -3
Step-by-step explanation:
The given line is in "slope-intercept form"
y = mx + b
where m is the slope and b is the y-intercept (where it crosses the y-axis).
In your given line, we have ...
m = 9, b = 4
__
A parallel line will have the same slope, so we know that the line you want has m = 9. You are told to make the line cross the y-axis at -3, so that makes b = -3. Putting these values into the slope-intercept form gives the desired equation:
y = 9x -3
_____
The attached graph is intended to show the lines are parallel and the equation given here meets the requirement for a crossing of the y-axis at -3. The vertical and horizontal scales are different in order to better show these things.

Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
