A line contains the points (0,8) and (1.-2) What is the slope of the line in simplified form? Enter your answer in the box
Slope = change in y / change in x
Slope = (-2 -8) / (1-0)
Slope = -10/1
Slope = -10
Answer: slope = -10
Write equations for the horizontal and vertical lines passing through the point (-6,1)
Answer:
y = 1 and x = - 6
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (- 6, 1 ) with y- coordinate 1 , then
y = 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, 1 ) with x- coordinate - 6 , then
x = - 6 ← is equation of vertical line

15. (02.05 LC) Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) - 3? (1 point) The graph shifts 3 units up. The graph shifts 3 units down. The graph shifts 3 units left. 3 . The graph shifts 3 units right. 1-15 0
Will give brainliest
Answer:
the graph shifts 3 units down
Explanation:
to move a graph up c units, add c to the whole function
so basically what you did is you subtracted 3 from the whole function the whole graph shifts 3 units down
I hope it helps.
Find the indicated sum.
Answer:
-5
Step-by-step explanation:
The starting point is at 1 and the stopping is at 5(if you want to know where to find these, look at the image attached).
For i=1, we have i-4, which would be 1 - 4, or -3.
For i=2, we have i-4, which would be 2 - 4, or -2.
For i=3, we have i-4, which would be 3 - 4, or -1.
For i=4, we have i-4, which would be 4 - 4, or 0.
For i=5, we have i-4, which would be 5 - 4, or 1.
We would add these 5 values:
-3 + (-2) + (-1) + 0 + 1
This gives us -5

Suppose you are earning a salary of $62,000 per year in Illinois. Your employer asks you to transfer to the California office. Based on the average annual cost of living, what is the lowest possible salary you will accept? Round your answer to the nearest whole dollar. Explain your reasons.
9514 1404 393
Answer:
$74,828
Step-by-step explanation:
We assume the numbers in the problem statement here mean the cost of living index is $58,000 in Illinois and $70,000 in California. That means the costs in California are 70/58 = 35/29 times those in Illinois.
In order to maintain the same relative lifestyle, you would need to earn (35/29) times $62,000 in California, or ...
(35/29)×$62,000 ≈ $74,828 . . . . acceptable CA salary

Where's the expression?
Step-by-step explanation:
Hi! ❤️ , im looking for some help here. ill give brainliest if able to.
Answer:
A. 2^11
Step-by-step explanation:
The exponent rule you want to use here is that, when multiplying numbers with the same base, you add their exponents and keep the base. Here, you're explicitly being told to multiply 2^4 and 2^7, meaning you should add 4 and 7 and make the sum the power you're raising 2 to. 4 + 7 is 11, so the answer is A. 2^11
B is wrong because you do not multiply the exponents.
C is wrong because there is no multiplication involved at all... strange.
D is wrong because you do NOT multiply the base. Keep it!

A)278
B)-112
C)-72
D)128
Answer:
D) 128
Step-by-step explanation:
Because we will be replacing the variables with numbers we have to that we will have to do the exponent first because of PEMDAS.

A paint mixture is made up of 3/20 red paint and 9/20 blue paint, and the rest is white paint. What fraction of the mixture is white paint?
The paint is sold in 5-litre containers. How many litres of red paint are needed for each container?
How many litres of blue paint are needed for each container?
Answer:
2/5
3/4
2 1/4
Step-by-step explanation:
red paint: 3/20
blue paint: 9/20
white paint: x
What fraction of the mixture is white paint?
x + 3/20 + 9/20 = 1
x + 12/20 = 20/20
x = 8/20 = 2/5
2/5 of the paint mixture is white paint.
The paint is sold in 5-litre containers. How many litres of red paint are needed for each container?
3/20 × 5 litre = 3/4 litre
Each container needs 3/4 liter of red paint.
How many litres of blue paint are needed for each container?
9/20 × 5 litres = 9/4 litres = 2 1/4 litres
Each container needs 2 1/4 liter of blue paint.

The mean amount of money spent on lunch per week for a sample of 75 students is $42. If the margin of error for the population mean with a 99% confidence
interval is 2.10, construct a 99% confidence interval for the mean amount of money spent on lunch per week for all students.
===================================================
Explanation:
The confidence interval is centered at the mean of 42. We add and subtract the margin of error (MoE) from this center to get the left and right endpoints of the confidence interval.
left endpoint = mean - MoE = 42 - 2.10 = 39.90right endpoint = mean + MoE = 42 + 2.10 = 44.10The 99% confidence interval is (39.90, 44.10)
This is the same as writing [tex]39.90 < \mu < 44.10[/tex]
We are 99% confident the mean mu is somewhere between 39.90 and 44.10, excluding both endpoints.
