Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (-9,-3) and (-2,r) fall on a line with a slope of 1/7. What is the value of r?
If its not right im gonna report you

Answers

Answer 1

Answer:

R = -2

Step-by-step explanation

-9, -3 is the first point.

A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.

-9 - 7 = -2

-3 - 1 = -2 (r)

with a slope of 1/7, (-9, -3) connects to (-2, -2)

The owner of an audio store received a shipment of portable stereos at a cost of $88.90 each. If he sells the stereos for $152.99 each, what is the percent of markup? Round to the nearest whole percent.

Answers

He would get a profit of 64.09
64.09 or 64% because if you subtract 152.99 from 88.90 you get 64.09 and you round it to 64% because the 0 is under 5 so you lower it

Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8

Answers

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

-x+7=-0.5x^10 -4.5^10

am I getting ...!?

Answer:

(-1,6) and (-7,0)

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

times both sides by -2

2x-14=(x-3)^2-16

expand

2x-14=x^2-6x+9-16

add 14-2x to both sides

0=x^2-8x+7

factor

0=(x-7)(x-1)

set to zero

0=x-7

7=x

0=x-1

1=x

so find y

y=-x+7

y=-1+7

y=6

or

y=-7+7

y=0

[tex]y - y_{1} = m( x - x_{1})[/tex]
​

Answers

Explanation:

The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.

to find the mean you add up all of the numbers that you see, then divide that total by the numbers you divided. in this case you would add 3+5+7+10+10+4+7+5+8+10+6. you should get 75. you added 11 numbers together so you would divide 75 by 11 to get 6.8
3+5+7+10+10+4+7+5+8+10+6=75

75/11=6.81

you add all the numbers together then you divide the answer by how many numbers you have
