(5,2) and (-1,-6)

Slope = (2 + 6)/(5 + 1) = 8/6 = 4/3

Point-slope equation form:

y - 2 = 4/3(x - 5)

Hope that helps.

6 9/10 x 20/21<br> Simplify your answer completely and change to a mixed number.
Sidana [21]

Answer:

6\frac{4}{7}

Step-by-step explanation:

Hello,

I am going to start with to change to a improper fraction:

1. I will convert 6 and 9/10 into a improper fraction:

69/10

2. Now that I have converted the mixed fraction into a improper I can multiply the numerator and the denominator.

69 * 20 / 21 * 10 = 1380/210

3. Now I can simplify this value and convert it into a mixed fraction

46/7

After further simplifying I can convert this into an mixed number

6\frac{4}{7}

Persons taking a​ 30-hour review course to prepare for a standardized exam average a score of 620 on that exam. Persons taking a
mihalych1998 [28]

Answer:

y = 4.125x + 496.25

Step-by-step explanation:

Set the data up as points. Then deal with the points.

Givens

(30,620)

(70,785)

y2 = 785

y1 = 620

x2 = 70

x1 = 30

Formula

Slope = (y2 - y1) / (x2 - x1)

Solution

Slope = (785 - 620)/(70 - 30)

Slope = 165 / 40

Slope = 4.125

===================

Now you need the y intercept. Either one of the two given points will give you that.

y = 620

x = 30

m = 4.125

y = mx + b

620 = 4.125*30 + b

620 = 123.75 + b

620 - 123.75 + b

b = 496.25

Write an equation where the variable is divided by a number, and a solution is -4/5
MrMuchimi

Answer:

x/-5

Step-by-step explanation:

Just divide by 5 and the denominator will be 5 meaning x would have to be 4.

Make sure your 5 is negative so the whole equation also ends up negative. x/-5=-4/5

Whats the awenser for (9m - 6)7
svet-max [94.6K]
(9m - 6)7
Distribute 7 to both sides
63m - 42
Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3
