A line passes through the point (8, -3) and has a slope of 3/4 write an equation in slope intercept form
erik [133]

Answer:

y = (3/4)x - 9

Step-by-step explanation:

The slope-intercept form of the equation of a straight line is y = mx + b.

Here we know x, y and m, but must find b.

Substituting 8 for x, -3 for y and 3/4 for m in the equation above results in:

-3 = (3/4)(8) + b, or (after multiplying all three terms by 4 to clear fractions):

-3 = 6 + b

Then b = -9, and the desired equation is     y = (3/4)x - 9

What is the area of this octagon
Juliette [100K]

Answer:

59cm^2

Step-by-step explanation:

first you can do 8x9 to get 72 then you can subtract 4x2 from 72 to get 64 and lastly you have to subtract 4 from 9 to get the area of the small rectangle on the left so you get 5 and then you have to get the width which is 4+3 from the top and subtract that from 8 on the bottom which is 1 so now you have 5x1 which is 5 and subtract that from 64 to get 59cm^2

hope this helps

Write the fractions as fractions with a common denominator 3/4 and 1/3
JulijaS [17]

3/4 and 1/3

4x3 = 12 that will be the common denominator.

For 3/4 we first divide 12/4 = 3 and then multiply 3 x3 = 9 that's the numerator

For 1/3 we first divide 12/3 = 4 and then multiply 1x4 = 4 that's the numerator

The fractions will be rewrited as: 9/12 and 4/12
