Answer 1

Answer:

Answer:

Step-by-step explanation:

156% = 1.56 while 70 = 100%

if 100% = 1 it would look like this

of is used as a division word so the first 1 is 156/100

70 is the 100% so 70 is the denominator for the second problem and your trying to find out what the n is.

n is your problem 156% of 70 = n

have a nice day and mark me brainliest :)

What Is The Slope-Intercept Form Of This Equation 3x+9y=18

Answers

Y= -1/3x+2 because The Change in x and the change in y come out to -1/3x then you plug in the coordinates and solve for b. Hope i helped

Answer:

Solve the given equation for y to obtain the slope and y-intercept of this equation: -3x + 9y = 18

Add 3x to both sides: 3x - 3x + 9y = 18 + 3x

Simplifying, 9y = 3x + 18

Dividing both sides by 9 to solve for y:

y = (3/9)x + 2 or (after reduction) y = (1/3)x + 2

The slope is 1/3 and the y-int. is (0,2).
