Perpendicular = opposite sign and reciprocal slope
Make equation y= mx + b
3x + 4y = 24
4y = -3x + 24
y = -3/4x + 6
Now make slope perpendicular
Slope = 4/3
The answer would be B.

Answer:

4/3 (answer choice b)

Step-by-step explanation:

first, you convert the equation to slope intercept form as well as make sure y doesn't have a coefficient by dividing the whole equation by 4. (y=-3/4x+6) Next, you find the reciprocal of the slope which in this case is -4/3 ,and divide it by -1 giving you 4/3.

What does 4 5/8 - 1 2/5 equal?

mihalych1998 [28]

$4 \frac{5}{8} - 1 \frac{2}{5} \\ \\ \frac{37}{8} - \frac{7}{5} \\ \\ \frac{185}{40} - \frac{56}{40} = \frac{185 - 56}{40} \\ \\ = \frac{129}{40} = 3.225 = 3 \frac{9}{40}$

I hope I helped you^_^

Isabel received 4/7 of the 210 votes for cast for class treasurer. How many votes did she receive? Write your answer in simplest

KengaRu [80]

Answer:

120 votes

Step-by-step explanation:

So one way to solve this is by creating an equation to solve for x.

So we are given 4/7, that will be one side of the equation.

And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.

So 4/7 = x/210

We want to get x alone, so we can multiply 4/7 by 210, which equals 120.

So x equals 120!
