Answer: 150

Step-by-step explanation: so when you want a whole amount of something you want to the 100% of it because 100% is the whole thing right? Well right now you only have 20% so how much do you need to multiply that by to get 100%?? Well that answer is 5. Okay so now since $30 is 20% but we wanna get it to 100% multiply it by 5 so 30x5 which is 150

Write an equation that passes through a pair of points

Phoenix [80]

Answer:

C. $y = -x + 2$

Step-by-step explanation:

First, find the slope, m, of the line that passes through the two given points.

Slope = $\frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1$

Next, determine the y-intercept, b.

The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.

Now, to get an equation of the line, substitute m = -1, and b = 2 in $y = mx + b$ .

✅The equation would be:

$y = -1x + 2$

$y = -x + 2$

Please help, I have redone this problem a million times and i cant get it right. Time sensitive!!

Advocard [28]

Answer:

D

Step-by-step explanation:

This should be easy one unless you're making silly mistake like forgetting to take reciprocal of $\frac{3}{2x}$

lets do it:

$\frac{x+2}{x-1}$ ÷ $\frac{3}{2x}$ first: we take the reciprocal of 3/2x now its

$\frac{x+2}{x-1}$ * $\frac{2x}{3}$ now just multiply top and bottom by using distributive method

$\frac{2x^2 +4x}{3x-3}$ this is your answer.
