B. 3/4

Step-by-step explanation:

Trey's car has a 20-gallon fuel tank so 1/4 of 20 is 5 so you add the 10 and the 5 so you get 15. so 15/20 simplified is 3/4 which is answer choice B.

Answer:

If 1/4 of the gas tank is filled, then there are 5 gallons currently in the gas tank.

If 10 gallons are added to the gas tank, there will be 15 gallons in the gas tank, meaning that the gas tank will be 3/4 full.

Let me know if this helps!

What is the slope and y-intercept of the line 3x - 4y = 12?*

Lorico [155]

Answer:

m = 3/4; b = -3

Step-by-step explanation:

1) First, put the given equation into slope-intercept form. This is so we can identify its slope and y-intercept easily. Isolate y:

$3x-4y = 12\\-4y = -3x+12\\y = \frac{3}{4} x-3$

2) Lines that are in slope-intercept form are represented by the formula $y = mx + b$ . The number in place of $m$ , or the coefficient of the x-term, represents the slope. The number in place of $b$ represents the y-intercept. So, the slope of $y = \frac{3}{4} x-3$ is $\frac{3}{4}$ , and its y-intercept is -3.
