836, because 484 divided by 22 is 22, so each gallon can do 22 miles. 38 times 22 is 836.
Answer:
0
Step-by-step explanation:
y = 1/2x + c
Put x as 1, and y as 1/2.
1/2 = 1/2(1) + c
1/2 - 1/2 = c
0 = c
Answer:
D: x = -18
Step-by-step explanation:
A good way to solve this it to input all options until you find the one that fits for both options.
Option A :
15 + 6 / 15 - 3 = 21 / 12 or 7/4
So this one doesn't work.
Option B :
10 + 6 / 10 - 3 = 16 / 7
So this one also doesn't work.
Option C:
3 + 6 / 3 - 3 = 9 / 0 which is 0 by the laws of dividing by zero.
This one also doesn't work leaving only one option.
Option D:
-18 + 6 / -18 - 3 = -12 / -21 or 4 / 7
And by solving we can find out we did our work correctly and get our answer.
Answer:
-3.5, -4/5, .25, 1/2, 2.5
Step-by-step explanation:
2x + y = -1
y = -2x - 1....the slope here is -2.
A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(0,-2)....x = 0 and y = -2
now we sub and solve for b, the y int
-2 = -2(0) + b
-2 = b
so ur parallel equation is : y = -2x - 2 <==
=================
so our original equation has a slope of -2
A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, we " flip " the slope and change the sign....-2 (or -2/1).....flip the slope and it becomes -1/2.....change the sign...and it becomes 1/2. So our perpendicular line will have a slope of 1/2.
y = mx + b
slope(m) = 1/2
(0,-2)...x = 0 and y = -2
now we sub and find b, the y int
-2 = 1/2(0) + b
-2 = b
so ur perpendicular equation is y = 1/2x - 2 <==
