Standard form is presented as Ax + By = C
all you need to do here is move the y value over to the side with the x value.
so,
x + 2/7y = 3/4
Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
Answer:
the ratio is 1:5 or 20%
Step-by-step explanation:
3(steak)+2(chicken) + 5(potato) = 10(all tacos)
2(chicken tacos)/10(all tacos) = 1/5 or 0.2
<span>3x + (x-8) = 23
Combine like terms first. You can combine 3x and x because they have the same variable.
4x - 8 = 23
Now add 8 to both sides.
4x = 31
Last step is to divide both sides by 4 to isolate the x.
4/4x = 31/4
x = 7.75 is the answer.</span>
