The answer is 1-y I just did this quiz in k12 I did it today at first I didn't get it but then I do know
are you In k12 9th grade?
Answer:
Intercept = - 3 ; slope = 18
Step-by-step explanation:
Given the points :
(3, 51) ; (5, 87)
x1 =3, y1 = 51, x2 = 5 ; y2 = 87
Slope intercept relation:
y = mx + c
m = slope ; c = intercept ; x and y are x, y vlayes respectively
Slope (m) = (y2 - y1) / (x2 - x1)
Slope (m) = (87 - 51) / (5 - 3)
Slope = 36 / 2
Slope (m) = 18
The intercept c :
m = 18 ; x = 5 ; y = 87
Substitute values into the slope intercept formula :
87 = 18(5) + c
87 = 90 + c
c = 87 - 90
c = - 3
Intercept = - 3
Answer:
y ≤ -4x+25
Step-by-step explanation:
First we need to figure out the equation for the line
The y intercept is 25
Next figure out the slope
slope = (y2-y1)/((x2-x1)
= (49-25)/(-6-0)
= 24/-6
= -4
The equation for a line in slope intercept form is y = mx+b
y = -4x+25
This is a solid line so our inequality will have an equals in it.
It is shaded below, so y is less than.
If it was shaded above, y would be greater than
y ≤ -4x+25
Please note that in the original problem you have horizontal division symbols:
4 1 3
--- x - ---- = -----
5 10 10
On the other hand, you have typed <span>4/5x-1/10=3/10. To avoid ambiguity you must enclose the fractions inside parentheses:
</span><span>(4/5)x- (1/10) = (3/10). Otherwise, your reader will not know for sure whether you meant 4 / (5x) or (4/5)x.
</span><span>After you've typed in these parentheses, your next task is to mult. all the terms of this equation by 10, to remove the fractions. Result:
8x - 1 = 3, or 8x = 4, or x = 1/2 (answer)</span>
Th equation that can be used to determine when they would have saved the same amount is 0.3(10 + 4h) = 0.25(6h).
<h3>When would they have saved the same amount?
</h3>
The equation that can be used to determine the amount saved by Fernando is:
total amount saved = percentage saved x (amount charged to drive to the appointment + total amount earned)
0.3( $10 + $4h)
The equation that can be used to determine the amount saved by Brenna is:
percentage saved x total amount earned
0.25h
When they save the amount amount, the two above equations would be equal: 0.3(10 + 4h) = 0.25(6h).
