<em><u>Complete Question:</u></em>
What is the y intercept of y = -3-7x
<em><u>Answer:</u></em>
<h3>The y intercept is (0, -3)</h3>
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
y = -3 - 7x
The y intercept is the point where the line crosses the y axis
<u>Finding y intercept:
</u>
To determine the y-intercept, we set x equal to zero and solve for y
Substitute x = 0 in given equation
y = -3 - 7(0)
y = -3 - 0
y = -3
Thus the y intercept is (0, -3)
Answer:
56.45
Step-by-step explanation:
Coefficient skewness=(Third quartile+ first quartile)-n*Median/Third quartile-first quartile
Third quartile is the unknown?
First quartile is 30.8
n is the number of steps taken from first quartile to reach third quartile which is 2 steps.
coefficient skewness is -0.38
let p represent third quartile
-0.38=(p+30.8)-2(48.5)/p-30.8
by cross multiplication
-0.38(p-30.8)=(p+30.8)-97
-0.38p+ 11.704 =p+30.8-97
-0.38p-p=30.8-97-11.704
-1.38p=-77.904
p=-77.904
/-1.38= 56.45
.415 or 41 cents per can
you would divide 4.98/12 because the total cost is $4.98, and ian is buying 12 cans, so if they are all equal in price then you divide 4.98/12 to get your final answer of 41 cents each
Two things must be performed to make an equation that satisfies this. First, we need to come up with a general equation that is perpendicular to the one in the problem. To do this, the reciprocal of the slope is calculated (negative inverse). The line that is perpendicular to y=1/8x + 2 has a slope of -8. This is what our equation looks like so far:
y’=-8x
This is good, but it doesn’t pass through (1,5). To make it do this, put the point in the equation and solve it - a point on a graph that intersects the line is a “solution” of the equation, so we need to solve for it!
y’ = -8x
(5) = -8(1)
Nope, 5 doesn’t equal -8. Let’s make the two sides equal by adding 13 to the right side.
y’ = -8x + 13
(5) = -8(1) + 13
5=5 - yes!
Our equation that is perpendicular to the one in the question and also passes through the point (1, 5) is y’=-8x + 13.
Hope this helps!
