Answer:
y = -4/7x + 36/7
Step-by-step explanation:
First find the slope between the points,…
Answer: -4/7
Then use a point and the slope together to find the y-intercept
Answer: y = -4/7x + 36/7
Explanation:
The slope-intercept of a slope only would be like:
y = mx
Then write the slope-intercept form of a slope only:
y = -4/7x
Then use a point (-5, 8) to find the y-intercept
y = -4/7x + y-intercept
(8) = -4/7(-5) + y-intercept
8 = 20/7 + y-intercept
y-intercept = 20/7 - 8
y-intercept = -36/7
The answer would be c as you would want R to be by itself so you would divide both sides by 3
Answer:
182:242
Step-by-step explanation:
Reduce the ratio by its halves (50 percent) and simplify.
Although for this case, you could reduce it even further, because this is a ratio, not the true height.
If this is a test, I would not recommend that.
Answer:
Option A: −5+i
Step-by-step explanation:
In the complex plane, the real part of the number is expressed in the horizontal axis, and the imaginary part is expressed in the vertical axis. So, to find the distance of a point to the origin, we just need to apply the distance formula with the second point being (0,0):
A. −5+i
real part: -5
imaginary part: 1
distance to origin: D = sqrt((-5)^2 + 1^2) = 5.099
B. −2+4i
real part: -2
imaginary part: 4
distance to origin: D = sqrt((-2)^2 + 4^2) = 4.4721
C. 3 + 3i
real part: 3
imaginary part: 3
distance to origin: D = sqrt(3^2 + 3^2) = 4.2426
D. 4 + 3i
real part: 4
imaginary part: 3
distance to origin: D = sqrt(4^2 + 3^2) = 5
So the farthest point from the origin is point A: −5+i
