Step-by-step explanation:
<u><em>The question is</em></u>
Find the value of XY
see the attached figure to better understand the problem
we know that
-----> by segment addition postulate
If X is the midpoint WY
then
substitute in the formula above
substitute the given values and solve for XY
Subtract 6 both sides
Divide by 2 both sides
Rewrite
Answer: y = (1/8)x + 3.625
Step-by-step explanation:
slope: y = mx + b
change from 3 to 4 is 1, this is our rise
change from -5 to 3 is 8, this is our run
1/8 = m
this is a really bad explanation but I know that
1/8 is equal to 0.125.
since there are 5 spaces from (-5,3) to the y axis, and that the slope is 1/8, i can multiply 1/8 x 5 to get 5/8.
5/8 =.625
since the x intercept is in between 3 and 4, it is 3.625.
3.625 = b
Ok so if 4x-y=5 then x+y=10 thats the answer
Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed! So, integers can be negative {−1, −2,−3, −4, ... }, positive {1, 2, 3, 4, ... }, or zero {0}
Is B. A typo? Is it supposed to say -4? If so that’s the answer
