Answer:
angle 4 is also 75 degrees
Step-by-step explanation:
3r - 8 = 7 + 8r (make rs on 1 side, numbers on other)
5r = -15(divide by 5 now)
r = -3 (<---Answer)
Hope this helped!
3x + 6y = 18 -6y
3x = 18 - 6y Divide by 3
3x/3=18/3-6y/3 Simplify
x=6-2y
Now we check by plugging in the value of x.
3(6-2y)+6y=18 simplify
18-6y+6y=18 simplify more
18=18.
NOW we know for sure that this is correct
x=6-2y
Based on the distance formula, the distance between points (3, 7) and (x1, y) is:
. SO, it is TRUE.
<h3>What is the Distance Formula?</h3>
The distance formula which can be applied to find the distance between two coordinate points is:
.
Given the points:
(x1, y1)
(3, 7) = (x2, y2)
Substitute

Therefore, the statement that says the distance between points (3, 7) and (x1, y) =
, is TRUE.
