Answer:
Perpendicular
Step-by-step explanation:
2x - y = -7
2x + 4y = 2
-y = -2x - 7
4y = -2x + 2
y = 2x + 7
y = -1/2x + 1/2
Cannot be:
Parallel because the slope would otherwise be the same.
Same line because the equation is not proportional
So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
Answer:
There are 12 apples in total.
Step-by-step explanation:
If Anne gave Ben 6 apples then heres how:
2:3 subrtact 6 apples = 1:3
6 apples x 2 = 12 apples =
2 ÷ 2 = 1
Hence, your answer is double 6 which is 12 apples.
Hope this helps :)
The sin of any given angle is:
sin(∅) = perpendicular / hypotenuse
The perpendicular of angle A will be equivalent to the base of angle B. Therefore,
Cos(B) = 243/312
B = Cos⁻¹(243/312)
B = 38.8°
The measure of angle B is 38.8 degrees.
