Answer:
10°
Step-by-step explanation:
Complementary angles where either of two angles whose sum is 90°
B= 50°
90°-50°=40°
40/4=10
So the answer is 10°
Answer:
b = 6.928
Step-by-step explanation:
Looks like a job for the Pythagorean Theorem.
a^2 + b^2 = c^2
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b = 6.928
Hope it helps!!
Step-by-step explanation:
8x + 14y = 4 ...1
-6x - 7y = -10 ...2
...2 × 2 in 2 sides of the equation
-12x -14y = -20 ...3
...1 + ...3
8x + 14y +(-12x -14y) = 4 +(-20)
8x + 14y - 12x -14y = 4 - 20
-4x = -16
x = (-16)/(-4)
= 4
replace x in ...1 or ...2 you will reserve y value
and answer in the term of (x,y)
Answer:
Step-by-step explanation:
y is always (1/3) of x.
Thus, if x = 0, y = 0; if x = 1, y = (1/3)(1) = 1/3, and so on. The corresponding ordered pairs are (0, 0), (1, 1/3), (-2, -2/3)
The slope formula is is rise over run or y2-y1/x2-x1
If you plug in those numbers you will get
(-1)-(-4)
———
1-(-2)
Simplify it and you get
3
— or 1
3
So the slope is 1
