Answer:
B, C, and F
Step-by-step explanation:
y = 1/2x
y = 1/2(4)
y = 2
y = 1/2x
y = 1/2(-2)
y = -1
y = 1/2x
y = 1/2(2)
y = 1
Answer:
y=0
Step-by-step explanation:
If x equals 28 then substitute it in the equation, 28+3y=28
Next, subtract 28 from both sides, 3y=0
Now that you have that its simple, y must equal 0
Answer:
6-(-67) = 73
Step-by-step explanation:
If k equals -67 the answer would be 73.
Answer:
Step-by-step explanation:
by inspection
angles 2 and 3 are equal, so they will be half angle ABC
angles 1 and 5 are equal so they will be
angle 1 + angle 5 + angleABC = 180° kind of a rule for triangle
the sum of all angles - 180°
(angle 1) x 2 = 180° - 70°
angle 1 = 90° - 35°
angle 1 = 55° which equals angle 5
angle 4 is clearly a right angle 90°
DO the same procedure for the bottom triangle
angle 8 and 9 are half of angle ADC
angle 8 and 9 are half of 46°
both are 23°
angle 6 equals angle 7
2 ×angle 6 = 180° - 46°
angle 6 = 90° - 23°
angle 6 = 67° angle 7 = 67°
Did I find them all
Answer:
2√10 km
Step-by-step explanation:
By Pythagoras theorem,
x^2 + 9^2 = 11^2
x^2 + 81 = 121
x^2 = 121 - 81
x^2 = 40
= 4 x 10
x^2 = 2^2 x 10
x = 2√10 km
