Answer:
The answer should be "B" (The area of △RST is equal to the area of △LMN.)
Put all number choices in for x.
1+5=6,
3+5=8,
5+5=10,
7+5=12.
The equation says that the answer has to be greater than ten. 6 and 8 are less than ten, and ten is equal to ten, so the only answer is 7, because 7+5=12 :)
Answer:
the answer is actualy 12

Answer:
y = -3x +5
Step-by-step explanation:
The parallel line will have the same slope: m = -3.
The new y-intercept is ...
b = y -mx
y = -1 -(-3)(2) = -1 +6 = 5
Then the equation of the parallel line through (2, -1) is ...
y = -3x +5

Answer:
30°
Step-by-step explanation:
The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:
Sin = Opposite/Hypotenuse
For a ramp 1 m high and 2 m long, we have ...
sin(x) = (1 m)/(2 m) = 1/2
x = arcsin(1/2) = 30°
The elevation angle of the ramp needs to be 30°.
