The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
There are 360 degrees. So add the 2 angles you have: 95+45=140. Subtract that from the number of degrees: 360-140=220. X=220 :)
Answer:
78.5°
Step-by-step explanation:
We solve for the above question, using the formula for the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = The distance between the house and the base of the ladder = 4 feet
Hypotenuse = Length of the Ladder = 20 feet
Hence,
cos θ = 4/20
θ = arc cos(4/20)
θ = 78.463040967°
Approximately = 78.5°
Therefore, the angle that the ladder makes with the ground is 78.5°
Answer:
-46/60
Step-by-step explanation:
find a common denominator. multiply that number you got that common denominator with for the numerator (top number) and there is your answer
8.2 x 6.7 = 54.94
= 54.94 divided by 0.46
= about 119.4347...
