Answer:
D y-8 +2 ≤ -2+2
Step-by-step explanation:
y-8 ≤ -2
Add 2 to each side
y-8 +2 ≤ -2+2
Answer:
The correct answer is option C.
Step-by-step explanation:
Let the number be x.
The square of a number exceeds that number by 12 .Mathematically can be written as:
Using middle term splitting to factorize the expression:
The two possible solutions are :
1) (x+3)=0
x = -3
2) (x-4)=0
x = 4
Answer:b
Step-by-step explanation:
Answer:
4/5
Step-by-step explanation:
In a right triangle, the longest side is always the hypotenuse. Hence
Hypotenuse =5cm
The side opposite to the angle theta is the opposite, hence
Opposite = 4cm
Required
Sin theta
According to SOH CAH TOA
Sin theta = opposite/hypotenuse
Sin theta = 4/5
Hence the sine of the angle opposite the side of length 4cm is 4/5
D because 3/4 is .75 so 7.75 divided by .75 equals 10.333333333333333
