Answer:
Alternatively you can write it as;
Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is
or you can further simplify it to:
And you can then solve for x to be 9 hours.
Answer:
a) 24
b) -21.
Step-by-step explanation:
For question a), we first solve whatever is in the parenthesis, because of PEMDAS.
Our original equation was:
4 (6 + (-3)) + 3 (4)
We get rid of the parenthesis first. 6 + (-3) = 6 - 3 = 3, so we have:
4 (3) + 3 (4)
We can multiply, and then add.
12 + 12 = 24.
For question b), we once again start off with getting rid of the parenthesis. However, within the parenthesis, we still have to follow PEMDAS, meaning that we have to do the multiplication first and the subtraction after.
Thus we have:
-2 (6) + 3(-3)
We can multiply things out and then add.
-12 + -9
= -1 (12 + 9)
= -1 (21)
= -21.
For angle one do 180-74 then divide by two and it will give you the angle for angle one and for angle two you just add the angle given and angle one then subtract by 180
Function f(4) = -10 and if g(x) = 2 , x = 0.
To find f(4), we will observe the graph of f(x).
According to the graph of f(x),
when x = 4, y is -10 which means when x is 4 value of f(4) is -10.
To find the value of x when g(x) is 2, we will observe the graph of g(x).
According to the graph of g(x),
when y = 2, x is 0 which means that when x is 0, the value of g(x) is 2.
Hence, f(4) is -10 and x = 0 when g(x) = 2.
