Answer:
4/5
Step-by-step explanation:
You can remove the trailing 0s, and you have 0.8
this is equal to 8/10
8 and 10 can be divided by 2
8÷2=4
10÷2=5
thus, you get 4/5
Answer: Graphing a Quadratic Function
y=−10x2−31x
Step-by-step explanation:
Graphing a Quadratic Function
f(x) ÷ x - k.
9) f(x) = x' - 8x? - 10x² – 24x
Answer:
The equations are:
10x + 9y = 122
x + y = 13
Step-by-step explanation:
Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.
Also, it is given that he had worked for 13 hours total making 122$.
Let us assume the number of hours he spent on washing cars = 'x'.
Let us assume the number of hours he spent on walking dogs = 'y'.
Since, the total number of hours is 13, we can write:
x + y = 13 . . . eqn(1)
And since he has made 122$ in total, we will have:
10x + 9y = 122 . . .eqn(2)
'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.
Hence, Eqn (1) and Eqn(2) is the answer.
Solving them will give: x = 5 and b = 8.
