Another way to say f(x) is y, so y=0 at -2 and 10. :)
Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5
2y+10=22
2y=12
y=6
1.5+6=7.5=7½
Answer:
The ratio is 6:2:1.
Step-by-step explanation:
Let's denote:
Blue counter b
Red counter r
Yellow counter y.
There is given
r=3b (three times more red as blue) [1]
and
b=2y (twice more blue as yellow.) [2]
Now, replacing [2] to [1] gives
3*2y=r
6y=r.
Hence, the ratio is 6:2:1, because r=6y and b=2y.
Answer:
10x+40
Step-by-step explanation:
To solve you must follow these steps:
1. Multiply the outside (5) by the first number on the inside (2x) and you get 10x
2. Multiply the outside (5) by the second number on the inside of the parenthesis (8) and you get 40
3. You are left with 10x and 40, so your answer is 10x+40
Hope this makes sense, have a wonderful day!
