Step-by-step explanation:
x + y = 9. => 2x + 2y = 18.
2x + 2y = 18
- (2x - 3y = -12)
=> 5y = 30, y = 6.
Therefore x + (6) = 9, x = 3.
The solution is x = 3 and y = 6.
Answer:
20 fries per minute.
Step-by-step explanation:
If you express the number of fries per minute as 100/5 (as there are 5 minutes and 100 fries), assuming she ate at the same rate per minute, she had 20 fries per minute.
To check, multiply 20 by 5, in order to find out her fries per 5 minutes. It should be equal to 100.
6y+1>=10
Subtract 1 from both sides
6y>=9
Divide 6 on both sides so that the only thing remaing on the left side is the variable y.
Final Answer: y>= 1.5 or 1 1/2
Answer:
2x+13
Step-by-step explanation:
Plug in (x+3) in the F(x) function so:
f(x+3) = 2(x+3) + 7 = 2x+6+7 =2x+13
ANSWER: F(x+3) = 2x+13
<h3>
Answer: x = -3</h3>
The two diagonal lines cross at (-3,5). We only need to worry about the x coordinate here, so x = -3 is what we're after. If x = -3, then f(x) and g(x) have the same y output meaning f(x) = g(x). That y output is y = 5.
