Times 3 6 times but not 3 times 6
Answer:
A
Step-by-step explanation:
3x+4(3x+6)= 15x+24
distribute 4(3x+6)
which equals 12x+24
3x+12x+24= 15x+24
Now combine like terms
15x+24= 15x+24
its equal so BOOM .

Answer:
62 week
Step-by-step explanation:
What we need is to represent the ratios in expression
For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is
992-5x
x is the weeks
And the other case the expressions is
1240-9x
The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount
992-5x=y
1240-9x=y
in both the y is the same, then
992-5x=1240-9x
992-1240=-9x+5x
-248=-4x
-248/-4=x
62=X
and that is the weeks we need for the amount being the same in both tanks
The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.
0 = 5x - 45
+ 45 + 45
45 = 5x
/5 /5
9 = x
And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:
y-intercept = -45
x-intercept = 9
Hope that helped =)
