Answer:
2/3x + 7 = 29
step-by-step explanation:
two thirds = 2/3
plus a number = x
at least 29 = 29
there for you should get 2/3x + 7 = 29
It would be 13 + 10t because she starts with 13 dollar charge in the first hour but every hour after that would be 10 dollars an hour.
I plugged it into my calculator and I got 1,870.
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
Answer:
The amount driven would be 275, and the cost for both plans will be 77.75$
Step-by-step explanation:
make both equations
y=0.09x+53
y=0.13x+42
set them equal to each other and solve for x to get the distance
take that number and put it in one equation and solve for y to get the price of the plan for that value
