Answer:
The y intercept is the b in y = mx + b
Step-by-step explanation:
Fiona drives 3 1/2 hours on highway = 3.5 hours
average 60 miles per hour on highway.
Then 3.5 * 60 =210 miles
1 1/2 hours in the city = 1.5 hours
average 30 miles per hour in city
Then 1.5 *30 = 45 miles
So
Fiona drives 210 miles on highway and 45 miles in city.
Total of her trip to her grandmother's house equals:
210 + 45 = 255 miles
She drives 3.5 on highway and 1.5 in the city, then total driving should be:
3.5 + 1.5 = 5 hours
Average speed for the entire trip:
255 /5 = 51 miles
Answer:
To expand a polynomial, multiply its factors (often by using the distributive property) or perform the indicated operations. Then combine all like terms. Example. Expand the following expression. 3x(4 - x) + (2x - 5)2.
how to do it, if you dont know use the steps.

Answer:
![\sqrt[4]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D)
Step-by-step explanation:
We start with the original problem:
So first we start by applying the quotient rule for powers, which tells you that whenever you are dividing two powers that have the same base and different power, you can copy the base and subtract the powers:
so:
which yields:
since we are talking about a rational exponent, we can next turn it into a radical by using the following rule:
![b^{\frac{1}{a}}=\sqrt[a]{b}](https://tex.z-dn.net/?f=b%5E%7B%5Cfrac%7B1%7D%7Ba%7D%7D%3D%5Csqrt%5Ba%5D%7Bb%7D)
so:
![2^{\frac{1}{4}}=\sqrt[4]{2}](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7B2%7D)
Answer: x=2
both 3 and 9 share the same x axis
