Answer:
G) y=3x+1
Step-by-step explanation:
1 would equal b = y-intercept
-3 is the slope = m
y-intercept form is y=mx+b
plug it in
y=-3x+1
Answer:
Nothing
Step-by-step explanation
This expression is not solvable. This expression is incomplete. You need something on the other side of the equal sign to solve this equation. For example: 3x+2y=10 now this is a solvable expression. I hope this helped you in some way!
Well you multiply...
3x3.69 is 11.07
15x4 equals 60
add 11.07 and 60, which you should get 71.07
she has had a budget of spending $71.07
Answer:
7:6 and 49:36
Step-by-step explanation:
The Pyth. Thm. tells us the following: (hypo)^2 = (leg 1)^2 + (leg 2)^2.
Here the hypo is 75 miles. One train traveled x miles and the other x+10 miles.
applying the Pyth. Thm.,
x^2 + (x+10)^2 = 75^2
which becomes x^2 + x^2 + 20x + 400 = 5625, or
2x^2 + 20x - 5225 = 0.
Choose a method easy for you that will lead to a solution (x-value).
Using "completing the square," I obtained x= 47.8 miles and x = 57.8 miles. I
It's very important to check one's work. Suppose x = 47.8 miles. Then x+10 = 57.8 miles.
47.8^2 + 57.8^2 = 75^ must be true. Is it?
2284.84 + 3340.84 5625
5625.6 is approx equal to 5625. Close enough.
The first train traveled 47.8 miles and the second 57.8 miles.
