It would be elimination (C) because 7x and -7x can be eliminated into 0.
7x + 5y = 19
-7x - 2y = -16
3y = 3
3 3
y = 1
7x + 5y = 19
7(1) + 5y = 19
7 + 5y = 19
- 7 - 7
5y = 12
5 5
y = 2.4
(x, y) = (1, 2.4)
Answer:
93,600
Step-by-step explanation:
4x104= 416
416x225 = 93,600
Answer:
Slope intercept form is y=mx+b. M= -1, which means your slope is -1. So far the equation is y=-x+b. Now you need to find b which is the y-intercept. To find b, you will use the point (1,3). You will plug it in into the equation, it will look like this 3=-1(1)+b. Now you solve for b. Multiply -1 and 1 you get -1. Add 1 to both sides and you have b=4. So the equation is y=-x+4. So to find k, plug in the point (k,6). It will look like this 6=-k+4. Subtract 4 on both sides. 2=-k is what you have so far. Divide by -1 on both sides. THE ANSWER IS K=-2.
Answer:
Melissa needs to drive 325 miles for the two plans to cost the same
Step-by-step explanation:
<u>Plan A</u>
Initial Fee = 65
Additional cost per mile = 0.50 per mile
<u>Plan B</u>
Initial Fee = 0
Additional cost per mile = 0.70 per mile
Required
Mile both plans will cost the same
Let
So, we have:
For plan A
For plan B
So, we have:
--- plan A
--- plan B
Both plans will cost the same when
Divide by 0.20
