First subtract 3 from 51 which gives you 48, then divide 48 by 3 which gives you the answer of 16.
<u>Answer:</u>
The right graph is the first one (figure attached).
Note that in a Speed vs Time graph, the constant speed is represented by a line with slope=0 <u>(for example, segment 1)</u>, when the speed increases the slope is positive <u>(for example, segment 2)</u> and when the speed decreases the slope is negative <u>(for example, segment 4).</u>
Now, if we want to prove this, let’s read again the problem, <u>dividing each section of the path Marc drove to his work</u> (see figure attached):
1. He slowly pulls out of his driveway at a <u>constant speed
</u>
2. and then his <u>speed increases</u> steadily
3. until he reaches the speed limit. He uses cruise control to drive the speed limit <u>(he drives at constant speed)</u>
4. until he comes upon some traffic
(usually if you find some traffic you have to <u>derease your spped</u>)
5. He then slows down to a new <u>constant speed</u>.
6. When he gets near his office, his <u>speed steadily decreases</u> until he comes to a stop right in front of his office building <u>(at this point the speed is zero)</u>
Felix starts off with 11, so that's our constant.
Each week he saves $5 which is our slope.
Equation for Felix:
Y=5x+11
Eddy has $60 which is our constant
He saves $2 which is our slope
Equation for Eddy:
Y=2x+60
Slope = ⅓
y-intercept = 0
x-intercept = 0
Answer:
-7 and -10 are solutions, 5 and 0 aren't
Step-by-step explanation:
For the inequality, -4 + 5y will have to be less than or equal to -39. So, y would have to be a negative number. That would remove 5 as a possible solution.
Next, we can calculate the solution for others. For 0, we can multiply it by 5 and get 0. Then, add it to -4 which would get us -4. This is greater than -39 so 0 isn't a solution.
If we solve for -7, we'll get: -4 + 5(-7) -> -4 - 35 -> -39. This is equal to -39 so it is a solution. If we solve for -10, we get: -4 + 5(-10) -> -4 - 50 -> -54. This is less than -39 so it is a solution.
