Answer:
-6
Step-by-step explanation:
Multiply the second equation by 2 and add 6x. You get ...
-6x +y = -6
y = 6x -6
This is the same as the first equation when b = -6. That is what you want if you want infinite solutions.
Answer:
64 m, at time t = 4 sec
Step-by-step explanation:
We must maximize the function h = 32t – 4t^2. One way in which to do this is to find the axis of symmetry, t = -b / [2a], and from that calculate the height:
a = -4, b = 32, c = 0
-32
and therefore the axis of symmetry is t = ---------------- = 4
2(-4)
The height, h, at time t = 4, is h(4) = 32(4) - 4(4)^2 = 64 m
The maximum height of the ball is 64 m, at time t = 4 sec
Bruh just guess school suck
Answer:
An additional student came by to inform me that they lost their phone yesterday (he thinks by the bus station). It is an iPhone 13 in a black case. If anyone has come across it, please bring the device to Mr. Velez in room 112 and on behalf of the student, thank you!

The total number of miles is 5.6 so 5.6 miles divided by 3 hours is 1.86recurring miles per hour rounded up to 1.87 miles if you do it to three significant figures.
hope this helps. if any of it doesn't make sense don't hesitate to ask me about it :)
