How do I solve this equation (5x+9) + (3x-2)

1 answer:

8 0

Okie, so you have 2 polynomials separated by a plus sign. If there were a number in front of the polynomial, you would need to factor, as well as if there was a negative sign. But there is just an addition sign so you just add as you would normally.
5x + 9 + 3x - 2 = 8x +7
I hope this helps :-)

The system of equations below represents p, the number of photo files, and v, the number of video files Helena uploaded to an on

ss7ja [257]

P + v = 650....p = 650 - v
4p + 9v = 2925

4(650 - v) + 9v = 2925
2600 - 4v + 9v = 2925
-4v + 9v = 2925 - 2600
5v = 325
v = 325/5
v = 65.....video files

p + v = 650
p + 65 = 650
p = 650 - 65
p = 585....photo files

answer : Helena uploaded 9 times as many photo files as video files
65 * 9 = 585

Rewrite this non-statistical question as a statistical question. How many minutes do I exercise each day?

stira [4]

Answer:

The statistical question should be

"how many minutes do I exercise on each day of the week" and "how many minutes do I exercise each day of the week whilst there is background music"

Step-by-step explanation:

Here we have the non statistical question, how many minutes do I exercise each day

We note that a statistical question is one in which there are are different variety answers, where the distribution and the inclination of the the answers is sought

Therefore, statistically, we should ask, "how many minutes do I exercise on each day of the week" or "how many minutes do I exercise each day of the week whilst there is background music".

-4

Step-by-step explanation:

-4z² + z²

let's assume you have z² and you're owing 4z², you'll pay the z² you have and you'll still owe 4

so that is -4
