B. neither is a solution because 24-7 and 24-3 don’t come out to 20.
Answer:
27
Step-by-step explanation:
I divided im not 100 percent sure tho
-2x + xy = 30.....when y = 8
-2x + 8x = 30
6x = 30
x = 30/6
x = 5 <==
This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
Answer:
y=4x+1
Step-by-step explanation:
to find the slope (m) you have to calculate what rise over run is for you table, in this table rise (y values) go up by 4 every time. so thats the numerator for your slope. the run is how much the x value goes up everytime, it goes up by 1 so the denomenator is 1, this simplifies to 4 so m= 4. the y intercept (b) is the y point where x equals zero so it is 1. x and y are simply variables used when graphing so they have no set values.
