Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
4y = 12x + 16
3x = y - 4
=>
y = 3x + 4
using that in the first equation
4(3x+4) = 12x + 16
12x + 16 = 12x + 16
=> both lines/equations are identical, so they have infinitely many solutions.
The square root of 78 is an irrational number, so the exact number
can't be written down, no matter how long you make the decimal.
If I say it's 8.8318, then my answer is too big, but only by about 0.0004 percent.
This is how I did it:
use distribution
use addition
use addition and subtraction
use division
So your answer is
<span>1)
y = 47.3 + 0.78x. for x=17
put 17 in function
y=47.3+13.26=60.56
2) rise/run =rate of change=3/36=1
1/12 inches.

4) 16 birdhose
he akes 2 birdhouse in 30 minute
so 4 --------in 1 hr(60 min)
16 ------------in 4 hr
