Answer:
All real numbers except -3
Step-by-step explanation:
Range refers to numbers on the y-axis.
Domain refers to numbers on the x-axis.
Both of those lines will never reach -3, just come extremely close to it.
Answer:
AABC and AXYZ are similar triangles. The lengths of two sides of each triangle are shown. Find the lengths of the third side of each triangle
Remember, rise/run is the easiest way to determine slope
y=mx+b is form
mx is slope, whilst b is y int
so, answer? y=-3x-2
Or A.
B
If you have the variable near a division sign you automatically have to do the inverse opperations. You would have to multiply on the problem and each answer was either +, -, /, or x. Therefore, the answer is B.
Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
