Answer:
A
Step-by-step explanation:
this is because a range is simply a collection of numbers that can be found in the domain
and since there is no domain, we assume that the numbers are all in the domain
leading us to our answer a
Answer:
1. 12x+7
2. x=7
Step-by-step explanation:
1. 4(5x-1)-8x+11=?
multiply 4(5x-1)
20x-4-8x+11
Subtract 8x from 20x which is 12x
then subtract 4 from 11 which is 7
12x+7
Answer:
=62%
Explanation:
34/55=0.6181=0.62 rounding off to nearest 100.
34/55×100=0.62×100
=62%
Answer:
D. 69.2
Step-by-step explanation:
v= 3.14 ×2.1^2 × 5
v = 69.237
when you round it, it is
69.2 cubic cm
Y^2 - (y+5)^2 = 20
starting with (y+5)^2 that's y^2 + 5y + 5y + 25
then you change the signs and get
y^2 - y^2 - 10y - 25 = 20
so -10y = 45 >> 10y = -45 >> y = -4,5
answer: A
