Answer:
infinitely many
Step-by-step explanation:
12x + 1 = 3(4x + 1) - 2
Distribute
12x + 1 = 12x + 3 - 2
Combine like terms
12x+1 = 12x +1
Subtract 12x from each side
1 =1
Since this is always true, we have infinite solutions
Answer:
3/10
Step-by-step explanation:
Subtract the sum of 1/3, 4/15 and 1/10 from 1:
10/30 + 8/30 + 3/30 = 21/30, or 7/10
Then: 1 - 7/10 = 3/10
Answer:
She can type 225 words in 10 minutes
Step-by-step explanation:
We can find the rate by dividing the number of words by the time
90 words/ 4 minutes
22.5 words per minute
Now to find the number of words in 10 minutes, multiply the rate times the time
22.5 * 10 = 225
She can type 225 words in 10 minutes
Answer:
range: {y | y>= -8)
Step-by-step explanation:
We have a radical here.
y = root( x + 1) - 8
y is defined as long as x+1 >= 0
so domain must be x > -1
y values would start from -8
and go upward.
range: {y | y>= -8)
