Answer:
c
Step-by-step explanation:
because mathematically 0 less than or equal to x less than or equal to 4 means starting from 0 up to 4 is the domain of the graph
but if we were asked about the range it was going to be all real number (B) because if the range means the value of y then y have solution in all the way down

Answer:
Just like combining like terms with the same variables, you combine like
radicals with the same number under the radical signs.
Step-by-step explanation:
Example:
3x + 2x
= 5x {combined like terms}
3√2 + 2√2
= 5√2 {combined like radicals}
Find a common denominator in the two fractions before you can do anything
Answer: Kate = 40/3 Her father = 50
Step-by-step explanation:
Let Kate's age in the present be K
And Kate's father's age in the present be F
3(K+5) = F+5
6(K-6) = F-6
Rearrange the first equation to get
3K+15 = F+5
3K+10 = F
Substitute that into the second question
6K-36 = 3K+10-6
3K = 40
K = 40/3
So F = 3*40/3+10 = 50
