Answer:
f(3) = 9
Step-by-step explanation:
In the given figure,
when x=3,
f(x)=9
substituting x=3 in f(x),
=> f(3)=9
Answer:
<h2><em><u>
h = 13</u></em></h2>
Step-by-step explanation:
Solve for h.
h - 6 = 7
h = 7 + 6
h = 13
------------------
check
13 - 6 = 7
7 = 7
the answer is good
<span>Equivalent fractions are numbers with the same value for a number.
Multiply the numerator as well as the denominator by the same number. Therefore its like multiplying by 1.
45/60
3/4 = 9/12
<u>45 </u>x <u>15
</u>60 15 = 3/4
<u>45</u> x <u>5
</u>60 5 = 9/12

Answer:

Step-by-step explanation:
According to the given table, the variables have a linear relation, because there's a constant change involved.
Notice that p-variable increases by one unit, while q-variable increases by 10 units. That means the ratio of change is

Then, we use one pair of elements, like (3,30), and the point-slope formula to find the equations.

Therfore, the equation that represents the table is 
45 seconds the difference from 7 45 to 8 is 15 plus another 30 to get 8:30 which is a 45 second difference
