Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56
we have the factors 2 x 2 x 3 x 5 x 7 = 420. It can also be written in exponential form as 22 x 31 x 51 x 71.

B) 70.5
Step-by-step explanation:
Median = middle value when the values are placed in order.
If there are two middle values, the median is the mean of those two values.
<u>Class 1</u>
45 46 51 52 53 53 61 63 64 65 66 68 70 <u>70 71</u> 73 76 77 79 81 82 83 84 87 90 92 93 95
There are 28 values in Class 1.
Therefore, there are two middle values: 14th and 15th values
14th value = 70
15th value = 71
