Answer is c. for example - if you put in 5 as the x value, you get (5+8) squared. that simplified is 13 squared, which is 169.
all x values on the table, when plugged into the third equation, end up with the correct y value

What is -157/20 as a decimal

abruzzese [7]

$-\frac{157}{20}=-\frac{140+17}{20}=-\left(\frac{140}{20}+\frac{17}{20}\right)=-7\frac{17}{20}\\\\-7\frac{17}{20}\to\ divide\ 17\ by\ 20\to\boxed{-7\frac{17}{20}=-7.85}\\\\other\ way\\\\-7\frac{17}{20}=-7\frac{17\cdot5}{20\cdot5}=-7\frac{85}{100}=\boxed{-7.85}$

calculates the sum of the first 8 terms of an arithmetic progression starting with 3/5 and ending with 1/4

N76 [4]

We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

<h3>How to get the sum of the first 8 terms?</h3>

In an arithmetic sequence, the difference between any two consecutive terms is a constant.

Here we know that:

$a_1 = 3/5\\a_8 = 1/4$

There are 7 times the common difference between these two values, so if d is the common difference:

$a_1 + 7*d = a_8\\\\3/5 + 7*d = 1/4\\\\7*d = 1/4 - 3/5 = (5 - 12)/20 = -7/20\\\\d = -1/20$

Then the sum of the first 8 terms is given by:

$3/5 + (3/5 - 1/20) + (3/5 - 2/20) + ... + (3/5 - 7/20)\\\\8*(3/5) - (1/20)*(1 + 2 + 3+ 4 + 5 + 6 + 7) = 3.4 = 34/10 = 17/5$

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

The sum of the measures of two complementary angles exceeds the difference of their measures by72°. Find measure of the smaller

weqwewe [10]

Answer: 18

Step-by-step explanation:

this is because complementary angles add up to 90 degrees so you would just subtract 72 from 90 to get your answer :)
