You should add -77 to 77 because it will cancel out.

Additive inverses are two numbers that add to 0.
0 is the additive inverse of 0 since 0 + 0 = 0.
For all positive and negative numbers, to find the additive inverse of a number, change its sign.
The additive inverse of 1 is -1.
The additive inverse of 100 is -100.
The additive inverse of -9.5 is 9.5.
In this problem, the additive inverse of 77 is -77.

Answer:

t = 24 yards

Step-by-step explanation:

Since the trapezoids are similar then the ratios of corresponding sides are equal, that is

$\frac{t}{c}$ = $\frac{u}{d}$

Substitute in given values

$\frac{t}{0.4}$ = $\frac{15}{0.25}$ ( cross- multiply )

0.25t = 6 ( divide both sides by 0.25 )

t = 24

Answer:

(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product

(b) $y =2x +5$

Step-by-step explanation:

Given

The attached table

Solving (a): The rule of the table in words

First, we calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Using:

$(x_1,y_1) = (2,9)$

$(x_1,y_1) = (10,25)$

So, we have:

$m = \frac{25 - 9}{10 - 2}$

$m = \frac{16}{8}$

$m=2$

The equation is calculated using:

$y - y_1 =m(x - x_1)$

Using:

$(x_1,y_1) = (6,17)$

We have:

$y - 17 =2(x - 6)$

$y - 17 =2x - 12$

Make y the subject

$y =2x - 12+17$

$y =2x +5$

Hence, the rule is:

Multiply the input (x) by 2 and add 5 to the result of the product

(b): The rule, in algebra

As solved in (a), the rule is:

$y =2x +5$
