Answer:

The second step is subtracting 986 from both sides

Step-by-step explanation:

The reason is because you want to isolate the variable. You can't solve it if there are numbers along with the variable in an equation.

Answer:

$\boxed{(f + g)(x) = {x}^{2} - x + 6}$

Given:

$f(x) = {x}^{2} + 1 \\ \\ g(x) = 5 - x$

To Find:

$(f + g)(x) = f(x) + g(x)$

Step-by-step explanation:

$= > f(x) + g(x) = ({x}^{2} + 1) + (5 - x) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = {x}^{2} + 1 + 5 - x\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = {x}^{2} + 6 - x\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = {x}^{2} - x + 6$

The scale of a map says that 4 cm represents 5 km.

andriy [413]

Answer:

a. 3.2 cm

b. 6.25 km

Step-by-step explanation:

(4 km)/(5 km) = 0.8

4 km is 0.8 of 5 km, so in the map it is 0.8 of 4 cm.

0.8 * 4 cm = 3.2 cm

Answer: 3.2 cm

(5 cm)/(4 cm) = 1.25

5 cm is 1.25 times 4 cm, so it represents 1.25 * 5 km.

1.25 * 5 km = 6.25 km

Answer: 6.25 km

The width of a rectangle is 8 inches and the perimeter is 26 inches. What is the length of the rectangle?

fredd [130]

Length of the rectangle is 5 inches

Step-by-step explanation:

Step 1: Perimeter of the rectangle = 26 in and width = 8 in. Find the length.

Perimeter of the rectangle = 2(length + width)

26 = 2(length + 8)

13 = length + 8

length = 13 - 8

Length = 5 in
