Consider the rule y = 5x + 7.

maksim [4K]

Answer:

see below

Step-by-step explanation:

Consider the rule y = 5x + 7.

a. How many tiles are in Figure 0?

In figure 0, we let x=0

y = 5*0+7 = 0+7 = 7

b. Which figure has 37 tiles?

This means y = 37

37 = 5x+7

Subtract 7 from each side

37-7 = 5x+7-7

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

Figure 6 has 37 tiles

c. In the equation y = mx + b, what do the letters m and b represent?

m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0

A window is shaped like a parallelogram. The base is 16 inches long. The area is 608 square inches. What is the height of the wi

OleMash [197]

Answer:

The height of the window is 38 inches.

Step-by-step explanation:

Given:

A window is shaped like a parallelogram.

The base is 16 inches long.

The area is 608 square inches.

Now, to find the window's height.

Let the height be $h.$

The area = 608 square inches.

The base ( $b$ ) = 16 inches.

Now, to get the height of the window we put formula:

$Area =b\times h\\\\608=16\times h\\\\Dividing\ both\ sides\ by\ 16\ we\ get:\\\\38=h\\\\h=38\ inches.$

Thus, the height is 38 inches.

Hence, the height of the window is 38 inches.

Simplify the following expression 5-⁵/2 x 5⁹/2

yarga [219]

Given:

Consider the given expression is

$5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}$

Using properties of exponents, we get

$=5^{-\frac{5}{2}+\frac{9}{2}}$ $[\because a^ma^n=a^{m+n}]$

$=5^{\frac{-5+9}{2}}$

$=5^{\frac{4}{2}}$

$=5^{2}$

$=25$

Therefore, the simplified form of given expression is 25.
