What number goes into 5,6,7 & 9?

Allisa [31]

The Least Common Multiple of 5, 6, 7, and 9 goes into 5, 6, 7, and 9. The Least Common Multiple of 5, 6, 7, and 9 is 630. If you multiply that by 2, 3, 4, and so on, you get a never-ending set of numbers that go into 5, 6, 7, and 9.

Please help, it's due really soon!

kipiarov [429]

Answer:

Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.

First, input is the x. Looking at the graph.

Input : 0, 10, 20

Second, output is the y. Looking at the graph.

Output : 20, 30, 40

Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.

Y-intercept (b) : 20

Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.

Slope (m) : 1/2

Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.

Equation : y = 1/2x + 20

I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!

Show how you found the slope and y-intercept

Irina-Kira [14]

Answer:

Slope: $\frac{5}{2}$

y-intercept: 0

Step-by-step explanation:

First, find the slope. Use two points given to you. In this case, I will use the following:

(x₁ , y₁) = (2 , 5)

(x₂ , y₂) = (4 , 10)

Use the following equation:

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

Plug in the corresponding numbers to the corresponding variables:

slope (m) = $\frac{10 - 5}{4 - 2}$ = $\frac{5}{2}$

Note the slope intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Plug in the slope into m for the equation:

$y = \frac{5}{2} x + b$

Choose a point to use to find b. In this case, I will use (2 , 5). Plug in 2 for x, and 5 for y:

$5 = \frac{5}{2}(2) + b$

Simplify. Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other:

$5 = \frac{5}{2}(2) + b\\5 = 5 + b\\5 (-5) = 5 (-5) + b\\b = 5 - 5\\b = 0$

Y-intercept: 0

The University of Central Florida’s cheerleading team has eighteen males and twenty-one females. If h represents the height of a

morpeh [17]

Answer:

The range of heights of the cheerleaders is the interval [58, 74)

All real numbers greater than or equal to 58 inches and less than 74 inches

Step-by-step explanation:

we have

$260 \leq 4h+28$

Divide the compound inequality into two inequalities

$260 \leq 4h+28$ -----> inequality A

$4h+28$ -----> inequality B

<em>Solve inequality A</em>

$260 \leq 4h+28$

Subtract 28 both sides

$232 \leq 4h$

Divide by 4 both sides

$58 \leq h$

Rewrite

$h \geq 58\ in$

<em>Solve the inequality B</em>

$4h+28$

Subtract 28 both sides

$4h$

Divide by 4 both sides

$h$

therefore

The range of heights of the cheerleaders is the interval [58, 74)

All real numbers greater than or equal to 58 inches and less than 74 inches
