What is the least common multiple of 8 and 10

Lynna [10]

40 is your answer. Because, you need the lowest multiple so we have to find it by making out a chart of their multiples

8, 16,24,32,40

10,20,30,40

The first same multiple they make is 40

Answer if u love cats & dogs

Answer:

(7, 5.25) lies on the graph.

Step-by-step explanation:

We are given the following values

x = 4, 6, 8, 12 and corresponding y values are:

y = 3, 4.5, 6, 9

Let us consider two points (4, 6) and (6, 4.5) and try to find out the equation of line.

Equation of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given as:

$y=mx+c$

where m is the slope.

(x,y) are the coordinates from where the line passes.

c is the y intercept.

Here,

$x_{1} = 4\\x_{2} = 6\\y_{1} = 3\\y_{2} = 4.5$

Formula for slope is:

$m = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m = \dfrac{4.5-3}{6-4}\\\Rightarrow m = \dfrac{1.5}{2}\\\Rightarrow m = \dfrac{3}{4}$

Now, the equation of line becomes:

$y=\dfrac{3}{4}x+c$

Putting the point (4,3) in the above equation to find c:

$3=\dfrac{3}{4}\times 4+c\\\Rightarrow 3=3+c\\\Rightarrow c =0$

So, final equation of given function is:

$y=\dfrac{3}{4}x$

$4y=3x$

As per the given options, the point (7, 5.25) satisfies the equation.

So correct answer is $(7, 5.25)$ .

Use the graph of the parabola to identify the domain and range of the function.

LekaFEV [45]

Answer:

Step-by-step explanation:

It's domain is side from side and so it can't be c or d. and it range goes to a positive number so it has to be B.

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?

Eduardwww [97]

Answer:

n = -4

Step-by-step explanation:

You must write and solve a symbolic equation.

n - 6 = 5(n + 2), or

n - 6 = 5n + 10

Combining like terms, we get:

-16 = 4n,

and so n = -4
