I can’t find a picture but i can explain how to find the LCM of two numbers.

Let’s say we want to find the LCM of 10 and 12.
We first write the prime factorization of both numbers:
10= 2x5

12= 2*2*3

We multiply the highest degree of the numbers:
That is, 2*2*3*5=60

You can also watch this video to get a better idea on how to find the LCM of two or more numbers.

Hope this helped.

Write the equation of the line that passes through the points (-8,-5) (5,−8)

Nikolay [14]

Answer:

y=-3/13x-89/13

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-8)-(-5)/5-(-8)

m=-3/13

y-y=m(x-x1)

y-(-8)=-3/13(x-5)

y+8= -3/13x+15/13

-8 -8

y=-3/13x-89/13

How do you solve You earn 15n 15n dollars for mowing n lawns. How much do you earn for mowing one lawn? Seven lawns?

Rudik [331]

Answer:

$15 for a lawn, $105 for seven lawns.

Step-by-step explanation:

The question is about the direct ratio problem. Logically, you will earn more if you mow more lawn.

The scheme for this ratio is given below:

15 n_________n lawns

x_________ 1 lawn

$x=\frac{15n*1}{n} = 15$

You will earn 15 dollars for mowing a lawn

When you mow 7 lawns, the scheme will be in this manner:

15 n__________n lawns

x__________7 lawns

$x=\frac{15n*7}{n}=105$

You will earn 105 dollars

Which equation represents the graphed function?

scoundrel [369]

Solution:

we have been asked to find

Which equation represents the graphed function?

As we can see in the graph, the line is passing through the point (2,0) and (0,-3).

As we know the equation of the passing through two points is given by the formula

$(y-y_1)=m(x-x_1)\\
\\
m=slope=\frac{y_2-y_1}{x_2-x_1}=\frac{-3-0}{0-2}=\frac{3}{2} \\$

So the equation of the line will be

$y-0=\frac{3}{2}(x-2)\\
\\
y= \frac{3}{2}x-3\\
\\$
