An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.

You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.

y = mx + b

1 = 4(-2) + b

1 = -8 + b

9 = b

Now we can use that and the slope to create the equation y = 4x + 9

9. What's the least common multiple (LCM) of 2, 6, and 8?

algol [13]

Answer:

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24

6, 12, 18, 24

8, 16, 24

They all share 24 so this is the LCM

Hope this helps

we are given

In a particularly sunny month, Solaire's solar panels generated 110 percent as much power as expected.

so, we need to change percent into fraction to get our value

we can write

110%= $\frac{110}{100}$

now, we can simplify it

and we get

110%= $\frac{11}{10}$

so,

Solaire's solar panels generate $\frac{11}{10}$ of the expected amount of power.............Answer

Well, if there are 12 eggs grouped together, and 5 of them hatch to be snakes.... More than likely the other 7 will also turn out to be snakes because the eggs are all grouped together.

What is the length of each side ? help please

Margarita [4]

Lengths are 11cm , 13cm , 16cm , 12cm

Step-by-step explanation:

Perimeter = Sum of measure of all the sides of quadrilateral.

In the question , perimeter = 52 cm

So,

$x + (x + 2) + 2(x - 3) + (x + 1) = 52$

$= > x + x + 2 + 2x - 6 + x + 1 = 52$

$= > 5x - 3 = 52$

$= > 5x = 52 + 3 = 55$

$= > x = \frac{55}{5} = 11$
