12x - 9y is 3 times 4x-3y

(4x-3y * 3 = 12x - 9y)

just multiply 10 * 3 =

30 (value of 12x-9y)

I WILL MARK AS BRAINLIEST AND AWARD A LOT OF POINTS PLZ HELP!!!!!!!!!!!!Michael, Ronald, Lidia, Alexandra, and Catherine are sha
Marina86 [1]

Answer:

36 fries

Step-by-step explanation:

Michael has a probability of 0.3.

Lidia has a probability of 0.1.

Alexandra has the probability of 0.32.

Catherine has the probability of 0.1.

Let the probability of Ronald be x

Sum of all the probabilities must be 1

So, 0.3+0.1+0.32+0.1+x=1

0.82+x=1

x=0.18

So, probability of Ronald is 0.18

We are given that here are 200 fries in the basket.

So, the number of fries that Ronald will eat = 0.18 \times 200 =36

Hence Ronald will eat 36 fries.

Which equation in point-slope form contains the point (4, –1) and has slope 3?
Andrew [12]

Answer:

y+1=3(x-4)

Step-by-step explanation:

Hi there!

We are given a slope of 3 and a point (4,-1).

We need to find the equation of the line in point-slope form

Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point

We have all of the needed information to substitute into the formula

First, let's label the values of everything to avoid any confusion

m=3

x1=4

y1=-1

now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*

y--1=3(x-4)

simplify

y+1=3(x-4)

That's it!

Hope this helps :)
