Answer:

57.5 marbles rounding to 58 if you do not have partial marbles

Step-by-step explanation:

The number of marbles is equal to the percent of the marbles times the total number of marbles

23 = 40% total marbles

Change to decimal form

23 = .40 M

Divide by .40

23/.40 = .40M/.40

57.5 = M

This question is odd since you can't have part of a marble

I would round up and have 58 marbles

58 *.40 = 23.2 marbles

Write in point-slope form an equation of the line that passes through the given point and has the given slope.

andre [41]

The point-slope form:

$y-y_1=m(x-x_1)$

3. (4, -2); m = 1/4

$y-(-2)=\dfrac{1}{4}(x-4)\\\\\boxed{y+2=\dfrac{1}{4}(x-4)}$

4. (-3, 5); m = -4/3

$y-5=-\dfrac{4}{3}(x-(-3))\\\\\boxed{y-5=-\dfrac{4}{3}(x+3)}$

5. (2, 2); m= - 1

$\boxed{y-2-(x-2)}$

6. (-1, -5); m = 4

$y-(-5)=4(x-(-1))\\\\\boxed{y+5=4(x+1)}$
