She has 1 quarter, 1 dime and 13 nickels. So the probability that one coin at random is a nickel is 13/15.
My work:
1$= 100
1 quarter=25
1 dime=10
1+1+13= 15
25×1= 25
10×1= 10
5×13= 65
65+25+10= 100
Answer:

Step-by-step explanation:
There is enough information to make a equation in slope-intercept form.

'm' is the slope. 'b' is the y-intercept.
In the given question, 3 is the slope and 2 is the y-intercept. This means that:
m = 3
b = 2
Plug in the appropriate values:

Answer:
false
Step-by-step explanation:
7. D
8. D
9. D
10.C
for 7 & 8 you use the equation

your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation

plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
