Answer:

-1/a

Step-by-step explanation:

If a doesn't equal 0 and the sum of x and 1/a is 0, what does x equal?

the sum of x and 1/a is expressed as;

x + 1/a

Equating this to zero

x + 1/a = 0

Find x:

Substract 1/a from bith sides

x + 1/a - 1/a = 0- 1/a

x = -1/a

Hence the value of x is -1/a

Answer:

y = 4.375x + 2.5

Step-by-step explanation:

The equation of the line is expressed as y = mx+c

m is the slope

c is the intercept

Using the coordinate points (0, 2.5), (4, 20)

Slope m = 20-2.5/4-0

m = 17.5/4

m = 4.375

Get the intercept

Substitute (0, 2.5) and m = 4.375 into y - mx+c

2.5 = 4.375(0) + c

2.5 = c

Get the equation required

y = 4.375x + 2.5

Annie brought nickels, dimes and quarters to the store. If she has at least one of every coin, they add up to $1.00, and Annie h
mojhsa [17]
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
