The y- intercept of this equation is 4/1=4.00000
Explanation: y tells us how far up the line goes Notice that when x = 0 the value of y is 4/1 so this line "cuts" the y axis at y= 4.00000

Answer:

Step-by-step explanation:

The easiest way to find the y-intercept would be to put the equation into slope intercept form(y = mx + b). In the equation, b is the y-intercept. So we have to find b.

5y = 20 - 15x

Divide both sides by 5

y= -3x + 4

Now that it is in slope intercept form, we can look at what is plugged in for b, which is 4. So the y-intercept is 4.

Mariana bought 7 bags of candy. There were 61 pieces of candy in each bag. How many pieces of candy did Mariana buy?
Anna11 [10]

Answer:

4. A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost
Pani-rosa [81]

Answer:

The total cost for 8 hours of work is $425.

The total cost for 10 hours of work is $525.

The total amount the plumber earns is made up of a fixed charge and a variable charge. A fixed charge is a charge that remains constant regardless of the number of hours the plumber works. The fixed charge is $25. The variable charge is the charge that increases per hours worked. The variable charge is $50 per hour.

Cost = fixed charge + variable charge

C = $25 + $50h

The total cost for 8 hours

$25 + $50(8)

$25 + $400

= $425.

The total cost for 10 hours

$25 + $50(10)

$25 + $500

$525.

Step-by-step explanation:

hope this helps

Veronica has been saving dimes and quarters. She has 94 coins in all and the total value is $19.30. How many dimes and how many
Stolb23 [73]

Answer:

Step-by-step explanation:

d + q = 94.....d = 94 - q

0.10d + 0.25q = 19.30

0.10(94 - q) + 0.25q = 19.30

9.4 - 0.10q + 0.25q = 19.30

-0.10q + 0.25q = 19.30 - 9.40

0.15q = 9.90

q = 9.90/0.15

q = 66 <===== there are 66 quarters

d + q = 94

d + 66 = 94

d = 94 - 66

d = 28 <==== there are 28 dimes
