Line one has the equation 7x - 4y = - 28 and line two
Pie

7x - 4y = -28

3x +4y = -12

Using the elimination method because y is already eliminated

10x = -40

So x = -4

Then plug the -4 into the first equation....

7(-4) - 4y = -28

-28 - 4y = -28

-4y = 0

y = 0

I got:  -4,0

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the g
Fiesta28 [93]
Parallel lines have equal slopes. so the equation y=-4x+5.has slope of -4 because this is in slope intercept form y=mx+b where m is slope.

so we know a parallel line will have slope -4

we have a point on the line so we will use point slope formula to solve.
y-y1=m(x-x1) where (x1,y1) is point on line
so we get
y-4=-4(x-0) to put in slope intercept form we solve for y
y-4=-4x
y=-4x+4 is an equation of a line parallel to y=-4+5 passing through (0,4)

Determine the constant rate of change (slope) of the linear function.
daser333 [38]

Answer:

A customer pays $12,975.00 for a $8,600.00 bill. Find the least amount of bills and coins to give change.

First calculate change amount

Change = Cash - Bill

Change = $12,975.00 - $8,600.00

Change = $4,375.00

Next calculate denominations and quantities of change that get us to 0

Our current target value is $4,375.00

The highest coin/dollar value <= $4,375.00 is 43 hundred-dollar bills

43 hundred-dollar bills = $4,300.00

Subtract $4,300.00 from our current total of $4,375.00 to get $75.00

Our current target value is $75.00

The highest coin/dollar value <= $75.00 is 1 fifty-dollar bill

1 fifty-dollar bill = $50.00

Subtract $50.00 from our current total of $75.00 to get $25.00

Our current target value is $25.00

The highest coin/dollar value <= $25.00 is 1 twenty-dollar bill

1 twenty-dollar bill = $20.00

Subtract $20.00 from our current total of $25.00 to get $5.00

Our current target value is $5.00

The highest coin/dollar value <= $5.00 is 1 five-dollar bill

1 five-dollar bill = $5.00

Subtract $5.00 from our current total of $5.00 to get $0.00
