Question 676752: Hi can you help me with this question? I need it answer by today.
4x + y = 4
kx + y = 6
Step 1 of 3
Write the first equation in slope-intercept form. Subtract
4x from each side of the equation
4x + y = 4.
rite the second equation in slope-intercept form. Subtract kx from each side of the equation
kx + y = 6.
y = + 6
Part (c)
2x + ky = 7
x + 2y = 4
Step 1 of 3
Write the first equation in slope-intercept form. Subtract 2x from each side of the equation
2x + ky = 1.
ky = + 1
Divide each term by k.
y =

Question 676091: James Millhouse is renting a car at a local rental agency. The cost of renting the car is $38 per day, plus $0.35 for each mile driven over 150 miles. James rented this car for one day and drove it over 150 miles.
a. What equation can be used to determine y, the total cost of the rental, if it is driven y miles?
b. James drove from Las Vegas to the south rim of the Grand Canyon, a distance of 280 miles. He then drove back to Las Vegas the same day along the same route to turn in his rental car. How much was the bill for his rental car?
c. If James only had $150 to spend on the rental car, how many miles could he drive?

Question 676784: Can you help me with this problem?
x + 2y = 5
kx + 3y = 3
For the system to be independent the slopes must not be the same. Study the two equations and complete the following inequality for the slopes.
− k/3=
Multiply both sides by −3.
k ≠
