Answer:
The x intercept is (-3,0)
The y intercept is (0,-6/5)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
2x+5y=-6
2x+0 = -6
Divide by 2
2x/2 = -6/2
x = -3
The x intercept is (-3,0)
To find the y intercept, set x =0 and solve for y
2x+5y=-6
0+5y = -6
Divide by 5
5y/5 = -6/5
y = -6/5
The y intercept is (0,-6/5)

Answer:
The number of pounds of:
Decaffeinated coffee = x = 5 pounds
Regular coffee = y = 9 pounds
Step-by-step explanation:
A 14 -pound mixture of coffee that contains both decaffeinated and regular coffee costs $37. The decaffeinated coffee costs $2 per pound, and the regular coffee costs $3 per pound.
Let the number of pounds of:
Decaffeinated coffee = x
Regular coffee = y
Hence, our system of equations =
x + y = 14..... Equation
x = 14 - y
2x + 3y = 37....... Equation 2
We substitute 14 - y for x in Equation 2
= 2(14 - y) + 3y = 37
= 28 - 2y + 3y = 37
= - 2y + 3y = 37 - 28
= y = 9 pounds
Solving for x
x = 14 - y
x = 14 - 9
x = 5 pounds
Therefore,
The number of pounds of:
Decaffeinated coffee = x = 5 pounds
Regular coffee = y = 9 pounds
