Answer:
a: y=70x
b: y=70x+100
c: They are parallel to each other, with equation b's line being 100 dollars above equation a.
Step-by-step explanation:
They both have the same slope (70), but new customers will have a y intercept of 100 because of the one-time fee.
Answer:
2
Step-by-step explanation:
2x – 3y + 5 – (x – 3y) = 11 – 2x . . . . . given
2x -3y +5 -x +3y = 11 -2x . . . . . . . . . . .eliminate parentheses
x +5 = 11 -2x . . . . . . . . . . . . . . . . . . . . . collect terms
3x = 6 . . . . . . . . . . . . . . . . . . . . . . . . . . add 2x-5
x = 2 . . . . . . . . divide by 3
The value of x is 2.
Answer:
C
Step-by-step explanation:
Using the Cofunction identity
sin(90 - x)° = cos x°, hence
cos80° = sin(90 - 80)° = sin10° → C
Write an equation to model this situation. Then complete the input-output table below; and graph the equation on the coordinate plane provided. If two quantities x and y are directly proportional to one another, (meaning if x is doubled, so is y; if x is tripled, so is y), they show direct variation.
