The A+ Cell Company charges $40 per month and $0.30 per minute for each additional minute over 500 minutes. The cost can be writ

ten as a linear function, C(x)=0.3x+40, where x is the number of minutes over 500. If the company were to increase the $40 charge to $50, how would the graph of this function change?

Answer:

up 10

Step-by-step explanation:

The function would change from

C(x) = 0.3x + 40

to

C(x) = 0.3x + 50

The change is only to the y-intercept, so the graph of the function will move up 10.

The graph of a function f is shown below.<br> Find f (2) and find one value of x for which f(x) = -4
nadya68 [22]

Answer: a: -2, b: 0

Step-by-step explanation:

f(2) means that x=2, and we need to solve for y.

On the graph, it has a point of (2, -2) and since it's a function that is the only possible output. Therefore, f(2)=-2.

f(x)=-4 means that y=-4, and we need to solve for x.

On the graph, the point (0,-4) exists, and since the function contains only one output, it must be correct. Therefore, x=0.

Anyone helppp meee please ....

Yep, this one seems sneaky and confusing.  But it's not so bad if you remember the things you learned about parallel lines.  (It can't be too tough ... I learned them
in 1954 and I still know how to use them.)

Look at the picture.  Line ' l ' is parallel to line ' m ', and the horizontal line on the bottom (which is not labeled) is a transversal that cuts the parallel lines.

Did you learn that interior angles on the same side of the transversal are equal ?
I'm sure you did, although it may have a new name nowadays.

Anyway, with the help of that 'tool', angle-'B' and angle-'D' are equal.  So . . .

(angle-A + angle-B) = 120

angle-B = 65

angle-A = 120 - 65 = <u>55 degrees</u>.
