Answer:
y= 0.05x + 50
Step-by-step explanation:
Slope intercept form: y= mx + b
The total monthly cost of the telephone plan is $50 plus a charge of $0.05 per minute.
The charge is <em>dependent</em> on the minutes used.
Whenever we see <em>per</em>, we automatically have our slope.
Slope: 0.05
And since 50 is the <em>independent</em> variable, 50 is our y-intercept.
y= 0.05x + 50
2x + 9 = 8
Subtract 9 from each side :
2x = -1
Divide each side by 2 :
x = - 1/2
Answer:
Step-by-step explanation:
If a point is dilated by a scale factor 'k' centered at the origin,
Coordinates of the image point becomes as,
(x, y) → (kx, ky)
By this rule,
Coordinates of the vertices of the image triangle, when preimage is scaled by a factor of 5 about the origin will be,
T(-1, -2) → T'(-5, -10)
U(2, -2) → U'(10, -10)
V(-1, 1) → V'(-5, 5)

Answer:
Option B.
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
