Answer:

C = 50p +900

Step-by-step explanation:

Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).

Equation: C = 900 +50p

The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.

Answer:

Step-by-step explanation:

1) y = 3x + 1

When x = -1 , y = 3*(-1) + 1

= -3 + 1

y = -2

(-1 , -2)

When x = 0 , y = 3*0 + 1

y = 1

(0 , 1)

When x = +1 , y = 3*1 + 1

= 3 + 1

y = 4

(1 , 4 )

Plot these points in the graph and join the points.

2) y = 2x -1

When x = -1 , y = 2*(-1) - 1

= - 2 - 1

y = -3

(-1 , -3)

When x = 0, y = 2*0 - 1

y = -1

(0 , -1)

When x = +1 , y = 2*1 -1

= 2 - 1

y = 1

(1 , 1)

Need help on this one question please

Elan Coil [88]

P(x, y) Q(x,y)
P(-2, -1) start at 0. Go to the left two squares, then go down 1 square. mark a point there
Q(2, 4) start at 0. Go to the right two squares, go up 4 squares. mark a point there.
connect two points
make a right triangle
Then use the pythereom
$4^{2} + 5^{2} = (PQ)^{2}$
$41 = (PQ)^{2}$
$\sqrt{41} = PQ$
