Answer:

Step-by-step explanation:

→ Find the change in y coordinates

-6 --6 = 0

→ As the change in y is 0, the gradient is 0

Step-by-step explanation:

Here,

(8,-6)=(x1,y1)

(-4,-6)=(x2,y2)

we know, solpe of any line passing throgh (8,-6)&(-4,-6) be

slope(m)=(y2-y1)/(x2-x1)

m={-6-(-6)}/(-4-8)

m=o/-12

m=o

Describe the transformation using the values for slope (m) and the y-intercept b. Compare the graph to the parent y = x.

ra1l [238]

Answer:

See attached

Step-by-step explanation:

y = mx + b - slope-intercept form

m- is the slope, the greater the slope the steeper the line, it gets flatter when is getting closer to zero

b- y-intercept, if be is positive it indicates vertical shift up, when negative- vertical shift down

A rectangular storage container with an open top is to have a volume of 10 m3. The length of this base is twice the width. Mater

marshall27 [118]

Answer:

$ 327.08

Step-by-step explanation:

Let x = width of the container,

Then Length of the container = 2x

Let h = height of the container,

volume of the container can be calculated as length × width × height

= 2x × x × h

= 2x² h

Then we can say Volume =

= 2x² h=10

If we simplify inorder to get h

We have h= 5/x²

Then the area= (2L×h) +(2xh)

Where L is lenght

x= wish

h= height

= 2× 2x × h+ x× h

= 4x× 5/x + 2x × 5/x

Area = 30/x

Now, the area of the base = length × width

But from question, for the base costs $20 per square meter. Material for the sides costs $12 per square meter

Then the cost C(x)= 2x²× 20+30/x ×12

C(x)= 40x²+35/x²

If we differenciate wrt x we have

C(x)= 80-360/x²

If we equate C(x)=0the

80=360/x²

x= 1.651

If substitute to C(x)= 40x²+35/x²

C(x) = 40(1.651)² + 35/(1.651)²

We have cost= 327.08

Kevin cuts lawns during the summer months. He charges $10 plus $5 per hour. The algebraic model is C = 5h + 10, where C represen

Dafna1 [17]

Answer:

We have;

Hours (h), Total cost C

1, 5*1 + 10 = $15

2, 5*2 + 10 = $20

3, 5*3 + 10 = $25

4, 5*4 + 10 = $30

5, 5*5 + 10 = $35

Step-by-step explanation:

The given parameters are;

Kevin's fixed charge for lawn cutting = $10

Kevin's charge for lawn cutting per hour = $5

The total cost, C, for cutting lawn cutting by Kevin is C = 5h + 10
