Answer:

25 miles.

Step-by-step explanation:

First, it would help to write out the problem as equations.

The first company:   1x+100

The second company: 2x+75

Where 'x' is the number of miles.

Then, just solve for the two equations when they equal each other.

1x+100=2x+75    Equation

100=x+75            Subtract 1x from both sides.

25=x                    Subtract 75 from both sides.

Answer:

224

Step-by-step explanation:

<u>Base:</u>

A = Bh

A = 8(8) = 64

<u>Sides:</u>

A = 1/2 Bh

A = 1/2 8(10)

A = 40

<u>Then you do 40(4) because there are 4 sides:</u>

40 (4) = 160

<u>Then you add up the base and the sides:</u>

160 + 64 = 224

(I think this is the right answer)

What is the slope-intercept form of this equation?
kirill [66]

Answer:

y = -8x + 12

Step-by-step explanation:

Slope intercept form: y = mx + b

m ---> Slope   & b ----> y-intercept

8x + y = 12

Subtract 8x from both sides

y = -8x + 12

Use substitution. What is the solution to the system of equations? Use the drop-down menus to explain your answer.
Hoochie [10]

Answer:

The system of equations has one solution. The two equations are intersecting lines.

Step-by-step explanation:

if you want to use the substitution method, you would have to plug in y for 12x+2 in the second equation.

2(12x+2)=x+4

next, you have to distribute

24x+4=x+4

subtract 24x from each side

4=-23x+4

subtract 4 from each side

0=23x

divide each side by 23

x=0

now, plug in 0 to one equation.

y=12(0)+2

y=2

the lines intersect at one point, (0,2)

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri
Nady [450]

Do you notice anything strange about those points ?

(0, 1), 
(1, 2), 
(2, 4),
(3, 8).

The y-coordinate of each point is (2) raised to the  power of the x-coordinate.

First point:       x=0,  y=2⁰ = 1
Second point: x=1,  y=2¹ = 2
Third point:      x=2,  y=2² = 4
Fourth point:    x=3,  y=2³ = 8


The equation of the curve appears to be

                               y = 2 ^ x .

So, after 10 hours,  x=10, and  y = 2¹⁰ = 1,024 .
