Answer:

option A. 3x - y = 2 and 3x - y = 1

Step-by-step explanation:

Using the rule of y-intercept which is the value of y when x equals 0

Option A: 3x-y=2 and 3x-y=1

y-intercepts will be ⇒ -2 and -1

Option B: 3x+y=2 and 3x-y=1

y-intercepts will be ⇒ 2 and -1

Option C: 3x-y=2 and 3x+y=1

y-intercepts will be ⇒ -2 and 1

Option D: 3x+y=2 and 3x+y=1

y-intercepts will be ⇒ 2 and 1

Comparing the results with the y-intercepts from the graph

From the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1

So, the system which is represented by the graph is option A

Bikes'R'Us manufactures bikes, which sell for $250. It costs the $180 per bike, plus a startup fee of $3,500. After how many bik

lions [1.4K]

Answer:

The bikes sold at break even by the manufacturer is 50 units

Explanation:

We know that break even point is given by the following formula,

$\frac{\text { Fixed costs }}{\text { (Price per unit - Variable costs) }}$

We are given startup fee = $3500 which is the fixed cost,

the bikes sell for $250 which is the price per unit and

cost per bike is equal to $180

So substituting these values in the formula we get

= $\frac{3500}{(250-180)}$

= $\frac{3500}{(70)}$ = 50

= 50 units which is the number of bikes sold at break even by the manufacturer.

What is the solution to the system of equations?

s344n2d4d5 [400]

Answer:

(3,2)

Step-by-step explanation:

Here's your given:

y = 4x - 10

y = 2

Because they both equal y, that means they equal each other:

2 = 4x - 10

Add 10 on both sides:

12 = 4x

Then, divide 4 on both sides:

3 = x

This represents the x coordinate.

Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:

y = 2

This represents the y coordinate.

Put the two values together to get: (3,2)

Write a summary of how to get the area of a parallelogram.

kow [346]

Answer:

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

I hope it's helpful!
