Help please ASAP really need this

Mathematics
1 answer:
Dimas [21]2 years ago
6 0

Answer:

Blue Line: y = 4x - 1

Green Line: y = -x + 6

Red Line: y = -x

Step-by-step explanation:

Looking at the equation y = mx + b

- The first giveaway is that the green line is the highest y-intercept (b- value). So we can say it's y = -x + 6

- Second giveaway is that the blue line has the lowest y-intercept (again the b- value). So we can say it's y = 4x - 1

- Third giveaway is that the red line has the same x-intercept AND y-intercept which is y = -x. Both intercepts are (0, 0).

Lastly, the rest of the statements are true in correspondence of the last 3 statements.

Point B ∈ |AC| so that AB:BC=2:1. Point D ∈ |AB| so that AD:DB=3:2. Find AD:DC
grigory [225]

Answer:

5:4

Step-by-step explanation:

If point B divides the segment AC in the ratio 2:1, then

AB=2x units and BC=x units.

If point D divides the segment AB in the ratio 3:2, then

AD=3y units and DB=2y units.

Since AD+DB=AB, then

3y+2y=2x\\ \\5y=2x\\ \\y=\dfrac{2}{5}x

Now,

AD=3y\\ \\DC=DB+BC=2y+x=2y+\dfrac{2}{5}y=\dfrac{12}{5}y

So,

AD:DC=3y:\dfrac{12}{5}y=15:12=5:4

Kelsey must pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pe
cupoosta [38]

Answer:

Kelsey must produce 34 more pendants.

Step-by-step explanation:

Giving the following information:

Fixed costs= $200

Unitary variable cost= $7.8

Selling price per unit= $13.5

Desired profit= $50

<u>To determine the number of units to be sold, we need to use the break-even point in units formula.</u>

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= (200 + 50) / (13.5 - 7.8)

Break-even point in units= 250/5.7

Break-even point in units= 43.86 = 44

Kelsey must produce 34 more pendants.
