Answer:

y = x

Step-by-step explanation:

Slope-intercept form is the form that looks like

... y = mx + b . . . . . . for slope m and y-intercept b

The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...

... y = 1·x + 0

... y = x . . . . . . without the identity elements

_____

Comment on the marked choice

The choice that is marked is the equation in point-slope form using the point E (4, 4). That is not the form requested by the problem.

I don’t understand how to do this

Simora [160]

It's looking for the measures

m<F + m<G = 180°

(4x)° + (8x)° = 180°

12x = 180°
÷12 ÷12

x = 15

check your work

m<F + m<G = 180°

(4x)° + (8x)° = 180°

4(15)° + 8(15)° = 180°

60° + 120° = 180°

Help, i've been trying for around 30mins and I can't figure it out.

omeli [17]

Answer:

<h2>Option A and C</h2>

Step-by-step explanation:

As,

$2 \sqrt{75} + 3 \sqrt{50}$

$= 2 \sqrt{25 \times 3} + 3 \sqrt{25 \times 2} (A)$

$= 2 \times 5 \sqrt{3} + 3 \times 5 \sqrt{2}$

$= 10 \sqrt{3} + 15 \sqrt{2} (C)$

One card from a deck of cards Is selected, it's is replaced, and another card is chosen. What is the probability that the first

Elis [28]

Answer:

1/ 8

Step-by-step explanation:

Given that:

Number of red cards in deck = 26

Number of diamonds in deck = 13

Number of cards in deck = 52

Recall :

Probability = required outcome / Total possible outcomes

Probability of choosing a red :

P(red) = 26 / 52 = 1/2

With replacement :

Probability of diamond :

P(diamond) = 13 / 52 = 1/4

Hence,

Probability of first card red, then second card diamond equals

P(red) * P(diamond)

1/2 * 1/4

= 1/8

A small business produces and sells balls. The fixed costs are $20 and each ball costs $4.32 to produce. Each ball sells for $8.

Gemiola [76]

Part 1:

Fixed Cost, f = $20

number of balls = n

Cost of each ball, c = 4.32

Price of each ball, p = 8.32

Equation for total cost:

Total Cost of balls will come by adding the cost of all balls and the fixed cost

Total Cost = number of balls made × Cost of each ball + fixed cost

C = 4.32n + 20

Equation for revenue:

Revenue = Number of balls made × price of each ball

R = 8.32n

Part 2:

Use the graphing method to determine how many balls must be sold to break even

Breakeven means Revenue = total Cost

This happens at a point (5,41.6) where n = 5 is the number of balls sold

and C = 41.6 is the total cost

When 5 balls are sold there will be breakeven

R = 4n - 20

C = 4.32n + 20

Red line represent Cost

Black line represent Revenue
