Write the equation in slope-intercept form then change it to standard form with integer coefficients.

SCORPION-xisa [38]

Answer:

1. Slope-intercept form: $y = 2x - 4$

Standard form: $2x - y = 4$

2. Slope-intercept form: $y = \dfrac12x - 1$

Standard form: $x - 2y = 2$

3. Slope-intercept form: $y = \dfrac45x + \dfrac{21}{5}$

Standard form: $4x -5y = - 21$

Step-by-step explanation:

Slope intercept form: $y = mx + b$

where:

$y$ = y-coordinate
$m$ = slope
$x$ = x-coordinate
$b$ = y-intercept

Standard form: $Ax + By = C$

$\textsf{1. as} \ m=2: \ \ y = 2x + b$

$\textsf{at} \ (6, 8): \ \ 8 = 2(6) + b$

$\implies b = -4$

Slope-intercept form: $y = 2x - 4$

Standard form: $2x - y = 4$

$\textsf{2. as} \ \ m = \dfrac12: \ \ y = \dfrac12x + b$

$\textsf{at} \ (4, 1): \ \ 1 = \dfrac12(4) + b$

$\implies b = -1$

Slope-intercept form: $y = \dfrac12x - 1$

Standard form: $x - 2y = 2$

$\textsf{3. as} \ \ m = \dfrac45: \ \ y = \dfrac45x + b$

$\textsf{at} \ (1,5): \ \ 5 = \dfrac45(1) + b$

$\implies b = \dfrac{21}{5}$

Slope-intercept form: $y = \dfrac45x + \dfrac{21}{5}$

Standard form: $4x -5y = - 21$

Janine is packing carrots. Each large box holds 20 2-pound bags of carrots. If janine has 800 bags of carrots, how many boxes ca

grigory [225]

This is a division problem:

Each box holds 20 bags.

800 bags / 20 bags per box = # of boxes

40 boxes are needed.

In a Las Vegas casino, gamblers lose a mean of on each roulette game, with a standard deviation of . (Since the standard deviati

aivan3 [116]

Answer: Hello your question is poorly written attached below is the complete question

answer:

0.1515

Step-by-step explanation:

Number of bets = 200

mean number of losses = $0.2

Standard deviation = $2.74

<u>Determine P ( winning after 200 bets ) </u>

Average of 200 bets > 0. i.e. P( X > 0 )

considering normal distribution : μ = -0.2 , б = 2.74 , n = 200

applying Z - distribution

z = 0 - ( - 0.2 ) / ( 2.74 / √200 ) ≈ 1.03

∴ P ( z > 1.03 ) = 1 - P ( z < 1.03 )

= 1 - 0.8485 ( value gotten from z-table )

= 0.1515

3c+2f=22<br>I have to find a number for both c and f. What would be some answers/examples?

AleksandrR [38]

It is impossible to solve for 2 unknown variables in an equation. In order to solve this, you must think mentally.

What two numbers can you add to make 22?
A good example is 15 and 8.

Can 15 and 8 be divided into smaller numbers?
Yes.

15/3 = 5
8/2 = 4
^
Notice how I'm dividing by the coefficient? *3*c and *2*f

So C can be 5 and F can be 4.

3(5) + 2(4) = 22
15 + 8 = 22
22 = 22
