Answer:

$y=-4x+2$

Step-by-step explanation:

Since, the slope intercept form of a line is,

$y=mx+c$

Here, the given equation is,

$4x=2-y$

$4x+y=2$ ( Additive property of equality )

$y=-4x+2$ ( Subtraction property of equality )

Hence, the equation that represents the equivalent equation of the given equation in slope-intercept form is,

$y=-4x+2$

First option is correct.

2 The diagram shows a

Strike441 [17]

Diagram? There is no diagram given.

$i = \frac{180(n - 2)}{n}$

$i = \frac{180(12 - 2)}{12} = \frac{180(10)}{12} = \frac{1800}{12} \\ i = 150\degree$

Cannot solve b without the diagram.

Find an equation of the line that contains the given point and is perpendicular to the given line. Using a graphing calculator t

Orlov [11]

The equation of the line is y=2x+1.

We must must transform the standard form equation 3x+6y=5 into a slope-intercept form equation (y=mx+b) to find its slope.

3x+6y=5 (Subtract 3x on both sides.)

6y=−3x+5 (Divide both sides by 6.)

y=− 3/6x+ 5/6

y=− 1/2x+ 5/6

The slope of our first line is equal to − 1/2.Perpendicular lines have negative reciprocal slopes, so if the slope of one is x, the slope of the other is − 1/x

The negative reciprocal of − 1/2 is equal to 2, therefore 2 is the slope of our line.

Since the equation of line passing through the point (1,3), therefore substitute the given point in the equation y=2x+b:

3=(2×1)+b

3=2+b

b=3−2=1

Substitute this value for b in the equation y=2x+b:

y=2x+1

Hence, the equation of the line is y=2x+1.

Eggs sell for $1.09 per dozen at the local supermarket. If the supermarket pays $8.00 dollars her case that consist of 12 dozen

WARRIOR [948]

Answer:

B. $5.08

Step-by-step explanation:

First find out how much the supermarket pays per dozen of eggs.

$8.00 / 12 dozen cartons per case = $0.66666

It costs the supermarket approximately $0.67 per dozen

Next find out the profit per dozen of eggs sold

$1.09 store price - $0.67 price store pays = $0.42

The supermarket profits about $0.42 per dozen sold

Finally find out the profit per case of eggs

12 dozen cartons * $0.42 profit per carton = $5.04

The supermarket makes about $5.04 per case so the best answer of the choices would be B. $5.08.
