81 9/10

Step-by-step explanation:

Answer:

Slope: 2

Y-intercept:  (0, -1) or - 1

Step-by-step explanation:

Given the linear equation, -4x + 2y = -2:

Transform the given equation into its slope-intercept form, y = mx + b:

-4x + 2y = -2

Add 4x to both sides:

-4x + 4x + 2y = 4x - 2

2y = 4x - 2

Divide both sides by 2 to isolate y:

[tex]\frac{2y}{2} = \frac{4x - 2}{2}[/tex]

y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).

28/40 can be simplified by dividing by 4 to get:  7/10

Answer:

y = 2x + 1

Step-by-step explanation:

1. Find the slope;  (change in y values)/(change in x values)

Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2

2. Find the y-intercept (b) using  the slope intercept formula: y = mx + b

    m = 2 and using point (1, 3) , solve for "b"

       y = mx + b

       3 = 2(1) + b

       3 = 2 + b

      1 = b

3.  Write the linear equation: y = 2x + 1

Answer:

4

Step-by-step explanation:

#1 has to be excluded, since it jumps from 4 to 5 and has a hole between x=4 and x=5

#2 loses the extreme values. It would be correct if the domain was [tex]2<x<5[/tex]

#3 is including values in the interval [tex]1<x \leq 2[/tex] which aren't in our domain.

#4 is the remaining one.

Answer:

42=3x+6

subtract 6 from both sides

42-6=3x+6-6

to get

36=3x

divide both sides by 3 to isolate x

36/3=3x/3

to get

12=x

Answer:

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

The maximum profit is $923.44 which is gotten when 83 T shirts are produced.

Given the function:

Profit = Revenue - Cost

Profit (P) = 100x - (0.6x²+0.52x+3200)

P = -0.6x² + 99.48x - 3200

The maximum profit is at dP/dx = 0, hence:

dP/dx = -1.2x + 99.48

0 = -1.2x + 99.48

1.2x = 99.48

x = 82.9

x ≅ 83

The maximum profit is at x = 83, hence:

P = -0.6(83)² + 99.48(83) - 3200

P = 923.44

Answer:

Answer:

A

Step-by-step explanation:

Both the input and output are being increased by 1.

A system of equations consists of at least two equations

The value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]

The equation is given as:

y = 2x - 4

The actual question is to solve for x.

So, we start by adding 4 to both sides of the equation

y +4 = 2x - 4 + 4

y +4 = 2x

Rewrite the equation as:

2x= y +4

Divide both sides of the equation by 2

[tex]\mathbf{\frac{2x}2 = \frac{y +4}2}[/tex]

Divide 2x by 2

[tex]\mathbf{x = \frac{y +4}2}[/tex]

Split the fraction

[tex]\mathbf{x = \frac{y}2 +\frac{4}2}[/tex]

Simplify

[tex]\mathbf{x = \frac{y}2 +2}[/tex]

Hence, the value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]
