Answer:

1. $11.50 2a. 25 2b. Decrease by 10

Step-by-step explanation:

1. Let's write Marietta's wage before a raise as x

$12.25 = x + $0.75

$12.25 - $0.75 = x

x = $11.50

2a. Let's substitute p with the actual value ($170)

170 = 8n - 30

200 = 8n

n = 200/8 = 25

2b.

p = 8*25 - 40

p = 200 - 40 = 160

160 < 170 so the profit decreased

It decreased by 10 (170 - 160).

Does the equation y= 4x +3 show a proportional relationship between x and​ y
maxonik [38]

<u>Answer</u>

yes it does.


<u>Explanation</u>

The equation of a straight line is in the form of Y = mX + c, where m is a constant (the gradient) and c is the y-intercept.

The equation above, y= 4x +3 is the equation of a straight line.

y ∝ x

Introducing the constant of proportionality now become y = 4x. When like this the a line is a straight line from the origin but when we add 3 in the equation we have. Y = 4X + 3.

The equation remains proportional. This time the line passes through the point (0,3).

What is true about an equation with infinite solutions?
maks197457 [2]

Answer:

A. When both sides of the equation are simplified, the coefficients are the same.

Step-by-step explanation:

An equation has infinite solutions when both sides of the equation are simplified, the coefficients are the same.

For example, given the following equation:

3x + 8 = x + 2x + 8

Simplifying:

3x + 8 = 3x + 8

In this case, ALL values of 'x' satisfies the equation.
