Apply the properties of operations to find an equivalent expression for finding the total cost of the clothes.
levacccp [35]

Answer:

Total cost of the clothes = 4x + 2y

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Total cost of the clothes = 4y + 6x

Step-by-step explanation:

Meredith bought 4 T-shirts and 2 pairs of pants. If x is the cost of one T-shirt and y is the cost of one pair of pants, she’ll have to multiply the number of T-shirts by x and the number of pants by y to find the total cost of the clothes.

Write an expression for finding the total cost of the clothes?

Apply the properties of operations to find an equivalent expression for finding the total cost of the clothes?

B. Write an expression for finding the total cost of the clothes if Meredith bought 6 T-shirts and 4 pairs of pants. Also write an equivalent expression for that expression?

Let

x = cost of one T-shirt

y = cost of one pair of pants,

Total cost of the clothes = 4x + 2y

Equivalent expression for finding the total cost of the clothes?

Switch the cost of T-shirt and cost of one pair of pants

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Equivalent expression for finding the total cost of the clothes?

Total cost of the clothes = 4y + 6x

A line goes through the points (8,9) and (-2,4).
vazorg [7]
<h3>Answer:</h3>
  • slope = 1/2
  • equation: y = 1/2x +5
<h3>Step-by-step explanation:</h3>

Slope

The slope of the line between two points (x1, y1) and (x2, y2) is ...

... m = (y2 -y1)/(x2 -x1)

For your given points, the slope is

... m = (4 -9)/(-2 -8) = -5/-10

... m = 1/2

Equation

The point-slope form of the equation for a line can be written ...

... y = m(x -h) +k . . . . for a line of slope m through point (h, k)

Using the first point given and the slope just calculated, the equation for the line can be written ...

... y = (1/2)(x -8) +9

... y = (1/2)x -4 +9 . . . . eliminate parentheses; next, collect terms

... y = 1/2x +5
