Store A because with option A, the couch is $400 and loveseat is $200 so to buy both it is $600 but she has the discount of $105 off so it would be $495 with option A. With option B, if she buy the couch for $400 and the loveseat for $170 plus the $20 off, the love seat will be $150. So add $150 to $400 and the price is $550. Option a is a cheaper option by $55

Find the slope of the line through the given pair of points, if possible. Based on the slope, indicate whether the line through
Sloan [31]

Answer:

Slope of line having points (3,-5) and (2,-2) is 3 and since the slope is positive do it rises. Option C is correct option.

Step-by-step explanation:

The formula calculate to find slope is: Slope=\frac{y_2-y_1}{x_2-x_1}

We are given points (3,-5) and (2,-2) so,

x_1=3, y_1=-5, x_2=2, y_2=-2

Putting values in formula and finding slope

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-(-5)}{2-3}\\Slope=\frac{-2+5}{1}\\Slope=3

So, Slope of line having points (3,-5) and (2,-2) is 3 and since the slope is positive do it rises. Option C is correct option.

The University of Southern California is located about 2.5 miles west and about 2.8 miles south of downtown Los Angeles. Suppose
Jlenok [28]
If x represents distance measured east of downtown, and y represents distance measured north of downtown, the circle of radius 40 centered at (-2.5, -2.8) will have an equation of the form
  (x - h)² + (y - k)² = r²
where the center is (h, k) and the radius is r. The locus of points 4 miles from USC will satisfy the equation
  (x +2.5)² + (y + 2.8)² = 1600

How do I solve for x?
zheka24 [161]
3.) 5x-6=0, Add 6 to either side -> 5x=6, divide each side by 5 -> x=6/5 ---- 4.) x+y/3=5, multiple each side by 3 -> x+y=15, move y to the other side -> x=-y+15
