Answer:

y=-3/5x+16

Step-by-step explanation:

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

m=(13-19)/(5-(-5))

m=-6/(5+5)

m=-6/10

simplify

m=-3/5

y-y1=m(x-x1)

y-19=-3/5(x-(-5))

y-19=-3/5(x+5)

y=-3/5x-15/5+19

y=-3/5x-3+19

y=-3/5x+16

nikklg [1K]
X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs

Each month, a local bakery pays $0.75 per square foot to lease 500 square feet of space in a building. The bakery must also pay
ElenaW [278]

Answer:

C=375+0.025d

Step-by-step explanation:

Given:

'C' represent total cost of lease. 'd' represents cost of sales in dollars.

Cost of 1 square foot of building = $0.75

Total area of the building = 500 square feet.

Sales tax on the total sales = 2.5%

Now, cost of 500 square feet area = Cost of 1 square foot × Total area

Cost of 500 square feet area = 0.75\times 500=\$375

Now, sales tax is 2.5 of total sales 'd'. This gives,

Sales tax = 2.5\%\times d=\frac{2.5}{100}d=0.025d

Now, total cost is the sum of least amount and total sales tax.

Total cost = Least amount + Sales tax

⇒ C = 375+0.025d

Vesnalui [34]

Answer:

<h2>The Parallelogram</h2>

Step-by-step explanation:

A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!

Also, we have two pairs of parallel sides: is parallel to , and is parallel to . So it is a parallelogram or a rhombus. Since the length of the sides are not equal, the quadrilateral is a parallelogram.
