So if you want to fit the y-intercepts or "b", on the y-axis you should go by 25's [0, 25, 50, 75, 100...]

If the x-axis <u>does not have to</u> follow the same pattern (25's), you should go by 5's [0, 5, 10, 15, 20...]

y = 7x + 50

y = 2x + 175

First I would plot the y-intercepts for each equation, then plot a few points with x = 5, 10, 15 Then draw a straight line.

The point where the two lines meet/cross paths is your solution. It should be (25, 225) The x-axis is the number of miles, and the y-axis is the total cost. So Truck driver A and B would arrive/be at the same place/meet in 25 miles at the same cost of $225

What term best describes the point where the three medians of a triangle intersects

kirill115 [55]

CENTROID is the term used to describe the point where the three medians of a triangle intersect.

Centroid is the center of gravity of the triangle. It is one of the triangle's point of concurrency. Aside from "center of gravity", it is also known as "center of mass" and "barycenter".

Centroids are always inside the triangle. Since, the centroid is where three medians intersect, each median divides the triangle into two smaller triangles of equal area. The centroid is exactly two-thirds the way along each median.

Other types of triangle centers aside from Centroids are:
1) incenter
2) circumcenter
3) orthocenter

The art club is raising money for a new equipment. They need $842.36 to purchase new supplies and have received a $300.00 donati

Bumek [7]

Answer: Each fundraiser need to raise $ 135.59 in order to purchase the new net and equipment.

Step-by-step explanation:

Money required = $ 842.36

Donation amount = $ 300.00

Amount left to arrange = (Money required - Donation amount )

= $ (842.36- 300.00)

= $ 542.36

Number of fundraisers = 4

Money required to arrange by each fundraiser = (Amount left to arrange) ÷4

= $ (542.36÷4)

= $ 135.59

Hence, each fundraiser need to raise $ 135.59 in order to purchase the new net and equipment.

Nancy's garden has the dimensions shown 4 1/2 yard<br><br> 3 3/4 yd . She need find the area

Marina86 [1]

Answer:

The area of Nancy's garden is $16\frac{7}{8}\ yd^{2}$

Step-by-step explanation:

I assume that the Nancy's garden is a rectangle shape

To find the area first convert mixed number to an improper fraction

$4\frac{1}{2}\ yd=\frac{4*2+1}{2}=\frac{9}{2}\ yd$

$3\frac{3}{4}\ yd=\frac{3*4+3}{4}=\frac{15}{4}\ yd$

Therefore

The area is equal to

$A=\frac{9}{2}*\frac{15}{4}=\frac{135}{8}\ yd^{2}$

convert to mixed number

$\frac{135}{8}\ yd^{2=\frac{128}{8}+\frac{7}{8}=16\frac{7}{8}\ yd^{2}$
