Tell whether the ordered pair (-1,3) is a solution of the system of linear equations. y=-7x-4 and y=8x+5

irinina [24]

Answer:

Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.

Step-by-step explanation:

(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5

Mr. Sarpy went to shoot some hoops on the basketball court. For every shot that he made within the three-point line he earned 2

Lostsunrise [7]

Answer:

x + y = 50 (1) and 2x + 3y = 115 (2); x = 35, y = 15

Step-by-step explanation:

Since x represents the number of 2 point shots and y represents the number of 3 point shots. If the total number of shots is 50, then x + y = 50 (1)

Also, the total 2 point shots is number of 2 point shots × points per shot = 2x and the total 3 point shots is number of 3 point shots × points per shot = 3y. Since the total number of points is 115, then

2x + 3y = 115 (2)

So, the system of equations are

x + y = 50 (1) and 2x + 3y = 115 (2)

We can solve for x and y by substituting x = 50 - y into (2)

So, 2(50 - y) + 3y = 115

100 - 2y + 3y = 115

100 + y = 115

y = 115 - 100

y = 15

So, x = 50 - y

= 50 - 15

= 35

Find the perimeter of the figure to the nearest hundredth.<br><br><br> Ps: it is not 30

frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

<u>Step 1: Add the straight sides together</u>

3+3+3+3+3+3 = 18 ft

<u>Step 2: Find the perimeter of the semi-circles</u>

The formula for the perimeter of semi-circle: 1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

<u>Step 3: Add all of them</u>

18 + 18.8 = 36.8 ft
