What is the y-value for the solution to the system of equations below? 10x + 8y = -24 5x+6y = 2​

Mathematics

Y = -1.4

The simplest way to find the answer is to cancel out the x - values. Set both equations equal to zero.
10x + 8y + 24 = 0
5x - 6y - 2 = 0
Multiple the second equation by -2 so the x terms cancel out when you add them together.
10x + 8y + 24 = 0
-10x + 12y + 4 = 0

20y + 28 = 0
20y = -28
Y = -1.4

Area is Length x width.

Area = 4x * 5

Area = 20x

Replace A in the inequality:

Now you have 100 <= 20x <= 1,000

Now solve for x by dividing all 3 by 20:

5 <= x <=50

Check to see if they are viable:

4(5) x 5 = 20 x 5 = 100

4(50) x 5 = 200 x 5 = 1,000

Since the lowest number equals 100 and the largest number equals 1,000 all values of x would be viable. The answer is YES.

Dan has a conical lamp shade with an altitude of 6 inches and a diameter
Luda [366]

Answer:

226.22 in^2

Step-by-step explanation:

Given data

Height l= 6in

Diameter= 12in

Radius= 12/2= 6in

The expression for the total surface area of a cone is given as

TSA= πrl+πr^2

substitute

TSA= 3.142*6*6+3.142*6^2

TSA= 113.112+113.112

TSA= 226.22 in^2

Hence the TSA is 226.22 in^2
