Step 1: Define Systems

3x - 2y = 0

4x + 2y = 14

Step 2: Solve for x

Elimination

Combine equations:                     7x = 14Divide 7 on both sides:                 x = 2

Step 3: Solve for y

Define equation:                     3x - 2y = 0Substitute in x:                        3(2) - 2y = 0Multiply:                                   6 - 2y = 0Isolate y term:                         -2y = -6Isolate y:                                  y = 3

What is (6,2) rotation 270

Answers

Given:

The point is (6,2).

To find:

The image of given point after rotation of 270 degrees.

Solution:

Let the given point be P(6,2).

Rotation of 270 degrees means the figure is rotated 270 degrees counterclockwise about the origin. So, the rule of rotation is

[tex](x,y)\to (y,-x)[/tex]

Using this rule, we get

[tex]P(6,2)\to P'(2,-6)[/tex]

Therefore, the image of given point is (2,-6).

Alex is a stockbroker. Earns ​% commission each week. Last​ week, sold ​$ worth of stocks. How much did he make last week in​ commission? If he averages that same amount each​ week, how much did he make in commission in​ 2011?

In​ 2010, there were 12.4 million citizens of a certain country diagnosed with diabetes. This number of cases represents an increase of about 396​% over the number of cases in 1973. How many cases of diabetes were there in​ 1973?

Answers

Answer:

3,131,313

Step-by-step explanation:

Let X represent the number of cases with diabetes in 1973.

An increase of 396% in diabetes cases in 1973 would be;

12.4 million = 396/100 × X

12.4 million = 396X/100

Cross multiply

12.4 million × 100 = 396X

X = [(12.4 million × 100) / 396]

X = 3,131,313

Therefore, the number of diabetes cases in 1973 is 3,131,313 cases
