Determine which of the ordered pair is a solution for the equation 2x-3y=7
Vikentia [17]
<h3><u>The correct answer is: B.</u></h3>

We could use a graphing calculator to solve this easily, but let's just solve it by looking at the equation.

We'll need to turn this standard form equation into a slope-intercept form equation to be able to easily solve it.

Isolate y.

2x - 3y = 7

<em><u>Add 3y to both sides.</u></em>

2x = 3y + 7

<em><u>Subtract 7 from both sides.</u></em>

3y = 2x - 7

<em><u>Divide both sides by 3.</u></em>

y = 2/3x -7/3

Now, we can plug each x value in the answer choices into x to find the corresponding y value.

y = 2/3(7) - 7/3 = 2.34

As this y value does not match, A is not the answer.

y = 2/3(-4) - 7/3 = -5

This y value does match, so B is the correct answer.

y = 2/3(-9) - 7/3 = -8.34

This y value doesn't match either, so C is not the answer.

y = 2/3(9) - 7/3 = 3.67

This y value doesn't match either, so D is not the answer.

Log 0.0001=-4 to exponential equation
Keith_Richards [23]
The original equation log 0.0001 = -4 assumes the base of the logarithm is 10, so the exponential form is 10^ -4 = 0.0001

Arnold needs to simplify the expression below.
Lunna [17]

Answer:

0.5x7

Step-by-step explanation:

Assuming that the original expression is 4.3*3+ 11(8.2-0.5*7)-6, according to PEMDAS multiplication takes priority over addition and subtraction,, and therefore, from the choices given, 0.5 * 7 must be performed first.
