Answer:
m=-2
the slope is -2
Step-by-step explanation:
<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.
The original equation log 0.0001 = -4 assumes the base of the logarithm is 10, so the exponential form is 10^ -4 = 0.0001
Firstly, you divide by -2 then |x| which equals 3 and the solutions x+3
Answer:
0.5x7
Step-by-step explanation:
Assuming that the original expression is 
, according to PEMDAS multiplication takes priority over addition and subtraction,, and therefore, from the choices given, 0.5 * 7 must be performed first.
