C) This one is 'funny'.
Identity means exactly the same, like 1=1.
Notice that left and right sides all have the same x! So one needs to look at the constant term:
A) -3 = 3, Nope
B) -4 = -3+1=-2, Nope
C) 3 = 1/2*2+2 =1 +2 = 3 Yup!
D) 1.3*3 = 3-2, No way!

Step-by-step explanation:
Hello!
Let's use a couple of exponent rules:
Let's utilize the first rule and simplify the fraction.
<h3>Simplify</h3>
Now, we can utilize the second exponent rule, as we have a base to the power of a negative number.
<h3>Simplify</h3>
The answer is option 1, .
Answer:
The correct answer is D.
Step-by-step explanation:
We need to find the slope of 3x-4y=20.
3x-4y=20
-4y=-3x+20
y=(3/4)-5
Perpendicular lines will always have negative reciprocals, so we need to find a line that has a slope of -4/3 ( flip the numbers and add a negative) and passes through the points (1,-1). We can use the point-slope formula.
y-y1=m(x-x1), where m is slope.
Substitute values.
y-(-1)=(-4/3)(x-1)
Simplify
y+1=(-4/3)x+(4/3)
Multiply both sides by 3
3y+3=-4x+4
Add 4x
3y+4x+3=4
Subtract 3
3y+4x=1
The correct answer is D
