Which of these lines is perpendicular to the line y = 3x + 2?
Morgarella [4.7K]

Answer:

(c)  y=\frac{-1}{3}x+4  will be perpendicular to the line y = 3x+2

Step-by-step explanation:

We have given the the equation of line as y = 3x+2

We know the equation of line as y = mx+c , here m is slope and c is intercept

On comparing with standard equation of line m = 3

We know that slope of perpendicular line is =\frac{-1}{m}

So the slope of the line which is perpendicular to y = 3x+2  will be =\frac{-1}{3}

Now (a) Line is given as y=\frac{1}{3}x+3 its slope is \frac{1}{3} so it will be not perpendicular

(b)  Line is given as y=\frac{1}{3}x+2 its slope is \frac{1}{3} so it will be not perpendicular

(c)  Line is given as y=\frac{-1}{3}x+4 its slope is \frac{-1}{3} so it will be perpendicular to the line y = 3x+2

(d) Line is given as y=3x+\frac{1}{2} its slope is 3 so it will not perpendicular to the line y = 3x+2

How much money will you have if you started with $45 and put it in an account that earned 10% every year for 20 years
Veronika [31]
Probably it's all wrong
 4.5 = 10 %If is the same then 4.5*20+45=135
If not then 
FV=P(1+r)n45* (1+0.1)20 = 45*6.727=302.737

2(x-3)-12 = -4<br> How do I solve this equations
deff fn [24]

Answer:

x= 7

Step-by-step explanation:

1st step: Multiply the factor (outside number) with the numbers and variable(s) in the box. This results in 2(x-3) = 2x-6

2nd Step: continue the rest of the equation since there are no more brackets left so 2x-6-12=-4

3rd Step: send -12 to the other side of the equation (side changes sign changes) so it will become 2x-6=-4+12    (You are actually supposed to make the variable alone on one side of the equation so that you would be able to calculate its value)

4th step: 2x-6=8 ---> send -6 to the other side as well which will then result in 2x=14

5th step: since 2 is being multiplied by x, when you send it to the other side (to make x alone) you will divide 14 by 2 ( sign of 2 changes from multiplication to division)

Final Step: x=7
