The original value of x was negative, then –x, the opposite-signed version of x, would have to be positive. For instance, if I start with x = –3, then –x = –(–3) = +3, which is positive.
Answer:
(c) 
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 
So the slope of the line which is perpendicular to y = 3x+2 will be 
Now (a) Line is given as 
its slope is 
so it will be not perpendicular
(b) Line is given as 
its slope is so it will be not perpendicular
(c) Line is given as its slope is 
so it will be perpendicular to the line y = 3x+2
(d) Line is given as 
its slope is 3 so it will not perpendicular to the line y = 3x+2
2a^3-4a^2+5a+3
Explanation:
For standard form you always start with the one that has the biggest exponent to the least one
Answer:
0.5625
Step-by-step explanation:
3/4 as a decimal is 0.75
0.75×0.75=0.5625
You should use a protractor to help you with this answer; without one it's really hard to draw a 62 degree angle on your own. Sorry!!!
