Answer:
A) 3y = x + 16
Step-by-step explanation:
The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.
Swapping coefficients, we get ...
-3y = x + c
Negating the y-coefficient gives ...
3y = x + c
Filling in the given point, we have ...
3(5) = -1 + c
16 = c
The equation of the perpendicular line can be written as ...
3y = x + 16 . . . . matches choice A
_____
Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
The answer to your question is YES!
Your answer is the second option, -3, -6, -12, etc.
The information we are given tells us that a1 = -3 and an = 2 × a(n - 1). This means that if we want to find the value of a2, we just need to substitute -3 into the equation:
a2 = 2 × a1 = 2 × -3 = -6
And then to find a3, we substitute in a2, which in this case is -6, so:
a3 = 2 × a2 = 2 × -6 = -12
The only option with the first 3 terms as -3, -6, -12 is the second option, so that is the answer.
I hope this helps!
Product means the sum of two things i.e. the product of 1 and 2 is 3 <span>(1 + 2 = 3)
So the product of 3x and (3x+1) can be written as:
35 < 3x + 3x + 1
^ Greater than 35 i.e. at least 35
35 < 6x + 1
34 < 6x
34/6 < x
17/3 < x
5.67 (2dp) < x
