The slope of that equation is (1/3)x. To find the perpendicular slope of a slope, you would have to find the reciprocal. To do this:
Flip the slope, and add a negative. It'll equal to -3x. Visual representation:

now the perpendicular slope is -3, you will need to put this into point slope form, which is y - y1 = m(x - x1)
x1 = 5, y1 = -3
It'll equal to: y + 3 = -3(x - 5)
Now, you need to convert this to slope intercept form y = mx + b. All you need to do is just to distribute the -3 in that binomial, and move that 3 in the left side to the right side. It is easy!
Follow the representation, and there you go!

Answer:
wHOLE number
Step-by-step explanation:
IT is a whole number
Answer:
5) 13
6) 6
7) 8
8) 30
9) 3.464 = 3.46 = 3.5 = 4 (could be any of these just depends on what your looking for.)
10) i: 40^2 ii:84^2
Finding zeros or setting y ot f(n) equal to zero
and all you have to do is factor it, hoping you know how to do this
5. 0= n^2-2n-15
(n-5)(n+3)= 0
n-5= 0 n+3=0
n=5 and n=-3
6.t^2+6t=27
t^2+6t-27=0
(t + 9) (t-3)= 0
t=-9 and t=3
7. x^2-9x=-18
x^2-9x+18=0
(x-6)(x-3)= 0
x=6 and x=3
8. a^2 - 7a = 30
a^2 - 7a -30= 0
(a-10)(a+3)=0
a=10 and a=-3
hope that helps
Step-by-step explanation:
Hey there!
The equation is;
Shifting "2x" to left side and "2" to right side.
Simplify them to get answer.
Therefore the value of x is -7.
<u>Check</u><u>;</u>
3 × -7 + 2 = 2 × -7 -5
-19 = -19 ( True ).
So, your answer is option B.
