Answer:
C
Step-by-step explanation:
4x+3y=-24
eq. of any line perpendicular to given line is
3x-4y=a
4y=3x-a
y=3/4x -a/4
where a is an arbitrary constant.
Because the decimal is over 40 the answer is 15
Answer:
I think it's 3
Step-by-step explanation:
To calculate the gradient equals to
y(1)-y(2)
-----------
x(1)-x(2)
So - 5 - 1 = - 6
6 - 2 = 4
-6 - 3
--- = ----- x
4 2
And the first y intercept is 1 so I guess it's 3.
Just for refernece, not sure if I'm correct. Sry
Answer:
w=7.
Step-by-step explanation:
Divide 7 on both sides of the equation.
Given:
Consider the equation is
To find:
The value of x.
Solution:
We have,
Using properties of exponents, we get
![[\because \dfrac{a^m}{a^n}=a^{m-n},a^{-n}=\dfrac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%2Ca%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5D)
On comparing both sides, we get
Add 16 on both sides.
Multiply both sides by -1.
Therefore, the value of x is 8.
