(3x to the third power) (-6y to the 5th power)
-3x to the 3rd power and y to the 5th power
I can help you with no.1 it is 40
Answer:
x = 1 . 14
Step-by-step explanation:
5x + 7 + 2x + 1
5x + 2x + 7 + 1
= 7x + 8
= x = 8 / 7
x = 1.1 4
Hope this answer helps you :)
Have a great day

Answer:
y = - 6x - 2
Step-by-step explanation:
The straight line equation is y = mx + c
First step is to bring the equation given to this form, where you make y the subject.
Now you can easily note down the gradient(m1). You will need it to find the gradient(m2) of the perpendicular line, because m1 × m2 = -1
After you have that substitute the value and the values of x and y given to find c .
Lastly, substitute the value of m2 and c into y = mx + c to find the line that is perpendicular .
