Step-by-step explanation:
- 9x-3=60°{each angle of equilateral triangle is 60°}
- 9x=60+3
- x=63/9
- x=7
so,
hope it helps.
Answer:
-5x + y = -1 or y = 5x - 1
Step-by-step explanation:
5x - y = 9
-5x - 5x
__________
-y = -5x + 9
__ ______
-1 -1
y = 5x - 9
__________________________________________________________
-6 = 5[-1] + b
-5
-1 = b
y = 5x - 1
If you want it in <em>Standard </em><em>Form</em>:
y = 5x - 1
-5x -5x
_________
-5x + y = -1 >> Line in <em>Standard</em><em> </em><em>Form</em>
I am joyous to assist you anytime.
Let's factorise it :
![\: {\qquad \dashrightarrow \sf {x}^{3} (x + 3) + [-5(x + 3)] }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%20%7Bx%7D%5E%7B3%7D%20%28x%20%2B%203%29%20%2B%20%5B-5%28x%20%2B%203%29%5D%20%20%7D)
Using Distributive property we get :
⠀
Therefore,
In a slope intercept equation in the form of y=mb+b,
m is the slope. m is the coefficient of x, meaning it is the number x is multiplied by. In this case, m happens to be
-5
which is your answer
