Answer:
y= -3x-12
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Given that the slope is -3, m= -3.
Substitute the value of m into the equation.
y= -3x +c
Now, substitute the given coordinates into the equation.
When x= -5, y= 3,
3= -3(-5) +c
3= 15 +c
c= 3 -15
c= -12
Hence, the equation of the line is y= -3x-12
Answer:
The first one
Step-by-step explanation:
Multiplying exponents will just have to follow a rule.
Make sure that the base are the same otherwise, you keep it as is.
If they have the same bases, then just add the exponents.
= (5a^5)(6a^6)
= 30a^11
So the final answer is <span>30a^11.</span>
Answer:
10
Step-by-step explanation:
-2*2-3x+5=f(x)
-2*2-3(-3)+5=f(x)
-4+9+5=f(x)
5+5=f(x)
10=f(x)
