Answer:
f(x) = -3x + 6
Step-by-step explanation:
The general linear function is;
y = mx + b
it can also be written as (x , f(x))
f(x) = mx + b
where m is the slope and b is the y-intercept
so we have the points ;
(0,6) and (4,-6)
So we have;
for f(0) to be 6, it means that the y-intercept b is 6
This is because the value of x at the y-intercept is 0
So we have this as;
f(x) = mx + 6
Now, let’s substitute the other point so as to get m
For the other point;
x = 4 and f(x) = -6
that means;
-6 = 4m + 6
4m = -6-6
4m = -12
m = -12/4
m = -3
So we have the equation as;
f(x) = -3x + 6
Answer:
Step-by-step explanation:
-9/6 im not sure so dont get mand if im wrong
The zeros are -6, -2, 4. A graphing calculator helps if you have difficulty factoring.
Answer:
12
Step-by-step explanation:
1/4 will be left so its 12
Answer:
x = 
Step-by-step explanation:
Multiply all terms in the equation by the lowest common multiple of 3 and 5, that is 15. This will eliminate the fractions in the equation
10(1 - 2x) - 30x = - 6 + 20(2 - 3x) ← distribute and simplify both sides
10 - 20x - 30x = - 6 + 40 - 60x
10 - 50x = 34 - 60x ( add 60x to both sides )
10 + 10x = 34 ( subtract 10 from both sides )
10x = 24 ( divide both sides by 10 )
x = 
=
