1/3 * 9x = 3x
1/3 * 3 = 1
3x + 1 = 4x
3x + 1 = 4x
4x=4x
Answer:
g(x)= 5
Step-by-step explanation:
Evaluate F(X) for 2
3(2)-1
6-1
5
And that is the value of G(X)
Answer:
slope = 0
Step-by-step explanation:
recall that the equation of a line can be expressed as:
y = mx + b, where m is the slope and b is the y-intercept.
in our case we are given y = 3
which can be re-written:
y = (0)x + 3
if we compare this with the general equation above, we can see that
slope = m = 0
I think the answer is
y=-8/9x-1/9
Let h = hot dog
Let s = soft drink
4h + s = 6.30...Equation A
h + 4s = 4.20...Equation B
We have two equations in two unknowns. The unknowns are the variables h and s.
I will solve for s in Equation A by subtracting 4h from both sides.
s = -4h + 6.30
I will now replace s in Equation B with -4h + 6.30 to find the price of one hot dog.
h + 4(-4h + 6.30) = 4.20
h -16h + 25.2 = 4.20
-15h = -25.2 + 4.20
-15h = -21
Divide both sides by -15.
h = -21/-15
h = 21/15
h = 7/5
h = $1.40
We now know the value of one hot dog.
Go back to EITHER Equation A or B, replace h with 1.40, do the algebra and you will find the price of one soft drink.
