13. Simple problem when you divide a fraction by another you multiply by its inverse not by the same.
So 3x-12/x^2-9x+20 divided by 9x+54/x^2+x-30
Should be: 3x-12/x^2-9x+20 * x^2+x-30/9x+54
Now you can simplify it.
3(x-4)/(x-4)(x-5) * (x+6)(x-5)/9(x+6)
Or 3/(x-5) * (x-5)/9
Or 3/1 * 1/9
Or 3/9 = 1/3
The correct answer is
D) 1/2
because
5/10 = 1/2
Answer:
The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50
Step-by-step explanation:
c=.5m+5
y=mx+b - slope intercept formula
In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.
In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!
Answer:
(x=1) - Below
0-6 = 6
1
(-6x) = -6
(0 - (6x))+6 = 12
Step-by-step explanation:
Step 1: Subtract 6 from both sides.
−6x+6−6=0−6
−6x=−6
Step 2: Divide both sides by -6.
−6x/−6 =− 6/−6
Step 3: x = 1
Step-by-step explanation:
the answer is c i took the test btw
