Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
Answer:
5 and -4.5
Step-by-step explanation:
10/2=5
and -9/2=-4.5
-5 -4.5 -4 -3 -2 -1 0 1 2 3 4 5
Answer:
Factored form (linear): (4x+3)(x-3)(x-5)
Step-by-step explanation:
Using long division and factoring, we can find the answer. Since the root/zero of <em>5 </em>is given already, we can change this into a factor of <em>(x - 5)</em><em> </em>as 5 is a root.
Step 1: Long division. Divide f(x) by (x-5)
Once you do long division, you should have left over (x-5)(4x²+9x-9)
Step 2: Factor the quadratic
Since you can't do gcf, you have to leave the 4x as a factor. Once you factor out the quadratic, you should get the answer:
(x-5)(4x+3)(x-3)
Step 3: Rearrange (Optional)
(4x+3)(x-3)(x-5)
