Answer:
other root: x = 9
p = 7
Step-by-step explanation:
first, find p:
(8)² - (3p - 4)8 + 11p -5 = 0
64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0
91 - 13p = 0
-13p = -91
p = 7
<u>plug in p to find the polynomial:</u>
x² - (3(7) - 4)x + 11(7) - 5 = 0
x² - (21 - 4)x + 77 - 5 = 0
x² - 17x + 72
<u>find the roots:</u>
we know that 8 is one of the roots, so one factor is (x - 8)
the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8
that number is -9
so the poly nomial factors to be: (x-8)(x-9)
so the roots are x = 8 and x = 9
Let m be the amount is measles vaccines. and p be the amount of polio vaccines . 4p would be the amount of polio doses, and 2m would be the amount of measles doses. So the amount is measles an polio doses combined equals 2m + 4p.
2m + 4p = 184
Multiple by sides by half
1/2(2m + 4p) =1/2•184
Simplify
M+2p=92
Now comes he slightly more complicated part. In an equation, both sides are equal, so you can subtract the right side of an eqaution from the right side of a different eqaution and do the same thing with the left side.
M+p=60 because they are the number of vacaines. We can subtract this equation from other equation.
M+2p=92
M+p=60
M-m is 0, so it leaves. 2p-p is p, so the left side of our new equation is p. 92-60 is 32, so we end up with p=32. Then you can subtract p from p+m to get that m is 28.
Hope this helps.
