2 answers:

8 0

x − 2y = 5
2x − 4y = 10

multiply the 1st equation by 2 then
2x - 4y = 10
2x − 4y = 10
-------------------subtract
0 = 0

While testing a new pesticide, an agricultural scientist uses two functions to predict the yields of two same-sized potato farms

Pepsi [2]

Answer:

A. h(x)= -5.86x^2 + 23.37x + 34

Step-by-step explanation:

If the scientist uses the same amount of pesticide on the two farms then the x's of the functions are the same.

Then, the combined yield $h(x)$ of the two farms is just the yield of the first farm plus the yield of the second farm:

$h(x)=f(x)+g(x)$ .

Now, since

$f(x)= -2.43x^2+10.37x+9$

and

$g(x)= -3.43x^2+13x+25$ ,

then

$h(x)= (-2.43x^2+10.37x+9)+(-3.43x^2+13x+25)$

we add the coefficients of the corresponding terms to get:

$h(x)= (-2.43x^2-3.43x^2)+(10.37x+13x)+(9+25)$

$\boxed {h(x)=-5.86 x^2 + 23.37 x + 34.}$

Which is choice A.
