Answer:

A

Step-by-step explanation:

y + yz

= x + \frac{1}{2} + (x + \frac{1}{2} )(2x - 3) ← expand factors using FOIL

= x + \frac{1}{2} + 2x² - 3x + x - \frac{3}{2} ← collect like terms

= 2x² - x - 1 → A

Which graph is the correct one?
cestrela7 [59]

Answer:

The upper graph

Step-by-step explanation:

We have two quadratic function here

y=-x^{2} +3x+5\\y=x^{2} +2x\\

If we perform the function f(x) + g(x), which is nothing more than the sum of the two functions, we obtain a linear function, since the quadratic terms are eliminated by themselves

5x+5

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. "Upon checko
Firdavs [7]
To check how much Tim will pay to refill the gas tank using one of the on-site pumps, we can create a linear model. We know from our problem that the Renter's charge $4.50 per gallon plus a $5.00 refueling, so let x be the number of gallons and y the total cost.
y=4.50x+5 
We also know that the fuel tank in the car is half empty and t<span>he car has a 12-gallon fuel tank, so half tank is 6 gallons. Lets replace the number of gallons in our linear model with 6 to fin the total cost: 
</span>y=4.50x+5 
y=4.50(6)+5
y=27+5
y=32

Now, to find how much Tim will pay if he decides to refuel the car on his own, we can also create a linear model.
Let x be the number of gallons and y the total cost. We know form our problem that <span>refueling the car on his own will cost $2.59 per gallon and the late fee charge is $32.
</span>y=2.59x+32
<span>We already know that half tank is 6 gallons, so 
</span>y=2.59(6)+32
y=15.54+32
y=47.54
<span>
Comparing the result of our two linear models we can conclude that the correct answer is: </span><span>b. It would be cheaper to return the car on time and pay the refueling costs.</span>
