Your answer will be D

As y = -(x+2)(x-1)

Thus the external negative sign will flip the positive 2 into a negative & negative 1 into a positive; Resulting, y=(x-2)(x+1)

We can fairly easily solve this by looking at the direction the graph is pointing, and the x-intercepts.

We see that the graph is pointing down, so we can immediately rule out A and C because they both do not have a -

When we look at the x-intercepts we see they are -2 and 1

Only D when -2 or 1 are plugged in will return an answer of 0

Complete question

To find $\sqrt{5}$ , Beau found $2^2 = 4$ and $3^2 = 9$ . He said that since 5 is between 4 and 9, $\sqrt{5}$ , is between 2 and 3. Beau thinks a good estimate for $\sqrt{5}$ , is $\frac{2 + 3}{2} = 2.5$ Is his estimate high or low? How do you know?

Answer:

The estimation is high because 5 is very close to 4 so $\sqrt{5}$ will also be very close to $\sqrt{4}$ which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

$2.1^2 = 4.41$

$2.2^2 = 4.84$

$2.3^2 = 5.29$

From here we can see that $\sqrt{5}$ lies between 2.2 and 2.3 but is closer to 2.2

So a good estimate for $\sqrt{5}$ is 2.2

Answer:

Total temperature change 104.25 f.

Step-by-step explanation:

Average temperature change is calculated by dividing total temperature change by the total hours it took for the change.

We have been given the average temperature change.

We have to multiply average temperature change by the total number of hours it took for the temperature to change we get the total temperature change.

⇒ Total temperature change = Average temperature change * total hours

= $-4.17*25$

=104.25 f

a discounted concert ticket costs $14.50 less than the original price pp. you pay $53 for a discounted ticket. write an equation

spayn [35]

X = original price
x - 14.50 = 53 <== ur equation

x - 14.50 = 53
x = 53 + 14.50
x = 67.50...original price
