y < x + 1 is given, as are four possible answer choices.

One by one, subst. the answer pairs into this inequality and then determine whether or not the resulting inequality is true or not.

For the possible answer choice (-2,5), 5 < -2 + 1, or 5 < -1. FALSE.

Continue with the 2nd, 3rd and 4th points. Does the substitution of any of these pairs of coordinates result in a true inequality? Identify with one (or ones).

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

The price of grapes at the grocery store is $1.44 per pound. There are approximately 0.45 kilometers in a pound. To the nearest

Nadusha1986 [10]

0.45 * 2 is 0.9
$1.44 * 2 is $2.88
$1.44/9 is $0.16
$0.16 * 2 is $0.32
$2.88+$0.32 is $3.20

The answer is $3.20

8. what is the graph of the inequality in the coordinate plane? <br><br> y<-2

LekaFEV [45]

1) Draw the coordinate plane

2) Draw the line y = - 2

It is a line parallel to the y axis, two units below the origin

3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.
