Which linear function has a graph that includes all of the points in the table?
egoroff_w [7]

Answer:

B. f(x) = 5x - 7

Step-by-step explanation:

✔️Using the table of values given, find the slope (m) and y-intercept (b) of the line of the graph that represents the table, then write the function in slope-intercept form.

✔️Slope (m) using (0, -7) and (2, 3):

Slope (m) = ∆y/∆x

Slope (m) = (3 -(-7))/(2 - 0)

Slope (m) = 10/2

Slope (m) = 5

✔️ y-intercept (b):

b = -7, because where x = 0, y = -7, which is the point where the y-axis is intercepted by the line of the graph.

✔️Write the linear function in slope-intercept form by substituting m = 5 and b = -7 into f(x) = mx + b

Thus:

f(x) = 5x + (-7)

f(x) = 5x - 7

Therefore, the linear function that has a graph that includes all the points in the table would be f(x) = 5x - 7.

(2x-7)-(4x^2+6x-3)+(x^2+4)
masha68 [24]

Answer:

-3x^2-4x

Step-by-step explanation:

Simplify:

\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)

=2x-7-\left(4x^2+6x-3\right)+x^2+4

Group same factor:

=-\left(4x^2+6x-3\right)+x^2+2x-7+4

Add :

=-\left(4x^2+6x-3\right)+x^2+2x-3

Apply the distributive law: -(a+b) = -a - b

-\left(4x^2+6x-3\right)=-4x^2-6x+3

=-4x^2-6x+3+x^2+2x-3

Group same factor:

=-4x^2+x^2-6x+2x+3-3

Subtract:

=-4x^2+x^2-6x+2x

Add:

=-3x^2-6x+2x

Group same factor:

=-3x^2-4x

Hence answer = -3x^2-4x

HELP PLEASE
ohaa [14]

Answer:

I don't believe that it will be viable by the time i am a senior, because the USA is so in debt, and they are having enough trouble as it is, supporting today's retirees and seniors. I wish it would be viable, but it is highly unlikely the government will not be able to support it.

To find 5, Beau found 22 = 4 and 32 = 9. He said that since 5 is between 4 and 9, 5 is between 2 and 3. Beau thinks a good estim
shusha [124]

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
