Find the equation of the linear function represented by the table below in slope-intercept form.

Degger [83]

Answer:

$y=10x-6$

Step-by-step explanation:

step 1

Find the slope

we have

(0,-6) and (1,4)

The slope is equal to

$m=(4+6)/(1-0)=10$

step 2

Find the equation of the line in slope intercept form

The equation of the line in slope intercept form is

$y=mx+b$

we have

$m=10$

$b=-6$ -----> y-intercept (given value in the table)

substitute

$y=10x-6$

Answer:First three terms: 11,20,29 .

Step-by-step explanation:

Write a systems of equations. tn=a+(n−1)d. sn=n2 (2a+(n−1)d). So,. 110=11+(n−1)d 726=n2(22+(n−1)d).

Find the coordinates of G if F(2,5) is the midpoint of line GJ and J and has coordinates (-2,8)

dimulka [17.4K]

Answer:

G(6,2)

Step-by-step explanation:

If point $F(x_F,y_F)$ is the midpoint of the segment GJ, where $G(x_G,y_G)$ and $J(x_J,y_J)$ , then

$x_F=\dfrac{x_G+x_J}{2},\\ \\y_F=\dfrac{y_G+y_J}{2}.$

In your case,

$F(2,5),\ J(-2,8),$

therefore,

$2=\dfrac{x_G+(-2)}{2},\\ \\5=\dfrac{y_G+8}{2}.$

Thus,

$x_G-2=4\Rightarrow x_G=6,\\ \\y_G+8=10\Rightarrow y_G=2.$

Sonja's house is 4 blocks west and 1 block south of the center of town. Her school is 3 blocks east and 2 blocks north of the ce

lorasvet [3.4K]

The answer is √58 = 7.62

So, if you draw this down, you will see that the direct distance is hypotenuse c of a right triangle which sides are 3 blocks (1 south and 2 north) and 7 blocks (4 west and 3 east).
Use the Pythagorean theorem:
c² = a² + b²
a = 3
b = 7

c² = 3² + 7²
c² = 9 + 49
c² = 58
c = √58
c = 7.62
