A theater has 43 seats in the first row. There are 49 seats in the second row, 61 seats in the third row, and 79 seats in the fo

mihalych1998 [28]

43 to 49 is 6
49 to 61 is 12
61 to 79 is 18
add 6 to each
79=4th row
79+18+6=79+24=103
103+24+6=103+30=133
133+30+6=133+36=169

7th row=169 seats

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

Y_Kistochka [10]

Answer:

y= 8x +7

Step-by-step explanation:

slope-intercept form:

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

$gradient = \frac{y1 - y2}{x1 - x2}$

Thus, gradient of the line

$= \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8$

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.

Answer:

$a){10}^{0} \\ b) {10}^{ - 7} \\ c){10}^{7} \\ d) {10}^{1}$

Step-by-step explanation:

${1000}^{ - 3} = {10}^{3 + ( - 3)} = {10}^{0} \\ {0.0001}^{ - 4} = {10}^{ - 3 + - 4} = {10}^{ - 7} \\ {100}^{5} = {10}^{2 + 5} = {10}^{7} \\ {0.001}^{3} = {10}^{ - 2 + 3} = {10}^{1}$

hope this helps you.

Have a nice day!
