This is the next one!!
pentagon [3]

Answer:

5

Step-by-step explanation:

1 ,3 ,0, 6 ,x

To find the mean, we add them all up and divide by the number of numbers

(1+3+0+6+x) / 5 = 3

Multiply each side by 5

(1+3+0+6+x) / 5 *5= 3*5

(1+3+0+6+x)  = 15

Combine like terms

10+x = 15

Subtract 10 from each side

10+x-10=15-10

x = 5

Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.
cupoosta [38]

Answer:

y=x+8

Step-by-step explanation:

Slope of straight line can be calculated as

m=\frac{y_2-y_1}{x_2-x_1}

Here (x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)

m =\frac{10-5}{2-(-3)}\\m=1

Equation of straight line in slope intercept form is

y-y_1=m(x-x_1)\\y-5=(x+3)

y=x+8
