19 + 11 - 12² ÷ 3 (12 - 9) · 11)) - 7 =
katovenus [111]

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

First, subtract the numbers in the parentheses, then multiply by 11.

(12 - 9) = (3)

3 x 11 = 33

19 + 11 - 12^2 ÷ 3(33) - 7

Now, just multiply 33 by 3, and then square 12 (12 x 12).

19 + 11 - 144 ÷ 99 - 7

Now, you can divide 144 by 99, this is an infinite number, so..

144 ÷ 99 = 1.455

19 + 11 - 1.455 - 7

Finally add, then subtract.

30 - 1.455 - 7

28.545 - 7

The final answer is 21.545.

A line passes through the points (4,19) and (9,24). Write a linear function in the form y =Mx+b for this line
snow_lady [41]
Slope = y2-y1 / x2-x1
= 24-19/9-4
= 5/5
= 1

solve for b
y=1x+b
19=1(4)+b
19=4+b
15=b

the equation of the line is y=x+15
