Answer:
59
Step-by-step explanation:
I think your equation is supposed to look like this:
(7 + 1)² - (11 + 3²)/4
Follow PEMDAS to solve (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
(7 + 1)² - (11 + 9)/4
(8)² - (20)/4
64 - (20)/4
64 - 5

Answer:
126
Step-by-step explanation:
9 ÷ 20 = 0.45
280 × 0.45 = 126
2^5 + (4 + 3 + 1) = 40
((5 x 3) + (4 + 1)) x 2 = 40
Answer:
-1/6
Step-by-step explanation:
The slope of the line can be found by
m = (y2-y1)/(x2-x1)
= (7-9)/(8 - -4)
-2 /(8+4)
-2/(12)
-1/6
Step-by-step explanation:
y - y1 = m(x - x1)
y + 1/2 = 3(x - 2)
y = 3x - 6 - 1/2
y = 3x - 13/2
