Yes. a negative subtracting a negative equals a positive, therefore it would be 7+12 which would equal 19. your friend is correct.
Answer:
m= -1
Step-by-step explanation:
When writing an equation of a line, if I know more than one point, does it matter. The first method is to us the slope-intercept equation and plug in values to solve for b. 5. The slope-intecept equation would be y = 34 x + 2 (y−5)=34x−3 (isolate y). What is the equation in point-slope form of the line given (-2,3);
Answer:
sin^2 A
Step-by-step explanation:
first expand the trigonometry
1(1-cosA)+cosA(1-cosA)
=1-cosA+cosA-cos^2 A
= 1-cos^2 A
from trigonometric identity sin^2 A + cos^2 A= 1
sin^2 A= 1- cos^2 A
=sin^2 A

Step-by-step explanation:
Left to right, the expressions simplify to π, -1, π^2, √2.
1. Perform the division and you get 5π-4π = π.
2. Perform the division and you get √4 -√9 = 2-3 = -1.
3. Perform the multiplication and you get π^2. (The radicals become √1.)
4. If you just multiply it out, you get (10/3)√(18/100) = (10/3)(3/10)√2 = √2.
