70, Multiply 5 pieces by 12 friends and you get 60, then add the 10 pieces he originally took out, and you get 70
Answer:
y =6x+17
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-7- -1)/(-4 - -3)
= (-7+1)/(-4+3)
-6/-1
6
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 6x+b
Substitute a point into the equation
-1 = 6(-3) +b
-1 = -18+b
Add 18 to each side
17 =b
The equation is
y =6x+17
Answer:
about 28
Step-by-step explanation:
you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)
AB = 19* (sin 75/ sin ( 180 -75-64) )
AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...
X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
