Slope=(y2-y1)/(x2-x1)
(x,y)
(3,1)
(-2,5)
x1=3
y1=1
x2=-2
y2=5
slope=(5-1)/(-2-3)=4/-5=-4/5
slope=-4/5
answer is B
Answer:
Area = 5x^2 +7x -26
Step-by-step explanation:
The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.
In other words:
A_small = (x-3)(x-6) = x^2-9x +18
A_big = (2x+2)(3x-4) = 6x^2 -2x -8
A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)
= 6x^2 -2x -8 - x^2 + 9x -18
= 5x^2 +7x -26
Answer: 15 x (1/3)
Step-by-step explanation: 15 divided by 3 is 15 right. When you multiple 15 and 1/3 it is like taking one third out of 15. One third out of 15 is 5. Hope this helped! :P
Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
