Answer: D. Using the commutative property
explanation: you use the distributive property to get 10x-40. to combine like terms you add 40 to -40 and 20. and you decide 10 by both sides to get x by itself and the answer on the other side which equals 6.
Answer:
The intersection is point is (1/2 , 3)
Step-by-step explanation:
y = 4x + 1
y = -2x + 4
Next, move the x's to the side of the y's and change the positive to negative and vice versa.
y - 4x = 1
y + 2x = 4
Then, multiply the top or bottom equation by -1
-y + 4x = -1
y + 2x = 4
Or
y - 4x = 1
-y - 2x = -4
Then, subtract the y or add them to erase the y's
4x = -1
2x = 4
Or
-4x = 1
-2x = -4
Next, add or subtract the x's and what they equal
6x = 3
Or
-6x = -3
Then, find x
3/6x = 1/2
Or
-3/-6x = 1/2
x = 1/2
Finally, substitute 1/2 into one of the 2 equation
y= 2+1
y = 3
Or
y = -1 +4
y = 3
and get the point of (1/2 , 3)
Thanks for the Question
Answer: 1,767.15
Step-by-step explanation:
The radius is half the diameter, which is 15, therefore the radius is 7.5.
Volume=4/3*pi*radius cubed
In order to find these answers, we must put the equation into slope-intercept form.
Slope-intercept form has the following equation: Y=mx+b
M is the slope of the equation, and b is the Y-intercept. In this case, we have to isolate the Y variable and solve
So, the M in this case is 7, and the b is .5
So, the slope of the equation is 7, and the Y intercept is .5
