Assuming that there is supposed to be a + sign in front of the 2 and 4; the answer is as follows.
3(x+2)+4(x-5)=10
3x+6+4x-20=10
7x-16=10
7x=16
x=2 2/7
Hope this helps :)
Answer:
y = -5x + 19
Step-by-step explanation:
Note that the equation of any line parallel to y= -5x+7 has the same form as y= -5x+7, but a different constant. Knowing that this new line passes thru (2,9), we determine the value of this constant as follows: 9 = -5(2) + C, or 9 = -10 + C. Then C = 19, and the equation of this new line is
y = -5x + 19
Given that formula
((4-(-2))^2- (5-5))^1/2
((4+2)^2 -(0))^1/2
((6)^2 -0)^1/2
(36)^1/2
The answer is 6
(Note the 1/2 is also a substitute for the square root sign)
Step-by-step explanation:

Try putting it on a timeline. It makes more sense that way :)
