Answer:
3/6 or 1/2
Step-by-step explanation:
y2-y1 = 8-2 = 6
x2-x1 = 3-0 = 3
The point would be (3,6) or if simplified (1,2)
HOPEFULLY THIS HELPED :)
Answer:
(8,2)
Please make sure I interpreted your system correctly below.
x+2y=12
-x=-y-6
Step-by-step explanation:
I assume the system is
x+2y=12
-x=-y-6
-----------
I'm going to multiply both sides of equation 2 by -1 giving me
x+2y=12
x=y+6
I'm now going to plug equation 2 into equation 1.
(y+6)+2y=12 I replaced x with y+6 in the first equation
y+6+2y=12
3y+6=12
3y=6
y=2
So
x=y+6
x=2+6
x=8
The solution is (8,2)
Answer:
y = x-1
Step-by-step explanation:
The general equation of a line is y= mx+ b , where m is the slope of the line , and b is the y-intercept ( where the line intersects the y-axis)
For the points (x1 = 6, y1 = 5) and ( x2 = 13, y2 = 12) that are on the line give the
slope m = (y2-y1) / (x2-x1) = (12-5) / (13-6) = 7/ 7 = 1
Now the equation of the line became y = x+b , because the slope m= 1
To find b we have to substitute x and y of any of the 2 given points in our equation.
The point ( x= 6, y = 5) gives the equation 5 = 6 +b ; 5-6 = b; -1 = b
Now the equation of the line became y = x -1 , because the y- intercept, b=-1
We can set up this problem as an equation in order to determine the unknown number. Thus, x/4 - 7 = 7. Here, 7 less than one-fourth of the unknown number (x) is equal to 7. Add 7 to the other side, and you are left with x/4 = 14. Multiply both sides by 4 in order to eliminate the denominator of the fraction. Now, we are left with x = 56. When we put it all together, 1/4 of 56 = 14. And 7 less than 14 is 7. Hope this helps!
Answer:
Step-by-step explanation:
To subtract -7a^2+3a-9 from 5a^2-6-4
We have
5a^2-10--7a^2+3a-9
5a^2-10+7a^2+3a-9
Collect like terms
12a^2+3a-10-9
12a^2+3a-19
