X+2y=5
-x+3y=6
Answer: (-3, 4)
x+2(0)=5
x=5
(0)+2y=5
y=5/2
-x+3y=6
Answer: x-intercept: A. y-intercept: C.
(-6,2)
Not sure, here though.
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
3/4(1/2x + 4) + 1/2(x − 1)
First use distributive property to remove the parentheses:
3/8x + 3 + 1/2x -1/2
Now combine like terms:
7/8x + 2 1/2
It’s 12:35, if you add 40+25 it equals 65, 60 minutes is an hour, subtract 65-60 and you’ll get 5. The hour brings you to 12:30 and then you add the remaining time (5 minutes), which will give you 12:35.
