Given these are like terms you can add them together as shown, leaving you with just 1k
However I wonder if you are missing a part of the problem
(1, -2) because the expression inside the square root must be > or = 0. The square root of a negative number is imaginary complex numbers.
x - 1 = 0
x = 1
then y = -2
If they intersect they have the same x and y values so we can say y=y which can be expressed as:
-7x/8+1/4=-3x/4+1/2 make all terms have a common denominator of 8
-7x/8+2/8=-6x/8+4/8 now multiply all terms by 8
-7x+2=-6x+4 add 6x to both sides
-x+2=4 subtract 2 from both sides
-x=2 divide both sides by -1
x=-2, now we solve for y using either original equation...
y=-3(-2)/4+1/2
y=6/4+1/2
y=6/4+2/4
y=8/4
y=2 so the lines intersect at the point:
(-2, 2)
Answer:
What is it?
Step-by-step explanation:
Not 100% sure but Eric can be 18.5 years old and his father can he 51.5 years old.
52 - 33 = 19; 52 + 19 = 71
51 - 33 = 18; 51 + 18 = 69
51.5 - 33 = 18.5; 51.5 + 18.5 = 70
I hope this helps.
