Answer:
Step-by-step explanation:
In any square with side length 
, the diagonal of the square is equal to 
. Since the side length of this square is 
, the diagonal is equal to 
.
Alternatively, you can form two 45-45-90 triangles with the diagonal of the square. The diagonal acts as the hypotenuse for the both these triangles, and the legs of both triangles are equal to the side length of the square. To find the length of the diagonal, use the Pythagorean Theorem, which states 
, where 
is the hypotenuse of the triangle, and 
and 
are the two legs of the triangle.
In this question, both legs are equal to , and we're solving for the diagonal, which is the hypotenuse in this case:
To multiply two fractions:
-- Multiply their numerators; the product is the numerator of the new fraction.
9 x 7 = 63 ; the new fraction is (63) / (something)
-- Multiply their denominators; the product is the denominator of the new fraction.
1 x 10 = 10 ; the new fraction is <em>63/10</em> .
The product of the two original fractions is 63/10 , or <em>6.3</em> .
(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1
