Answer:
6
Step-by-step explanation:
This function corresponds to 'even' function, then
in order to calculate the 'x' of the vertex: (3+9)/2=6.
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right
Answer:
x + 2y - 5 = 0
Step-by-step explanation:
We can see that , the graph passes through (0,2.5) and (5,0) . Therefore the ,
- x intercept is 5
- y intercept is 2.5
We can use the intercept form of equation as ,
=> x/a + y/b = 1
=> x/5 + y/2.5 = 1
=> x + 2y/5 = 1
=> x + 2y = 5
=> x + 2y -5 = 0 .
This equation can be verified by plotting the graph .[ Refer to attachment ]

Answer:
3/4 or 0.75 decimal
Step-by-step explanation:
Simplify the following:
(2/3)/(8/9)
Hint: | Write (2/3)/(8/9) as a single fraction.
Multiply the numerator by the reciprocal of the denominator, (2/3)/(8/9) = 2/3×9/8:
(2×9)/(3×8)
Hint: | In (2×9)/(3×8), divide 9 in the numerator by 3 in the denominator.
9/3 = (3×3)/3 = 3:
(2×3)/8
Hint: | In (2×3)/8, divide 8 in the denominator by 2 in the numerator.
2/8 = 2/(2×4) = 1/4:
Answer: 3/4
