5. The blue one is y >= 5x - 7
and green is y >= -0.65x + 3
6. y <= (4/5)x
y >= -(5/4)x
<u>Answer</u>
9+√14
<u>Explanation</u>
To Rationalize the denominator of 5-√7/9-√14.
To rationalize this we multiply both the denominator and denominator by the conjugate of the denominator.
The denominator is 9-√14 and its conjugate is (9+√14).
(5-√7)/(9-√14) = (5-√7)(9+√14)/(9-√14)(9+√14)
= (5-√7)(9+√14)/(9²-14)
= (45 + 5√14 - 9√7 - √98)/(81-14)
= (45 + 5√14 - 9√7 - √98)/67
= (45 + 5√14 - 9√7 - 7√2)67
This is the rationalized expression.
The denominator is (9-√14) and its conjugate is (9+√14).
Answer:
1 is the value of x
Step-by-step explanation:
...............
Answer:
x = 17/2
Step-by-step explanation:
x-3 x+8
------ = ------------
2 6
Using cross products
(x-3) *6 = 2 (x+8)
Distribute
6x - 18 = 2x+16
Subtract 2x from each side
6x-2x-18 = 2x-2x+16
4x-18 = 16
Add 18 to each side
4x-18+18 = 16+18
4x = 34
Divide each side by 4
4x/4 = 34/4
x = 17/2
Answer:
