Answer:
x = 1/3 or -2
Step-by-step explanation:
2x^2 + 7x - 2 = - x^2 + 2x
3x^2 + 5x - 2 = 0 (use factoring)
(3x − 1)(x + 2) = 0
3x - 1 = 0 OR x + 2 = 0
3x = 1 x = - 2
x = 1/3

Answer:</h2>
<em><u>Percent value of A with respect to Percent value of B is,</u></em>

<h2>
Step-by-step explanation:</h2>
In the question,
Let us say the value of the Baseball card A and B initially is = 100x
So, for Baseball card A in first 5 years percent increase = 20%
So,
Value after 5 years = 100x + 20% of 100x = 120x
<u>After 5 more years,</u>
Percent decrease = 50%
So,
<u>Value at the end of 10 years = 120x - 50% of 120x = 60x</u>
Now,
For Baseball card B, Percent increase in 10 years = 100%
So,
<u>Value of card B = 100x + 100% of 100x = 200x</u>
So,
<em><u>Percent value of A with respect to Percent value of B is,</u></em>

Answer: 99.5
Step-by-step explanation:
398 ÷ 4
Answer:
Since there is one value of y for every value of x in (−4,8),(−2,4),(0,1),(2,4), ( 4,8), this relation is a function. The relation is a function.
8x + 4 = 5x - 11
Subtract 5x from both sides:
3x + 4 = -11
Subtract 4 from both sides:
3x = -15
Divide both sides by 3:
x = -5
Answer : x = -5
