Step-by-step explanation:
-9x + 1 = -x + 17
collect like terms
-9x + x = 17-1
-8x = 16
divide both sides by -8
-8x/-8 = 16/8
x = 2
<span>The expression b^2-4ac is called the discriminant. If it is zero, or positive and a perfect square (like 4, 9, 25, 36, etc), the solutions to the quadratic equation will be rational numbers and factoring will work.
On the other hand, if the discriminant is positive but not a perfect square, the solutions will be irrational, and if it is negative, there are no real solutions. In either of those cases, the quadratic expression cannot be factored.
In the equation 2x^2+7x+3=0, the discriminant is b^2-4ac = 7^2 - 4*2*3= 49-24 = 25 = 5^2
That means that the solutions can be found by factoring.

Answer:
<h2>$108.59 </h2>
Step-by-step explanation:
The dime which is worth 0.10 U.S. dollar, is a ten-cent coin, one-tenth of a United States dollar
the value is 0.1
Now in rounding up of numbers the dime is located one decimal place away i.e 0.5 in the number given in the problem statement
to round up to the nearest dime we have to consider the next number to the dime if this number is greater than 5 we will round up if it is less than five we can not perform any rounding up operation
hence the greatest amount of money is
since the number next to 5 is 9 and 9 is greater than 5 we will round up from 5 to 6
This makes 108.59 the greatest amount of money that rounds to $108.60
98.86-85.15= 13.71 This is the answer to the problem. It's really easy. U just subtract and that's it.
Answer:
1.0282
Step-by-step explanation:
The multiplier for a increase of a% is 1 + a/100.
The multiplier for a decrease of b% is 1 - b/100.
Decrease of 3% followed by a 6% increase:
Calculate each multiplier, and then multiply then:
Decrease 3%: 1 - (3)/100 = 0.97
Increase 6%: 1 + (6)/100 = 1.06
0.97*1.06 = 1.0282
The answer is 1.0282
