Answer:
B. (2,8), because both equations intersect at this point
Answer:
1. n + 4
2. x(n) + 4
Step-by-step explanation:
The two solutions were arrived at based on the following :
1. The total number of fruit, irrespective of the kind or type.
In this case, let the number of fruit be n.
Adding 4 peaches gives: n + 4 fruits.
2. The second expression takes into account the peaches only.
This times around, let the total fruits be n.
The number of peaches in the basket can be given as a fraction. Let the fraction be <em>x</em>
The number of peaches is the fraction of peaches multiplied by the total number of fruit like this: <em>x</em>n
However, 4 peaches are added, therefore, the total number will be <em>x</em>n+4
This figure denotes the number of peaches in the basket.
Lets be a price of the calculator - $ a
then , after using the coupon, you need to pay $(a-18)
and after using 15% discount , you need to pay (1-0.15)a=0.85a
then, if
(a-18) will be more than 0.85a, you should prefer 0.15 % discount, because it will be cheaper,
a-18> 0.85a
a-0.85a>18
0.15a > 18
a>120, that means that if the price of the calculator more than $120, 15% discount is better,
but if the price of the calculator is less than $120, you should choose $ 18 coupon.
for example, we have the price of the calculator $100
100-18=82,
100*0.85 =85, coupon is better.
If the price of the calculator $200
200-18=182,
200*0.85=170, so 15% discount is better
if price of the calculator is $120,
120-18=102
120*0.85=102,
it will not matter, what you are going to use, because you are going to pay the same amount of money

Yes, for any value of "b" the value of the first expression is greater than the value of the second expression.
Step-by-step explanation:
Substitute the given values of "b" into each expression and evaluate.
- For the first expression , you get:
If →
If →
If →
- For the second expression , you get:
If →
If →
If →
You can observe that for any value of "b" the value of the first expression is greater than the value of the second expression.
