Answer:
8
Step-by-step explanation:
Answer: The Answer Is C.
Step-by-step explanation:
When you divide each of them you will notice that C costs the least.
For choice A when you 5 by 3.25 you will get 0.65.
For choice B when you divide 8 by 6.10 you will get 0.7625
For choice C when you divide 12 by 7 you will get 0.5833.....
For choice D when you divide 10 by 6.44 you will get 0.644.
So when you look at the results you will see that choice C is the best deal.
Answer:
formula: y-y1 = m(x-x1)
Step-by-step explanation:
General:
1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m
2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1
3. solve the problem
Example:
line 1:
1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1
2. y-6 = -1(x-(-4) or y-6 = -1(x+4)
3. y-6 = -1x-4
4. y = -1x-2
3. the gradient equals: y = -1x-2
Hope this helps :) Let me know if you need a better example
Answer:
x= 16 ounces
Step-by-step explanation:
Apple juice: Orange Juice
8:4 = 2:1
For every 2 parts of Apple Juice, 1 part of Orange Juice is used.
So 32 ounces would be equivalent to 2 parts..
This means the proportion of Orange Juice needed would be 16 ounces.
Answer:
1) 
2) 
3) 
Step-by-step explanation:
To evaluate or simplify expressions with exponents, we use exponent rules.
1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2. When we multiply terms with the same bases, we add exponents.
3. When we divide terms with the same bases, we subtract exponents.
4. When we have a base to the exponent of 0, it is 1.
5. A negative exponent creates a fraction.
6. When we raise an exponent to an exponent, we multiply exponents.
7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules to simplify.
Problems:
1) 
n^-6 has a negative exponent and should be moved to the denominator while p^0 is equal to 1
2) 
Divide each base by subtracting exponents. a^4-1 = a^3 and b^-3--2=b^-1. B has a negative exponent so move it into the denominator.
3) 
Simplify inside the parenthesis first by adding exponents of same bases x^-2+3 = x. Then apply the outside exponent using power to a power rule and negative exponent rule.
