Step-by-step explanation:
[tex]7y = 8x - 14[/tex]
get rid of the Y and put in a 6
[tex]7(6) = 8x - 14[/tex]
[tex]7 \times 6 = 42[/tex]
[tex]42 = 8x - 14[/tex]
we need to get rid of the negative 14 so its only 8x.
to get rid of 14 on one side you add it to the other
[tex]42 + 14 = 56[/tex]
[tex]56 = 8x[/tex]
to get X by itself have to divide 8 by both sides
[tex]56 + \div 8 = 7[/tex]
[tex]8x \div 8 = x[/tex]
[tex]x = 7[/tex]
The product of two negative rational numbers is
zero.
Answer:
False
Step-by-step explanation:
This statement is false. If you multiply two negative rational numbers together, say -8 and -7, you get 56. In fact, you cannot multiply any two negative rational numbers and get zero.

Laura is planning a party for her son. She has $50 dollars remaining in her budget and wants to provide one party favor per person to at least 10 guests. She found some miniature stuffed animals for $6.00 each and some toy trucks for $4.00 each. Which system of inequalities represents this situation, where x is the number of stuffed animals and y is the number of toy trucks?
Answer:
The system of inequalities that represents this situation is:
x+y≥10
6x+4y≤50
Step-by-step explanation:
As the statement says that Laura wants to provide one party favor per person to at least 10 guests, the first inequality would indicate that the number of stuffed animals plus the number of toy trucks should be equal or greater than 10:
x+y≥10
Also, the statement indicates that miniature stuffed animals cost $6.00 each and the toy trucks cost $4.00 each and that Laura has $50. From this, you would have an inequality that indicates that 6 for the number of miniature stuffed animals and 4 for the number of toy trucks would be equal or less than 50:
6x+4y≤50
The answer is that the system of inequalities that represents this situation is:
x+y≥10
6x+4y≤50
Laney bought 1 2/3 pounds of grapes. She also
bought bananas that were
2 1/4 times the weight of
the grapes. How much did the bananas weigh? helppppp
Answer:
The bananas weigh 3 3/4 pounds.
Answer: 3 3/4
Step-by-step explanation:
All we have to do is multiply the weight of the grapes by 2 1/4.
= 1 2/3 x 2 1/4
= 5/3 x 9/4
= 45/12
= 3 9/12
= 3 3/4

Step-by-step explanation:
we know that xoy is 90° on every quadrant
also the origine where p start is a little bit down from x axis so A is the right answer as it is the most logical point
D and C cant be P because are a very large angle of rotation than 105.B is smaller then 105 rotation of p so A is the right one.

Which expressions are equivalent to 7^-2•7^6
Choose two answers
A.7^2/7^-2
B.7^6/7^-2
C.7^-12
D.(7^2)^2
===========================================
Explanation:
The expression 7^(-2)*7^6 simplifies to 7^4
We use the rule a^b*a^c = a^(b+c). In this case a = 7, b = -2, c = 6
In short, we add the exponents.
----------
In choice A, we use the rule (a^b)/(a^c) = a^(b-c) where we're now subtracting the exponents.
Here we have the exponents subtract to b-c = 2-(-2) = 2+2 = 4. This shows that (7^2)/(7^(-2)) = 7^4
This is why choice A is one equivalent expression.
----------
Choice D is the other equivalent expression since
(7^2)^2 = 7^(2*2) = 7^4
The rule used here is (a^b)^c = a^(b*c). We're multiplying exponents now.
-----------
Alternatively you can find that 7^(-2)*7^6 = 2401 through use of a calculator.
Then go through each answer choice to see which also produce a result of 2401.

Answer:
The tanks by volume per fish from least to greatest:
Tank C, Tank A, Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Order the tanks by volume per fish from least to greatest.
Tank A holds 40 L and 5 fish.
= 40L/5 fishes
= 8 volume per fish
Tank B holds 100 L and 12 fish
= 100L/12 fishes
= 8.3333333333 volume per fish
Tank C holds 180 L and 23 fish.
= 180L /23 fish
= 7.8260869565 volume per fish
The tanks by volume per fish from least to greatest
Tank C, Tank A, Tank B
You make an initial deposit of $2,500 in an account that offers 6% simple interest per year. How much will be in the account after 4 years?
Enter the correct answer in the box.
Answer:
3100
Step-by-step explanation:
3100
The amount of money in the account that he has after 4 years will be $3100.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
You make a $2,500 initial deposit into an account that pays 6% simple interest per year.
Then the amount of money in the account that he has after 4 years will be given as,
A = 2500 + (2500 x 6 x 4)/100
A = 2500 + 600
A = $3100
The amount of money in the account that he has after 4 years will be $3100.

The parabola intersects the directrix.
Answer:
A parabola is the set of all points equidistant from the directrix and focus.
The line of symmetry intersects the focus and directrix
The line of symmetry and the directrix are perpendicular
Step-by-step explanation:
A parabola is the set of all points in a plane that are equidistant from a fixed point (focus) and a line (directrix).
The fixed line of a parabola is known as the directrix of the parabola.
The line of symmetry is a line that passes through the focus and is perpendicular to the directrix. The line of symmetry divides the parabola.
