Answer:
x + 12 = 0
Step-by-step explanation:
Answer:
x = -12
Step-by-step explanation:
1 x 8 = 8
1 x x = 1x
1 x 4 = 4
rewrite expression
8 + 1x + 4 = 0
combine like terms
8 + 4 = 12
1x + 12 = 0
subtract 12 from both sides
12 - 12 = 0
0 - 12 = -12
1x = -12
divide by 1 on both sides to get x by itself
1x/1 = x
-12/1 = -12

Suppose a car gas tank holds 21 gallons of gas. On a trip it uses 2/3 of a tank of gas on a trip. Then it uses 1/3 of what is left in the tank. How many gallons of gas are left in the tank? If u can could u show the work?
9514 1404 393
Answer:
2/9 tank
Step-by-step explanation:
After the first trip, 1 -2/3 = 1/3 of the tank remains.
After the second trip, 1 -1/3 = 2/3 of that remains.
After both trips, (1/3 tank)(2/3) = 2/9 tank remains.

Which property is being demonstrated?
quotient of powers property
power of a product property
product of powers property
power of a quotient property
Answer:
A.
Step-by-step explanation:
We see a fraction. A fraction means a division, and the result of a division is called a quotient. We know we have a quotient.
We have two choices with "quotient."
A. quotient of powers property
D. quotient of powers property
We need to choose A or D.
A. quotient of powers means a division of powers. That is what we see with the fraction. A power in the numerator, and a power in the denominator. We have a division of powers, so it is a quotient of powers.
D. power of a quotient. This is take a fraction which is a quotient, and raise the entire fraction to an exponent. This is not what we have.
Answer: A.
6x + 2(7x – 4) = 92 I T
Answer:
x = 5
Step-by-step explanation:
6x + 2(7x – 4) = 92
simplify:
6x + 14x - 8 = 92
20x = 100
x = 5
Answer:
6x+2(7x−4)=92
Step 1: Simplify both sides of the equation.
6x+2(7x−4)=92
6x+(2)(7x)+(2)(−4)=92(Distribute)
6x+14x+−8=92
(6x+14x)+(−8)=92(Combine Like Terms)
20x+−8=92
20x−8=92
Step 2: Add 8 to both sides.
20x−8+8=92+8
20x=100
Step 3: Divide both sides by 20.
100
20

C'(2, -3)
classify and degree 2x+7
Answer:
Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2
Practice classifying these polynomials by the number of terms:
1. 5y
2. 3x2-3x+1
3. 5y-10
4. 8xy
5. 3x4+x2-5x+9
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
Step-by-step explanation:
Let the function f(x) have the form f(x) = Acos(x-C). To produce a graph that matches the one shown below, what must the value of C be?
Answer: Option B, C = 3.
Step-by-step explanation:
Here we have the function:
f(x) = A*cos(x - C)
A is the amplitude, and we can easily see that the amplitude is 2.
Then:
f(x) = 2*cos(x - C)
We also can see that when x = 0, f(x) ≈ -2
This means that:
cos(0 - C) ≈ -1
Cos(C) ≈ -1
Now we can just evaluate in the different options and see which one is the correct option.
Cos(1) = 0.54
Cos(2) = -0.42
Cos(3) = -0.99
Cos(4) = -0.65
The closer option to -1 is when C = 3, then the correct option is option B.
Answer:
B

1. What is the product of 1/2x - 1/4 and 5x^2+6
show your work
Answer:
Step-by-step explanation:
First you would make the equation
(1/2x - 1/4)(5x^2 + 6)
afterwards you would multiply like normal binomials\
5/2x^3 + 3x - 5/4x^2 - 6/4
Then simplify
5/2x^3 - 5/4x^2 + 3x - 3/2
Remember to put them in order from the most roots to the least.

Can someone give me the answer and explanation
Answer: A
Step-by-step explanation:
The total minus the cost of the eggs leaves you with just the total of the potatoes. Since we know that the total of the potatoes is the product of 5 bags, we can divide the total of the potatoes by 5 to find the cost of each bag of potatoes.
A recipe for beef fajitas uses 5 pounds of beef to make 20 meals. How many pounds of beef are needed to make 80 meals?
Answer: 0.25 pound of beef are needed to make 80 meals.
Step-by-step explanation:
Given : A recipe for beef fajitas uses 5 pounds of beef to make 20 meals.
Then the of beef required for 1 mesal = ( 5 pounds) ÷ 20
= [tex]\dfrac{5}{20}[/tex] pound
[tex]=\dfrac{1}{4} [\text{Divide numerator and denominator}][/tex]
=0.25 pound
Hence, 0.25 pound of beef are needed to make 80 meals.

Annie has two equal-sized pies. She served 5/8
of the first one and 1.3 of the second one. What fraction shows the total amount of pie left?
9514 1404 393
Answer:
25/24
Step-by-step explanation:
Annie has 1 - 5/8 = 3/8 of the first pie left.
Annie has 1 - 1/3 = 2/3 of the second pie left.
The total fraction of pie left is ...
3/8 + 2/3 = (3·3 +8·2)/(8·3) = 25/24 . . . of a pie left

Step-by-step explanation:
Chau and Yoko each opened a savings account today. Chau opened his account with a starting amount of $460, and he is going to put in $60 per month. Yoko opened her account with a starting amount of $530, and she is going to put in $50 per month.
Let x be the number of months after today.
(a) For each account, write an expression for the amount of money in the account after x months.
Amount of money in Chau's account (In dollars) =
Amount of money in Yoko's account (in dollars) =
(b) Write an equation to show when the two accounts would have the same amount of money.
Answer:
A1-60x+460
A2-50x+530
B-60x7+460
50x7+530
Step-by-step explanation:
A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.
B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.
