What is the solution to f(x) = g(x)?The solution to f(x) = g(x) is the value(s) of x that satisfy the equation. In other words, it is the value(s) of x that make f(x) equal to g(x).
The only problem here is determining which graph is correct:
f(x) is the same on both graphs;
g(x) = 2 |x + 2| is the absolute value graph of lxl stretched vertically two units to the left;
the "vertex" of lxl is (0, 0);
consequently, the first graph is correct; and the x values for the solutions are x = -2 and x = 0.

Answer:
y=-1/2x-8
Step-by-step explanation:
The polynomial x^4+px^3+qx^2+rx+6 is exactly divisible by each of (x-1), (x-2) and (x-3).
Find the values of p, q and r.
The remainder theorem says that a polynomial f(x) has a remainder of f(c) upon getting divided by x - c. So if
f(x) = x⁴ + p x³ + q x² + r x + 6
is divisible by x - 1, x - 2, and x - 3, then we have
f (1) = 7 + p + q + r = 0
f (2) = 22 + 8p + 4q + 2r = 0
f (3) = 87 + 27p + 9q + 3r = 0
Solve the system for p, q, r. You can eliminate r by substituting the first equation into the other two:
p + q + r = -7
8p + 4q + 2r = -22 → 6p + 2q - 14 = -22 → 3p + q = -4
27p + 9q + 3r = -87 → 24p + 6q - 21 = -87 → 4p + q = -11
Eliminate q by adding (-1) times the first equation to the second one, then solve for p :
- (3p + q) + (4p + q) = - (-4) + (-11)
-3p - q + 4p + q = 4 - 11
p = -7
Solve for q :
3p + q = -4 → 3 (-7) + q = -4 → q = 17
Solve for r :
p + q + r = -7 → -7 + 17 + r = -7 → r = -17
Using the elimination method and showing all of your steps. Solve the following System of Equations. Make sure to write your answer as an order pair.

Answer:
[tex]\huge\boxed{\sf Star = 14}[/tex]
Step-by-step explanation:
Let snowman be x , star be y and shopping bag be z.
So, the given equations are:
1) x + y = 20 (Eq. 1)
2) z = x + x
z = 2x (Eq. 2)
3) z + x = 18 (Eq. 3)
Put Eq. (2) in Eq. (3)
2x + x = 18
3x = 18
Divide both sides by 3
x = 18 / 3
x = snowman = 6
Now, Put x in (Eq. 1)
6 + y = 20
Subtract 6 to both sides
y = 20 - 6
y = 14
So,
Star = 14

Martin is seating people in the cars of a roller coaster. Each car can seat 8 people. Six of the roller coaster cars are yellow and nine of the roller coaster cars are green. People will be randomly seated in the roller coaster cars. What is the probability that the first person will be seated in a yellow roller coaster car?
Answer:
The probability is 2/5
Step-by-step explanation:
Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car
The number of cars to select from is 6 + 9 = 15 cars
The number of yellow cars is 6
So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5

Alfred and Larissa have $21.00 each to spend at a book fair, where all students receive a 35% discount. They both want to purchase a copy of the same book, which normally sells for $28.50 plus 10% sales tax. To check if he has enough to purchase the book, Alfred takes 35% of $28.50 and subtracts that amount from the normal price. He takes 10% of the discounted selling price and adds it back to find the purchase amount. Larissa takes 65% of the normal purchase price and then computes 110% of the reduced price. Is Alfred correct? Is Larissa correct? Do they have enough money to purchase the book? Explain your answer using complete sentences and show your work.
Answer: See explanation
Step-by-step explanation:
The normal cost of the book plus the sales tax will be:
= $28.50 + ($28.50 × 10%)
= $28.50 + ($28.50 × 0.1)
= $28.50 + $2.85
= $31.35
Since there's a discount of 35%, the amount they'll have to pay will be:
= $31.35 - ($31.35 × 35%)
= $31.35 - ($31.35 × 0.35)
= $31.35 - $10.9725
= $20.3775
They do not have enough money to make the purchase.
Alfred takes 35% of $28.50 and subtracts that amount from the normal price. Alfred's calculation is shown below:
= $28.50 - (35% of $28.50)
= $28.50 - (0.35 × $28.50)
= $28.50 - $9.975
= $18.525
He takes 10% of the discounted selling price and adds it back to find the purchase amount. This will be:
= $18.525 + (10% × $18.525)
= $18.525 + $1.8525
= $20.3775
Alfred is correct
Larissa takes 65% of the normal purchase price and then computes 110% of the reduced price. This will be:
= 65% × $28.50
= 0.65 × $28.50
= $18.525
= 110% × $18.525
= 1.1 × $18.525
= $20.3775
Larisa is also correct

Jorge has a Total of 67 coins. All of which are dimes and nickels. The total value of the dimes and nickels i $5.40. Find the number of each type of coin.
Answer:
There are 41 dimes and 26 nickels.
Step-by-step explanation:
From the information given, you know that you have 67 coins which would be:
x+y=67
Also, you now that the value of each coin is:
dimes= $0.10
nickels=$0.05
With this you can say that the number of dimes for its value plus the number of nickels for its value is equal to $5.40:
0.10x+0.05y=5.40
You will have the following equations:
x+y=67 (1)
0.10x+0.05y=5.40 (2), where:
x are the number of dimes
y are the number of nickels
First, you can solve for x in (1):
x=67-y
Then, you can replace (3) in (2):
0.10(67-y)+0.05y=5.40
6.7-0.10y+0.05y=5.40
1.3=0.05y
y=1.3/0.05
y=26
Now, you can replace the value of y in (3) to find x:
x=67-y
x=67-26
x=41
According to this, the answer is that there are 41 dimes and 26 nickels.

Length of a rectangle swimming pool is 50 yards and the width of the pool is 60 yards what is the approximate length of the diagonal of pool
Answer:
Approximately 78 yards
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid because the length and width step different in yards. After sketching a cuboid, length= 60 yards, width= 50 yards, then draw a diagonal across the upper rectangle of the cuboid, to get the diagonal, use Pythagoras theorem, Hypotenuse²= opposite²+adjacent²;. x²=60²+50²=3600+2500=6100 ;.
x²=6100 therefore X=√6100 =78.1024 yards, but approximately 78yards, since the question instructed that answer should be approximated.
How can we use ratios and proportional relationships to help us in our daily lives?
Answer:
In cooking (recipes).
Step-by-step explanation:
If the serving size for a recipe is not adequate for the number of people you are serving, you will have to convert the amounts(measurements) of the ingredients to suit your needs. You will do this by first creating a ratio defining the relationship between the serving size of the given recipe to the number of people needed to be served. For example, if a recipe serves 4 people, and you need to serve 8, your ratio would simplify to 1/2. This means you must proportionally relate this ratio to the individual amounts of each ingredient.

Volume of a Cylinder: V = πr²hStep-by-step explanation:
Step 1: Define
Radius r = 3 in
Height h = 8 in
Step 2: Find Volume V
Substitute [VC]: V = π(3 in)²(8 in)Exponents: V = π(9 in²)(8 in)Multiply: V = 72π in³Multiply: V = 226.195 in³Step 3: Find Water
2/3 of vase should be filled with H₂O.

We know the formula for the volume of a cylinder is V=πr^2has given.
That said, we can plug our values in.
V=π3^2(8)
Simplify.
V=π9*8
V=72π
It needs 72π cubic inches of water.
