What is the length of segment AB ?
Answer:
[tex]\sqrt{74}[/tex]
Step-by-step explanation:
Distance between two points
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\textsf{let}\:(x_1,y_1)=(2,-6)[/tex]

[tex]d=\textsf{length of segment AB}[/tex]
Substituting points into the distance formula and solving for d:

Penny needs 12 ounces of a snack mix that is made up of chocolate and almonds. The chocolate costs $3.50 per ounce and almonds cost $4.50 per ounce. Penny has $50 to spend and plans to spend it all.
Let x = the amount of chocolate
Let y = the amount of almonds
Determine which equations you would use to form a system of equations for this scenario.
Question 18 options:
x + y = 50
x + y = 12
3.5x + 4.5y = 50
3.5y + 4.5x = 50
3.5x + 4.5y = 12
3.5y + 4.5x = 12
Answer:
Total ounces should be 12
and hence
x + y = 12
and total money to spend is 50, hence
3.5x + 4.5y = 50
Therefore, these are the two ✌️ equations you should use
x + y = 12
3.5x + 4.5y = 50

Given phrase - 66 less than twice Greg's age
In the given phrase, "twice" means "double", which means "2 times".
⇒ 66 less than 2(Greg's age)In the given phrase, "less than" means "subtraction in reverse form".
⇒ 66 - 2(Greg's age)Reversing the expression, we get:
⇒ 2(Greg's age) - 66The question has stated that "Greg's age" will be represented as "g". Let's substitute "Greg's age" as "g". Then,
⇒ 2(Greg's age) - 66⇒ 2(g) - 66 = 2g - 66Therefore, the expression that represents the phrase is 2g - 66.

y = 2x − 5
y = -6x + 3
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.
Part B: Check your work. Verify your solution and show your work.
Part C: If the two equations are graphed, what does your solution mean?
Answer:
Part A
Solve by substitution.
Given equations:
y = 2x − 5y = -6x + 3⇒ 2x - 5 = -6x + 3
⇒ 2x - 5 + 5 = -6x + 3 + 5
⇒ 2x = -6x + 8
⇒ 2x + 6x = -6x + 8 + 6x
⇒ 8x = 8
⇒ 8x ÷ 8 = 8 ÷ 8
⇒ x = 1
To find y, substitute the found value of x into one of the equations:
⇒ y = 2(1) - 5
⇒ y = 2 - 5
⇒ y = -3
Therefore, the solution is (1, -3)
Part B
Substituting x = 1 into the equations:
y = 2x − 5
⇒ y = 2(1) − 5
⇒ y = 2 − 5
⇒ y = -3
y = -6x + 3
⇒ y = -6(1) + 3
⇒ y = -6 + 3
⇒ y = -3
When x = 1, both equations return a y-value of -3. Therefore, the solution is verified.
Part C
If the two equations are graphed, the solution will be the point of intersection.
Estimate the cost of painting a concrete patio if it is a 14 foot by 8 foot rectangle and a quart of paint that covers 47 square feet costs $10.99
Answer:
Estimate the cost of painting a concrete patio if it is a 14 foot by 8 foot rectangle is $25.76
Step-by-step explanation:
Underline is the given:
a concrete patio if it is a 14 foot by 8 foot rectangle
area of the concrete patio: 14ft x 8ft = 112
quart of paint that covers 47 square feet costs $10.99
the cost per foot: 10.99 / 47 = $0.23
the area is 112 so multiply it by cost per foot:
112 x $0.23 = $25.76
The estimated cost of painting the concrete patio is approximately $32.97.
To estimate the cost of painting a concrete patio, we first need to calculate the total area of the patio. The patio is a rectangle with dimensions 14 feet by 8 feet, so the total area is 14 feet × 8 feet = 112 square feet.
Next, we determine how many quarts of paint are needed to cover the patio. Since each quart covers 47 square feet, we divide the total area by 47:
112 square feet ÷ 47 square feet/quart ≈ 2.38 quarts
Since we can't purchase a fraction of a quart, we'll round up to 3 quarts.
Finally, with each quart costing $10.99, the estimated cost of painting the concrete patio is:
3 quarts × $10.99/quart = $32.97
So, the estimated cost of painting the concrete patio is approximately $32.97.

f(x) = (x − 1)2(x + 1)(x − 3)
Step-by-step explanation:
Look at where the red line crosses/ touches the x-axis. This will give you the zeros.
It crosses at -1, touches at 1, and crosses again at 3
This means the zeros are -1, 1 and 3
Now, you need to have (x+1) (x-3) and (x-1) as factors.
Therefore, the answer is f(x) = (x − 1)2(x + 1)(x − 3).

Jocelyn is comparing the prices of wedding cakes. Store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge. If Jocelyn wants a cake with 150 servings, how much more money will it cost to purchase the cake from Store B?
The Jocelyn needs to pay $87.5 if Jocelyn order cakes from store B if store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the total cost is $x if Jocelyn purchase cake from store A:
x = 1.50×150 + 25
x = 225+25 = $250
Let's suppose the total cost is $y if Jocelyn purchase cake from store B:
y = 2.25×150
y = $337.5
Difference between total cost = 337.5 – 250 = $87.5
Thus, the Jocelyn needs to pay $87.5 if Jocelyn order cakes from store B if store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge.

Green: (2/11) * (1/10)
Yellow: (2/5) * (1/3)

Step-by-step explanation:
Green:
>> Maria has 11 letters in her bag, and 2 of them are B's.
>> At first, the chance of drawing a B is 2 out of 11: 2/11.
>> Let's assume that everything goes according to plan, and she actually draws a B.
>> Then she has 10 letters, and only one of them is B (she already has the other one).
>> That means that the chance of drawing that B is 1 out of 10: 1/10.
>> Thus, (2/11)*(1/10).
Yellow:
>> There are 11 + 13 + 16 = 40 items in the closet.
>> The probability of selecting a prop is 16/40 = 2/5 (there are 16 props and 40 items).
>> That means that there are 40-1=39 items left.
>> Therefore, the probability of selecting a costume is 13/39 = 1/3 (as there are 13 costumes and 39 items).
>> The answer is (2/5) * (1/3).
Purple:
>> There are 6+8+6=20 jellybeans.
>> At first, Hannah grabs an orange candy (there are 6 of them): 6/20 = 3/10.
>> Then there are 19 candies left.
>> Then she grabs a pink one (there are 6 of them): 6/19.
>> The answer is (3/10)*(6/19).

>> There are 52 cards in a standard deck, 13 clubs, 13 spades, 13 hearts, 13 diamonds.
>> The 1st is a spade: 13/52 = 1/4.
