Answer: a) Cost(x) = $9.50 + $15*x
b) $84.50
Step-by-step explanation:
a) If x is the number of members in the family, we can model this situation with a linear equation, where x is the variable.
We have:
A fixed $9.50 (this does not depend on the number of members in the family)
and $15 for each member, so the equation that represents this is:
Cost(x) = $9.50 + $15*x
b) now we have x = 5, then:
Cost(5) = $9.50 + $15*5 = $84.50
Answer:
a. y = 9.50 + 15a
b. total cost(y) = 84.5
Step-by-step explanation:
Brandon decided to take his family to a water park to celebrate the end of the school year.
The cost for parking is $ 9.50 which is a flat rate and compulsory rate for parked cars. The cost for each person is $15 .
a. The linear equation can be expressed below. The variable required in the linear equation will be the number of people that entered the water park(a) and the total cost (y)
let
a = number of person for the entire day
total cost = y
y = 9.50 + 15a
b. To find the cost for a whole family of 5 member can be calculated below.
Using the linear equation
total cost = 9.50 + 15a
total cost = 9.50 + 15(5)
total cost = 9.50 + 75
total cost(y)= 84.5

A parabola has a vertex at (-1,0) and opens down. What is the equation of the parabola?
Answer:
y = - (x + 1)²
Step-by-step explanation:
Vertex form of a parabola is given by,
y = -(x - h)² + k
Where (h, k) is the ordered pair representing vertex.
(-) sign denotes that the parabola is opening downwards.
If the coordinates of the given parabola is (-1, 0)
Equation of the parabola will be,
y = - (x + 1)² + 0
y = - (x + 1)²
Therefore, equation of the parabola will be, y = - (x + 1)²

What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Select all the correct answers. Aisle 2 of a furniture store stocks 4-legged chairs, 4-legged tables, and 3-legged stools. If there are t tables, c chairs, and s stools, which expressions show the total number of furniture legs in aisle 2?
Answer: T = 4c + 4t + 3s
Step-by-step explanation:
Stocks contains:
4-legged chairs
4-legged tables
3-legged stools
So, 1 chair has legs = 4
So, c chairs has legs = 4c
1 table has legs = 4
So, t tables has legs = 4t
1 stool has legs = 3
So, s stools has legs = 3s
Let T denotes the total no. of legs
So, the total number of furniture legs in aisle 2 :
T = 4c + 4t + 3s

c. x = 3-3301 3+33
d x-3-3-301-3+3.3
Answer:
x = - 12, x = 6
Step-by-step explanation:
Given
(x + 3)² - 81 = 0 ( add 81 to both sides )
(x + 3)² = 81 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{81}[/tex] = ± 9 ( subtract 3 from both sides )
x = - 3 ± 9
Thus
x = - 3 - 9 = - 12
x = - 3 + 9 = 6

Answer:
2 pieces, 30ft each

rope : 60ft long
we are trying to figure out how many equal pieces we can cut the rope into with the length of each piece to be the greatest possible integer:
if jason wants the length of rope to be the longest than the answer is 2, if he divides the length of 60 by 2, each piece will be 30 feet long. If he divides the rope by any number larger, each piece will be shorter than 30 feet, and he wants the piece to be the largest possible length.

the sum of two numbers is 90 .the larger number is 14 more than 3 times the smaller number.
Answer:
The numbers are 19 and 71.
Step-by-step explanation:
Let x and y represent the two numbers. Then x + y = 90.
Also, if we assume that the larger number is y, then y = 3x + 14.
We must solve this system of linear equations. Since we already have the result of solution for y (y = 3x + 14), let's use the substitution method to find the solution:
x + y = 90 becomes x + 3x + 14 = 90, or:
4x = 76. Thus, x = 76/4, or 19. If x = 19, then y = 3(19) + 14, or y = 71.
The numbers are 19 and 71.
Note that these add up to 90, as they must, and that 71 is 14 more than 3 times 19.
