Oth John's parents and Marco's parents decide to start a college fund for their children. The expressions below represent the value of each college fund after w weeks. John's College Fund: 43 w + 1814 12 Marco's College Fund: 25 w + 1744
Answers
Answer:
Step-by-step explanation:
The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.
let the total fund funds be y
and the number of weeks be w
For John's fund the expression is
y=45w+1814------1
Marco's College Fund
y=25 w+1744---------2
equating 1 and 2 we have
45w+1814=25w+1744
45w-25w=1744-1814
20w=-70
divide both sides by 20 we have
w=-70/20
w=-3.5
this means that in 3 and half weeks the two funds will have the same amount in them

Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.
Rotation is a type of transformation that turns an object about a fixed point. Rotation preserves the shape and size of the image. The rotation of point X(x, y) 180° about the origin gives a new point X'(-x, -y) i.e. both the x and y coordinate is negated.
Kayla was driving from Philadelphia to Florida, trying to remain at a constant speed as much as possible after she reached the highway. She travelled 139.5 miles after an hour and a half and then 395 miles after 5 hours. Which represents Kayla's speed (rate of change)?
Answers
Answer:
Step-by-step explanation:
Speed = change in distance/change in time
S= Δd/Δt
let d1 = 139.5miles
d2 = 395miles
t1 = 1.5 hrs
t2 = 5hrs
Δd = d2-d1
Δd = 395-139.5
Δd = 255.5miles
Δt = 5-1.5
Δt = 3.5hrs
Speed = 255.5/3.5
Speed = 73miles/hr
Hence Kayla's speed is 73miles/hour
Identify the independent and dependent variables. Then write a rule in function notation for the situation, letting x represent the independent variable.
A concert ticket costs $60.
Answers
Answer:
independent: number of tickets purchased;
dependent: total cost;
rule: f(x) = 60x
Step-by-step explanation:
The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.
The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.
The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that when an object of mass m kilogram is attached to the other end of the spring, the spring stretches to a length of / centimeters as shown in the equation l = 24 +3.4m.
The mass will be calculated as below,
73 = 24 + 3.4m
49 = 3.4m
Divide by 3.4 into both sides
14.4 = m

Use the slope formula to find the slope between the given two points?

Answers
Answer:
4/3
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
(9-1)/(8-2)
4/3
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
(2,1) (8,9)
The formula that you would use is:
[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]
So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]
and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]
When we insert these numbers into the equation, we get:
[tex]\frac{9-1}{8-2}[/tex]
When we solve that we get:
[tex]\frac{8}{6}[/tex]
Now we simplify it by dividing both the numerator and denominator by 2, which would give us:
[tex]\frac{4}{3}[/tex]

Answers
Answer:
[tex]x=\frac{576}{11}[/tex]
Step-by-step explanation:
13x - 12x + 45 * 12 = 14 - 12x - 10.5
Multiply first
13x - 12x + 540 = 14 - 12x - 50
Combine like terms
x + 540 = 12x - 36
Subtract x from both sides
540 = 11x - 36
Add -36 to both sides
576 = 11x
Divide both sides by 11
[tex]x=\frac{576}{11}[/tex]
