Answer:
y = 40 + 0.12x
y = 25 + 0.15x
Step-by-step explanation:
Hey Dylan! We're gonna use variable x to represent number of messages sent.
The $40 & $25 dollar payments won't be changed, so they can't have a variable applied to them.
Since it's 12 or 15 cents per text, that's where we wanna put the x.
Since both equations are equal to y, we can set them equal to each other.
40 + 0.12x = 25 + 0.15x
15 = 0.03x
x = 500 messages
Hope this helps! :)

Which of the following relations is a function?
a
{(1, 1), (1, 2), (1, 3)}
b
{(0, 0), (0, 1), (1, 2)}
c
{(2,0), (3, 2), (5, 2)}
d
{(3, 1), (4, 1), (3, 2)}
Answer:
C is a function
Step-by-step explanation:
For every input in a relation, there should only exist one unique output. For example, in option A, the input 1 has 3 outputs which does not make it a function since they all have to be unique. Additionally, B and D aren't functions for the same reasons. Therefore, C is a function.

Which function represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0)?
A) f(x) = - 7(x – 3) (x + 4)
B) f(x) = -6(x + 3) (x – 4)
C) f(x) = 8 (x-3) (x+4)
D) f(x) = 2 (x+3) (x – 4)
The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0). Option C is correct.
What is a function, exactly?A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
The general parabola equation is as follows: y=p (x-h)²+k or x=p(y-k)²+h, with (h,k) indicating the vertex.
The equation of the parabola is;
y=p (x-3)²+0
y=p(y-0)²+ (-4)
On combining both the equations;
f(x) = 8 (x-3) (x+4)
The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0).
Hence,option C is correct.

1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

The surface area of a soccer ball is 254.5 in?.
What is the radius to the tenths' place?
Answer:
4.5 inches
Step-by-step explanation:
Use the formula for the surface area of a sphere, SA = 4[tex]\pi[/tex]r²
Plug in the surface area and solve for r, the radius:
SA = 4[tex]\pi[/tex]r²
254.5 = [tex]\pi[/tex]r²
20.25 = r²
4.5 = r
So, the radius is approximately 4.5 inches
Two stores each have the same number of lawn mowers for sale. The lawn mowers at Store A have a median price of $150. The lawn mowers at Store B have a median price of $200.
What can best be inferred from this data?
A. Store A has more expensive lawn mowers.
B. Store B has more expensive lawn mowers.
C. The stores have the same amount of expensive lawn mowers.
D. It is impossible to say which store has more expensive lawn mowers.
Answer:
Store B has more expensive lawn mowers.
Step-by-step explanation:
The median price is the price in the middle of the possible prices which means that if you double the median price you will get about what the highest price can be.
What can be inferred from the data is store B has more expensive lawn mowers.
What does median mean?Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order. Median is a measure of central tendency. For example 3 is the median in this dataset: 1, 3, 6

Last weekend, Abigail collected 7 times as many trading cards as Trey. Together, they collected 40 trading cards. How many trading cards did Abigail collect?
Answer: 35 trading cards
Step-by-step explanation:
Assume the trading cards collected by Trey is x.
That means that the number of trading cards collected by Abigail is 7x.
Relevant expression is:
7x + x = 40
8x = 40
x = 40/8
x = 5 trading cards
This means that Trey collected 5 trading cards
Abigail collected 7 times that figure so Abigail collected:
= 7 * 5
= 35 trading cards

How do I solve these problems?
Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

Shin used a doubling and halving strategy to solve 25 times 68. Fill in the blanks in the arrays and the equations to represent her work
Answer:
[tex]25 * 68 = 1700[/tex]
Step-by-step explanation:
Given
[tex]25 * 68[/tex]
Required
Fill the array using doubling and halving
Question is incomplete, as the array is not given.
However, the solution is as follows:
[tex]25 * 68[/tex]
Double 25 and half 68
[tex]25 * 68 = 50 * 34[/tex]
Double 50 and half 34
[tex]25 * 68 = 100 * 17[/tex]
The above is now easy to solve
[tex]25 * 68 = 1700[/tex]
Find the zeros of the function below, algebraically.
f(x)=(x-2)^2-64
Please show how you got answer and explain :D
Answer:
x=10 and x=-6
Step-by-step explanation:
f(x)=(x-2)²-64 (Given)
0=(x-2)²-64 (Set equation equal to 0)
64=(x-2)² (Add 64 to both sides)
±8=x-2 (Take the square root of both sides)
Because there are two possible roots, make 2 equations to find both:
8=x-2 and -8=x-2
10=x and -6=x
