Kelly bought a soda for three dollars and 7 candy bars when she went to the movies. She spent a total of $21. How much did each candy bar cost? Write out and solve. Show work
Answer:
$2.57
Step-by-step explanation:
Create an equation.
7x + 3 = 21
Subtract 3 from both sides of the equation.
7x = 18
Divide 7 from both sides to find x.
18/7 = x,
x = 2.57
Each candy bar costs 2.57 dollars,

A company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50
Based on this information, which graph best shows this relationship between the cost y, and the number of cubic yards, X?
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.
Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.
What is graph?In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Let the total cost be y and the number of cubic yards be x.
Now, the equation to represent the given situation is y = 50+50x
By substituting x = 0, 1, 2, 3, 4, 5,....we get
y = 50+50(0) = 50
y = 50+50(1) = 100
y = 50+50(2) = 150
y = 50+50(3) = 200
y = 50+50(4) = 250
So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Find the third degree polynomial function that has an output of 40 when x = 1, and has zeros - 19 and -i?
Answer:
f(x) = x³ + 19x² + x + 19
Step-by-step explanation:
Zeros: -19 , -i, complex conjugate root: +i
Function: (x+19)(x+i)(x-i) = 0
(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19
check: when x = 1
f(1) = 1 + 19 + 1 +19 = 40
If I worked all these hours, how much should I be paid. It's 13.69 per hour btw each. Schedule:
9/13 Monday 10am-2:00pm
9/14 Tuesday 10am-2:00pm
9/15 Wednesday 10am-2pm ( Campus or Zoom)
8/16 Thursday 10am-2pm. Two weeks later I work two hours which is 27.38. How much money should I get with all of this in total.
Answer:
$246.42
Step-by-step explanation:
13.69(4+4+4+4) + 27.38
13.69(16) + 27.38
219.04 + 27.38
246.42
You should make $246.42.

1. What is the structure of a proof in geometry?
2. Is ray AB the same as ray BA?
3. What is the difference between the m<A(measure of angle A) and <A (angle A)?
Answer:
1.Geometric proofs can be written in one of two ways: two columns, or a paragraph. A paragraph proof is only a two-column proof written in sentences. ... A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true.
2.ray AB is not same as ray BA as ray AB has the starting point A and ray BA has B as the starting point.
3.∠ABC refers to an angle, a geometric object.
m∠ABC refers to the measure of ∠ABC which is a real number describing how “open” the angle is.

Answer: 6003.2
Step-by-step explanation:
Given the sequence 1/2 ; 4 ; 1/4 ; 7 ; 1/8 ; 10;.. calculate the sum of 50 terms
Hint :-
Break the given sequence into two parts .Notice the terms at gap of one term beginning from the first term .They are like [tex]\dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] . Next term is obtained by multiplying half to the previous term . Notice the terms beginning from 2nd term , [tex]4,7,10,13[/tex] . Next term is obtained by adding 3 to the previous term .Solution :-
We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,
[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .
We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,
[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]
Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .
[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]
[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]
[tex]\rule{200}2[/tex]
Now the second sequence is in Arithmetic Progression , with common difference = 3 .
[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]
Substitute ,
[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]
Hence sum = 908 + 1 = 909

2x+3y=24 in slope intercept form
Answer:
3y = -2x + 24
y = -2/3x + 8
Step-by-step explanation:
Answer:
The slope-intercept form is y=mx+b y = m x + b
Step-by-step explanation:
where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .
f(x)=2+|x-3| for all x than the value of the derivative of x=3 is
The derivative at x = 3 does not exist.
To see why, recall the definition of absolute value:
[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]
If x - 3 ≥ 0, then
2 + |x - 3| = 2 + (x - 3) = x - 1
and the derivative of this piece is 1 for all x > 3.
If x - 3 < 0, then
2 + |x - 3| = 2 - (x - 3) = 5 - x
and its derivative is -1 for all x < 3.
The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Susan is choosing tween two cell phone plans that offer the same amount of free minutes.
Plan A charges $29.99 per month with additional minutes costing $0.45
per minute.
Plan B charghes $39.99 a month with addtional minutes costing $0.40 per minute. If the equation for Plan A is
0.45x + 29.99 and the equation for plan E
is 0.40x+ 39.99, then how many addtional minutes, x, will it take for the two plans to cost the same?
Answer:
200
Step-by-step explanation:
You can simply just graph it and see where the points intersect, or you can do it algebraically.
0.45x+29.99=0.40x+39.99 subtract 29.99 both sides
0.45x=0.40x+10.00 subtract .40x both sides
0.05x=10.00 divide both sides by 0.05
x=200
