Step-by-step explanation:
Rico owns a sporting goods store. He has agreed to donate $125 to the Centipede Valley High School baseball team for their equipment fund. In in addition, he will donate $18 for every home run the Centipedes hit during the season. The sequence shown represents the possible dollar amounts that Rico could donate for the season. 125, 143, 161, 179,
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete but it can still be solved.
To answer this question, I'll solve for the general formula which to determine Rico's donations
The given sequence shows an Arithmetic sequence; such that
[tex]First\ Term = T_1 = 125[/tex]
[tex]Common\ Difference = d = 143 - 125[/tex]
[tex]d = 18[/tex]
The general formula (Tn) is as follows:
[tex]T_n = T_1 +(n - 1)d[/tex]
Substitute values for T1 and d
[tex]T_n = 125 +(n - 1) * 18[/tex]
Open Bracket
[tex]T_n = 125 +18n - 18[/tex]
Collect Like Terms
[tex]T_n = 125 - 18+18n[/tex]
[tex]T_n = 107+18n[/tex]

solve the system of eqations
Answer:
(13/8, -5/4)
Step-by-step explanation:
substitute the value of y
{y=6x-11
2x-3y=7
solve the equation
2x-3(6x-11)=7
Substitute the value of x
x=13/8
Solve the equation
y=6x13/8-11
A possible solution is
y=-5/4
Check the solution
(x,y)=(13/8, -5/4)
Simplify
{-5/4=6x13/8-11
2x13/8-3x(-5/4)=7
The ordered pair is a solution
{-5/4=-5/4
7=7
Solution
(13/8, -5/4)
What is the y-coordinate of the vertex?
Y=2(x-3)( x-9)
Answer:
-18
Step-by-step explanation:
First, to find the y coordinate of the vertex, we need to find the x coordinate of the vertex.
The vertex will always be in the middle of the roots of the quadratic. The roots of the polynomial are 3 and 9, so the x coordinate of the vertex will be (3+9)/2 = 6.
Now that we know the x coordinate of the vertex, we can just plug in 6 for x to find the y coordinate:
2(6-3)(6-9)
=2(3)(-3)
=-18

The conjecture "for n > 3, all n-gons have an even number
of sides" is disproved by which statement?
A Hexagons have six sides.
B Pentagons have five sides.
1
Octagons have eight sides.
Quadrilaterals have four sides.
Answer:
pentagons have five sides
Step-by-step explanation:
We want to find out why the statement disprove the conjecture
What the conjecture assumes is that for all polygons with more than 3 sides, all polygons here having their names ending in ‘gons’ have an even number of sides
The term pentagon refers to a 5-sided polygon
This polygon thus have more than 3 sides. Since 5 is not an even number, then we can conclude that the conjecture has been disproven

x+25-25 = 33-25
x = 8
Hence the value of x is 8
Find the equation of the line that passes through the point (1,2) with a slope of 4. Plug in your values for a and b into the equation below.
y = ______x+_______
Answer:
y=4x-2
you can find the y intercept if you plot a confirmed point on a graph and follow the slope to the line.
Answer:
y = 4x - 2
Step-by-step explanation:
Since we are given the slope already, we can solve for the y-intercept using the slope, the given point, and the formula [ y = mx + b ]
y = 4x + b
2 = 4(1) + b
2 = 4 + b
-2 = b
Substitute with what we solved for into the formula.
y = 4x - 2

What is the value if the y-intercept of a line that passes through the points (3,-2) and has a slope of 4
Answer:
the y-intercept is -14
Step-by-step explanation:
To get the y intercept, you need to get the b from y = mx + b
y - y₁ = m (x - x₁)
m = 4
(x₁,y₁) = (3,-2)
y - (-2) = (4) (x - (3))
y + 2 = 4x - 12
y + 2 - 2 = 4x - 12 - 2
y = 4x - 14
y = mx + b
b = -14

1) Multiply the polynomials using the tabular method: (6x2 + 4x – 9)(5x + 1)
Answer:
its correct
Step-by-step explanation:
Each term of 6x^2+4x-9 is placed along the top of the table. Each term of 5x+1 is placed along the right side of the table.
We have 3 terms in 6x^2+4x-9 and 2 terms in 5x+1
So there are 3 columns and 2 rows leading to 3*2 = 6 cells total.
Each cell is filled in by multiplying the outer terms
For instance, row 1, column 1 has 6x^2*5x = (6*5)*(x^2*x) = 30x^3
The other cells are filled in the same way.
After the table is completed, you then combine like terms
20x^2 and 6x^2 is one pair which add to 26x^2
4x and -45x is another pair which add to -41x
The other terms are just added on, but not combined/simplified. This leads to the final answer shown on your paper.

The cost of a pack of pencils is $3 while the cost of a pack of pens is $5.
What will the cost be if you buy 4 packs of pencils and 4 packs of pen?
Answer:
The total cost would be $32
$12 for the pencils
$20 for the pens
The total cost if you buy 4 packs of pencils and 4 packs of pen at $3 and $5 respectively is $32.
Given the following data:
Cost of a pack of pencils = $3Cost of a pack of pen = $5Number of packs of pencils = 4 packsNumber of packs of pen = 4 packsTo determine the total cost if you buy 4 packs of pencils and 4 packs of pen:
First of all, we would determine the cost of 4 packs of pencils:
[tex]4 \;packs = 3 \times 4[/tex]
Four (4) packs of pencils = $12
For pen:
[tex]4 \;packs = 5 \times 4[/tex]
Four (4) packs of pen = $20
For total cost:
[tex]Total \;cost =12+ 20[/tex]
Total cost = $32

Rosalie and Emmet are having a disagreement. Rosalie thinks a line can have a line of symmetry, while Emmet
disagrees. What do you think: can a line have a line of symmetry? Why? Explain completely.
A line totally can have a line of symmetry. while it does not have width (therefore cannot put the line of symmetry through its "width"), it does have a length like any other shape. If we take a 4 unit line, we could put the line of symmetry at the 2 unit mark.
^sorry, im rushing a bit so you might have to paraphrase !
Answer:
Rosalie is correct, a line can have a line of symmetry.
Step-by-step explanation:
If you draw a line, a line of symmetry to that line would be perpendicular to the original line. Because lines are straight, they have an infinite number of lines of symmetry.
Jeremy drove from Portland to Miami. He determines that the expression 450x + 150 represents the distance in miles he traveled, where x is the number of days after the first day. Which statement describes correctly what the coefficient of x represents?
Answer:
The coefficient of x represents the number of miles driven each day.
Step-by-step explanation:
The coefficient of x is being multiplied by x, or the number of days. If the expression models the total distance travelled, then Jeremy drove 450 miles each day.

If Good C increases in price by 30 % a pound, and this causes the quantity demanded for Good D to increase by 40% , what is the cross-price elasticity of the two goods? Round your answer to one decimal place. What is the relationship between the two goods? Complements no relationship substitutes
Answer:
1.3
Substitutes
Step-by-step explanation:
Cross price elasticity,Edc = percentage change in Quantity demanded of D / percentage change in Price of C
Good C increases in price by 30 % a pound
Good D to increase by 40%
Cross price elasticity, Exy = percentage change in Quantity demanded of D / percentage change in Price of C
= 40% / 30%
= 1.333
To one decimal place = 1.3
When Edc > 0, Quanrity demand of good D and Price of good C
are directly related. D and C are substitutes
The goods are substitute
