Answer:
A. 1.4*20 quarters
B.14
Step-by-step explanation:
A: 1.you start with 20 quarters= 20*1
2.you find 40% of twenty quarters in your room= 4/100*20=0.4*20
3.20*1+20*0.4= 20*1.4
B:20*1.4=28
28*50/100=14

Jeremy is solving this system of equations algebraically. Which equation could be a step in his work? y=3x+1 4x-3y=-13
Answer: c
Step-by-step explanation:
I did it
The solution for the system of equations → y = 3x + 1 and
4x - 3y = -13 is (2, 7)
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the system of equations as -
y = 3x + 1
AND
4x - 3y = -13
Plot the graph of both of these equations. The point of intersection, would be the solution of this system of equations. Refer to the graph attached. These lines intersect at (2, 7)
Therefore, the solution for the system of equations → y = 3x + 1 and
4x - 3y = -13 is (2, 7)

In order to lure new customers to a credit card, a bank is offering an initial cash back award, plus cash back amounting to a percentage of the value of all purchases made with the card the value of all purchases made with the card and the amount of cash back which of these equations does the graph represent ?
Answer:
A. [tex] c = 0.03p + 150 [/tex].
Step-by-step explanation:
The equation can be written in slope-intercept form as [tex] c = mp + b [/tex], where:
c = cash back (dollars)
p = value of purchases (dollars)
m = slope of the graph
b = y-intercept, which is the initial cash back award.
All we need to generate an equation that represents the graph, we need to find out the value of m and b.
b = until cash back award = 150
The slope, m, can be calculated using two points in the line, (1000, 180) and (2000, 210):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{210 - 180}{2000 - 1000} = \frac{30}{1000} = 0.03 [/tex]
Substitute m = 0.03, and b = 150, in [tex] c = mp + b [/tex].
The equation would be:
✅ [tex] c = 0.03p + 150 [/tex].
Expand.
Your answer should be a polynomial in standard form.
(3c + 2)(c^2-6c-4)
Answer:
After expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]
Step-by-step explanation:
We need to expand the polynomial [tex](3c + 2)(c^2-6c-4)[/tex]
Multiply the terms:
[tex](3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8[/tex]
So, after expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]

The table shows your scores in a skateboarding competition. The leader has 311.62 points. Select the equation that you can use to find how many points p you need in the fourth round to tie the leader. Then solve the equation to determine how many points you need in the fourth round to take the lead in the competition.
Find the second part please.
Answer:
✅[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
✅To take the lead, your score in the fourth round must be greater than 79.08.
Step-by-step explanation:
If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:
[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
Solve for the value of p
[tex] p + 232.54 = 311.62 [/tex]
Subtract 232.54 from each side
[tex] p = 311.62 - 232.54 [/tex]
[tex] p = 79.08 [/tex]

Mathematicians seek and use patterns[8][9] to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof. When mathematical structures are good models of real phenomena, mathematical reasoning can be used to provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.
Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements.[10] Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.[11]
Mathematics is essential in many fields, including natural science, engineering, medicine, finance, and the social sciences.

find 2u if vector u has initial point of (2,-1) and terminal point (3,1)
Answer:
2u = (2,4)
Step-by-step explanation:
Given that
Initial Point of vector = P1 = (2,-1)
Terminal point of vector = P2 = (3,1)
When the initial and terminal points of vector are given. The vector can either be directly found by using P2-P1 or the unit vectors i and j can be used.
So,
[tex]u =P_2-P_1 = (3-2 , 1-(-1))\\= (1, 1+1)\\=(1,2)[/tex]
Now we have to find 2u
So,
[tex]2u = 2(1,2) = (2,4)[/tex]
Hence,
2u = (2,4)
