Since, A 3-mi cab ride costs $7.30 and a 8-mi cab ride costs $15.30.
In the information given above, we can consider these as the coordinate points on the axes.
Let (c, d) be the coordinates , where 'c' represents the total cost and 'd' represents the distance traveled.
Cost is on the 'y' axis and distance is on the 'x' axis.
Now, let the first point on the coordinate axes be (3, 7.30) and the other point is given by (8, 15.30).
For the given points say and , equation of line is given by:
where m(slope) is given by .
The equation of line for the given points is:
So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.
A = 2h(l + w)
A = 2hl + 2hw
A = h(2l + 2w)
÷ (2l + 2w)
A/(2l + 2w) = h

Answer:
<h2>
first piece: 5 in</h2><h2>
second piece: 10 in</h2><h2>
third piece: 32 in </h2>
Step-by-step explanation:
x - the length of the <u>first piec</u>e
2x - twice the length of the first piece (the length of the <u>second piece</u>)
6x - six times the length of the first piece
two inches more:
6x+2 - the length of the <u>third piec</u>e
first + second + third = 47 in {total length of the pieces of steel}
x + 2x + 6x + 2 = 47
9x + 2 = 47
9x = 45
x = 45:9
x = 5 in
first piece: 5 in
second piece: 2×5 = 10 in
third piece: 6×5 + 2 = 30 + 2 = 32 in
Its a because you have to do the change in y over the change in x which is
y2-y1
------
x2-x1
Answer: Program C allows students to earn a Mathematics degree (B.A. or B.S.) by combining courses in the Department of Mathematics with courses from one other department. In most areas of specializations, mathematical and/or quantitative courses in other departments are part of the math degree program. All Program C students take a minimum of five core math courses: Calculus I, Calculus II, Calculus III, Introduction to Linear Algebra, and a proofs course, usually either Introduction to Abstract Algebra or Fundamental Properties of Spaces and Functions I.
Step-by-step explanation: Hope this helps.
