Answer:

  a) t(n) = 200n -238

  b) t(n) = 2.7n -4.3

Step-by-step explanation:

This is the same sort of problem as writing the equation of a line through two points. The slope (coefficient of n) is found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

And the constant term is found from one point and the slope:

  b = y1 -m·x1

As always, if you have a number of these to do, you can save some trouble by putting the formulas in a spreadsheet. It will guarantee the formula is executed without mistakes.

In the attached, we have labeled the points (n1, t1), (n2, t2) instead of (x1, y1) and (x2, y2).

__

a) t(n) = 200n -238

b) t(n) = 2.7n -4.3

Fill in the blank. In the triangle below, z=
My name is Ann [436]

Answer:

z = 38

Step-by-step explanation:

The sum of the angles of a triangle add to 180

z+ 90+52 = 180

Combine like terms

z +142 = 180

Subtract 142 from each side

z+142-142 = 180-142

z =38

Solve the literal equation a + 4b = 5b - 3a for a
frez [133]
Simplifying
a + 4b = 5b + -3a

Reorder the terms:
a + 4b = -3a + 5b

Solving
a + 4b = -3a + 5b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '3a' to each side of the equation.
a + 3a + 4b = -3a + 3a + 5b

Combine like terms: a + 3a = 4a
4a + 4b = -3a + 3a + 5b

Combine like terms: -3a + 3a = 0
4a + 4b = 0 + 5b
4a + 4b = 5b

Add '-4b' to each side of the equation.
4a + 4b + -4b = 5b + -4b

Combine like terms: 4b + -4b = 0
4a + 0 = 5b + -4b
4a = 5b + -4b

Combine like terms: 5b + -4b = 1b
4a = 1b

Divide each side by '4'.
a = 0.25b

Simplifying
a = 0.25b
