SVEN [57.7K]3 years ago
3 0

Answer:

a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.

b) line 1 and 4 are parallel because they have the same slope: 2

c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.

d) line three crosses the y line at point 11

Step-by-step explanation:

Line 1. y = 2x - 3

Line 2: y = -2x + 3

Line 3: y = 5x + 11

Line 4: y = 2x - 10

Line 5: y = 1/2x - 5

2.4z+1.2z-6.5=0.7 I don't get it
almond37 [142]
Basically that answer is incorrect. If you'd learn about combining, multiplying, dividing or subtracting like terms, this will be a simple problem. To be specific, like term is a number with a letter with it.

For example, 2.4z is a like term.

so you can only add like term, not any other normal number. When two terms have the same "letter", you will have to do what the sign said so in the problem....

2.4z + 1.2z - 6.5 = 0.7
3.6z - 6.5 = 0.7 (Add but leave the z alone because you are not multiplying)

The final answer is 3.6z - 6.5 because you cannot do anything else to that problem.

3.6z-6.5=0.7 is not true.

Profit is always calculated as revenue minus expenses. If a company’s expenses were $10 million, write an equation that expresse
ivann1987 [24]

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

The profit is $15 million when revenue is $25 million

Step-by-step explanation:

The formula of the profit is P = R - E, where

  • R is the revenue
  • E is the expenses

If a company’s expenses were $10 million, wee need to write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) and then find the profit when revenue is $25 million

∵ P is the profit in millions of dollars

∵ R is the revenue in millions of dollars

∵ The expenses E were $10 million

∵ Profit = Revenue - Expenses

∴ P = R - 10

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

∵ The revenue R = $25 million

∵ P = R - 10

- Substitute the value of R in the equation

∴ P = 25 - 10

∴ P = 15

∴ The profit is $15 million

The profit is $15 million when revenue is $25 million

Please help when there are two x's i get confused. answer #3 with an answer!
igomit [66]

Answer:

x = 1

Step-by-step explanation:

We know that the two angles must be equal to each other. So:

65x - 12 = 43x + 10

First add 12 to both sides:

65x - 12 + 12 = 43x + 10 + 12

65x = 43x + 22

Then subtract 43x from both sides:

65x - 43x = 43x - 43x + 22

22x = 22

x = 1
