Y=30x+150 you put 3 in for x which is y=30(3)+150                                                       y=90+150                                                                                                               y=240

Answer:
$1230 

Explanation:
First of all, your initial equation is wrong. It should be:
cost = 30m + 150 

To find how much 3 years will cost you have to first find how many months are in 3 years:
12 • 3 = 36 
Then substitute 36 for m in the equation: 
cost = 30(36) + 150
Then solve: 
C = 30(36) + 150 
C = 1080 + 150 
C = 1230

1) You will begin by writing down the definition of "monetary policy."
stepan [7]

It should be noted that monetary policy simply means the policy that's adopted by the monetary authority in a country in order to control interest rates and the money supply.

<h3>Monetary policy.</h3>

Your information is unclear but the clear and complete ones will be answered appropriately. The main monetary policies include the reserve requirement, open market operations, discount rate, and the interest on reserves.

It should be noted that a larger money supply leads to the reduction of the market interest rates. This makes it less expensive for consumers to borrow.

Also, a smaller money supply raises the market interest rates. Expansionary monetary policy leads to an increase in the money supply. This will lead to an increase in expenditure and therefore, the aggregate demand will shift to the right.

Write the equation of a line that is perpendicular to y=7x−2 and passes through the point (14,8).(1 point) y=7x−90 y=10x−17 y=−1
True [87]

Answer:

\huge\boxed{y=-\frac{1}{7}x+ 10}

Step-by-step explanation:

In order to find the equation of this line, we need to note two things.

  • A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)
  • B) We can substitute a point inside an incomplete equation to try and find a missing value.

So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.

  • <u>Reciprocal of 7:</u>    \frac{1}{7}
  • <u>Opposite of </u>\frac{1}{7}:    -\frac{1}{7}

So the slope of this line will be -\frac{1}{7}. The y-intercept will change, and we can substitute what we know into the equation y=mx+b.

y = -\frac{1}{7}x+b

Now, we can substitute a point on the graph (14, 8) into this equation to find b.

  • 8 = -\frac{1}{7} \cdot 14 + b
  • 8 = -\frac{14}{7} + b
  • 8 = -2 + b
  • b = 10

Now that we know the y-intercept, we can finish off our equation by plugging that in.

y = -\frac{1}{7}x + 10

Hope this helped!
