For each value of u, determine whether it is a solution to -15 = 1 - 4u

Mathematics
1 answer:
Alona [7]4 years ago
6 0

Answer:

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Plug each option into u then solve the equation and see if the answer matches -15.

Ex. -15 = 1 -4 (2)

     -15 = 1 -8

     -15 = -7

     -15 does not equal -7 therefore it is false. Use Pemdas to solve.

True or false: one factor that affects the slope of the aggregate demand curve is the multiplier effect.
Alenkasestr [34]

One factor that affects the slope of the aggregate demand curve is the multiplier effect is a "true" statement.

<h3>What is aggregate demand curve?</h3>

Aggregate demand would be a macroeconomic term which refers to the total consumption of goods and services in a given period at any price level.

Some key features regarding the aggregate demand curve?

  • Since the two metrics are estimated in the same way, aggregate demand over time corresponds gross domestic product (GDP).
  • GDP is the total quantity of products and services created by an economy, whereas aggregate demand is indeed the desire or demand for those goods.
  • The aggregate demand as well as GDP rise or fall together as a result of using the same calculation methods.
  • All consumer goods, capital equipment (factories & equipment), export markets, imports, & government spending programs are included in aggregate demand.
  • As long as the variables trade for the same market value, they are all considered equal.

Solve negative one fifth times the quantity 3 minus 12 times the quantity one third squared end quantity end quantity.
katrin [286]

The solution to the given equation is -87/45

<h3>Product of expressions</h3>

Given the following expression that represents the word problem as;

-1/5 * 3 - 12(1/3)^2

Using the PEMDAS rule, the parenthesis and exponent will come first to have;

-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)

Then multiplication

-1/5 * 3 - 12(1/9) =. -3/5 - 12/9

Find the difference

-1/5 * 3 - 12(1/9) = -27-60/45

-1/5 * 3 - 12(1/9) = -87/45

Hence the solution to the given equation is -87/45
