Answer:
b = 5
Explanation:
add both of the equations together
3a - c = 5b
3a + 3b - c = 40
= 3b = 40 - 5b
then make it equal to 40 meaning
8b = 40
b = 5
Complete question:
<em>What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di)
</em>
<em>choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2</em>
<em />
<em>Option D</em><em> is correct. </em> The value of c and d for the expression to be real are -3 and -2 respectively
Given the expression
Expand the expression
Collect the like terms
For the resulting function to be real, then the imaginary part must be zero i.e.
If d = -2, then;
Hence the value of c and d for the expression to be real are -3 and -2 respectively.

Explanation:
That's very guilty action.
MPC stands for "marginal propensity to consume," which refers to a rise in consumer spending for every unit of income level achieved.
Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.
Spending multiplier = Increase in income level for each unit increase in autonomous spending = 1/(1-MPC) = 1/MPS Spending multiplier = Increase in income level for each unit increase in autonomous expenditure. This is further explained below.
<h3>What is a multiplier?</h3>
Generally, the amount by which the return on investment is greater than the investment itself is referred to as the investment's return on investment (ROI).
In conclusion, Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.
