Answer:
Step-by-step explanation:
We are told that the average human heart beats 
times per day and there are 
days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.
Now we will solve this problem using exponent properties.
Our answer is in scientific notation we can represent it in standard form as 
times.
Therefore, average human heart beats in one year or 41975000 times.
Answer:
-1
Step-by-step explanation:
We can use the formula to find slope
(y2-y1) / (x2-x1)
y1 is the first Y coordinate in the first pair
y2 is the second one in the first pair
X1 is the first X coordinate in the frst pair
x2 is the second one In the second pair.
so if we put it together it’d look liek this
(5- (-) 2) / (-4 - 3)
5+2 / -4 + -3
7/-7
or -1
Given that the <span>consumption function is C = $200 billion + 0.9y,
The</span><span> marginal propensity to consume (MPC) is a
metric that quantifies induced consumption, the concept that the
increase in personal consumer spending (consumption) occurs with an
increase in disposable income (income after taxes and transfers).
</span><span>The marginal propensity to consume (MPC) is equal to ΔC / ΔY, where ΔC is change in consumption, and ΔY is change in income. It reprecents the slope of the consumption function.
Therefore, the MPC is 0.9.

7x-4y just combine all the x and all the y sice both the x here are positive you add them and there is only one y so just keep it as it is
