The x is a placeholder for a number. Think of x like a box and inside the box will go a number. In this case, -4 will replace x
7 - 2x = 7 - 2(-4) = 7 + 8 = 15
<h3>Answer: 15</h3>
Answer:
Step-by-step explanation:
Distance formula: ![\sqrt{(x2 - x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2%20-%20x1%29%5E2%2B%28y2-y1%29%5E2%7D)
(1-(-3))^2 - (-2-4)^2 = 16 + 36 = 20
![\sqrt{52}](https://tex.z-dn.net/?f=%5Csqrt%7B52%7D)
To get the effective interest rate (EIR) of the loan, determine first whether we will use a simple interest method or a discounted method. In this case, we will use a discounted method because the loan is a discounted one. In a discounted method, interest is deducted from the loan principal. So the formula will look like this:
EIR = Interest ÷ (Principal - Interest)
Before proceeding any further, solve first for interest. (assuming a 360-day year)
Interest = Principal × rate × interest
= $2950 × (100/360) × (0.085)
= $69.65
Thus, EIR can be computed as follows:
EIR = ($69.65 ÷ ($2950 - $69.65)) × 360
≈ 8.7%
Notice that the EIR was multiplied by 360 to return it to an annual rate.
the answer is 5.411.
