1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t
Answer:
x = ¹/₂
y = 1
Step-by-step explanation:
Given system of equations:
<u>Multiply</u> the second equation by 3:
<u>Add</u> this to the first equation to <u>eliminate</u> the term in y:
<u>Solve for x</u>:
<u>Substitute</u> the found value of x into the first equation and <u>solve for y</u>:
Therefore, the <u>solution</u> to the given system of equations is:
x = ¹/₂ and y = 1

Answer:
17.99
Step-by-step explanation:
Trig Ratios:
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We can use trig ratio sine as we are given an angle ( 40° )and the hypotenuse (28) and we need to find its opposite side (w)
Recall that sin = opposite over hypotenuse
That being said we want to create an equation to solve for w
Now we solve for w
Step 1 multiply each side by 28
we're left with w = 17.99
