Answer:
f(x) = -1/2x + 1
Step-by-step explanation:
Remember that f(x) = y
f(-2) = 2 tells you that when x = -2, y = 2 ; So you have point (-2, 2)
f(2) = 0 tells you that when x = 2, y = 0 ; So you have point (2, 0)
Now use the two points to find the slope: Slope = (change in y)/(change in x)
So slope = (0-2)/(2-(-2) = -2/4 = -1/2
Next find "b" using the slope and one point and solve for "b"
y = mx + b slope = -1/2 point (-2, 2)
2 = -1/2(-2) + b
2 = 1 + b
1 = b
Last thing to do: write the equation using slope = -1/2 and b = 1 into y = mx + b
y = -1/2x + 1
According to industry experts, the value of a new vehicle drops by about 20% in the first year of ownership. Over the next four years you can expect your cal to lose roughly 15% of its value each year. Meaning the average car will be worth just 40% of its purchase price after five years:)!
Answer:
A = 5*5=25
P = 5 + 5 + 5 + 5 = 20
Explanation:
If a square has an area of 25 ft then we need to look at the GCF
1,25 5,5 25,1
since it's a square its sides are equal so 5,5 are our length and width.
5 * 5 = 25
the perimeter is all sides added together, so if all sides are equal to 5 the perimiter is
5+5+5+5 = 20
Answer:
f(-2) = 3
Step-by-step explanation:
The graph goes through the point (-2, 3), indicating the value of f(x) is 3 when x=-2.
