Answer:
Given
f(x)=18,000(.88)^x
We need to find the value of x when f(x) <2000
2000 = 18000(0.88)^x
0.88^x 2000/18000
0.88^x 1/9
• x = log (1/9) / log (0.88)
• x= 17 (rounded down)
After 17 years or during year 18 the car value will drop below $2000
Step-by-step explanation:
what we trying to find the value of x and y
20x+6=y
x intercept,y=0
20x+6=0-6
20x/20=-6/20
×=-0.3
y intercept,x=0
20(0)+6=y
0+6=y
6=y
(-0.3,0)
19x+7=y
y intercept,x =0
19(0)+7=y
0+7=y
7=y
x intercept,y=0
19x+7=0-7
19x=-7
19x/19=-7/19
x=-0.37
Answer:20 girls
Step-by-step explanation:the difference between 3 and 4 is one so there will be a difference of one between the 2 questions.
Since 19 is a prime number (a number that only has 2 factors: one and itself), 19/36 is the simplest form.
Answer:
12
Step-by-step explanation:
This value would be 2(-1)^2*2(3). I have enclosed the given values of x and y for clarity.
This works out to 2(1)*2(3) = 12.
