The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.
Which function represents the value of the car after t years?
O f(t) = 1.15(21,000)
O f(t) = 21,000(1.15)
O f(t)21,000(0.85)
O f(t) = 0.85(21,000)
Answer:
f(t) = 0.85(21,000)
Step-by-step explanation:
100% - 15% = 85% 0r in decimal form 0.85
0.85 x the original pricen 21,000
Answer:
the answer for this question is: f(t)=21,000(0.85)^t
Step-by-step explanation:
well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.

Answer:
7a + b - 16c
Step-by-step explanation:
So we have
7a-3b+c-8c+4b-9c
When it comes to problem like these, you need to combine like terms.
There's only one 'a' number, so that one remains the same.
Next, we have -3b and 4b. (-3b+4b)= b
Finally, there's (c-8c-9c).
(-8c-9c)= -17c
Take that and add the positive 'c' to it.
(-17c+c)= -16c
Put it all together now to get:
7a + b - 16c
I hope that helped and helped you understand at least a little

Please help me find the answer for ABE ASAP plss!!
(Do not put links!!!)
Answer:
122
Step-by-step explanation:
The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.

Step-by-step explanation:
F(x)=400-4/5x find the function and intercepts
Answer:
The x-intercept is (500, 0); the y-intercept is (0, 400).
Step-by-step explanation:
F(x)=400-4/5x is already a function: a function of x.
To find the y-intercept, set x = 0 and calculate F(0):
F(0) = 400 - 0 = 400; the y-intercept is (0, 400).
To find the x-intercept, set F(x) = y = 0 and solve for x:
0 = F(x) = 400 - (4/5)x, or (4/5)x = 400. To isolate x, multiply both
sides by (5/4): x = (5/4)(400) = 500. The x-intercept is (500, 0).
ABC is isosceles.
m < a = 3x + 40 and m < c = x + 50
what is m < a ??
Answer:
55°Step-by-step explanation:
It is assumed the angles A and C are congruent:
3x + 40 = x + 503x - x = 50 - 402x = 10x = 5m∠A = 3*5 + 40 = 55°
Answer:
solution given:
m<a=m<c
3x+40=x+50
3x-x=50-40
x=10/2=5
now
<a=3×5+40=55°

Brianne's town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm:250 cm. What is the area of the pool in square meters? Enter the area of the pool in the box.
Answer:
[tex]A=1250m^2[/tex]
Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as
[tex]L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m[/tex]
Therefore Area Aof main pool is mathematically given as
[tex]A=50m*25m=1250 m^2[/tex]
[tex]A=1250m^2[/tex]

You are the owner of the biggest and newest roller coaster called the Gentle Giant. The roller coaster costs $6 to ride. The operator of the ride must pay $200 per day for the ride rental and $65 per day for a safety inspection. If you want to make a profit of at least $1,000 each day, what is the minimum number of people that must ride the roller coaster? Write an inequality that can be used to find the minimum number of people, , which must ride the roller coaster each day to make the daily profit.
Answer:
Inequality: 6r - 200 - 65 [tex]\geq[/tex] 1000 and minimum of 211 people
Step-by-step explanation:
Let r = rides
6r - 200 - 65 [tex]\geq[/tex] 1000
6r - 265 [tex]\geq[/tex] 1000
6r [tex]\geq[/tex] 1265
r [tex]\geq[/tex] 210 [tex]\frac{5}{6}[/tex]
Needs 211 people to make a profit of at least $1000

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)
then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)
Now plot these two points (3,0) and (6,-1) on graph..
Hope it helps u..!!

The value of -4 5/8 - x is positive. What are two possible values of x?
Answer:
-6, -7
Step-by-step explanation:
basically
-4 5/8 - x >0
so
x< -4 5/8
you just need 2 values less than -4 5/8
like -6 and -7
The possible values of x could be x = -20 or x = -10 that satisfy the inequality.
Given: -4 5/8 - x > 0
To find two possible values of x that make the expression -4 5/8 - x positive, set up an equation and solve for x.
First, let's convert -4 5/8 to an improper fraction.
The improper fraction equivalent of -4 5/8 is -37/8.
So, -37/8 - x > 0
To isolate x, move -37/8 to the other side of the inequality by adding it to both sides:
x < -37/8
Now, Two possible values of x could be:
x = -20 or x = -10
Both of these values are less than -37/8, so they satisfy the inequality and make the expression -4 5/8 - x positive.

Can someone please help me with this question
Please check this answer
Please tell me if it’s correct if it’s not please answer it correctly please
Step-by-step explanation:
Hey,
I'm sorry, this is not correct. For a reflection, all you have to do is count the number of points from that specific point to the line. So, for example, w is 6 units away from the line, in order to draw that, count 6 units and graph. It's pretty hard to explain, but remember the shape is being reflected, so the orientation must change. I suggest searching this up.
Let me know if you have any more questions and I'll be more than glad to help.
