Answer:
after 10 years there will be $600000 in my account
Answer:
(b) 
Step-by-step explanation:
Given: Cost of car is 
Sales tax is 
The license and title charges are 
To find: The amount that the credit union will finance.
Solution:
We have,
Cost of car
Sales tax is of
Therefore,
sales tax 
The license and title charges 
Now, the amount that the credit union will finance is
cost of car
sales taxthe license and title charges
Hence, the amount that the credit union will finance is .
So, (b) is correct.
Answer:
-x<-16
Step-by-step explanation:
4-3(1-x)
x=-1
7-2(x+2)
x=2
Answer:600
Step-by-step explanation:
300,000/ 500 =600
ASSUMING This is a straight line so we gotta the formula for a straight line which is y=mx+b, where m represents the slope and b represents the y intercept.
First, we know this line passes through (5,8) and (9,2) we can use these for finding the equations. When we know two points, we use this formula:
y-y=m(x-x)
The first y is 8 and the second one is 2
The first x is 5 and the second one is 9
Plug it in:
8-2=m(5-9)
6=m(-4)
6/-4=m <— simplify this
m= -3/2
*NOTE: another way to find m is by calculating it (y-y)/(x-x)
Now we know m, we have to find b.
All you gotta do is plug everything you know back into the equation y=mx+b
y=mx+b
y=-3/2x+b <— now plug in a point we know(x,y)
8=-3/2(5)+b
8=-15/2+b
8-(-15/2)=b
b=8+15/2
b=16/2+15/2
b=31/2 (now you can write be as a fraction or a decimal in your equation, depending on what your teacher told you to use)
*NOTE: it is best to use fractions instead of decimals as it is more accurate sometimes.
Now we know all the variables that need to be known, we just need to rewrite the formula of the equation so the teacher can see.
m=-3/2
b=31/2
We don’t need to plug in x or y since it could have different values (since a straight line has MANY co-ordinates)
SO OUR EQUATION IS=
y=(-3/2)x+31/2
Hope you understand this, feel free to ask me anything!
