The equation is y=1/2x+8 which has a slope of 1/2 and the y intercept is 8.
The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given slope is 1/2 and the line passing through point (-2, 7).
Now find the y intercept, b:
7=1/2(-2)+b
7=-1+b
b=8
Hence, the equation of line with slope 1/2 and point (-2, 7) is y=1/2x+8.

Robert purchased a 2010 model sedan for $16,000. The dealership offered
him a $99/month payment for 60 months, after which the unpaid balance is
due. If the interest rate is 6%, find the balloon payment due at the end of 60
months.
O
A. $17,513.12
O
B. $15,000
C. $18,153.21
O
D. $14,674.37
Answer:
The correct option is D. $14,674.37.
Step-by-step explanation:
This can be calculated using the ballon payment formula as follows:
P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)
Where:
P = Monthly payment = $99
PV = present value of the loan or the purchase price of the 2010 model sedan = $16,000
Ballon = Ballon payment due at the end of 60 months = ?
r = monthly interest rate = 6% / 12 = 0.06 / 12 = 0.005
n = number of periods or months = 60
Substituting the values into equation (1) and solve for Ballon, we have:
$99 = ($16,000 - (Ballon / (1 + 0.005)^60)) * (0.005 / (1 -(1 + 0.005)^-60))
$99 = ($16,000 - (Ballon / 1.3488501525493)) * 0.0193328015294284
$99 / 0.0193328015294284 = ($16,000 - (Ballon / 1.3488501525493))
$5,120.83051436193 = $16,000 - (Ballon / 1.3488501525493)
Ballon / 1.3488501525493 = $16,000 - $5,120.83051436193
Ballon / 1.3488501525493 = $10,879.1694856381
Ballon = $10,879.1694856381 * 1.3488501525493
Ballon = $14,674.3694203126
Rounding to 2 decimal places, we have:
Ballon = $14,674.37
Therefore, the correct option is D. $14,674.37.

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and Reno, Nevada, is 430 miles. Express the distance in kilometers.
A.
431.6 km
B.
268.8 km
C.
688 km
Answer:
B
Step-by-step explanation:
Answer:
The answer is C. 688 km
Step-by-step explanation:
you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k
and 665miles x 1.6 = 1064k
1 Mile is 1,6 Kilometers
430 Miles = 688 Kilometers (430 * 1,6)
665 Miles = 1064 Kilometers (665 * 1,6)
1. if you want your questions answered, don't whine -- just ask the question. for example, in this you haven't really asked anyone the question. They have to assume what you are trying to find out.
2. It is simple math if you understand the equation you gave:
You are solving for "k" which is kilometers;
You have been given the distance which is "d" in miles (430 miles and 665 miles)
The equation means: "k" equals 1.6 times the value of "d"
so the answers to your implied questions are:
k = 430 x 1.6 = 688 kilometers
k = 665 x 1.6 = 1064 kilometers
You might also asking your question in a more appropriate category. this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).
The number of kilometers is ALWAYS greater than the corresponding miles. For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.

Graph the relation. Is the relation a function? Why or why not?
{(-1, 1), (-2, 1), (-2, 2), (0, 2)}
Yes; there is only one range value for each domain value.
No; a range value has two domain values.
No; a domain value has two range values.
Yes; there is only one domain value for each range value.
Answer: The answer is letter B "No; a range value has two domain values".
For a relationship to be a function, there must be a one-to-one correspondence between the x and y values. For every value of x, there must be only one value for y. So the first set is a function and the second set is not.
Answer:
No; a range value has two domain values.
Step-by-step explanation:
Output has to be unique for all inputs.
Output for -2 is not unique
Step-by-step explanation: It is either B or C
Since
x = − 2
produces
y = 1
and
y = 2 , the relation
( − 1 , 1 ) , ( − 2 , 1 ) , ( − 2 , 2 ) , ( 0 , 2 )
is not a function.
The relation is not a function.

Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x)=2(3x+4)(x^2+2)
Answer:
Step-by-step explanation:
The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).
How was this obtained. notice that if x = 0 then
f(0) = 2(3*0+4)(0^2 + 2)
f(0) = 2(4)(2)
f(0) = 16 just as the graph tells us.

Brittany earned $835 babysitting this summer. She put her money into a savings account which earned 7.8% interest annually. If she leaves the money in the savings account for 3 months, how much interest will she earn?
Answer:
$16.28
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7.8%/100 = 0.078 per year,
putting time into years for simplicity,
3 months ÷ 12 months/year = 0.25 years,
then, solving our equation
I = 835 × 0.078 × 0.25 = 16.2825
I = $ 16.28
The simple interest accumulated
on a principal of $ 835.00
at a rate of 7.8% per year
for 0.25 years (3 months) is $ 16.28.
The population of a town is 15,000. It decreases at a rate of 8% per year. In about how many years
will the population be fewer than 10,000?
Answer:
5
Step-by-step explanation:
If a population is decreasing by 8% we can multiply the population by 92% (1-.08)
which means we have the following equation
population=15000(.92)ⁿ
where n is the number of years
we want to know when the population will be 10,000 so we write
10,000=15,000(.92)ⁿ
.66667=.92ⁿ
a rule we have is
[tex]n=y^x\\log_yn=x[/tex]
which means that
[tex].66667=.92^n\\=log_{.92}.66667[/tex]
compute this and get
4.867
round this up to 5

you would divide 200÷2 wich is 100
so then u add the other 200 with 100 to get 300
Answer: it is 200, not 300 unless you added 100 after.
