Answer:
y = -5x + 9.
Step-by-step explanation:
Lets look for the relation between x and y.
Try the first one:
When x = -2, y = -(-2) + 10 = 12
In the table y = 1 so its not this one.
Number 2:
x = -2, y = 10(-2) + 1 = -18 - Not thios one
Number 3:
When x = -2, y = -10(-2) - 9 = 11
Not this one
Number 4:
y = -5(-2) - 9 = 1
This is the one.
Check again with x = 0:
When x = 0, y = -5(0) - 9 = -9.

What is the graphical criterion to determine what second order polynomial has complex roots?
Second order polynomials are algebraic equations of the form:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
a, b, c - Coefficientsx - Independent variabley - Dependent variableA value of x is a root of the polynomial for y = 0, which can real or complex but not both according to the discriminant of the quadratic formula. If the polynomial has no real roots, then it does not pass through the x-axis in the real coordinate plane.

after 8 years?
After 8 years the worth would become $1,095.91
How to find the compound interest?If n is the number of times the interest is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
We are given that $550 invested at 9% interest compounded annually be worth after 8 years.
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
a = 550 (1 + 0.09)^8t
a = 550 (1.09)^8t
a =1,095.91
Hence, the worth would be; $1,095.91

please help find x and mDE
Answer:
x = 16
measure of Arc(DE) = 167°
Step-by-step explanation:
Since the arc EFG make a straight angle, we can infer;
180° = Arc(EF) + Arc(FG)
180° = (x-3)° + (12x - 25)°
180° = 13x - 28
208 = 13x
16 = x
Arc GF and DE are vertical angles so if you find the measure of Arc GF then it's the same as measure of Arc DE
mDE = mGF
mDE = 12x - 25
mDE = 12(16) - 25
mDE = 192 - 25
mDE = 167°

Answer: 7 hours.
Step-by-step explanation: Randall can assemble 5 race car tracks in an hour and Diggery can assemble 4 race car tracks in an hour. To see how many hours it takes to make 63 race car tracks, you need to add 5 and 4, since Randall and Diggery are working together. Both of them combined can make 9 race car tracks in total every hour. 63 can be divided by 9, which is 7. Therefore, it'll take 7 hours for both of them to make 63 race car tracks.

An account with a $250 balance accrues 2% annually. If no deposits or withdrawals are made, which graph can be used to determine approximately how many years will it take for the balance to be $282?
Answer:
D. Graph 4 In an account with 250$ balance that accrues 2% annually, with no deposits or withdrawals, it takes 6 years and 6 months for the balance to be 282$
Step-by-step explanation:
if the balance accrues 2% annually, then that means every year the amount increases by 100% + 2% = 102%
102%= 102/100 = 1.02
if we multiply the balance in the account with 102% or by 1.02 at the beginning of each year we will get the amount accrued at the end of the year
First year: $250 x 1.02 = $260.1
Second year: 260.1 x 1.02 = $265.302
Third year: 265.302 x 1.02 = $270.60802
we can use these points to create a graph that will help us estimate at what year the amount will be 282$

James and his family spend a morning picking peaches. They fill several bags. This line plot shows the weight of each bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?
The number of pounds that one of the heaviest bag weighs more than one of the lightest bag in the given line plot is: 1½
What is a Line Plot?In a line plot, frequency of a data point is either represented by a dot or a mark.
In the line plot given:
Heaviest bag weighs 5¾
Lightest bag weighs 4¼
The difference between the heaviest and lightest bag = 5¾ - 4¼
= 23/4 - 17/4
= (23 - 17)/4 = 6/4 = 3/2
= 1½
