First you wanna calculate the sum

(1/3+1/9)×4²+5/18=

-2/9×4²+5/18

Then you wanna evaluate the power

(1/3+1/9)×4²+5/18=

-2/9×16+5/18

Now you are gonna calculate the product

-2/9×16+5/18=

Answers

Answer:

Y=15x

Step-by-step explanation:

So easiest way to do slope is to count rise over run. But this question is tricky because it’s not the same spaces in each increment.
Like the x is 1,2,3,4 and the y is 15,30,45,60 etc.

So the formula is y=mx+b
m stands for slope
b is for y intercept. That means what is the y when x is 0.

So first slope. m=y2-y1/x2-x1 or rise/run. Rise as in the y axis and run as in the x axis.

So let’s use the first 2 points. (0,0) (1,15)
15-0/1-0= 15/1= 15
So m=15

For b, when x is zero, y is also zero. So you would just leave that part out. I mean I guess you can put a +0 but it’s unnecessary.

So y=15x

Ps. You can also try diff points for m. 30-15/2-1 = 15/1=1 ect. Even like 60-15/4-1= 45/3 = 15

Answers

Answer:

Let us mark the points R and S on line p, T and U on line q, A and B on line l and C and D on line m.

Suppose the lines p and q intersect the line l at K and L respectively and line m at N and M respectively.

Since, AB is a straight line and ray KN stands on it, then

∠NKL + ∠NKA = 180∘ (Angles in a linear pair)

⇒110∘ + a = 180∘

⇒a = 180∘ − 110∘ = 70∘

Since, line p || line q and line l is a transversal intersecting them at K and L, then

∠TLB = ∠NKA (Alternate exterior angles)

⇒b = a

⇒b = 70∘

Since, line p || line q and line m is a transversal intersecting them at N and M, then

∠CNK = ∠NML (Corresponding angles)

⇒c = 115∘

Since, CD is a straight line and ray ML stands on it, then

∠NML + ∠LMD = 180∘ (Angles in a linear pair)

⇒115∘ + d = 180∘

⇒d = 180∘ − 115∘ = 65∘

What is a set theory?

The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.

Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,

U = {1, 2, 3, 4, 5

A =  {1,5}

A' = {2,3,4}

Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Callie was billed $416.48 for car repairs. She will pay the service center in 4 equal monthly installments from her bank account. What is the net change in her bank account balance after each monthly payment? Complete the steps below to solve this problem and others like it.
Part B
Which rational number represents the number of months that Callie has to pay off the bill? What does the sign on the number mean?

Part C
Write an expression to represent the net change to Callie’s account balance each month.


Part D
Simplify the expression in part C to find the net change to Callie’s account balance each month.
Part E
After paying the car service center in full, Callie realizes that she should start saving money each month for her future. She decides to invest the same monthly amount that she was paying the service center in a retirement fund. If she invests in the retirement fund for one year, what will the net change in her account balance be during that time

Part F
What is the sign of the net change in part E? Why does the sign make sense in this situation?

Answers

Part A The net change to Callie’s bank account is -$416.48. The negative sign indicates money leaving Callie’s account.

Part B Callie has 4 months to pay off the bill. The rational number is +4. The sign is positive because it represents a quantity of something, in this case, months.

Part C The amount of the bill, -$416.48, will be deducted from Callie’s account in equal amounts over 4 months. So, the expression representing the net change in her account balance each month is -416.48/4 .

Part D -416.48/4=104.12

Part E The monthly withdrawal from Callie’s account continues to be -$104.12. After 1 year (12 months), the net change to her account balance will be -$104.12 × 12 = -$1,249.44.

Answer:

part a)

ANSWER: The net change to Callie’s bank account is -$416.48. The negative sign indicates money leaving Callie’s account.

part b)

ANSWER: Callie has 4 months to pay off the bill. The rational number is +4. The sign is positive because it represents a quantity of something, in this case, months.

part c)


ANSWER: The amount of the bill, -$416.48, will be deducted from Callie’s account in equal amounts over 4 months. So, the expression representing the net change in her account balance each month is -416.48/4 .

part d)

ANSWER: -416.48 / 4= -$104.12

part e)

ANSWER: The monthly withdrawal from Callie’s account continues to be -$104.12. After 1 year (12 months), the net change to her account balance will be -$104.12 × 12 = -$1,249.44.

part f)

ANSWER: The net change is -$1,249.44. The sign is negative because it represents money leaving, or being deducted from, Callie’s bank account.

What is the equation of this line? Please help I will give extra points and the brain thing.

y=−3x−4/3

y=4/3x−3

y=3/4x−3

y=−3x−3/4

Answers

The equation of this line is y= 3/4x - 3
Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope
y=3/4x -3. You find the slope which is rise 3 and run 4 so it’s 3/4. Then the y intercept is already given to you since it’s just where the slope crosses the y axis. Y intercept is -3.
