Please only answer if you actually know how to). Some methods for graphing equations work well with certain equations and some d

on't. Help Asap). Knowing which method to select based on the given equation is a valuable skill. You have learned three methods to graph equations. These methods are: • y = mx+ b, • find intercepts, • use a t-chart. A) Using the following 3 equations, answer the questions: 11x + y =4, x+y = -2, x - 2y = 18. 1) How can you determine which equations can be graphed more easily using x - and y -intercepts, rewriting in slope-intercept form, or using a table of values? 2) Which method works best for you personally? When does it not work as well?​

Answer:

please dont blame me if i get this wrong this is what i put.

Step-by-step explanation:

Using the following 3 equations, answer the questions:

11x + y =4, x+y = -2, x - 2y = 18

How can you determine which equations can be graphed more easily using x- and y-intercepts, rewriting in slope-intercept form, or using a table of values?

you can determin which is eiser to graph by wether or not they have numbers infront of the x and y intercepts.  i find it mutch eiser if they allready have the numbers there. its also eiser to graph 11x + y =4 and x - 2y =18 on a slope intercept rather than table of values because you allready can find the points for those two eiser than the last one which would be used on the table of values.  for the problem x+y=-2 you would use x and y intercepts. for 11x+y=4, rewriting in slope form is the corect method to use. and finaly use the table of values method for x-2y=18.

Which method works best for you personally? When does it not work as well?

the one that i find works best for me personally is probably gonna be the slope intercept method as apposed to many other methods. it doesnt work all the time because nothing can but normaly when i have a problem with this method i can just go to the table of values method and get the answer. (sorry if this is wrong this is what im putting for my answer. dont copy and paste this though if u do desiede to use it, read it and turn it into your own words so its not obvious you found the answer on the internet. and tbh i didnt read the lesson i just am ok at comming up with answers useing the question and getting away with it. )

1. Solve the system by substitution.
zubka84 [21]

Answer:

The required solution is (0.128,13.82)

Step-by-step explanation:

Consider the provided system of equation.

-2.5x+y=13.5......(1)

12.25x - y=-12.25......(2)

We need to solve the system of equation by substitution method.

Consider the equation 1.

-2.5x+y=13.5

y=13.5+2.5x ......(3)

Substitute the value of y in equation 2.

12.25x - (13.5+2.5x)=-12.25

12.25x-13.5-2.5x=-12.25

9.75x-13.5=-12.25

9.75x=-12.25+13.5

9.75x=1.25

x\approx 0.128

Now substitute the value of x in equation 3.

y=13.5+2.5(0.128)

y\approx 13.82

Hence, the required solution is (0.128, 13.82)

cain deposited $6033 into savings account 25 years ago the account has an interest rate of 4.2 and the balance is currently $720
Ksju [112]

Answer:

interest is compounded monthly

Step-by-step explanation:

there is a slight mistake in the question, the future value after 25 years is $17,208.63, not $7,208.63

the future value = present value x (1 + i/a)ⁿᵃ

future value = $17,208.63

present value = $6,033

i/a = 4.2%/a

n x a = 25a

(1 + 0.042/a)²⁵ᵃ = $17,208.63 / $6,033 = 2.852416708

²⁵√(1 + 0.042/a)²⁵ᵃ = ²⁵√2.852416708

(1 + 0.042/a)ᵃ = 1.042818

4.2818% would be the effective interest on the loan, so we can try different options for a. Since the effective interest is higher, I will try first with monthly compounding:

a = 12 (compounded monthly)

(1 + 0.042/12)¹² = (1 + 0.0035)¹² = 1.042818 ✓
