Jason wants to solve the following system using the elimination method:

x + 3y = 10
2x + y = 5

What number should the equation 2x + y = 5 be multiplied by to eliminate y?

a. 2
b. -3
c. -2
d. 3

Answers

Answer:

No single Correct answer. Both b and d will work

Step-by-step explanation:

You want to get rid of y.

The first equation has a 3 in front of the y

Therefore you would have to multiply the second equation by 3 or - 3

If you use -3 you would add the two equations

If you use 3 you would subtract the two equations.

It is either b or d. Both will give you the same answer.

- Three

  x + 3y =   10

-6x - 3y = - 15               Add

-5x = - 5                       Divide by - 5

x = -5/-5

x = 1

+ Three

x   + 3y =  10

6x + 3y = 15                   Subtract

-5x = - 5

x = -5/-5

x = 1                                Same thing.

You have $350,000 to invest. Which investment would yield the greater return in three years; an investment that pays 2.5% compounded monthly or an investment that pays 2.45% compounded daily?

Answers

Answer:

Its better to invest at 2.45% interest rate compounded daily.Step-by-step explanation:

We are given

Principal Amount = $350,000

Time t = 3 years

We need to determine which investment will yield greater return

a) 2.5% compounded monthly

b) 2.45% compounded daily

The formula used will be: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

a) 2.5% compounded monthly

We have P=$350,000 t= 3 years,  r = 2.5 or 0.025 and n= 12

Putting values and finding A

[tex]A=P(1+\frac{r}{n})^{nt}\\A=350000(1+\frac{0.025}{12})^{12*3}\\A=350000(1.0021)^{36}\\A=350000(1.079)\\A=377650[/tex]

So, the return of investment in 3 years would be $377650 if interest rate is 2.5% compounded monthly.

a) 2.45% compounded daily

We have P=$350,000 t= 3 years,  r = 2.5 or 0.025 and n= 365

Putting values and finding A

[tex]A=P(1+\frac{r}{n})^{nt}\\A=350000(1+\frac{0.0245}{365})^{365*3}\\A=350000(1.000067)^{1095}\\A=350000(2.0821)\\A=728735[/tex]

So, the return of investment in 3 years would be $728735 if interest rate is 2.45% compounded daily.

So, if we invest 2.45% interest rate that is compounded daily we will make $728735 while if we invest 2.5% interest rate that is compounded monthly we will make $377650

So, its better to invest at 2.45% interest rate compounded daily.

Answer:

  20, 31, 42, 53, 64, 75, 86, 97

Step-by-step explanation:

The difference of 18 means the difference of digits is 18/9 = 2. Since the number you seek is the larger number, the 10s digit will be 2 more than the 1s digit. Possible numbers are ...

  20, 31, 42, 53, 64, 75, 86, 97

_____

If t and o are the tens and ones digits respectively, the relation you seek is ...

  (10t +o) -(10o +t) = 18

  9(t -o) = 18

  t - o = 2 . . . . as above

Since both t and o must be single digits, the minimum will be t=2, o=0, and the maximum will be t=9, o=7.

Answer:

10a+b=10b+a-18

9a+9b = -18

9(a+b) = -18

a+b = 18/9

a + b =2

a) The sixth term of an AP is twice the 3rd term and the first term is 3. Find the common
difference and the 10th term​

Answers

Answer:

Step-by-step explanation:

The nth term of an AP is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

Sixth term

T6 = a+(6-1)d

T6 = a+5d

Third term;

T3 = a+(3-1)d

T3 = a+2d

If the sixth term of an AP is twice the 3rd term, then

a+5d = 2(a+2d)

a+5d = 2a+4d

Given a = 3

3+5d = 2(3)+4d

5d-4d = 6-3

d = 3

Common difference is 3

For the 10th term

T10 = a+9d

T10 = 3+9(3)

T10 = 3+27

T10 = 30

Hence the tenth term is 30

Solve for A please :)

Answer:

a = 54 deg

Step-by-step explanation:

Recall that for a triangle, any exterior angle equals the sum of its two remote interior angles (see attached for reference).

In our case the exterior angle is 2a and the remote interior angles are (a+10) and 44

hence,

2a = (a+10) + 44

2a = a + 10 + 44

2a = a + 54   (subtract a from both sides)

2a - a = 54

a = 54 deg
