Answer:

(3, - 2 ) and (- 2, 2 )

Step-by-step explanation:

(8)

2x + y = 4 → (1)

x + 3y = - 3 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 2x - 6y = 6 → (3)

Add (1) and (3) term by term to eliminate x

0 - 5y = 10

- 5y = 10 ( divide both sides by - 5 )

y = - 2

Substitute y = - 2 into either of the 2 equations and solve for x

Substituting into (1)

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

solution is (3, - 2 )

---------------------------------------------

(9)

3x + 5y = 4 → (1)

x + 3y = 4 → (2)

Multiplying (2) by - 3 and adding to (1) will eliminate the x- term

- 3x - 9y = - 12 → (3)

Add (1) and (3) term by term to eliminate x

0 - 4y = - 8

- 4y = - 8 ( divide both sides by - 4 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

x + 3(2) = 4

x + 6 = 4 ( subtract 6 from both sides )

x = - 2

solution is (- 2, 2 )

Answer:

Option D

Step-by-step explanation:

By applying Pythagoras theorem in triangle ABC,

(Hypotenuse)²= (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

AC² = (40 - 15)² + (80 - 75)²

AC² = (25)² + 5²

AC² = 650

AC = √650

AC = 25.495 ft

Since, area of a rectangle = Length × Width

Therefore, area of the garden = 25.495 × 6

                                                  = 152.97

                                                  ≈ 153 ft²

Since, 150 is very close to 153, approximate area of the rectangular garden is 150 ft².

Option D is the answer.

Answer:

115.5 in²

Step-by-step explanation:

7 x 7 = 49

49/2 = 24.5

(20-7) x 7 = 13 x 7 = 91

24.5 + 91 = 115.5

Step-by-step explanation:

Answer:

No, it is not the same.

Step-by-step explanation:

1/4 * 8y = 2y

1/4 * -12 = -3

2y - 3 is not the same as 2y - 12

Answer:

No, because once you factor the 1/4 on the first equation you will get -3, not -12 making them not equalivent.

Step-by-step explanation:

Here is the complete question

Samantha invested $660 into an account that paid 3.5% interest compounded annually. Samantha did not make any additional deposits or withdrawals

What is the total amount of interest paid by this investment at the end of five years?

A- $115.50

B-$783.87

C-$123.87

$2,755.50

Interst = future value - amount invested

amount invested = $660

Future value = A( 1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years  

$660 x ( 1.035)^5 = $783.87

Interest = $783.87 - $660 = $123.87

Answer:

  B. 10

Step-by-step explanation:

If this is a list of statements in a programming language that is processed sequentially, y is assigned the value 9+1 = 10. There is no further assignment to y, even after the value of x is changed. So, the final value of y is 10.

__

Additional comment

Some programming languages do their processing in parallel, so that the definition of y would be updated when the value of x gets updated. In that case, the value of y would be changed to 5+1 = 6. Since this is not a choice, the problem is apparently supposed to be interpreted as above.

Answer:

Step-by-step explanation:

3n = 3² × 8                     3² = 3 × 3

n × 3 = 3 × 3 × 8            notice a times 3 on both sides of the equation

                                      divide both sides by 3

n =  3 × 8      

n = 24    <---------------- FINAL ANSWER

Given:

The expression is:

[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]

To find:

The value of the given expression when [tex]x=64[/tex] and [tex]y=27[/tex].

Solution:

We have,

[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]

Putting [tex]x=64[/tex] and [tex]y=27[/tex], we get

[tex]=((64)^2(27)-3)^0+(64)^{\frac{1}{3}}-(4(64))^{\frac{1}{2}}[/tex]

It can be written as

[tex]=((64)^2(27)-3)^0+(4^3)^{\frac{1}{3}}-(4)^{\frac{1}{2}}(64)^{\frac{1}{2}}[/tex]

[tex]=1+4-2(8)[/tex]           [tex][\because a^0=1,a\neq 0][/tex]

[tex]=5-16[/tex]

[tex]=-11[/tex]

Therefore, the value of the given expression [tex]-11[/tex] when [tex]x=64[/tex] and [tex]y=27[/tex].

x=2.5

Step-by-step explanation:

x+3.5/4=2(2x+2)/4

x+3.5=2x+2/2

x-2x+3.5=1

-x=(-3.5)+1

-x=(-2.5)

-x/(-1)=(-2.5)/(-1)

x=2.5

Answer:

17.2 cm

Step-by-step explanation: Each side would be 19 cm since a triangle has three sides. Next, we will use pythagorean theory. Since the equation would be a^2 + b^2 = c^2. Since 19^2 is 361 and is getting subtracted by 64 (we get it because at the bottom, we have to split it. also, 8 squared is 64). Then we get 297, which the base root with one number behind the decimal would be 17.2 cm.

Answer:

[tex]\Huge\boxed{C.68}[/tex]

Step-by-step explanation:

Hello There!

The exterior angle of a triangle rule is that the exterior angle  is equal to the sum of the interior opposite angles

So essentially what I'm saying is that

z = 29 + 39

29+39=68 therefore the measure of angle z is 68
