Answer:

Step-by-step explanation:

[tex]2 {x}^{2} - 4 {y}^{2} [/tex]

By putting the value of x = 2 and y = -3 then,

[tex] = ( 2 \times {2}^{2}) - (4 \times {( - 3)}^{2} )[/tex]

[tex] = (2 \times 4) - (4 \times 9)[/tex]

[tex] = 8 - 36[/tex]

= - 28 (Ans)

Answer:

√160

Step-by-step explanation:

For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12

y intercept = c = 12

Point is (0, 12)

For x intercept, we use y = m(x - d). We have

y = 3x + 12 → y = 3(x - (-4))

Compare both, x intercept = d = - 4

Point is (-4, 0)

Using distance formula,

Distance = √(0-12)² + (-4-0)² = √12²+4²

Distance = √144+16 = √160

.

Answer: y = 800

Step-by-step explanation:

3(y+200) = 3000

y+200 = 1000 (dividing 3 from both sides)

y = 800

Answer:

27

Step-by-step explanation:

The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.

Hope this helps!

Answer:

27

Step-by-step explanation:

LCM is the least common multiple of one or more numbers. we can find this by finding the factors of 9 and 27.

9, 18, 27, 36, 45, 54

27, 54, 81, 108

since 27 is the smallest factor of both 9 and 27, it is the least common multiple.

4+4=8

Answer:

ummm i dont think I can answer this question bc am a girl but if it was the other way around I say yes totally

and 4+4 is 8

Answer and Explanation

This is because they are both the same opposite number, and you are adding.

But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].

So, the answer is 0.

Hope this helps =)

Answer:

Step-by-step explanation:

Given the system of equations:

2x + 3y = 15

X + 3y = 0

What is x?

2x + 3y = 15

X + 3y = 0         subtract the bottom equation fron the top one

2x - x + 3y - 3y = 15 - 0        see how the 3y - 3y equates to zero

  2x - x  = 15

        x  =  15        Now for  extra credit what is y?  

                                  X + 3y = 0

                                 15 + 3y = 0

                                 15 - 15 + 3y = 0 - 15

                                          3y = -15

                                        3y/3 = -15/3

                                           y  =  -5

Answer:

[tex]\Huge\boxed{x=8}\\\\\Huge\boxed{y=138}[/tex]

Step-by-step explanation:

Hello There!

Knowing that the sum of the angles in a triangle is 180

we can use this equation to solve for x

180 = 90 + 5x + 2 + 6x

Step 1 combine like terms

90 + 2 = 92

5x  + 6x = 11x

now we have

180 = 11x + 92

step 2 subtract 92 from each side

180 - 92 = 88

92 - 92 cancels out

now we have

88 = 11x

step 3 divide each side by 11

11x/11 = x

88/11 = 8

we're left with x = 8

Now we plug in 8 into x for 5x + 2 so we can solve for y

5*8=40

40+2 = 42

Now we can solve for y

the angle measured 42 degrees and the angle labeled y are supplementary angles meaning that the sum of the two angles is 180

so to find y we subtract the given angle (42) from 180

180 - 42 =138 so we can conclude that y = 138

Notes: the little square represents a right angle which has a measure 90 degrees so thats where the 90 came from .

Answer:

18km

40.5km

Step-by-step explanation:

Let b = journey by bus

c = journey by bicycle

d = total journey

c = (2/3 x d) x 2/3

divide both sides by 2/s

c(3/2) = (2/3)d

c + 9km = 2/3d

c + 9km = 3/2 c

collect like terms and solve for c

3/2c - c = 9km

1/2c = 9km

c = 18km

2. IF cycling (18km) and walking (9km) make up 2/3 of the journey, 2/3 of the journey is 27km

2/3d = 27km

divide both sides by 3/2 to find d

d = 40.50 km

lol i cant explain

Answer:

the answer is A prime that is a set containing all the numbers in the universal set that can't be found in A

it is like removing A from the universal set

The resulting sets are not found in the set  {4, 5, 7, 8, 10, 13, 14, 16, 17, 19), therefore the choice that describes the set of numbers is (A U B)'

Sets is a collection of numbers of elements

Given the following sets

A = {1, 3, 6, 9, 12, 15, 18} and

B = {2, 9, 11, 20).

U = {integers from1 to20}

From the given sets:

A U B ={1,2,3, 6, 9, 11, 12,25, 18, 20}

The resulting sets are not found in the set  {4, 5, 7, 8, 10, 13, 14, 16, 17, 19), therefore the choice that describes the set of numbers is (A U B)'

Step-by-step explanation:

18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.

These two are not equivalent fractions

Answer:

No.

Step-by-step explanation:

Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:

18/14 > 1

10/15 < 1

18/14 > 10/15

Answer:

Area of the shaded region = 1.92 cm²

Step-by-step explanation:

From the picture attached,

Area of the shaded region = Area of the sector OMN - Area of the triangle OMN

Area of sector OMN = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]

Here, θ = Central angle of the sector

r = radius of the sector

Area of sector OMN = [tex]\frac{50}{360}(\pi )(6)^2[/tex]

                                  = 15.708 square cm

Area of ΔOMN = 2(ΔOPN)

Area of ΔOPN = [tex]\frac{1}{2}(OP)(PN)[/tex]

Area of ΔOMN = OP × PN

In ΔOPN,

sin(25°) = [tex]\frac{PN}{ON}[/tex]

PN = ONsin(25°)

     = 6sin(25°)

     = 2.536 cm²

cos(25°) = [tex]\frac{OP}{ON}[/tex]

OP = ONcos(25°)

OP = 6cos(25°)

OP = 5.438 cm

Area of ΔOMN = 2.536 × 5.438

                         = 13.791 cm²

Area of the shaded region = 15.708 - 13.791 = 1.917 cm²

                                             ≈ 1.92 cm²
