Answer:

All of them are true.

Step-by-step explanation:

x^2 y - z / x^2 is true. x^2, when divided by itself, cancels itself out, so the equation that is left is y - z.

For the second one, a/c + b/c is true because when you add a + b = it will change; it will be added together. the remaining c will stay the same, as it is the denominator/the same, so you keep it as it is.

For the final one, you distribute ^2 to (a+b), so they become a^2 + b^2.

This means that all of the statements are true.

Step-by-step explanation:

Answer:

X-3Y=12 and 6Y-2X=7

Step-by-step explanation:

Step 1: Write all the equations in the form y=mx+c, where m represents the gradient.

Step 2: Find the equations with same value of m, ie., same gradient.

NB: Same gradient means that the lines are parallel.

Answer:

if you want to find which lines are parallel you must look at the slopes

Step-by-step explanation:

and you for this you must alone x

1) 3y=-x+5 slope is -⅓

2)3y=x-12 slope is ⅓

3)y=3x-2. slope is 3

4)6y=2x-7 slope is 2/6=⅓.

Finally the answer is 2 and 4 is parallel

Answer:

Step-by-step explanation:

4x + 2y = −2

Divide by two on both sides

2x+y = -1

subtract 2x from both sides

y = -1 -2x = -2x -1

Answer:

y = -2x - 1

Step-by-step explanation:

4x + 2y = -2

→ Minus 4x from both sides

2y = -4x - 2

→ Divide both sides by 2

y = -2x - 1

Answer:

x = 45 °

Step-by-step explanation:

We know that the sum of all angles if right angle triangle is 180 °.

90 ° + x + x = 180°

90 ° + 2 x = 180 ° ...( combine like terms)

2 x = 180 ° - 90 °.. ( subtract 90° from 180° )

2 x = 90°

x = 90° /2 ....( divide by 2 )

x = 45 °

Answer:

Shoe rent is $4.5

Step-by-step explanation:

Let the shoe rent is "x" which will remain the same irrespective of the number of bowling and "y" is bowling.

thus, x + 2y = 16.50

Rewrite, x = 16.50 - 2y

When bowling is 4 time then:

x + 4y = 28.50

Rewrite, x = 28.50 - 4y

Now solve both equations for the value of "y".

Thus, 16.50 - 2y = 28.50-4y

-2y + 4y = 28.50 - 16.50

2y = 12

y = 6

Insert y = 6 in the x - 2y = 16.50

x = 16.50 - 2y

x = 16.50 - 2 (6)

x = $4.5

Shoe rent is $4.5

Answer:

200%

Step-by-step explanation:

because 2000 is more than 1000 so the discount is 10% and 10% of 2000 is 200

Answer:

$1800

Step-by-step explanation:

100% = $2000

10% = $200

1% = $20

so, when there is a discount of 10%, then the corresponding $200 will be deducted from the price.

and the actual sales price of the couch is then

$2000 - $200 = $1800

little more practice to show the general thinking behind % :

let's say the discount is 18%. what now ?

well, we know how much 1% is. and we need then 18 times this 1% to deduct from the original price.

18% = 18 × 100%/100 or 100% × 18/100

so, for a couch of originally $2000 this is

18% = $2000 × 18/100 or $2000 × (1/100) × 18 or

($2000/100) × 18

whatever feels "nicer", but all of these approaches do the same thing and lead to the same result.

so, long story short :

18% = 18 × 1% = 18 × $20 = $360

and the sales price of the couch is then

$2000 - $360 = $1640

Answer:

50 people

Step-by-step explanation:

If you are to calculate the number of people that will come to the concert that will ensure option 1 and option 2 to yield equal amount

Let

x = number of people

Option 1:

Malcolm's Music Hall = 100 + 15x

Option 2:

Reggie's Reggae Room = 350 + 10x

Equate both options

100 + 15x = 350 + 10x

Collect like terms

100 - 350 = 10x - 15x

-250 = - 5x

x = -250/-5

x = 50 people

Answer:

y = 55

Step-by-step explanation:

Direct variation is

y = kx  where k is a constant

15 = k*9

15/9 =k

5/3 = k

The equation is y = 5/3 x

Let x = 33

y = 5/3 * 33

y = 55

Answer:

184

Step-by-step explanation:

First, note that the sides that are opposite to each other are congruent (this will come into play in a second). We can find the area of each triangle by doing 0.5(b)(h) (aka half * base* height). Since we've established tha opposite sides are congruent and the triangles are opposite to each other, they must be congruent. That means that the area is going to be the exact same for both triangles. So, we get the expression (0.5)(6)(4)(2), which comes out to 6*4 = 24. Then, to find the area of the 2 rectangles that are the sides, just do 5*10*2 = 100 square meters for both rectangles combines. Lastly, we need to find the area of the floor. The dimensions of the floor are 6 and 10, so we just do 6*10 = 60. Now, add all those numbers together. We get 100+60+24 = 184. Hope this helps! Let me know if anything is still confusing.

The transformation of a function may involve any change. The correct option is A.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Vertical shift

Stretching:

Given the function of f(x) as sin(x), Now it can be seen the graph of the two functions is parallel, but the function f(x) has a y-intercept of 0, while h(x) has a y-intercept of 1. Therefore, we can write,

h(x) = f(x) + 1

The function is shifted up by 1 unit.

Hence, the transformation of the function is correctly described in the first option.
