Answer:

C

Step-by-step explanation:

A=  x=0

B=  x=12

C=   x=2

Answer:

Suppose that you have an initial quantity A.

If you have an increase of X%, the new quantity (NQ) is written as:

NQ = A + A*(X%/100%) = A*(1 + X%/100%).

Now, if we have an increase of 2% then:

NQ = A*(1 + 2%/100%) = A*(1 + 0.02)

And no we have another increase of 1%, then:

NQ = (A*(1 + 0.02))*(1 + 1%/100%) = A*(1 + 0.02)*(1 + 0.01) = A*1.0302

The single decimal multiplier that you can use to increase by 2% followed by a 1% increase is 1.0302

Answer:

[tex] \sqrt{128} - \sqrt{72} = 2.82842712474619 \\ \\ 2.82842712474619 \div \sqrt{8 } = 1[/tex]

Answer:

a.

Step-by-step explanation:

His total earning including tips of 210.50 dollars is a.) $530.50

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, John waits on tables and is paid $8.00 an hour. In a 40-hour period,

∴ His earning in those 40 hours is,

= (40×8) dollars.

= 320 dollars.

He also earned 210.50 dollars in tips.

∴ His total earnings is,

= (320 + 210.50) dollars.

= 530.50 dollars.

Answer:

no this is because 28-8+9=29 and 20-9=11

Step-by-step explanation:

Answer:

Her equation is not balanced.

Because 28 - 8 + 9 = 20 - 9

                 29 = 11 ( its not balanced)

She put the  same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.

Answer:

Step-by-step explanation:

Let x be last year's salary.

100%x + 8/100 x = 40120

100x/(100) + 8/100x  = 40120

108x/100 = 40120

1.08x = 40120

x = 40120/1.08

x = 37148.14

Now if you take 8% of  37148.14        =    2971.85

And add it to                                            37148.14

You should get the current earning      40119.99  

You are within a penny of the same answer. This question will not work out evenly because 1.08 does not divide evenly into 40120.

Answer:

105°

Step-by-step explanation:

An angle is created by West First Street and South Main Street. Call this angle <1. m<1 = x, an unknown.

An angle is created by West First Street and North Main Street. Call this angle <2. This angle measures 30° less than <1, so it measures x - 30.

The two angles form a linear pair, so they are supplementary.

The sum of the measures of supplementary angles is 180 deg.

x + x - 30 = 180

2x - 30 = 180

2x = 210

x = 105

m<1 = 105

The angle we are looking for, created by North Main Street and East First Street is vertical to angle 1, so it is congruent to angle 1.

Answer: 105°

Answer:

A

Step-by-step explanation:

Cuando se tienen dos exponencial una dentro y otra fuera del paréntesis se suman debido a esto la A es la única que cumple con la ecuación

reflection and translation.

Given:

The different transformation in the options.

To find:

The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.

Solution:

In option 1,

[tex](x,y)\to (y,x)[/tex]

It represents reflection across the line y=x.

In option 2,

[tex](x,y)\to (x,-y)[/tex]

It represents reflection across the x-axis.

In option 3,

[tex](x,y)\to (4x,4y)[/tex]

It represents dilation by scale factor 4 and the center of dilation is at origin.

In option 4,

[tex](x,y)\to (x+2,y-5)[/tex]

It represents translation 2 units right and 5 units down.

We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.

So, the perimeter of the figure and its image are same in the case of reflection and translation.

But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.

Therefore, the correct option is 3.

Answer:

Step-by-step explanation:

you can look at the y=4x+9

1 4-9 or 4+9 o

2 4-9 = 5

3 5-4 = 9

The complete table of the values for the equation y = 4x + 9 is;

x   - 2    - 1    0      1      2      

y    1      5    9      13    17

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The equation is,

⇒ y = 4x + 9

Now,

Solve the equation for the values of x as;

The given values for x are;

x = - 2, - 1, 0 , 1 , 2

So, Find the value of y as;

Substitute x = - 2 in the equation we get;

⇒ y = 4x + 9

⇒ y = 4 × - 2 + 9

⇒ y = - 8 + 9

⇒ y = 1

Substitute x = -  in the equation we get;

⇒ y = 4x + 9

⇒ y = 4 × - 1 + 9

⇒ y = - 4 + 9

⇒ y = 5

Substitute x = 0 in the equation we get;

⇒ y = 4x + 9

⇒ y = 4 × 0 + 9

⇒ y = 0 + 9

⇒ y = 9

Substitute x = 1 in the equation we get;

⇒ y = 4x + 9

⇒ y = 4 × 1 + 9

⇒ y = 4 + 9

⇒ y = 13

Substitute x = 2 in the equation we get;

⇒ y = 4x + 9

⇒ y = 4 × 2 + 9

⇒ y = 8 + 9

⇒ y = 17

Thus, The complete table of the values for the equation y = 4x + 9 is;

x   - 2    - 1    0      1      2      

y    1      5    9      13    17

Answer: x=7 and AC = 44 unuts.

Step-by-step explanation:

We know that the diagonals of a parallelogram bisect each other. (i)

Here in parallelogram ABCD , AC and Bd are diagonals intersecting at E.

BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6

Using (i)

[tex]BE=\dfrac{BD}{2}\\\\2x+2=\dfrac{5x-3}{2}\\\\ 2(2x+2)=5x-3\\\\ 4x+4= 5x-3\\\\ 5x-4x=4+3\\\\ x= 7[/tex]

Now , AE = 4(7)-6 = 28-6 = 22

AC =2 AE = 2 (22) =44 units.

Hence, x=7 and AC = 44 unuts.

Step-by-step explanation:

Answer:

The value of [tex]a[/tex] is 6.

Step-by-step explanation:

Let the line be represented by [tex]3\cdot y = a\cdot x + 6[/tex], where [tex]x[/tex], [tex]y[/tex] are the independent and dependent variable, respectively. The explicit form of the formula is:

[tex]y = \frac{a}{3}\cdot x +2[/tex] (1)

To know the value of [tex]a[/tex], ,we need the values of [tex]x[/tex] and [tex]y[/tex] and solve the resulting expression: [tex](x,y) = (-3,-4)[/tex]

[tex]-4 = \frac{a}{3} \cdot (-3)+2[/tex]

[tex]-4 = -a + 2[/tex]

[tex]a = 6[/tex]

The value of [tex]a[/tex] is 6.
