Answer:

Step-by-step explanation:

The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.

The transformation of 3 is a dilation by a factor of 3, so is non-rigid.

The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.

Answer:

(3V)/A = h

Step-by-step explanation:

V = 1/3 Ah

Solve the literal equation using inverse operations;

V = 1/3 Ah

*3    *3

3V = Ah

/A     /A

(3V)/A  = h

Answer: 90,75. cos 55°. sin55° ≈ 42,64

through E, draw EK perpendicular to BC (F ∈ BC)

because E is the midpoint of AB => BE = 11/2 = 5.5

ΔBEF is a right triangle at K

=> sin 55° = EK/BE

=> EK = 5,5.sin 55°

ΔABC has E and F is the midpoints of AB and AC

=> EF is  the median line of the triangle

=> EF = 1/2.BC

through A, draw AD perpendicular to BC

=> ΔABD is a right triangle at D

=> BC = 11.cos 55°.2 = 22.cos 55°

=> EF = 11.cos 55°

=>the area of the trapezium BEFC is:

[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

Answer:

Ok so we see that at the end there is a +2 so the first thing we want to do is start our first point at (0,2). After that we can see that our slope is -1/2, since slope equals x/y we know that it is asking us to go 1 to the right, however since it is negative we will be going 2 down.  the Y intercept is the point where the line intercepts the Y-axis which is (0,2)

Step-by-step explanation:

Answer:

slope= -1/2

y-intercept = (0,2)

Step-by-step explanation:

The y-intercept is what y equals when x equals zero. On the graph, it is where the graph crosses through the y axis.

To find the y-intercept, plug in 0 for x, so x = 0

y = -1/2 (0) + 2

y=2

and we know x =0

So the point is (0,2)

Answer:

Step-by-step explanation:

57 / 514

=   57 / 514

(Decimal: 0.110895)

Rewrite the equation as  

x /14 =  5/ 7 .  x/ 14 =  5/ 7

Multiply both sides of the equation by  

14.14  ⋅  x /14 =  14 ⋅ 5 /7

Simplify both sides of the equation.

Tap for fewer steps...

Cancel the common factor of  14 .  

Cancel the common factor.

14 ⋅  x /14 =  14 ⋅ 5 /7

Rewrite the expression.

x = 14 ⋅ 5 /7

Simplify  14 ⋅  5/ 7 .

Cancel the common factor of  7 .

Factor  7  out of  14 .

x = 7 ( 2 ) ⋅ 5/ 7

Cancel the common factor.

x = 7 ⋅  2 ⋅  5/ 7

Rewrite the expression.

x  = 2 ⋅ 5

Multiply  2  by  5 .

x = 10

Answer:

4 3/2 is simplified into 5 1/2

Step-by-step explanation:

There are three halves in the improper fraction 3/2. Two of those halves make another whole number, and you are left with one half and 1. 4 + 1 1/2 is equal to 5 1/2.

Answer:y= -9x-25

Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).

--------

Form:: y = mx + b

Solve for "b"::

-7 = -9*-2 + b

-7 = 18 + b

b = -25

-----

Equation:

y = -9x - 25

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

Cheers,

Stan H.

-----------

point slope formula

y-y1=m(x-x1)

y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.

y+7=-9x-18

y= -9x-25

Answer:

The area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²

Step-by-step explanation:

The Area is basically a measure of how much space in square units there is inside an object.

As the shape is shown on the centimeter grid.

We also know that If the scale factor > 1, the image is enlarged.

As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.

The area of original shape = 5 cm²

The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²

Thus, the area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²

Step-by-step explanation:

Answer:

f(-2) = 50

Step-by-step explanation:

f(x) = 8x^2 - 14x - 10, find f(-2)

Just like how -2 replaced x in f(x), you will replace x with -2 in the equation

f(-2) = 8(-2)^2 - 14(-2) - 10

f(-2) = 8(4) + 28 - 10

f(-2) = 32 + 18

f(-2) = 50

Answer:

70

Step-by-step explanation:

70 percent of 100 is [tex]\frac{70}{100}[/tex]

so [tex]\frac{70}{100}[/tex] × 100 students

= 70 students

Answer:

Rational

Step-by-step explanation:

We first have to define what these numbers mean:

Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.

Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.

An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....

Integers are real numbers that are whole numbers.

Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.

Answer:

x=7

Step-by-step explanation:

First, add 15 to both sides (whatever you do to one side, do it to the other), this will help cancel out the -15 on the right side of the equation,  

so 9x-15+15=7x-1+15,      the 15 cancels out and we get 9x=7x+14

Now we want to simplify this further, lets subtract 7x from both sides,

9x-7x=7x-7x+14,     2x=14

Let's divide both sides by 2 because the 2 and x are held together by "multiplication" so we will break that bond with division and that will leave us with x.

2x/2=14/2

x=7

Our goal is to have a variable on one side and a number on the other, so that is why we are doing this. Also, notice that to solve this equation we were doing the reverse operation. For example, when we added 15 to both sides, we were performing the opposite of subtraction because we had a -15. Remember that variables are connected to numbers through multiplication, so 9x would be the same thing as 9*x

Answer:

Step-by-step explanation:

If N is the midpoint of CD, it means that N bisects the line CD. Hence;

CN + ND = CD .... 1 and;

CN = ND .... 2

Substitute equation 2 into 1;

CN + CN = CD

2CN = CD

Rearrange;

CD = 2CN (proved)
