Answer:

Step-by-step explanation:

The point (7, 0) becomes the point (7, 0) when reflected over the x-axis. That is, its coordinates do not change.

The point (7, 0) lies on the x-axis, so is on the line of reflection. Any point on the line of reflection is invariant--it doesn't move.

__

The transformation for reflection in the x-axis is ...

  (x, y) ⇒ (x, -y)

  (7, 0) ⇒ (7, 0) . . . . . . the opposite of 0 is 0

Answer: 5(b+3) is b = 3

Step-by-step explanation:

1)     5(b+3)      - distribute

2)     5b = 15    

3)     [tex]\frac{5b}{5} =\frac{15}{5}[/tex]     - divide

4)      b = 3       - solution

Step-by-step explanation:

The sides of triangle are 5,12 and 13

Here, the greatest side is 13

Therefore,

Hence, these sides will form a right angled triangle.

[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]

To check if the triangle is congruent or not, we have to see if they form Pythagorean triplet, that is :

sum of squares of smaller sides should be equal to square of the longest side.

let's check it out ~

[tex]\qquad \sf  \dashrightarrow \: {5}^{2} + 12 {}^{2} = {13}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: {25}^{} + 144 = 169[/tex]

[tex]\qquad \sf  \dashrightarrow \: 169= 169[/tex]

Therefore, the sides 5, 12 and 13 forms a right angle.

Answer:

17/18

Step-by-step explanation:

okay this one is a bit different

you have to take the total number that are batwing-shaped (12) and the total number that are made of cotton (12) and then subtract the ones that are both batwing-shaped and made of cotton.

so 12+12-7 which is 17

then you put that over the total (18)

17/18 doesn't simplify

Answer:

5 miles

Step-by-step explanation:

We will use the method of cross multiplying and dividing.

You will multiply 60 x 3

Then, take the answer (180) and divide it by 36.

That will give you 5 and your answer.

Answer:

A

Step-by-step explanation:

y = a f(x)

If |a| > 1 then a f(x) is f(x) stretched vertically by scale factor of a

If 0 < |a| < 1 then f(x)  is squashed vertically

If a < 0 then f(x)  is also reflected in the x-axis

y = f(ax)

If |a| > 1 then f(ax) is f(x) squashed horizontally by a scale factor of a

If 0 < |a| < 1 then f(x)  is stretched horizontally

If a < 0 then  f(x) is also reflected in the y-axis

g(x) has been squashed vertically by a scale factor of 1/3 (green on the attached diagram) and then reflected in the x-axis (red on the attached diagram)

Therefore, the solution is [tex]g(x) = -\dfrac13f(x)[/tex]

A rational number is defined as a number that can be written as a fraction and a number that terminates.

An irrational number is defined as a number that can't be written as a fraction and a number that has no end.

Step-by-step explanation:

4/7 is irrational because, in decimal form, it is 0.57142857...

Square root of 30 is also irrational because the square root is 5.47722557...

21 divided by square root of 4 is rational because square root of 4 is 2 and 21 divided 2 is 10.5.

pi is irrational because, in decimal form, it is 3.14159265....

Answer:

The answer is 1,657.5 miles

Step-by-step explanation:

First divide 510 by 20 510 ÷ 20 = 25.5 into 65 = 1657.5

Given that test of a new car results in 510 miles on 20 gallons of gas. By unitary method, you can drive miles on 65 gallons of gas.

Unitary method is a method of solving a problem wherein to find the value of k units, you first calculate the value of one item, then multiply the value of the one item to k.

Given in the question,

distance covered in 20 gallons of gas  = 510 miles

distance covered in 1 gallons of gas  = [tex]\frac{510}{20} = 25.5[/tex] miles

distance covered in 65 gallons of gas = 25.5 * 65 miles = 1657.5 miles
