Question 11:

Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false

Question 12:

A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection

Hence this statement is true

Question 13:

The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true

Answer:

Step-by-step explanation:

$5+\frac{1}{2} (14b-8)=-6$

$5+7b-4=-6$

$7b+1=-6$

$-1$ $-1$

$7b=-7$

$/7$ $/7$

$b=-1$

Answers in order:

7 + 7b - 4 = -6

7b + 1 = -6

7b = -7

b = -1

Hope this helps!

write the equation of the line that is parallel to y = 4x -7 and passes through the point (-2, -5). show your work.

natita [175]

Answer:

y = 4x + 3

Step-by-step explanation:

To do this, put the new line into the form y = mx + b where m is the slope and b is the y-intercept.

When two lines are parallel, they have the same slope. Since, the slope of the first line is 4, that means the slope of the second line is also 4.

So far, the equation is y = 4x + b.

Then, since you know (-2, -5) is a solution, x = -2, y = -5 is a solution so you can plug this into the equation.

This would be:

-5 = 4 * -2 + b

-5 = -8 + b

3 = b

This means the equation is y = 4x + 3.

PLS ANSWER QUICK! Thanks!

Answer:

The correct answer would be $a=\sqrt{c^2-b^2}$

Step-by-step explanation:

given $a^2+b^2=c^2$ we want to solve for a

How?

We can do this by using basic algebra ( isolating the variable (a ))

Step 1 subtract $b^2$ from each side

$a^2+b^2-b^2=a^2\\c^2-b^2=c^2-b^2$

now we have $a^2=c^2-b^2$

step 2 take the square root of each side

$\sqrt{a^2} =a\\\sqrt{c^2-b^2} =\sqrt{c^2-b^2}$

we're left with $a=\sqrt{c^2-b^2}$

Hence your answer is A
