The point 3/4 of the way from A(-4,- 7) to B(12, 5)

Answers

Answer:

The coordinates of C are (8,2)

Step-by-step explanation:

We are given the segment from A(-4,-7) to B(12,5) and it's required to find a point C(x,y) that is located at 3/4 of the distance from A to B.

This means that:

[tex]d_{AC}=3/4\cdot d_{AB}[/tex]

where dAC is the distance from A to C and dAB is the distance from A to B.

The same proportion of the distances is satisfied by the coordinates of the point C, that is:

[tex]\displaystyle x-x_A=\frac{3}{4}(x_B-x_A)[/tex]

Adding xA:

[tex]\displaystyle x=\frac{3}{4}(x_B-x_A)+x_A[/tex]

[tex]\displaystyle x=\frac{3x_B+x_A}{4}[/tex]

Similarily:

[tex]\displaystyle y=\frac{3y_B+y_A}{4}[/tex]

Calculating:

[tex]\displaystyle x=\frac{3(12)-4}{4}[/tex]

x = 8

[tex]\displaystyle y=\frac{3(5)-7}{4}[/tex]

y = 2

The coordinates of C are (8,2)

Answer:

[2] Division property of equality

Step-by-step explanation:

Given the equation, [tex] 4x - 6 = 34 [/tex], the following are steps and justification for each step taken:

[tex] 4x - 6 = 34 [/tex] => Given equation

Add 6 to both sides

[tex] 4x - 6 + 6 = 34 + 6 [/tex] => addition property of equality [1]

[tex] 4x = 40 [/tex] => simplify

Divide both sides by 4

[tex] \frac{4x}{4} = \frac{40}{4} [/tex] => Division property of equality [2]

[tex] x = 10 [/tex] => simplify

The justification for the steps taken are:

[1] Addition property of equality

[2] Division property of equality

Answer:

x is also 63 degrees this is because vertical angles are congruent or like equal in measure

Step-by-step explanation:

HOPE THIS HELPEDDDD

Answer:

63 degrees

Step-by-step explanation:

Since m is parallel to n, the angle that is marked 63 degrees and x are alternate interior angles. The alternate interior angle theorem states that alternate interior angles are congruent when a line cuts through two parallel lines. So, since m and n are parallel, these are congruent angles, making x also 63 degrees.

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given the graph of a function.

A function f(x) has the domain equal to the all values of x that the function is defined for.

Range of the function is the set of all the values of the function for the x in the domain.

Here, the function values are from infinity to -3 and then again mover from -3 to infinity.

So the range consists of all the real numbers from -3.

Hence the range of the function is the set of all real numbers from -3.

What is the value of x

Answers

Answer:

x=39

Step-by-step explanation:

First I try to find the angle measurements for the rest of the angles inside the triangle. I saw that the 68 degrees and I notice that it was vertical angles, meaning that the inside is also 68. I then notice that the 107 and the other unknown angle besides x must be 180 when adding up, so I can do 180-107=73. Now I know that that angle is 73 degrees I can find x by solving this equation 180=73+68+x, which the answer comes out to be 39. so x=39.

pls mark brainlest

Hello!!!

Your answer would in fact Be 24 the steps are super simple what may confuse you is the v it is quite confusing but v is basically a variable that signifies multiplication as it is together with the 4 but this here is an expression because it has nothing equal to it so we have no answer to define what the v is! Also a tip is whenever a number has parenthesis and a number is outside of the parentheses without any sign that signifies multiplication :)!! So as of now if your not learning how to find variable answers then you can basically pretend the v is not needed but have a nice day and I really hope this has helped you!! I have spent quite a while typing this so I hope this is all worth it!!

To take 25% off, you want to do 1-.25 which equals .75. That means that you have to pay 75% of the cost after the 25% off discount.

Multiply the cost, 150, by .75 to find the new price after the discount.
150x.75=112.5

The price is now $112.50
