I need the answer thank you!

Answer:

5 units

Step-by-step explanation:

the formula is delta y over delta x.

The distance between -2 and -2 is 0

The distance between 6 and 1 is 5

So, it's 5 units.

Hope this helps :)

Answer:

2x + y = -5 (which is Answer 1).

Step-by-step explanation:

The possible answer choices are all versions of the standard equation of a straight line:   Ax + By + C = 0.  If A and B are both positive, as they are here, then the slope is negative and has the form m = -A/B.  Only the first answer choice passes here:  with +2x and +1y, the slope is -2.  This automatically eliminates the other possibilities.

Looking at the first answer choice, we see that A must be 2 and B must be 1

so that the slope is m = -2.    Writing out this equation:  Ax + By + C = 0.

Replace A with 2 and B with 1:  2x + y + C = 0.

Finally, replace x with -1 and y with -3:  2(-1) + (-3) + C = 0.

Solving this for C, we get   -2 - 3 + C = 0, or -5 + C = 0, or C = 5.

We end up with 2x + y = -5 (which is Answer 1).

Answer:

B. Simplify both sides of the equation to get [tex]a^2 + 2ab + b^2 - c^2 = 2ab[/tex]; then subtract 2ab and add [tex]c^2[/tex] to both sides of the equation

Step-by-step explanation:

Given

[tex](a + b)^2 - c^2 = 4(\frac{1}{2}ab)[/tex]

Required

Describe the next steps to

First, we open all brackets

[tex](a + b)^2 - c^2 = 4(\frac{1}{2}ab)[/tex]

[tex](a + b)(a + b) - c^2 = 4(\frac{1}{2}ab)[/tex]

[tex]a^2 + 2ab + b^2 - c^2 = 4 * (\frac{1}{2}ab)[/tex]

[tex]a^2 + 2ab + b^2 - c^2 = 2ab[/tex]

At this point, options A and C are incorrect because they didn't present the right result of the expression.

So, we have options B and D to consider

The next step is to subtract 2ab from both sides

[tex]a^2 + 2ab + b^2 - c^2 - 2ab = 2ab - 2ab[/tex]

Collect like terms

[tex]a^2 + b^2 - c^2 +2ab - 2ab = 2ab - 2ab[/tex]

[tex]a^2 + b^2 - c^2 = 0[/tex]

Lastly, to prove the Pythagoras theorem, the equation has to be in form of[tex]a^2 + b^2 = c^2[/tex]; meaning the [tex]c^2[/tex] is added to both sides; See below

[tex]a^2 + b^2 - c^2 = 0[/tex]

Add [tex]c^2[/tex] to both sides

[tex]a^2 + b^2 - c^2 + c^2= 0 + c^2[/tex]

[tex]a^2 + b^2 = c^2[/tex]

At this point, only option B completes Kira's proof

Answer:

C (148)

Step-by-step explanation:

All numbers divisible by 3:

The numbers equal to something divisible by 3

ex:

138=

1+3+8= 12 which is divisible by 3, so 138 is divisible by 3

Answer:

138

Step-by-step explanation:

We know that if the sum of the numbers that make up 138 is divisible by 3, then 138 is divisible by 3. Note: If you divide 138 by 3, you get 46 which is a whole number.

Answer: 97ft

Step-by-step explanation:

Using pythagorean's theorem.

[tex]c^2=a^2+b^2\\c=\sqrt{a^2+b^2}[/tex]

where;

a and b are the sides.

[tex]c=\sqrt{(65ft)^2+(72ft)^2}\\ c=\sqrt{4225ft^2+5184ft^2}\\ c=\sqrt{9409ft^2}\\ c=97ft[/tex]

Answer:

the answer of the expression is 190

Step-by-step explanation:

Given expression as :

20 % of 950

Or, [tex]\frac{20}{100}[/tex] times 950

Or, [tex]\frac{20}{100}[/tex] × 950

Or, 20 × [tex]\frac{950}{100}[/tex]

or, 20 × 9.5

∴ 190

Answer:

1/5 times 950

Answer:

x = 9, x = 3

Step-by-step explanation:

Given

y = [tex]\frac{x-3}{x^2-12x+27}[/tex]

The denominator of the rational function cannot be zero as this would make y undefined.

Equating the denominator to zero and solving gives the values that x cannot be, that is

x² - 12x + 27 = 0

(x - 9)(x - 3) = 0

Equate each factor to zero and solve for x

x - 9 = 0 ⇒ x = 9

x - 3 = 0 ⇒ x = 3

Thus x = 9, x = 3 are excluded values and the points of discontinuity

Answer:

If linear relations have equal coefficient about the independent variable, then those linear relations are parallel. For example, [tex]y=3x+4[/tex] and [tex]y=3x-5[/tex].

Notice that the coefficient of the dependent variable must be also equal, otherwise it would change the slope of the expression and they wouldn't be parallel.

The statement is not false.

An improvemente would be that the constant term no need to be equal too, between linear relations, because they can be at "differecent heights", sort of speak.

Answer:

A.) Extending the line of multiple of scale factor r on two corresponding vertex

B.) Scale factor r = 2.5

C.) A'B'/AB = 5/2

Step-by-step explanation:

A.) To find the centre O, take a corresponding vertex of the two shapes. Draw a line passing through the the vertex and extending beyond the initial one. The length of the line must be multiplied by the scale factor r

The center of a dilation is a fixed point in the plane in which all points are expanded or contracted.

B.)  If AB=6 mm and A'B'= 15mm,

The scale factor r = 15/6 = 5/2 = 2.5

C.) A'B'/AB = 5/2

Answer:

x is 24 degrees

Answer:

x = 24

Step-by-step explanation:

I'm 8 years old and I know how to do this.

The sum of interior angles of a quadrilateral is 360°

The sum of a supplementary angle is 180°

180 - 111 = 69

94 + 41 + 69 + a = 360

204 + a = 360

a = 156

156 + x = 180

x = 24

Answer: choices 1 and 4

Step-by-step explanation:

A central angle is the angle that forms when two radii meet at the center of a circle. So the answers are the ones with point D in the middle.
