NEED HELP WITH SLOPE

Answers

take two points

(2,4)(-3,-3)

Slope

m=y2-y1/x2-x1m=-3-4/-3-2m=-7/-5m=7/5

Answer:

[tex]m=\dfrac{7}{5}[/tex]

Step-by-step explanation:

To find the slope of a line, find two points on the line and define them as follows:

[tex]\textsf{let}\:(x_1,y_1)=(-3,-3)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(2,4)[/tex]

Substitute the points in the slope formula and solve for m:

[tex]\begin{aligned}\textsf{slope}\:(m) & =\dfrac{y_2-y_1}{x_2-x_1}\\\\ & =\dfrac{4-(-3)}{2-(-3)}\\\\ & = \dfrac{4+3}{2+3}\\\\ & = \dfrac{7}{5}\end{aligned}[/tex]

Therefore, the slope of the given line is [tex]\dfrac{7}{5}[/tex]

Answers

I suggest answer A. 110 and 109
Reason
Using theory that all angles combined will equal 360

Using theory of alternate interior angles, using 110 means alternate interior will be 110. To complete the angle the other side is 70 for the 180 degree angle.
Doing the same thing on the other side using 109 and 71 = 180

NO LINKS!!! For each below, tell whether the table represents a linear, exponential, inverse or no relationship. Write an equation for each table (if possible).​

Answers

Answer:

[tex]\large \boxed{\sf y = (x - 2)^2 - 4}[/tex]

[tex]\large \boxed{\sf Quadratic \ Function}[/tex]

Explanation:

A linear function shall increase linearly. Here due to mass differences between points, it is visible that it is not a linear function.

There is a better way to understand what type of equation it is after plotting the coordinates on the graph.

Look at the attachment!

After looking so, we can determine this as quadratic function.

** Not a exponential, inverse, linear function **

To find equation:

Quadratic function: y = a(x - h)² + k

Locate (h, k) = (2, -4)

Take any other suitable point for example = (0, 0)

Insert values to find (a),

a(0 - 2)² - 4 = 0

4a = 4

a = 1

Now Join together: y = 1(x - 2)² - 4   --- Quadratic Equation

Exponential

It should be a parabola

The best shortcut trick is the fact about the parabola is that parabola is symmetric and axis of symmetry goes through vertex

So on both sides of vertex i e same distance on x from vertex the two x values have same y value .

Observe the table and find similar y values

(0,0) and (4,0)(1,-3) and (3,-3)

FIND midpoint of x which is axis of symmetry

0+4/2=21+3/2=2

We have been sured axis of symmetry is at x=2

Vertex (2,-4)

Form equation

y=a(x-h)²+ky=a(x-2)²-4

Put (5,5)

5=a(5-2)²-45=a(3²)-49a-4=59a=9a=9

Final equation

y=(x-2)²-4

It is in vertex form so:

225 m. Find its area.

Answers

First step:
Add up all the parts in the ratio:
2 + 3 + 4 = 9

Second step:
Do 225 divided by 9, this helps you get the value of each part:

225 divided by 9 = 25

Third step:
Find the value of each ratio sector, this is done by doing:

2 times 25 = 50
3 time 25 = 75
4 times 25 = 100

Last step:
Area:
75 times 50 = 3750

Final answer is 3750.

So

PQ=TU=12<R=<V=75<Q=180-(45+75)=60°=<UUV=QR=10TV=PR=7m<T=m<P=45

Answer:

[tex]\sf \overline{PQ}=12[/tex]

[tex]\sf \overline{UV}=10[/tex]

[tex]\sf \overline{TV}=7[/tex]

[tex]\sf m \angle T=45^{\circ}[/tex]

[tex]\sf m \angle R=75^{\circ}[/tex]

[tex]\sf m \angle Q=60^{\circ}[/tex]

[tex]\sf m \angle U=60^{\circ}[/tex]

Step-by-step explanation:

≅ sign means that the triangles are congruent, which means they both have the same shape and the same size.

When comparing congruent shapes, inspect the order in which the vertices are given in the statement.

Therefore, if ΔPQR ≅ ΔTUV then:

[tex]\sf \overline{PQ} \cong \overline{TU}[/tex][tex]\sf \overline{QR} \cong \overline{UV}[/tex][tex]\sf \overline{PR} \cong \overline{TV}[/tex]

Similarly:

[tex]\sf m \angle P \cong m \angle T[/tex][tex]\sf m \angle Q \cong m \angle U[/tex][tex]\sf m \angle R \cong m \angle V[/tex]

Therefore, from inspection of the triangles:

[tex]\sf \overline{PQ} \cong \overline{TU}=12[/tex]

[tex]\sf \overline{UV} \cong \overline{QR}=10[/tex]

[tex]\sf \overline{TV} \cong \overline{PR}=7[/tex]

[tex]\sf m \angle T \cong m \angle P=45^{\circ}[/tex]

[tex]\sf m \angle R \cong m \angle V = 75^{\circ}[/tex]

The sum of the interior angles of a triangle is 180°, therefore:

[tex]\sf m \angle Q \cong m \angle U=180^{\circ}-45^{\circ}-75^{\circ}=60^{\circ}[/tex]

Step-by-step explanation:

SINCE THE LINES ARE PARALLEL THEN ANGLE A AND ANGLE B ARE COREESPONDING TO EACH OTHER.A = 7x + 24 B= 3x+ 92A=B7x + 24 = 3x + 92

7x - 3x = 92 - 24

4x = 68

x = 68 / 4

x =17

Answer:

143

Step-by-step explanation:

These are corresponding angles meaning they are congruent. So we just have to set them equal to each other and solve for x. Then plug in x.

7x + 24 = 3x + 92

subtract 3x from both sides

4x + 24 = 92

subtract 24 from both sides

4x  = 68

divide both sides by 4

x = 17

Now plug in x to angle A, which is 7(17) + 24

119 + 24

then add

you get:
