Which equation represents the horizontal line passing through (7.5) ?
A.x= 5
B.x = 7
C.y = 7
D.y = 5

Answers

Answer 1
Horizontal line is y=, because every point along that horizontal line will have the same y value. So, now look at the point and notice that the y value is 5. So the horizontal line with a y value of 5 is y=5. Thus the answer is f.
Answer 2

y=5

I think it’s c?

Answers

the answer is b) i think

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

Step-by-step explanation:

Label the points from A-F. I attached an image of how I labeled the points.

Notice that there are similar triangles here:

[tex]\triangle ABD \sim \triangle FED[/tex][tex]\triangle ACD \sim \triangle AEF[/tex]

Set up proportions to find the values of x, y, and z.

[tex]\displaystyle \text{Equation I: }\frac{FD}{AD} = \frac{FE}{AB}[/tex][tex]\displaystyle \text{Equation II: } \frac{A F}{AD}=\frac{EF}{CD}[/tex]

Let's make this problem simpler by incorporating only 2 variables instead of 3.  Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.

Substitute known values or variables into the proportions.

[tex]\displaystyle \text{Equation I: } \frac{d-y}{d} = \frac{x}{6}[/tex][tex]\displaystyle \text{Equation II: }\frac{y}{d}= \frac{x}{12}[/tex]

Cross-multiply and simplify Equation I.

[tex]6(d-y)=dx[/tex] [tex]6d-6y=dx[/tex]

Cross-multiply and simplify Equation II.

[tex]12y=dx[/tex]

We now have two equations that are equal to dx, so we can set them equal to each other.

[tex]6d-6y=12y[/tex]

Add 6y to both sides of the equation.

[tex]6d=18y[/tex]

Divide both sides of the equation by 6.

[tex]d=3y[/tex]

We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.

[tex]\displaystyle \frac{y}{3y} = \frac{x}{12}[/tex]

Cross-multiply and simplify the equation.

[tex]12y=3xy[/tex]

Divide y from both sides of the equation.

[tex]12=3x[/tex]

Divide both sides of the equation by 3.

,

,

Explanation:

In a parallelogram, there are only two sizes of angle - two are acute and two are obtuse.

Opposite angles are equal .

Consecutive angles are supplementary because they are co-interior angle on parallel lines.

An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.

Let one angle be  

x

The size of the other angle is given by  

9

x

30

2

x

+

2

(

9

x

30

)

=

360

   

sum of the angles is 360°

2

x

+

18

x

60

=

360

20

x

=

420

x

=

21

°

The obtuse angles are each  

180

21

=

159

°

The other option where the given angle is the opposite angle is described is well explained by Alan P.

Step-by-step explanation:

The interior angles of the parallelogram are 21° and 159° respectively.

What is parallelogram?

A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.

In a parallelogram opposite interior angles are equal and the angles on the same side of the traversal are supplementary (i.e) 180°

For the given situation,

The measure of one interior angle be [tex]x[/tex] and

Another angle was given as [tex]9x-30[/tex]°  

⇒[tex]x+9x-30[/tex]°[tex]=180[/tex]°

⇒[tex]10x=180[/tex]°[tex]+30[/tex]°

⇒[tex]10x=210[/tex]°

On dividing [tex]10[/tex] on both sides,

⇒[tex]\frac{10x}{10}=\frac{210}{10}[/tex]

⇒[tex]x=21[/tex]°

So, another angle is [tex]9x-30[/tex] = [tex]9[/tex]×[tex]21-30[/tex]

⇒[tex]189-30[/tex]

⇒[tex]159[/tex]°

Hence we can conclude that the interior angles of the parallelogram are 21° and 159°.
