Answer:

x=5 and y=6

Step-by-step explanation:

Step: Solve 3x−7y=−27 for x:

3x−7y=−27

3x−7y+7y=−27+7y

3x=7y−27

[tex]\frac{3x}{3} =\frac{7y-27}{3}[/tex]

[tex]x=\frac{7}{3} y-9[/tex]

Step: Substitute   [tex]\frac{7}{3}y-9[/tex] for x in 6x−5y=0:

6x−5y=0

[tex]6(\frac{7}{3}-9)-5y=0[/tex]

9y−54=0

9y−54+54=0+54

9y=54

[tex]\frac{9y}{9} =\frac{54}{9}[/tex]

Therefore y=6.

Step: Substitute 6 for y in x= [tex]\frac{7}{3} y-9[/tex]:

[tex]x=\frac{7}{3} y-9[/tex]

[tex]x=\frac{7}{3}(6)-9[/tex]

Therefore x= 5.

x= 5 and y= 6

Answer:

28/45

Step-by-step explanation:

tan = opp/adj

tanE = 28/45

#10.

If the two triangles are similar, then their sides are proportional.

EC we know immediately. If the whole side BC = 12 = BE + EC, and BE is 4, then EC = 8.

Therefore, I can say that BD / (BD + DA) = BE / (BE + EC). To solve the problem for side DA, x will be used in place of DA.

8 / (8 + x) = 4 / (4 + 8)

8 / (8 + x) = 4 / 12 || Cross-multiply

4(8 + x) = 12 * 8

32 + 4x = 96

4x = 64

x = 16

AD = 16

Then, if we know AD, we can easily find AB. AB = AD + DB. AB = 24.

Lastly, we need to find AC. All of the other lengths on the big triangle have been double that of the smaller triangle, so 6 x 2 = 12. AC = 12.

#11.

BC will be parallel to DE if the proportions are equal.

AE / AB = AD / AC

1 / 5 = 2 / 11

These fractions are not equivalent, therefore BC and DE are not parallel.

Step-by-step explanation:

A diameter is a chord.It is the longest chord.

Answer:

7

Step-by-step explanation:

As we can see, the sides of the bigger triangle is twice that or the smaller

Thus, we have it that for similar sides, we simply have to multiply the smaller side length by 2 to give the larger

We have this as:

2(2y + 5) = 5y + 3

4y + 10 = 5y+ 3

5y-4y = 10-3

y = 7

Answer:

I think no A. x = -1/2 ,x = -4

Answer:

A.m = -3

Step-by-step explanation:

This equation is written in point slope form

y-y1 = m(x-x1)

y +2 = -3(x – 7)

y - -2 = -3(x – 7)

The slope is -3 and the point is (7, -2)

Answer:

$10.50

Step-by-step explanation:

First, find the cost of a pound of nuts.

Divide the price by the number of pounds:

60/4

= 15

Calculate the price with the 30% discount by multiplying this by 0.7:

15(0.7)

= 10.5

So, after the discount, a pound of nuts will cost $10.50

Answer:

Step-by-step explanation:

The proof of the right-triangle is: [tex]a^{2} + b^{2}=(c)^{2}\\[/tex].

To prove that [tex]a^{2} + b^{2}=(c)^{2}\\[/tex].

The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:

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

Given that:

To proof:

The proof of the right-triangle is:

[tex]a^{2} + b^{2}=(c)^{2}[/tex]

from question it is given that

c=e +f

By Pythagoras theorem, we have:

[tex]a^{2} + b^{2}=(f+ e)^{2}[/tex]

Therefore, the proof of the right-triangle is:
