Lines C and D are represented by the equations given below: Line C: y = x + 6 Line D: y = 3x + 2 Which of these shows the solution to the system of equations and explains why? (10 points)
A. (2, 8), because both lines pass through this point
B. (2, 8), because the point does not lie on any axis
C. (4, 14), because one of the lines passes through this point
D. (4, 14), because the point lies between the two axes

Answers

Answer 1

Answer:

C) y = x + 6

D) y = 3x + 2  We multiply C) by -1

C) -y = -x -6

D) y = 3x + 2

0 = 2x -4

x = 2

y = 8

Malaya is standing directly between a 90 foot tall courthouse and a 54 foot tall bank. If the angle of elevation from the point where Malaya is standing to the top of the courthouse is 72 degrees, while the angle of elevation to the top of the bank is 35 degrees. What is the distance between the courthouse and the bank? Show all your work to get credit!

Answers

Answer:

106.36 ft

Step-by-step explanation:

Let the distance from the point Malaya is standing to the courthouse be x and the distance to the bank is y

x + y is the distance between the courthouse and the bank

Then we have:

x/90 = cot 72° ⇒ x = 90 cot 72° = 90*0.3249196962 = 29.24 ft (rounded)y/54 = cot 35° ⇒ y = 54 cot 35° = 54*1.4281480067 = 77.12 ft (rounded)x + y = 29.24 + 77.12 = 106.36 ft

Answer:

106.3ft

Step-by-step explanation:

x= tan72=90/x

x= 90/tan 72

x= 29.2

y= tan35=54/y

y= 54/tan35

y= 77.1

x+y= answer

29.2 + 77.1 = 106.3

Answer:

  19.25 miles

Step-by-step explanation:

Antoine's rate before lunch was ...

  (5.25 mi)/(3 h) = 1.75 mi/h

Then his rate after lunch was ...

  2×(1.75 mi/h) = 3.5 mi/h

The distance he hiked after lunch was ...

  distance = speed × time

  (4 h)×(3.5 mi/h) = 14 mi

The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:

  5.25 mi + 14 mi = 19.25 mi

Given:

The equation is

To find:

The value of x.

Solution:

We have,

[tex]-4x^4+36x^3-80x^2=0[/tex]

It can be written as

[tex]-4x^2(x^2-9x+20)=0[/tex]

Splitting the middle term, we get

[tex]-4x^2(x^2-5x-4x+20)=0[/tex]

[tex]-4x^2(x(x-5)-4(x-5))=0[/tex]

[tex]-4x^2(x-5)(x-4)=0[/tex]

Using zero product property, we get

[tex]x^2=0,x-5=0,x-4=0[/tex]

[tex]x=0,x=5,x=4[/tex]

Therefore, the values of x are 0, 4 and 5.

ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution

Answers

Answer:

Substitution is when you isolate a variable-

3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).

4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).

how do u do this but in clear

Answers

Answer:

Look at the explanation :)

Step-by-step explanation:

Angle 2 and 3 are supplementary angles, which means they are equal.

Therefore, if

Angle 2 = 4x - 26

and

Angles 3 = 3x + 4,

It means that 4x - 26 = 3x + 4

Solve it,

4x = 3x + 30

x = 30

Input x to each angles,

Angle 2,

4(30) - 26 = 120 - 26 = 94

Angle 3,

3(30) + 4 = 90 + 4 = 94

Hope this helps :)

Answer: 9 13/28

Step-by-step explanation:

First turn your mixed numbers into improper fractions. 6 3/4 becomes 27/4 and 2 5/7 becomes 19/7. Now we need to make the denominators match. The least common multiple of 7 and 4 is 28. 27/4 becomes 189/28 and 19/7 becomes 76/28. We can now add these to get 265/28. This improper fraction can now be turned back into a mixed number. 28 will go into 265 evenly 9 times with 13 left over. Answer is 9 13/28
