If you observe the two given equations, the left hand side of both equation is the same and is equal to y.

Since the left hand side of two equations is the same, we can conclude that the right hand side of two equations must also be the same.

So, setting them right hand sides of both equations equal to each other and solving for x, we can find the solution to the simultaneous equations.

Therefore, the correct answer is option B

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are

tankabanditka [31]

The coordinates of point B' are (-3, 6).

<h2>Given that</h2>

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).

The triangle is translated as 3 units to the left and 1 unit up.

<h3>We have to determine</h3>

What are the coordinates of B' after the translation?

<h3>According to the question</h3>

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).

The triangle is translated as 3 units to the left and 1 unit up.

To find the coordinates of B', we will shift the x-coordinate of point B to left by 3 units and the y-coordinate of point B to 1 unit up.

After the given transformation the coordinates of point B' would be:

$\rm B(0, \ 5) = B (0-3, \ 5+1) = B(-3, \ 6)$

Therefore, the coordinates of point B' are (-3, 6).

Find the value of r so the line that passes through each pair of points has the given slope.

padilas [110]

Answer:

Step-by-step explanation:

( 3 - r ) / ( 1 + 5) = 7/6

$\frac{3-r}{1+5}$ = $\frac{7}{6}$ ⇒ 3 - r = 7 ⇒ r = <em>- 4</em>

See question in attached photo.<br>Answer question 4b and 5c

sdas [7]

9514 1404 393

Answer:

4b: 8.6 m/s²; 1.3×10^5 N; 2.1×10^4 N decrease

5c: -1.6×10^12 J; -1.6×10^12 J

Step-by-step explanation:

i) The acceleration due to gravity is inversely proportional to the square of the distance between the objects. The distance to the shuttle is ...

1 + (5×10^5)/(6.4×10^5) = 69/64 . . . times the radius of the earth

Then the acceleration due to gravity at the height of the space shuttle is about ...

(10 m/s²)(64/69)² ≈ 8.6 m/s²

ii) The weight of the space shuttle at that height is about ...

F = ma = (15000 kg)(8.6 m/s²) ≈ 1.3×10^5 N

iii) The loss of weight will be ...

ΔF = m(a1 -a0) = (15000 kg)(10 m/s² -8.6 m/s²)

= 1.5×10^4×1.4 N = 2.1×10^4 N

____

i) The gravitational potential energy is given by ...

U = -GMm/r

where M and m are the mass of the earth and the rocket, respectively.

U = -(6.67×10^-11)(6.0×10^24)(2.5×10^4)/(6.4×10^6) ≈ -1.6×10^12 J

ii) At a height of 3×10^4 m, the denominator in the above expression changes from 6.4×10^6 to 6.43×10^6. This changes the gravitational potential energy by a factor of 6.4/6.43 to -1.6×10^12 J

(Note: we're carrying only 2 significant figures in the result in accordance with the rules for precision in such calculations. The change is noticeable at the level of the 4th significant figure, less than 1/2%.)

Solve for xx. Round to the nearest tenth of a degree, if necessary.

Tanya [424]

Answer:

56.6 °

Step-by-step explanation:

For a RIGHT triangle cos (x ) = adjacent leg / hypotenuse

cos (x) = 4.4 / 8

arc cos (4.4/8) = 56.63 ° = ~ 56.6°
