On a coordinate plane, a straight line and a parallelogram are shown. The straight line has a negative slope and has a formula o

f y = negative x. The parallelogram has points G (negative 2, negative 3), F (1, negative 3), E (negative 1, negative 5), and H (2, negative 5).
What are the coordinates of the image of vertex F after a reflection across the line y = –x?

Answer:

B. (3, -1)

Step-by-step explanation: I got a 100 on the test

The rule for a reflection across line y = -x: (x, y) → (-y, -x)

F(1, -3) → F'(3, -1)

Which of the following methods would be the easiest to use to solve 12x2 – 48 = 0?
Katarina [22]

\bf \stackrel{\textit{solving for \underline{x}}}{12x^2-48=0\implies 12x^2=48\implies x^2=\cfrac{48}{12}\implies x^2=4} \\\\\\ x=\pm\sqrt{4}\implies x=\pm 2

I don’t know if i got the answer wrong but help!
Gwar [14]

Answer:

skew

Step-by-step explanation:

Perpendicular lines must intersect. In fact, they intersect forming right angles.

Lines AC and RC are not in the same plane and do not intersect.

They are called "skew lines."

Solve for x 6 ( x − 2 ) = 8 ( x − 9 )
valentinak56 [21]

Answer:

x = 30

Step-by-step explanation:

in order to solve for the value of x in the expression 6 ( x − 2 ) = 8 ( x − 9 )

we will first of all open the brackets and then evaluate for the value of x by combining the like terms.

from 6 ( x − 2 ) = 8 ( x − 9 )

6x -12 = 8x -72

combine the like terms

6x - 12 + 72 = 8x

-12 + 72 = 8x -6x

60 = 2x

divide both sides by the coefficient of x which is 2

60/2 = 2x/2

30 = x

x = 30

therefore the value of x in the expression 6 ( x − 2 ) = 8 ( x − 9 ) is equals to 30

The diagrams shows a 3cm x 5cm x 4cm cuboid.
Vera_Pavlovna [14]

Answer:

a) 5.83 cm

b) 34.45°

Step-by-step explanation:

a) From Pythagoras theorem of right triangles, given right triangle ABC:

AB² + BC² = AC²

Therefore:

AC² = 5² + 3²

AC² = 25 + 9 = 34

AC = √34

AC = 5.83 cm

b) From triangle ACD, AC = 5.83 cm, AD = 4 cm and ∠A = 90°.  

From Pythagoras theorem of right triangles, given right triangle ACD:

AD² + AC² = DC²

Therefore:

DC² = 5.83² + 4²

DC² = 34 + 16 = 50

DC = √50

DC = 7.07 cm

Let ∠ACD be x. Therefore using sine rule:

\frac{4}{sin(x)}=\frac{7.07}{sin(90)} \\ sin(x)=\frac{4*sin(90))}{7.07}=0.5657\\ x=sin^{-1}(0.5657)\\x=34.45^o
