Step-by-step explanation:

The direction it travels is given by

arctan (y/x) =

arctan (-4/3) ≈ -53.13° ≈ 306.87°

Step-by-step explanation:

We are dealing with system of equations and can use graphing, elimination, or substitution. However, the equation is set up in a way such that it will be easier to use elimination. You can add the two equations and in doing so you will see the x and -x cancel out. The remaining equation is 2y = 0. So, y = 0. Substitute that into one of the equations and you get that x = 3. Therefore your answer is "D".

Answers

Answer:

x=-20

Step-by-step explanation:

1. Expand 3(x+8) : 3x+24

2.Expand -3(7-1/4x): -21*3/4x

3. 3x+24= -21*3/4x

4.Subtract 24 from both sides

3x+24-24= -21*3/4x-24

5.3x= 3/4x-45

6.Subtract 3/4 from both sides

3x-3/4= 3/4x-45-3/4

7.9/4x=-45

8.Multiply both sides by 4

9/4x*4=-45*4

9.9x=-180

10.Divide both sides by 9

9x/9=-180/9

11. x=-20

Please me mark me Brainliest!!!!!!!!!!!!!

Answer:

[tex]x = -20[/tex]

Step-by-step explanation:

Starting with:

[tex]3(x + 8) = -3(7 - \frac{1}{4}x)[/tex]

Use distributive property to multply 3 by X + 8

[tex]3x + 24 = -3(7-\frac{1}{4} x)[/tex]

Use distributive property to multiply -3 by 7 - 1/4x

[tex]3x + 24 = -21 - 3(-\frac{1}{4})x[/tex]

Express [tex]-3(\frac{1}{4} )[/tex] as a single fraction.

[tex]3x + 24 = -21 + \frac{- 3(-1)}{4}x[/tex]

Multiply -3 and -1 to get 3

[tex]3x + 24 = -21 + \frac{3}{4}x[/tex]

Subtract [tex]\frac{3}{4} x[/tex] from both sides

[tex]3x + 24 - \frac{3}{4}x= -21[/tex]

Combine 3x and [tex]-\frac{3}{4}x[/tex] to get [tex]\frac{9}{4} x[/tex]

[tex]\frac{9}{4} x + 24 = -21[/tex]

Subtract 24 from both sides

[tex]\frac{9}{4}x = -21 - 24[/tex]

Subtract 24 from -21 to get -45

[tex]\frac{9}{4}x = -45[/tex]

Multiply both sides by [tex]\frac{4}{9}[/tex], the reciprocal of [tex]\frac{9}{4}[/tex]

[tex]x = -45 * (\frac{4}{9})[/tex]

Express it as a single fraction

[tex]x = \frac{-45 * 4}{9}[/tex]

Multiply the top to get -180

[tex]x = \frac{-180}{9}[/tex]

Divide -180 by 9 and get -20

[tex]x = -20[/tex]

The graph shows the original giant on the left, and your scaled giant on the right, with the eyes, mouth, and sword scaled as you left them on the last screen.

Oh biscuits. Marcellus's mouth isn't proportional. Here's why:

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s mouth to be 5.46 times as wide as Dan’s mouth. A proportional giant would have the same multiple for both.

If Dan's mouth is 4 cm wide, how many centimeters wide should Marcellus's mouth be?

Answers

Answer: 21.84 cm
Explanation: It says “you dragged Marcellus’s mouth to be 5.46 times as wide as Dan’s mouth”. It also says that Dan’s mouth is 4 cm wide. If you multiply, Dan’s mouth (4 cm wide) by 5.46, then you get Marcellus’s mouth at 21.84 cm wide.

Estimate the area of the parallelogram

60 sq. units CAN SOMEONE PLZ HELP ASAP
68 sq. units
72 sq. units
84 sq.units

Answers

The answer would be 72 sq. units

Explanation: We can find the length of one side by using the pythagorean theorem (a^2 + b^2 = c^2). If we go to the center of the parallelogram, you can count the units to each corner. Since the length from the center to a corner is 6, and the length from the center to another corner 90 degrees away from the other one is 6, we can plug those in for “a” and “b”. So, 6^2 + 6^2 = c^2... 36+36=c^2... 72=c^2. Since “c” = the length of one side, and this parallelogram looks like a square, we can estimate that the area of the parallelogram is c^2 or 72 sq inches. I’m sorry if this was explained poorly! :)

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?

Answers

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle- a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.
