4x + 4 = 48

4x + 4 - 4 = 48 - 4

4x = 44

4x / 4 = 44 / 4

x = 11

Point B is located at (-4, -6). Where is the location of B’ after a reflection over the y-axis?
navik [9.2K]

Answer:

(4, -6)

Step-by-step explanation:

A reflection across the y-axis means the point is equal but opposite distance from the y-axis. It begins at 4 units to the LEFT (negative) of the y-axis, so after the reflection, it should be 4 units the the RIGHT (positive) of the y-axis. This has no change on the y-value of the point, because no matter the y-value, the point will still be the same distance from the y-axis. Long story short, if you're reflecting across the y-axis, change the sign of the x-coordinate. If you're reflecting across the x- axis, change the sign of the y-coordinate. That's why the answer is (4, -6).

Spencer buys a bag of 400 lollipops. Each lollipop has one of three flavors: cherry, watermelon, or grape. Spencer picks 15 loll
slavikrds [6]

Answer:

240 lollipops

Step-by-step explanation:

Cherry probability=9/15=3/5=0.6=60%.

\frac{3}{5} =\frac{x}{400}

5x=1200

x=240

240 of the lollipops should be cherry-flavored.

A particle starts at the point P=(−5,−1,3) when t=0 and moves along a straight line toward Q=(−6,−6,8) at a speed of 9 cm/sec. L
navik [9.2K]

Answer:

Step-by-step explanation:

Given

Particle moves from P\ (-5,-1,3)\ to\ Q\ (-6,-6,8)

speed of particle is v=9\ cm/s

Unit vector in the direction of vector \vec{PQ} is given by

\hat{n}=\frac{\vec{Q}-\vec{P}}{|\vec{Q}-\vec{P}|}

\hat{n}=\frac{-}{\sqrt{(-1)^2+(-5)^2+(5)^2}}

\hat{n}=\frac{}{\sqrt{1+25+25}}

Now Position of Particle at any time is given by

\vec{r(t)}=velocity\cdot time\cdot direction

\vec{r(t)}=9\cdot t\cdot \frac{}{\sqrt{1+25+25}}

Parametric vector equation is given by

x=\frac{-9t}{\sqrt{51}}

y=\frac{-45t}{\sqrt{51}}

z=\frac{45t}{\sqrt{51}}

What is StartFraction 3 pi Over 4 EndFraction radians converted to degrees? If necessary, round your answer to the nearest degre
Helen [10]

Answer:

135°

Step-by-step explanation:

To convert <em>Radians </em>to <em>Degrees</em>, you multiply the <em>Radians </em>amount by \frac{180}{\pi}.

Thus, we get \frac{3\pi }{4} * \frac{180}{\pi}

We then get \frac{540\pi }{4\pi }, which simplifies into 135 degrees.
