It is 12:04 when she arrives at the library. Add 50 mins to equal 12:54. Then add 4 to equal 12:56. She leaves at 12:56.

Rani arrives at 12:04 so lets make it easier and make it 12:00. She spends 52 mins so add 52 to 12:00 which is 12:52. Now add the 4 mins from before and you get 12:56

linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4
RoseWind [281]

Answer:

  (c)  y-2 = -4(x-3)

Step-by-step explanation:

The point-slope equation of a line is ...

  y -k = m(x -h) . . . . . . line through point (h, k) with slope m

For (h, k) = (3, 2), and m = -4, the equation of the line is ...

  y -2 = -4(x -3)

Y = 2x^2
GarryVolchara [31]

Answer:

y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)

Step-by-step explanation:

all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)

If a is positive then the parabola opens up,

the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises

the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis

PLEASE NO LINKS, I will report you.
FromTheMoon [43]

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Help please this is for my homework that is due to tomorrow!!

The given polygons are similar

Step-by-step explanation:

By observing the given diagrams, we can see that the respective angles are congruent.

Two shapes are said to be similar if they have same shapes or one shape is created by uniformly increasing or decreasing the side of other.

For this purpose we find the scale factor of greater to smaller image, if the scale factor is same for each side then the two shapes are similar

So,

The scale factor is:

\frac{EF}{AB} = \frac{3}{1} = 3\\\\\frac{FG}{BC} = \frac{9}{3} = 3\\\\\frac{GH}{CD} = \frac{15}{5} = 3\\\\\frac{EH}{AD} = \frac{21}{7} = 3

We can see that the scale factor is same for all sides.

Hence,

The given polygons are similar
