Quadrilateral FRIO is the result of a reflection of quadrilateral LAMB over the y-axis. FRIO has vertices at F(-7,6), R(1,7), I(

andrew11 [14]

Answer:

F' = (7, 6)

R' = (-1, 7)

I' = (-2, -5)

O' = (6, -6)

Step-by-step explanation:

The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.

Hazel needs to get to her granddaughter's house by taking an airplane and a rental car. She travels 900 miles by plane and 250 m

Arisa [49]

Answer:

50 pmh

Step-by-step explanation:

Distance traveled by plane = 900 miles

Distance traveled by car = 250 miles

Let the speed of the car is c. The plane travels 250 mph faster than the car, so speed of the plane will be c + 250

Let the time taken to travel on car is t. She traveled 2 hours more on car the she rode on plane. This means she consumed 2 hours less time on plane. So the time spent on plane will be t - 2 hours.

Distance = Speed x Time

For Plane, the equation will be:

900 = (c + 250)(t - 2) Equation 1

Likewise, the equation for car will be:

250 = ct

From here, t = 250/c

Using this value in Equation 1, we get:

$900= (c + 250)(\frac{250}{c} -2)\\\\ 900=250 +\frac{62500}{c}-2c-500\\\\ 1150=\frac{62500}{c}-2c\\\\ 1150c=62500-2c^{2}\\\\ 2c^{2}+1150c-62500=0\\\\ \text{Using the quadratic formula, we get}\\\\ c=\frac{-1150\pm \sqrt{1150^{2}-4(2)(-62500)} }{2(2)}\\\\ c = -625, 50$

Since value of speed cannot be negative, we only consider the positive value. So from here we can conclude that the speed of the car was 50 mph

Aisha is playing a game in which she can gain or lose points on each turn. The table below

Varvara68 [4.7K]

Answer:

A score of -16 represents the lowest of points for these four turns.

The number for Aisha's highest score will be turn 2 on the number line.

That number is 10.

Step-by-step explanation:

Since the options of the drop down menu are not included, you should choose any option similar to lowest.

Aisha's highest score was obtained in turn 2 and that is 10.

Aisha is comparing absolute terms, that is why she believes that -16 represents a good score, while in reality is the worst she got.
