Answer 1
Answers: -6 and -4
=======================================================
Explanation:
Refer to the drawing below. Locate 5 on the y axis. Draw a horizontal line extending as far as you can to the left and right.
This horizontal line crosses the parabola in two locations. From those two locations, drop a vertical line straight down until you reach the x axis. You should reach x = -4 and x = -6
This shows that f(-4) = 5 and f(-6) = 5.
Phrased another way: the points (-4,5) and (-6,5) are on the parabola.

Raj pays $7.99 per month for a movie subscription service. One month he also rents 3 movies from the service. His bill for the month is $19.96. How much does Raj pay to rent each movie?
Answers
raj pays $3.99 to rent each movie
explanation: you would subtract $7.99 from $19.96 and have a remainder of $11.97 and divide that by 3 to get $3.99
Answer:
Each movie costs 3.99
Step-by-step explanation:
If every month he is paying $7.99 initially for the service, you take $19.96 and subtract the initial cost ($7.99) then your left with $11.97 and since he bought 3 movies then you divide $11.97 by 3 and your left with $3.99 which is your final answer!
Hope this makes sense!

In the 1850s, the U.S government began encouraging Americans to head west to claim some of the country’s vas open areas. Pioneers were lured with the promise of owning their own land. But the trip could take months—if they survived it at all. Horse-drawn wagons were constantly at risk of breaking down in parched deserts, on barren plains, or in treacherous mountain passes. “Nothing but actual experience will give one an idea of the . . . exhaustive energy, the throbs of hope, the depths of despair, through which we lived,” on pioneer wrote.

1) g = -8 (one solution)
2) b = 0 (infinitely many solutions)
3) w = 5/6 (one solution)
4) c = 0 (infinitely many solutions)
Step-by-step explanation:
1) 1/2g -4 = 2g - 1/2g + 4
1/2g -2g +1/2 g = 8
-g = 8
2) 5.3-5.3 = 2.1b + b - 3.1b
0=0
3) 3/4w+ 3/4w = 10/4 - 5/4

Answer:
x = 6+3y
y = y (any number)
the rest should follow the same steps
Step-by-step explanation:
2x-6y=12 -> divide both sides by 2 (GCF)
x-3y = 6 -> solve for x, because it has 1 as its coefficient, or the lowest coefficent
x = 6+3y
-5x+15y=-30 -> divide both sides by 5
-1x+3y=-6 -> plug in x from previous equation
-(6+3y) + 3y = -6
-6-3y+3y = -6
y = y

answer attached: x = 5√2
Step-by-step explanation:
Answer:
Step-by-step explanation:
All of the right triangles are similar. This means ...
long side / short side = x/2 = 25/x
Multiplying by 2x gives ...
x² = 25·2
x = (√25)(√2)
x = 5√2
_____
Additional comment
The "geometric mean" of 'a' and 'b' is √(ab). With this in mind, you can see that x is the geometric mean of the lengths 2 and 25. This is always true for this right-triangle geometry.
There are two other geometric mean relations in this geometry, having to do with the other possible ratios of sides. In effect, the length of a segment that touches the hypotenuse (longest side) of the triangle is the geometric mean of the two segments of the hypotenuse it touches.
Left side = √(2·27) = 3√6
Bottom side = √(25·27) = 15√3
