Step-by-step explanation:
y2−x2+1=50
Step 1: Add -y^2 to both sides.
−x2+y2+1+−y2=50+−y2
−x2+1=−y2+50
Step 2: Add -1 to both sides.
−x2+1+−1=−y2+50+−1
−x2=−y2+49
Step 3: Divide both sides by -1.
−x2
−1
=
−y2+49
−1
x2=y2−49
Step 4: Take square root.
x=√y2−49 or x=−√y2−49
Answer:
x=√y2−49 or x=−√y2−49
y2+6y+9=x+8
Step 1: Flip the equation.
x+8=y2+6y+9
Step 2: Add -8 to both sides.
x+8+−8=y2+6y+9+−8
x=y2+6y+1
Answer:
x=y2+6y+1

Which inequality below satisfies the solution set graphed on the following number line?
Answer:
D.
Step-by-step explanation:
The function must have the range -3 to 5.
2x^2 - 4x - 30
= 2(x^2 - 2x - 15)
= 2(x + 3)(x - 5)
so the critical points are -3 and 5.
When x = -2 f(x) = 2* 1 * -7 = -14 <= 0
when x = 4 f(x) = 2 * 7 * -1 <= 0.
when x= 0 f(x) < 0
So its the last option.

Pipe A can fill a tank in 5 hours. Pipe B can fill the same tank in 7 hours. If both pipes were open, how long would it take them to fill an empty tank?
Answer:
It would take them 6 hours to fill an empty tank.
Step-by-step explanation:
Add the amount of time it takes Pipe A and Pipe B to fill an empty tank together (5 + 7) and then divide your sum by two. You should get 12 / 2 = 6.

3x+3<36
pls help i’m not sure what it is
Answer:
Step-by-step explanation:
get the x alone by subtracting 3 from each side.
3x+3-3<36-3
3x<33
divide by three
3x/3<33/3
x<11
Hello There!
Solving inequalities is almost like solving equations.
x<11.
Let me explain step-by-step.
3x<36-3
3x<33
x<11
We must isolate x.
x < 11 means x is less than 11.
It could be 10, -100, as long as it is less than 11, it would make the inequality true.
Let's verify.
3(10)+3<36
30+3<36
33<36
It's true, isn't it?
Hope it helps! :)

ranges are,
-1 , -11 and 7
hope this answer helps you dear!
Answer:
R = { - 11, - 1, 7 }
Step-by-step explanation:
Substitute the values from the domain into f(x) for range
f(2) = - 2(2)² + 7 = - 2(4) + 7 = - 8 + 7 = - 1
f(- 3) = - 2(- 3)² + 7 = - 2(9) + 7 = - 18 + 7 = - 11
f(0) = - 2(0)² + 7 = - 2(0) + 7 = 0 + 7 = 7
Then
R = { - 11, - 1, 7 }

Divide.
(−14)÷(−34)
What is the quotient?
Enter your answer as a simplified fraction in the box.
Answer:
[tex] \frac{7}{17} [/tex]
Step-by-step explanation:
(-14) ÷ (-34)
14/34
= ⁷/17
The quotient of the division will be 0.41. And the solution of the division (−14) by (−34) would be 7/17 as a simplified fraction.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
We need to divide the mixed fraction with integers, So
(-14) ÷ (-34)
The common denominator we can calculate as the least common multiple of the denominators then we get
14/34
= 7/ 17
= 0.41
Thus, the quotient of the division will be 0.41
Therefore, the solution of the division (−14) by (−34) would be 7/ 17 as a simplified fraction.

There are 115 flowers on 7 trees. What is the unit rate of the flowers per tree? How many flowers on 22 trees?
Answer: 16 flowers per tree, 352 flowers on 22 trees.
Step-by-step explanation:
115 flowers/ 7 trees= 16.4 flowers per tree
Since you can't have partial flowers, round down to 16 flowers per tree.
16 flowers per tree * 22 trees=352 flowers

Over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day what was the total change in the water level
A:10.55
B:-8.16
C:8.16
D:-10.55
If over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be: C:8.16
Centimeter each day=-0.32
Days of changed in water level=25.5 days
Now let determine total change in the water level
Total change=25.5 days × (-0.32)
Total change=8.16 centimeter
Inconclusion if over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be: C:8.16
