Answer:

(-6,1)

Step-by-step explanation:

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

(-6,1) Remember that the x-axis is the horizontal axis on a coordinate plane and the y-axis is the vertical axis in a coordinate plane. :)

Solve the following quadratic equation for all values of x in simplest form. 7+2x^2=11

ollegr [7]

Answer:

$x=-\sqrt2\text{ or } x=\sqrt2$

Step-by-step explanation:

We have:

$7+2x^2=11$

To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:

$2x^2=4\\$

Divide both sides by 2:

$x^2=2$

Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:

$x=\pm\sqrt2$

Therefore, our solutions are:

$x=-\sqrt2\text{ or } x=\sqrt2$

which of the following numbers which of the following numbers when added to it perfect squares is 240

Katena32 [7]

Answer:

first of all square mean two number or double so if we multiple 15×15=225 and if we multiply 16×16=256 mean the number 240 lies between them what about number 15.5 lets try now 15.5×15.5=240.25 if you want to make sure so just take a square root of this number

$\sqrt{240.25} = 15.5$

so 240 is product of (15.5)² note number after point is negligible

One positive number is 5 times another number . The difference between the two numbers is 80, Find the numbers.

nika2105 [10]

---------------------------------------------------------------------------------------------------
Define the numbers:
---------------------------------------------------------------------------------------------------
Let x be one number.
One number = x
Other number = 5x

---------------------------------------------------------------------------------------------------
Construct the equation:
---------------------------------------------------------------------------------------------------
5x - x = 80

---------------------------------------------------------------------------------------------------
Combine like terms:
---------------------------------------------------------------------------------------------------
4x = 80

---------------------------------------------------------------------------------------------------
Divide by 4 on both sides:
---------------------------------------------------------------------------------------------------
x = 20

---------------------------------------------------------------------------------------------------
Find the 2 numbers:
---------------------------------------------------------------------------------------------------
One number = x = 20
Other number = 5x = 5(20) = 100

---------------------------------------------------------------------------------------------------
Answer: The two numbers in increasing order are 20 and 100.

Walt is mixing fruit punch for a party. He combines 1 gallon 2 quarts 3 pints of orange juice, 1 gallon 3 quarts 7 pints of pine

Naya [18.7K]

The answer is C. 6 gal. 2 qt. 1pt
there are already three gallons so
1 gal + 1 gal + 1 gal = 3 gal
1 gal = 4q
2 q + 3q + 3q = 8q = 2 gal
1 gal = 8p
3p + 7p + 3p = 13p - 8p = 5p
2p = 1q
5p - 4p = 1p
Hope it helps
