Write the formula for absolute value function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).

Answer:

the solution is (5, 6)

Step-by-step explanation:

Please reserve " × " for representing multiplication, and " x " as a variable name.

Starting with the system

6x-5y= 0  

4×-5y = -10​

multiply the 2nd equation by -1.  This results in the system

6x - 5y  = 0  

-4x + 5y = 10

and combining these two equations results in

​ 6x - 5y  = 0  

-4x + 5y = 10

------------------

2x         = 10, or x = 5.

Substituting 5 for x in the first equation, we get

6(5) - 5y = 0, or 5y = 30.  Then y = 6, and the solution is (5, 6).

Answer:

C.

Step-by-step explanation:

(m^2-m-3) + (m-4)

there is no like terms for m^2 so it stays the stay.

next you add -m to m because the first m is negative they cancel out leaving nothing. lastly we add -4+-3 these added together give you -7.

so you are left with m^2 +0 -7

which simplifies to m^2 - 7

The radius of the circle with a circumference of 12.56 inches is 2 inches, calculated using the formula C = 2πr and rearranging it to find the radius.

The circumference of a circle is given by the formula C = 2πr, where C stands for the circumference and r stands for the radius of the circle. The value of π (pi) is approximately 3.14159. Given the circumference of the circle as 12.56 inches, you can find the radius by rearranging the equation to r = C / (2π).

Now, let's calculate the radius using the given circumference:

r = 12.56 inches / (2 × 3.14159)

r = 12.56 inches / 6.28318

r = 2 inches

Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.

To find the measure of the radius of the circle given its circumference, we can use the circumference formula of a circle, which is:
\[ C = 2 \pi r \]
Where \( C \) is the circumference, \( \pi \approx 3.14159 \), and \( r \) is the radius of the circle.
Now, we know the circumference (\( C \)) is 12.56 inches. We can solve for the radius (\( r \)) by rearranging the formula:
\[ r = \frac{C}{2 \pi} \]
Plugging the given circumference into the equation, we get:
\[ r = \frac{12.56}{2 \times \pi} \]
\[ r = \frac{12.56}{2 \times 3.14159} \]
\[ r = \frac{12.56}{6.28318} \]
\[ r = 2 \]
Rounding the result to two decimal places as may be required for some comparisons, we still get \( r = 2.00 \) inches.
Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.

ANSWER

y=(x+3)(x-1)(x-5)

EXPLANATION

The given polynomial has x-intercepts at x=-3,x=1,x=5

These are called the zeros of this polynomial.

We can use the factor theorem to obtain the polynomial in factored form.

The polynomial in factored form is of the form

y=a(x+3)(x-1)(x-5)

The polynomial rises on the left and keep rising on the right.

This implies that, the 'a' is positive.

Therefore

y=(x+3)(x-1)(x-5)

The correct choice is the first option.

Answer: y = (x + 3)(x - 1)(x - 5)

So in your case, it would be C.

The function in which above two property hold true is:

         B.   [tex]F(x)=\dfrac{x}{(x-1)(x+1)}[/tex]

( since in option: A

If denominator equal to 0 then x=0 and -1

This means that the vertical asymptotes are 0 and -1 .

In option: C

If denominator is equal to zero.

Then x=0 and 1

This means that the vertical asymptotes are 0 and 1

In option: D

When denominator=0

then x=0

This means that the vertical asymptote is at x=0

which is false )

* In ΔABC

- a, b, c are the lengths of its 3 sides, where

# a is opposite to angle A  ⇒ BC

# b is opposite to angle B  ⇒ AC

# c is opposite to angle C  ⇒ AB

- m∠C = 68°  

- a = 8 ⇒ side BC

- b = 11 ⇒ side AC

- Find the value of c ⇒ side AB

* We have the length of two sides and the measure of the

  including angle between them and we want to find the

  length of the side opposite to this angle then the cosine

  rule is the perfect way

∵ c² = a² + b² - 2ab cos(C)

∵ a = 8 , b = 11 and m∠C = 68°

∴ c² = (8)² + (11)² -2(8)(11) cos(68°)

∴ c² = 119.069 ⇒ take √ for both sides

∴ c = 10.9 units

* The value of c is 10.9

Answer:

Step-by-step explanation:

Points to remember

solution of a quadratic equation ax² + bx + c = 0

x = [-b ± √(b² - 4ac)]/2a

It is given that, x² + 9x + 10 = 0.

To find the solution

Here a = 1, b= 9 and c = 10

x = [-b ± √(b² - 4ac)]/2a

 = [-9 ± √(9² - 4*1*10)]/2*1

 = [-9 ± √(81 - 40)]/2

 =  [-9 ± √(41)]/2

 = [-9 ± √41]/2

Therefore the solution of given quadratic equation  =  [-9 ± √41]/2

To solve the equation (x - 3)(x + 9) = -27, we simplified and set the quadratic equation to zero, which leads to solutions x = 0 or x = -6. We need to cross-verify this with the original equation as the student suggested different solutions.

To find a solution to the equation (x - 3)(x + 9) = -27, we can start by simplifying the left side of the equation. We'll distribute the terms:

x² + 9x - 3x - 27 = -27

Then we combine like terms:

x² + 6x - 27 = -27

To make it easier to solve, we want to set the equation to zero:

x² + 6x - 27 + 27 = 0

x² + 6x = 0

We factor out an x:

x(x + 6) = 0

Now, we can use the zero product property, which states that if a product of two factors is zero, then at least one of the factors must be zero:

x = 0 or x + 6 = 0

Which gives us the solutions:

x = 0 or x = -6

But the student has mentioned that the solutions are x = 3 or x = -7. To double-check, we substitute these values back into the original equation:

(3 - 3)(3 + 9) and (-7 - 3)(-7 + 9)

Both expressions simplify to an identity. Thus, there may be a mistake in our initial simplification, and we should review it to ensure accuracy.

Answer:

1:3

Step-by-step explanation:

if a + b = 4a then b has to be 3a

(1) + (3) = 4(1)

(2) + (6) = 4(2)

it works no matter what you plug in for a

To find the ratio a:b given that a+b=4a, we rearrange the equation to find b=3a, and then simplify the ratio to get 1:3.

To find the ratio a:b, given that a+b=4a, we first need to express b in terms of a. This can be done by subtracting a from both sides of the equation:

a + b - a = 4a - a

b = 3a

Now that we have b expressed as 3a, we can find the ratio of a to b:

a : b = a : 3a

As we can simplify the ratio by dividing both terms by a (assuming a is not zero):

a : b = 1 : 3

Therefore, the ratio of a to b is 1:3.

Answer:

A. he held the tube iver the flame too long

Final answer:

The cracking of the test tube could have been caused by thermal shock due to overheating one side of the test tube by holding it over the flame for too long, or by heating an empty test tube meant for containing liquids.

Explanation:

When heating substances in a test tube, such as in a chemistry lab, it's important to take certain precautions to prevent accidents, such as the cracking of the test tube. One potential cause for a test tube to crack is thermal shock, which can occur if the test tube is heated too quickly or unevenly. This brings us to option A: 'He held the test tube directly over the flame for too long'. Holding a test tube directly in the flame can cause one side to expand more rapidly than the other due to the heat, leading to stress and cracking, particularly if the glass isn't designed to withstand rapid temperature changes. To avoid this, the test tube should be moved in and out of the flame to heat it gently and evenly, and a boiling chip can be used to prevent superheating and ensure smooth boiling.

Option B suggests another possibility: 'He did not add water to the test tube'. While not adding water to a test tube might not directly cause it to crack, if the test tube was meant to contain a liquid and was instead heated while empty, the glass could become too hot and weaken, increasing the chance of breaking. It's always important to follow specific instructions for each experiment, including whether or not to add substances to the test tube.

Both scenarios emphasize the importance of careful temperature control when heating glassware to avoid breakage from thermal stress.

Answer:

Can you provide a picture/

Step-by-step explanation:

Answer:

(-15)/3 = -5  

Step-by-step explanation:

(-15)/3

Assume that your positive tiles are yellow, and your negative tiles are red.

The question is asking, "if you take 15 red tiles and split them into three equal groups, how many will you have in each group?"

How can you model the first value of -15?  With 15 red tiles.

Let’s model how to divide the tiles into three equal groups by moving one tile at a time into three separate groups until all 15 tiles have been moved.

Step 1.

Start with 15 red tiles, as in the first picture.

Step 2.

Start by moving tiles one at a time to begin creating three new groups.

The middle picture shows the situation after you have moved the first three tiles.

Step 3.  

Continue moving tiles one at a time from the original group and stacking them evenly in the three new groups until you have no more tiles to move.  

The third picture shows the situation when you have finished.

How many red tiles are in each group?  There are five.

Is the answer positive or negative?  The answer is negative, because there are five red negative tiles in each group.

Conclusion? (-15)/3 = -5

Integers are expressions without decimals.

The result of the quotient of -15 and 3 is: -5

The expression is given as:

[tex]\mathbf{\frac{-15}{3}}[/tex]

To do this using integer tiles, we start by isolating the negative sign

[tex]\mathbf{\frac{-15}{3} = (-)\frac{15}{3}}[/tex]

Then divide 15 by 3 (see attachment for illustration of the division)

From the attached figure, we have:

[tex]\mathbf{\frac{15}{3} = 5}[/tex]

Substitute 5 for 15/3 in [tex]\mathbf{\frac{-15}{3} = (-)\frac{15}{3}}[/tex]

So, we have:

[tex]\mathbf{\frac{-15}{3} = (-)5}[/tex]
