Step-by-step explanation:

[tex]\dfrac{y^2+6y}{y^2-36}\qquad\qquad\qquad\qquad y\ne6\,,y\ne-6 \\\\ \\\dfrac{y^2+6y}{y^2-36}=\dfrac{y\cdot y+6\cdot y}{y^2-6^2}=\dfrac{y(y+6)}{(y+6)(y-6)}=\dfrac{y}{(y-6)}\\\\\\f(y)=y\\\\g(y)=y-6[/tex]

Answer:

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).

Answer:

  D.  The lines are perpendicular

Step-by-step explanation:

The first line has a rise of (1-2) = -1 for a run of (5-(-3)) = 8.

The second line has a rise of (-1-7) = -8 for a run of (1-2) = -1.

Then the slopes are -1/8 and -8/-1 = 8, which are negative reciprocals of each other. Lines with slopes having that relationship are perpendicular.

Answer:

The answer should be A

Step-by-step explanation:

Because 1/5k - 2/3j would be -2/3 j with 1/5 k missing which would mean it's the same as if you added it on instead of removing it

Answer:

QRS = 66° and Q = 95°

Step-by-step explanation:

Required Answer

[tex]\huge {\boxed{\sf{∠QSR=66⁰}}}[/tex]

[tex]\huge {\boxed{\sf{∠Q=95}}}[/tex]

Correct Question:

To find of :

Explanation:

∠QSR+∠QRT=180⁰

Reason:

linear pair

.°. ∠QSR+114⁰=180⁰

∠QSR=180⁰-114⁰

∠QSR=66⁰

Can also be done as follows:

To find value of ∠QSR first we have to find y

y⁰+(5y)⁰=114

Reason:

exterior opposite angle is equal to sum of interior angles

6y=114

y=114/6

y=19

y⁰+(5y)⁰+∠QSR=180⁰

Reason:

sum of angles of triangle =180⁰

6y+∠QSR=180⁰

6×19+∠QSR=180⁰

114+∠QSR=180⁰

∠QSR=180⁰-114⁰

∠QSR=66⁰

From second part we get the value of y

.°.∠Q=5×19

∠Q=95

Answer:

A & C

-4-7=-11 and -4+(-)=-11

-7-(-12) and -7+12

Step-by-step explanation:

-4-7= -11, -4+ (-7)= -11

-7-(-12) turns into -7+12=5

the second equation is the same as the first (after using PEDMAS), resulting in the answering being -7+12=5

The pairs of expressions that are equivalent will be -4 - 7 & -4 + (-7) and -7 - (-12) & -7 + 12. Then the correct options are A and C.

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Check all the options, then we have

A. -4 - 7 and -4 + (-7), then we have

-4 - 7 = - 4 + (-7)

B. 16 - 7 and -16 + 7, then we have

16 - 7 ≠ - 16 + 7

C. -7 - (-12) and -7 + 12, then we have

- 7 - (-12) = - 7 + 12

D. -2 - 3 and 2 + 3, then we have

- 2 - 3 ≠ 2 + 3

E. 10 - 2 and 10 - (-2), then we have

10 - 2 ≠ 10 - (-2)

The pairs of expressions that are equivalent will be -4 - 7 & -4 + (-7) and -7 - (-12) & -7 + 12. Then the correct options are A and C.

Answer:

Step-by-step explanation:

Step one:

given data

for the large cube

the volume= 125cm^3

we know that volume = l*l*l

volume=l^3

we want to find l, so we have to cube both sides

125=l^3

l=∛125

l=5cm

Step two:

given data

for the large cube

the volume= 27cm^3

we know that volume = l*l*l

volume=l^3

we want to find l, so we have to cube both sides

27=l^3

l=∛27

l=3cm

Answer:

f(x) – g(x) – h(x) = -5x^2 + 6x + 6

Step-by-step explanation:

Copy f(x) as is:            f(x) = 3x + 5

Negate g(x):              -g(x) = -4x^2 + 2

Negate h(x):               -h(x) = -x^2 + 3x - 1

Now combine like terms:

f(x) – g(x) – h(x) = -5x^2 + 6x + 6

Answer:

10cm correct to nearest cm" means the diameter could be arbitrarily close to (but less than) 10.5 cm. So the maximum possible circumference is 10.5π cm.

"10cm correct to nearest cm" also means that the diameter could be arbitrarily close to (but greater than) 9.5 cm. So the minimum possible area is π(9.5)²/4 cm²

Answer:

2M will be:

[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Therefore, the 2nd option is true.

Step-by-step explanation:

Given the matrix

[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]

Multiplying by 2 will basically be a scalar multiplication.

Therefore, multiply each of the matrix elements by a scalar.

[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]

       [tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]

        [tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Hence, 2M will be:

[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Therefore, the 2nd option is true.

Answer:

-1/10 for first one and -4/2 for second one

Step-by-step explanation:

lol can I have brainliest?

Hello!

Okay, so: To find the slope, you can use the slope formula: y2-y1/x2-x1...

Let's begin.

Start by plugging in given values into the formula. We can see from looking at the chart that,

y2 = -2

y1 = 3

x2 = 2

x1 = -8

Those are for set 1. So, Let's plug these values into the slope formula:

-2 - 3/2 - (-8)

Subtract

-5/10

Now divide

-1/2 or -0.5

Okay, now let's move on to Set 2.

Set 2:

We're going to do the exact same thing here that we did earlier. Given from the chart:

y2 = -3

y1 = -1

x2 = -2

x1 = 4

Plug them into the formula:

-3 - (-1) / -2 - 4

Subtract

-2 / -6

Divide

1/3

So, for set 1, the slope is -1/2. For set 2, the slope is 1/3.
