Find the inverse of the function y = x2 – 12.

Answer:

2x-6y=-24

2x=-24+6y

x=-24+6y÷2

x=-12+3y equation 1

x+(-5y)=-22

-12+3y-5y=-22

-13-2y=-22

-2y=-22+13

-2y=-9

y=-9÷2

y=4.5equation 2

putting value of equation 2 in equation 1

x=-12+3y

x=-12+3×4.5

x=-12+13.5

x=1.5 answer!!!

Answer: You would have to send 300 text messages

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30

3. Divide both sides by 0.10 to get x = 300

Answer:

7m + 5

Step-by-step explanation:

1) Simplify.

(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4

2) Eliminate unnecessary parenthesis.

(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.

3) Combine like terms.

12m - 5m = 7m, 4 + 1 =5 -> 7m + 5

The solution is 7m + 5

Answer:

As the slope is -2, so the rate of change of the function is:

Step-by-step explanation:

The slope is basically the rate of change of a function.

Let us take the two points from the graph

Taking the slope between two points to determine the rate of change of a function

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]

[tex]m=-2[/tex]

As the slope is -2, so the rate of change of the function is:

Answer:

C(-2,-5).

Step-by-step explanation:

FOR A CLOCKWISE 270° ROTATION:

Given point A(x,y) its image is given

as A`(y,-x).

For the image of C which is C`(-5,2)

Comparing this to A`(y,-x)

y = -5 and -x = 2,x = -2

hence C compared to A(x,y)

will be C(-2,-5).

Answer:

C. y = -1/2 + 2

Step-by-step explanation:

First, we need to find the Slope.

Points: ( -4,4) and (8,-2)

Formula: m = y2 - y1/x2 - x1

m = y2 - y1/x2 - x1

m = -2 - 4/8 - (-4)

m = -6/8 + 4

m = -6/12

m = -1/2

Alright, now that we have the Slope, we can now use the Slope Form to find the Slope Intercept Form.

Point: (8,-2) (You may choose any points, but I would like to choose these for no reason)

Slope: -1/2

Formula: y - y1 = m(x - x1)

y - y1 = m(x - x1)

y - (-2) = -1/2(x - (8))

y + 2 = -1/2x + 4

y = -1/2 + 4 - 2

y = -1/2 + 2

The Slope Intercept Form is: y = -1/2 + 2

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{2 \sqrt{26}}} \: \: \text{units} } } [/tex]

Let the points be A and B. Now,

Use the distance formula to determine the distance between A ( 5 , -6 ) and B ( 3 , 4 ).

[tex] \boxed{ \underline{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}}[/tex]

Substitute the actual value of the points into the distance formula and then simplify.

[tex] \dashrightarrow{ \sf{ \sqrt{ {(3 - 5)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]

Remember : The positive and negative integer are always subtracted but posses the sign of the bigger integer.

[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]

Remember : ( - ) × ( - ) = ( + )

[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 + 6)}^{2} } }}[/tex]

Add the numbers : 4 and 6

[tex] \longrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(10)}^{2} } }}[/tex]

Evaluate the power

[tex] \longrightarrow{ \sf{ \sqrt{4 + 100}}} [/tex]

Add the numbers : 4 and 100

[tex] \dashrightarrow{ \sf{ \sqrt{104}}} [/tex]

[tex] \dashrightarrow{ \boxed{ \sf{2 \sqrt{26} }}}[/tex] units

Therefore , The distance between ( 5 , -6 ) and ( 3 , 4 ) is [tex] \sf{2 \sqrt{26}} [/tex] units .

And we're done!

Hope I helped!

Have a wonderful time ! シ

Answer:

sine(pie/5+pie/2)

Step-by-step explanation:

The expression, written as the sine of an angle is sin (7π/10)

Trigonometry Identities

From the question, we are to write the given expression as the sine or cosine of an angle.

The given expression is

sin(π/5)cos(π/2) + sin(π/2)cos(π/5)

Let A = π/5

and

B = π/2

Thus, we get

sinA cosB + sinB cosA

From the given information, we have that

sin(A ± B) = sinA cos B ± cosA sinB

∴ sin(A + B) = sinA cos B + cosA sinB

Now,

sinA cosB + sinB cosA = sinA cosB + cosA sin B

∴ sinA cosB + sinB cosA = sin (A + B)

Put A = π/5

and

B = π/2

sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (π/5 + π/2)

sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (7π/10)

Hence, the expression, written as the sine of an angle is sin (7π/10)

Step-by-step explanation:

Answer:

y + 5 = 2(x - 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (5, - 5) , thus

y - (- 5) = 2(x - 5) , that is

y + 5 = 2(x - 5)
