-3x+7

Step-by-step explanation:

The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.

f -1(x)= -1(3x-7)

f -1(x)= -3x+7

Which ordered pair is generated from the equation shown below? y = 3x + 2 A. (3, 11) B. (3, 9) C. (5, 15) D. (2, 4)

Answer:

y = 3x + 2

There slope is 3 and intercept is 2.

First find what are the 2 pair that given by slope =3

First consider A. (3, 11) and B. (3, 9)

Tan α = \fraction(11-9)(3-3)

It is undefine.

Next consider A. (3, 11) and BC (5,15)

Tan α = \fraction(15-11)(5-3)

Next consider A. (3, 11) and D. (2,4)

Tan α = \fraction(11-4)(3-2)

Next consider B (3, 9) and C. (5,15)

Tan α = \fraction(15-9)(5-3)

So this is ordered pair is generated from slope =3

Pythagoras anyone???

exis [7]

8^2 + 5^2 = 64+25 = 89 = square root 89
I don't have a calculator on me lol.

that specific side opposite the right angle is always the longest angle
a^2+b^2=c^2

Write an exponential function in the form y = ab that goes through points (0,19) and (5,4617).

Answer:

y = 1/2 (2)x

Step-by-step explanation:

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2
