Answer:

Step-by-step explanation:

y= mx+ b helps you find the equations of the lines

y= x+2 is the line with slope m=1, and y-intercept b=2

y= -4x-3 is the line with slope m=-4, and y-intercept b=-3

y > x+2 because is a dotted line

y ≤ -4x-3 because is a solid line

Given: f(x)=1/x+5 and g(x)=x-2
pogonyaev

Answer:

x cannot be -3 or 2

Step-by-step explanation:

f(g(x)) = 1 / (( x-2) +5)

         = 1/ (x+3)

g(x) cannot have x=2

The domain is restricted where

f(x) has an restriction that x cannot be 5

so g(x) cannot be -5

-5 = x-2

Add 2 to each side

-5+2 = x

-3

1a) Use the pythagorean theorem tofind the missing side length.
Lana71 [14]

Answer:

1)

a)

We are given one leg of triangle as 6 km and the other leg is of length of 8 km.

Hence, the hypotenuse is calculated using Pythagorean theorem as:

x^2=8^2+6^2\\\\\\x^2=64+36\\\\x^2=100\\\\x=10

Hence, the hypotenuse of the triangle or the missing side x=10 cm.

Now we calculate trignometric  ratio with respect to angle a and b as:

b)

We know that:

Sine of an angle is ratio of perpendicular to hypotenuse.

Cosine of an angle is ratio of base and hypotenuse.

And tangent of an angle is ratio of perpendicular and base.

<u>Angle a:</u>

We have perpendicular=8

Base=6

Hypotenuse=10

Hence,

sin a=8/10

cos a=6/10

tan a=8/6

<u>Angle b:</u>

Perpendicular =6

Base=8

Hypotenuse=10

Hence,

sin b=6/10

cos b=8/10

tan b=6/8

Evaluate 1/x^-2 for x= 7.<br> -49<br> 49<br> 1/49<br> Please help <br> And thx but HURRY
ella [17]
Answer: 49

Step-by-Step Explanation:

As we can see, we have been given a negative exponent for “x”. Hence we have to take the reciprocal which would be x squared.


Therefore, x = 7
= x^2 = 7 * 7
= 49
