The slope of GA is -5. Find the slope of the line perpendicular to the given line
Temka [501]

Perpendicular slopes are opposite reciprocals.

This means the slope of the line perpendicular to GA will be the opposite reciprocal of -5.

Reciprocal of -5: -1/5

Opposite of -1/5: 1/5

The slope of the line perpendicular to GA is 1/5.

I have some answers the these problems but I just wanna make sure there right.. PLEASE Help??

7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21

10x-40=50
Add 40 to both sides
10x=90
X=9

4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20

Pls help me asap !!!!!
Phantasy [73]

Answer:

9

Step-by-step explanation:

This is a right triangle.  We can use the Pythagorean theorem to determine the missing side.

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a^2 + 12 ^2 = 15^2

a^2 +144 =225

a^2 = 225-144

a^2 = 81

Taking the square root of each side

a = 9

F(x)=2x^2-5x<br> G(x)=3x^3<br><br> Find f(x-2)<br><br> Please explain in depth
lesantik [10]

Answer:

Step-by-step explanation:

Whenever you're given something other than just 'x' as the input into the function, all you need to do is plug that expression into x in the original function and simplify

f(x) = 2x^2 - 5x

f(x-2) = 2(x-2)^2 - 5(x-2)\\f(x-2) = 2(x^2-4x+4) - 5x + 10\\f(x-2) = 2x^2 - 8x+8-5x+10\\f(x-2) = 2x^2-13x+18
