Let f(x)= x^2 -2x+6 find f(-1)
Leokris [45]

Answer:

Step-by-step explanation:

f(x) = x^2 - 2x + 6

to find f(-1), we sub in -1 for every x

f(-1) = (-1^2) - 2(-1) + 6

f(-1) = 1 + 2 + 6

f(-1) = 9 <=======

Rewrite this expression as an integer: 4^-3 4^5
Zina [86]
4^-3 would be 1/64 since you flip the 4 over when you have a negative power and 4^5 would be 1024 (4 x 4 x 4 x 4 x 4) so your final answer would be 16 
because you have to divide 1024 by 64

Find the measure of each marked angle.
Tatiana [17]

Answer:

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Step-by-step explanation:

In a triangle, the sum of all inside angles must be 180 degrees.

In this question:

The inside angles are: x, x + 50 and 180 - 3x.

Then

x + x + 50 + 180 - 3x = 180

2x - 3x = -50

x = 50

So

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
