f(x) = 5x^2 - 4x

g(x) = 5x + 1

Therefore f - g = 5x^2 - 4x - (5x + 1)

= 5x^2 - 4x - 5x -1

= 5x^2 -9x - 1

Hope it helps :)

Answer:

Step-by-step explanation:

The n-th term of an arithmetic sequence: $a_n=a_1+d(n-1)$

so:

$a_5=a_1+d(5-1)\\a_5=a_1+4d\\a_1=a_5-4d\\a_1=44-4d\\\\a_{10}=a_1+d(10-1)\\ a_{10}=a_1+9d\\89=44-4d+9d\\45=5d\\d=9\\\\a_1=44-4\cdot9 = 8\\\\a_{21}=a_1+ 20d=8+20\cdot9=188$

What is the measure of angle A in the triangle?<br><br><br><br> Enter your answer in the box.

Rashid [163]

Angles in a triangle add up to 180 degrees.
(2x-10)+(x+30)+70=180
(2x-10)+(x+30)=110
3x+20=110
3x=90
x=30
so A:
2(30)-10
=50
