Answer:
A
Step-by-step explanation:
The slope is positive, the y intercept is -1/2, and and it's going 8 left and 5 up therefore 8/5
The answer is -220
What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this.
-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22
Simplify that to -7 x 66 +11 x 22
now multiply -7 and 66 to get -462
-462 +11 x 22
multiply 11 and 22
-462 + 242
and your final answer will be -220
Answer:
12 square units
Step-by-step explanation:
A = 1/2·h(sum of bases)
A = 1/2(4)(2+4)
A = 2(6) which is 12 square units
Since f(x) = 2x - 1, all you need is to replace x with (a+h)
So f(a+h) = 2(a+h) - 1 = 2a + 2h - 1
