What is the sum of the first 23 terms of the series 44+39+34+29+24

The series is A.P. with first term = 44 and common difference = 39-44=-5 = 34- 39

Sum of A.P. is S = n/2(2a+ (n-1)d)

Where a is first term ,d is common difference and n no. Of terms

Here a = 44 ,d= -5 and n = 23

S = 23 /2(2×44+ (23-1)(-5))

S=23/2(88-110)

S = 23/ 2(-22)

S = 23×-11

S = -253

an altitude of 15,000 feet

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
