A first number plus a second number is 10. Twice the first number plus the second totals 26.

Answers

1st number = x
2nd number = y

2x + y = 26
                    -
  x + y = 10

x = 16

26 - (2 x 16) = -6

10 - 16 = -6


Number 1 is 16
Number 2 is -6

For the functions f(x) = 2x − 6 and g(x) = 5x + 1, which composition produces the greatest output? A. Both compositions produce the same output B. Neither composition produces an output. C. f(g(x)) produces the greatest output. D. g(f(x)) produces the greatest output.

Answers

f(g(x)) = 2(5x+1)-6 = 10x+2-6 = 10x-4

g(f(x)) = 5(2x-6)+1 = 10x-30+1 = 10-29

10x-4>10-29 because from f(g(x)) you subtract less quantity.

James weight increased in 41 to 45 kilograms. what is the percentage increase?

Answers

The method of solving any question where you have to find the percentage increase is  to
First find the difference by subtracting the increase from the original which in this case is  45-41= 4
Then divide the difference by the original weight
4/41= 0.097
Lastly, multiply the answer to that by 100 to get your answer which is
0.097x 100 =9.7 %

so the answer is that the increase in weight is 9.7% 
9.7% would be the answer

an=a1+d(n-1)
a1=4
5th is 16
a5=4+d(5-1)=16
16=4+d(4)
minus 4
12=d(4)
divide 4
3=d

an=4+3(n-1)
an=4+3n-3
an=4-3+3n
an=1+3n

B is ansres
If the 5th term is stated, all you need to do is plug in 5 for the n value, as it represents the 5th term. The only equation that holds true for the 5th terms being 16 is B. 3n+1
1st term = 3(1)+1 = 4
2nd term = 3(2) +1 = 7
3rd term = 3(3) +1 = 10
4th term = 3(4) +1 = 13
5th term = 3(5)+1 = 16

Correct answer is B. 3n+1

Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2?A. y = –0.75x; 1.50
B. y = –1.33x; 2.67
C. y = 1.33x; –2.67
D. y = 0.13x; –0.25

Answers

Given:
y varies directly with x
y = 8 when x = -6

what is the value of y when x = -2?

y = kx

we need to get the constant of variation.
8 = k(-6)
8/-6 = k
4/-3 = k or - 1 1/3

y = -4/3 (-2)
y = (-4*-2) / 3
y = 8 / 3
y = 2 2/3 OR 2.67

The correct answer is Choice B. y = -1.33x ; 2.67
