What is equivalent to 7(3x-2)+4(x+5)
Sladkaya [172]

Distribute 7 to 3x and -2, and 4 to x and 5

7(3x - 2) = 21x - 14

4(x + 5) = 4x + 20

Combine like terms

21x + 4x = 25x

-14 + 20 = 6

25x + 6 is your answer

hope this helps

Compare the values 4x107 is what times as much as 4x103
dezoksy [38]

Answer:

10^{4}

Step-by-step explanation:

4 x 10^7 is 40000000

4 x 10^3 is 4000

We are told that 4x10^7 is something times as much as 4x10^3

So we will work backwards to find the answer,

If you divide 40000000 by 4000 you will get 10000

10000 is the same as 10^4

I need answers for 1 and 2
Snowcat [4.5K]

1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5
