Answer:
Top Row:20,20
Bottom Row:26,26
Step-by-step explanation:
2(3m+7) when m is 1. Plug in to get: 2 (3*(1) + 7)=20
6m+14 when m is 1. Plug in to get: 6*(1) + 14=20
2(3m+7) when m is 2. Plug in to get: 2 (3*(2) + 7)=26
6m+14 when m is 2. Plug in to get: 6*(2) + 14=26
X + y = 5
xy = 12
x + y = 5
y = -x + 5
xy = 12
x(-x + 5) = 12
x(-x) + x(5) = 12
-x² + 5x = 12
- 12 - 12
-x² + 5x - 12 = 0
x² - 5x + 12 = 0
x = 5 ± √25 - 48
2
x = -5 ± √-23
2
x = -5 ± 4.79i
2
x = -5 + 4.79i or x = -5 - 4.79i
2 2
x = -2.5 + 2.395i or x = -2.5 - 2.395i
y = -2.5 - 2.395i or y = -2.5 + 2.395i
The two numbers that add up to 5 and multiply to 12 is -2.5 ± 2.395i, which is -2.5 + 2.395i and -2.5 - 2.395i.
Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x
Answer:
Step-by-step explanation:add by 13
12 + 13 = 25
25+ 13= 38
