Answer:
×=14
Step-by-step explanation:
2(3×+5)=7×-4
6×+10=7×-4
7×-6×=10-(-4)
×=14
I believe you have 6 bacteria 120 divided by 20 is 6 so
Answer:
D) y = − 3/2 x + 3 /2
Step-by-step explanation:
3x+2y =1
We need to get this in slope intercept form (solve for y)
Subtract 3x from each side
3x-3x +2y = -3x+1
2y = -3x+1
Divide by 2
2y/2 = -3/2x+1/2
The slope is -3/2
We want a line that is parallel so the slope is the same
m = -3/2
We an use point slope form since we have the slope and a point
y - y1 = m(x-x2)
y - 0 = -3/2(x-1)
Distribute
y = -3/2x +3/2
