Answer:
The equation of the line that passes through (1, 2) is y = - 2x + 4
Step-by-step explanation:
2x + y - 1 = 0
2x + y - 1 + 1 = 0 + 1
2x + y = 1
2x - 2x + y = 1
y = - 2x + 1
parallel lines have the same slope, so the equation line will be -2
plug in the point, y = mx + b (x, y)
y = (-2)x + b , (1, 2)
(2) = (-2)(1) + b
2 = -2 + b
2 + 2 = -2 + 2 + b
4 = b
y = - 2x + 4
Answer:
<em>She needs to add no fertilizer, option A)</em>
Step-by-step explanation:
<u>Equation of a Line:</u>
According to the conditions of the question, being x the ounces of fertilizer Olivia adds to the soil, and y the number of blooms each rose bush has, the relation between them is

It's bee required to compute the value of x such that the roses have 4 blooms, thus

Solving for x


This means she needs to add no fertilizer, option A)
I'm gonna need some sort of diagram...
Answer:
Technically it is 5/12, but as a percentage it would be 41.6666%
2(25)^x would be the correct equivalent function
