Answer: the correct options are B, D and F
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
m = slope = rate of change
Looking at the equations given, the three that apply are
B) slope = 7
y intercept = 4
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
D) y = 9x + 1
slope = 9
y intercept = 1
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
F) y = 8x + 5
slope = 8
y intercept = 5
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
The answer to the equation is approximately 536.91
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the point (0, 2). Therefore we have y-intercept 2 → b = 2.
The equation of the line is: w = mz + 2.
We have next point (1, 5). Substitute the coordinates of the point to the equation of the line:
<em>subtract 2 from both sides</em>
<h3>Answer: w = 3z + 2</h3>
Answer: B
y=(x+2)^2

Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
The function representing the spread of virus is:
Where x represents the number of hours after 1:00 pm
So, at 1:00 pm "x" will be equal to 0. So the domain will start from x = 0
According to the given statement, the virus spreads from 1:00 pm to 11:00 pm. So, the number of hours starting from 1:00 pm and ending on 11:00 pm will be the Domain. 11:00 pm means 10 hours after 1:00 pm i.e. x = 10
So, the domains starts at x = 0 and ends at x = 10. Therefore, the correct answer is 0 ≤ x ≤ 10
