1. 3rd one
2. f(x) = 7x - 5
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
3. c(n) = 0.75n - 0.25
4. (0,0)(2,4)
slope = (4 - 0) / (2 - 0) = 4/2 = 2
answer is : y = 2x
Answer:
A
Step-by-step explanation:
This is a linear function whose slope is -3 and whose y-intercept is (0, 2). Answer A is correct.
Answer:

Step-by-step explanation:
<h2>Equation of the line in slope intercept form:</h2>

Here m is the slope or gradient and b is the y-intercept.
Write the given equation in slope-intercept form.
2x + 3y = 6
3y = -2x + 6


Answer: 12 cm
Step-by-step explanation:
The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3
The greater radius is 3*4=12 (cm)
