Answer:
y = -1/2 x - 3 1/2
Step-by-step explanation:
points (1, -4) (3,-5)
slope = (y2-y1)/ (x2-x1)
slope = (-5--4)/(3-1)
= (-5+4) /2
=-1/2
point slope form of a line
y-y1 = m(x-x1)
y--4 = -1/2 (x-1)
y+4 = -1/2 (x-1)
if we want slope intercept form
distribute
y+4 = -1/2 x + 1/2
subtract 4 from each side
y+4-4 = -1/2 x + 1/2 -4
y = -1/2 x - 3 1/2
The answer is 30
2 * 15 = 30
5 * 6 = 30
30 is between 24 and 34
Answer:
y=-10
Step-by-step explanation:
y=-2(3)-4
y=-10
Answer:
B
Step-by-step explanation:
The wording in the problem statement is ...
... "less than 3 years"
... "at least 3. but less than 6 years"
so we expect the inequality symbols to look like ...
... 0 ≤ x < 3
... 3 ≤ x < 6
These match <em>the second piecewise function</em>.
Slope 2/1, y intercept is 6, equation is f(x)=6-2x
