Answer:
<u>Step-by-step explanation:</u>
Left line:
slope (m) = 1 and y - intercept (b) = 3
equation in slope-intercept (y = mx + b) format is: y = x + 3
this line exists only when x ≤ 2
Right line:
a point on the line = (2, 5) and slope (m) = -1
equation in point-slope [y - y₁ = m(x - x₁)] format is: y - 5 = -(x - 2)
convert that to slope-intercept format: y = -x + 2 + 5 ⇒ y = -x + 7
this line only exists when x ≥ 2
Step-by-step explanation:
14.2a + 9.8b -13.1b + 0.2a - 3.7a -4.8b
= 14.2a + 0.2a -3.7a + 9.8b -13.1b -4.8b
= .......a + or - ....... b
Answer:
f(3) = 113
Step-by-step explanation:
Using the recursive rule and f(1) = 8 , then
f(2) = - 4f(1) + 5 = - 4(8) + 5 = - 32 + 5 = - 27
f(3) = - 4f(2) + 5 = - 4(- 27) + 5 = 108 + 5 = 113
Answer: -118
Step-by-step explanation:
first multiply by 40. 37x 40 is 1480. No subtract 64 from both sides (1416). Multiply both sides by negative one to make the parentheses positive. -(1416)
on the inside that would be 12y so divide -1416 by 12 which is -118
I hope that's right!! :)
NOTE it isn't -118 sorry!!! I didn't see that in the original post
