Step-by-step explanation:
pass (0,2): y interception = 2
Line: y=mx+b b=2
Answer:
i) 75.8
ii) 997,002
Step-by-step explanation:
Each of these expressions can be rewritten to make evaluation a little easier.
<h3>i)</h3>
The difference of squares can be factored.
a^2 -b^2 = (a -b)(a +b)
8.79^2 -1.21^2 = (8.79 -1.21)(8.79 +1.21) = (7.58)(10) = 75.8

<h3>ii)</h3>
The values are near 1000, so can be expressed as differences from that number.
(999)(998) = (1000 -1)(1000 -2) = 1000^2 -3(1000) +2) = 997,002
This is a linear function. We are trying to find the output given an input of -5.
f(-5) = -3(-5)-4
f(-5) = 15-4
f(-5) = 11.
Solution: (-5, 11)
Given x=-5, input -5 in for x and follow PEMDAS to solve.
$87.5 i believe (sorry if it is wrong)
