Answer:
x < -16
Step-by-step explanation:
Any number less than -16 will work. So x could equal -12309 or -109 or -50 and even -19234870237503 would work.
To find which inequalities of x work, simply subtract 19 on both sides.

Step-by-step explanation:
Given

Solving (a): Number of lawns in $240

Multiply both sides by 20


Solving (b): Cost of mowing 9 lawns

Multiply both sides by 9


To create a graph, we need to generate a formula;
If




So:

Answer:
(x + 2)(x² - 2x + 4)
Step-by-step explanation:
x³ + 8 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
x³ + 8
= x³ + 2³
= (x + 2)(x² - 2x + 4)
ANSWER: 18
EXPLANATION:
y=kxzw
where k is a constant
Making k the subject of the formula, we have
k=y/xzw
Inputting the values
k= 72/(2)(1)(12)
k=72/24
k = 3
Solving for y when x=1,z=2 and w=3
We have
y=kxzw
y = (3)(1)(2)(3)
y = 18
