Answer: True, False, False, False, False
<u>Step-by-step explanation:</u>
a) 5x - 7(x - 1)
5x - 7x + 7
-2x + 7 ⇒ a = -2, b = 7 <em>One Solution</em>
b) 3(x - 5) - 7
3x - 15 - 7
3x - 22 ⇒ a = 3, b = -22 <em>One Solution</em>
c) 2 - 7x + 3 + 4x
4x - 7x + 3 + 2
-3x + 5 ⇒ a = -3, b = 5 <em>One Solution</em>
d) -3(x - 3) - 1
-3x + 9 - 1
-3x + 8 ⇒ a = -3, b = 8 <em>One Solution</em>
e) -5x + 2 + 2x + 4
-5x + 2x + 2 + 4
-3x + 6 ⇒ a = -3, b = 6 <em>One Solution</em>
Step-by-step explanation:
55 > 4u + 15
40 > 4u
10 > u
so, this is true for all u < 10
Answer:
(2,1)
Explanation: f(x)=3x^(2)-12x+13
a=3
h=2
k=1
2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form
so

=

so your answer is
Answer:
54.872
Step-by-step explanation:
volume of a cube = s³
where s = side length
side length given here is 3.8
so volume = 3.8³ = 54.872
