Please, see the offered decision:
1) common equation for lines is y=kx+b. If k₁=k₂ (for line 1 and line 2) ⇒ 'line 1' || 'line 2'.
2) for line 3x+5y=6 k= -3/5. It means (according to item 1) for unknown line k is the same (-3/5).
3) using points (0;3) it is easy to find parameter b (x=0, y=3) via y=kx+b:
3=0*(-3/5)+b ⇔ b=3.
4) finaly (k=-3/5; b=3):
Answer:Complementary angles are two angles whose degree measurements add up to 90 degrees. The first angle would be (x + 14.4) and its complementary angle would be x. Therefore, you would set up this problem as: x + (x + 14.4) = 902x + 14.4 = 902x = 75.6 x = 37.8 (one angle)And (x + 14.4) = 52.2 (other angle).
To check: 37.8 + 52.2 = 90

9:7 There are 18 girls to 14 boys. 18/14 divide top and bottom by 2 to simplify equals 9:7
Answer: B. There are no integers that are whole numbers.
<u>Step-by-step explanation:</u>
A. Whole numbers are never irrational. TRUE
B. There are no integers that are whole numbers. FALSE!
There ARE integers that are whole numbers because Integers are positive and negative whole numbers.
C. There is only one whole number that is not a natural number. TRUE
Whole Numbers: 0, 1, 2, 3, ...
Natural Numbers: 1, 2, 3, ...
D. Natural numbers cannot be negative. TRUE
