Answer:
<h3>
Any of them.</h3><h2>
a ∈ R</h2>
Step-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.
Answer:
D
Step-by-step explanation:
rule: Diametre includes the centre of a circle.
According to the given conditions AB and DE are diameters.
X= 7 1/3
Explanation- Take 72 and subtract 50 from that giving you 22. Then take 22 and divide it by 3 to get 7.3333333333333 (repeats) or 7 1/3
Answer:
C
Step-by-step explanation:
given
x + 19 ≤ - 5 ( isolate x by subtracting 19 from both sides )
x ≤ - 24 → C
