Answer:
y >
Step-by-step explanation:
Given
5y + 3 > - 7y + 13 ( add 7y to both sides )
12y + 3 > 13 ( subtract 3 from both sides )
12y > 10 ( divide both sides by 12 )
y > , that is
y >
When discriminant >0, then it contrains 2 distinct real zeros.
Discriminant=6 and 6>0 so, you have 2 solutions.
8 3/5 is between 8 and 9
so point D would be correct
x=0 .
−2(8+8x)+7x=−7x+2(x−8)
Step 1: Simplify both sides of the equation.
−2(8+8x)+7x=−7x+2(x−8)
(−2)(8)+(−2)(8x)+7x=−7x+(2)(x)+(2)(−8)(Distribute)
−16+−16x+7x=−7x+2x+−16
(−16x+7x)+(−16)=(−7x+2x)+(−16)(Combine Like Terms)
−9x+−16=−5x+−16
−9x−16=−5x−16
Step 2: Add 5x to both sides.
−9x−16+5x=−5x−16+5x
−4x−16=−16
Step 3: Add 16 to both sides.
−4x−16+16=−16+16
−4x=0
Step 4: Divide both sides by -4.
−4x

Answer:
⟨3, –5⟩ and ⟨6, –10⟩
Step-by-step explanation:
⟨3, –5⟩ cross ⟨6, –10⟩ = 0
⟨2, –3⟩ cross ⟨9, –6⟩ = 15
⟨–2, 3⟩ cross ⟨–6, –4⟩ = 26
⟨–5, 4⟩ cross ⟨–4, –2⟩ = 26
⟨3, –5⟩ and ⟨6, –10⟩
