How do you graph y=-1.5<img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20" id="TexFormula1" title=" x^{2} " alt=" x^{2} " align
lorasvet [3.4K]
y=-1.5 x^{2} +6 \\ \\ x=-3 \Rightarrow y=-1.5*(-3)^2+6 =-1.5*9+6=-13.5+6=-7.5\\ \\x=-2 \Rightarrow y=-1.5*(-2)^2+6 =-1.5*4+6=-6+6=0\\ \\x=-1 \Rightarrow y=-1.5*(-1)^2+6 =-1.5*1+6=-1.5+6=-4.5\\ \\x=0 \Rightarrow y=-1.5*0^2+6 =6

x=1 \Rightarrow y=-1.5*(1)^2+6 =-1.5+6=-4.5\\ \\ x= 2 \Rightarrow y=-1.5*2^2+6 =-1.5*4+6=-6+6=0\\ \\x=3 \Rightarrow y=-1.5*3^2+6 =-1.5*9+6=-13.5+6=-7.5

Item 6 for what value of a is 8x−8+3ax=5ax−2a an identity?
Readme [11.4K]

Let's rewrite the expression as

8x+3ax-5ax = 8-2a \iff 8x - 2ax = 8-2a \iff 2x(4-a) = 2(4-a)

So, if a \neq 4, you may divide both sides by 4-a, the equation becomes 2x=2, and the only solution is x=1, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).

If instead a = 4, you are multiplying both sides by zero, so the equation becomes

2x \cdot 0 = 2 \cdot 0 \iff 0=0

So, it doesn't matter which value for x you choose, because you will always end up with 0=0, which is obviously always true.
