Hey there, Byanatwin2!

To solve this inequality, we need to isolate x, like any other equation or inequality.
So, to isolate x we need to divide both sides by - \frac{2}{3}

NOTE: We are dividing by a number less than 0, or a negative number so
the sign > will change to <

Now, to divide a fraction, we need to do the reciprocal and then multiply. The reciprocal of - \frac{2}{3} is - \frac{3}{2}
Then, we multiply 8 times - \frac{3}{2} and we get a total of -12
So the answer should be x < -12

If f(x)=7-3x and g(x)=3x-7, what is the value of f(1)-g(1)?
postnew [5]
Substitute 1 for x in each of your equations.

f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4

Then subtract g(x) from f(x):
3-(-4)
=7

X^2+7x+12=0<br> Algebraic proofs <br> Solve each equation, write a reason for every step.
lord [1]

Answer:

x = -3, or x  = -4 is the solution for the given algebraic expression x^{2}  + 7x + 12 = 0

Step-by-step explanation:

Here, the given algebraic equation is:

x^{2}  + 7x + 12 = 0

Now, solving this expression by splitting the middle term, we get

x^{2}  + 7x + 12 = 0   \implies x^{2}  + 3x + 4x + 12 = 0

⇒ x ( x+3) + x (x+3) = 0

⇒(x+3) (x+4) = 0

⇒ either (x+3) = 0, or (x+4) = 0

Hence, either x = - 3, or x  = - 4

Hence, x = -3, or x  = -4 is the solution for the given algebraic expression x^{2}  + 7x + 12 = 0
