If the -1 is not included, then your answer is 3.17.
2(3x-4)=11
3x2=6 and -4x2= -8
6x-8=11
+8 +8
6x=19
/6 /6
X= 3.17

Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ) and (1, 0 )
4.4
Step-by-step explanation:
X is inversely proportional to y, so x = k/y where k is just a constant.
X is directly proportional to z squared, so x = kz^2 where k is a constant
Here, The second relationship doesn't even matter.
Plug the values for x and y into the first equation and solve for k.
5.5=k/4
k=5.5*4
k=22
Now plug k and the second y back in.
x=22/5
x=4.4
