Answer:
x= 5
Step-by-step explanation:
first we open brackets
12x-8=52
then transpose
12x= 52+8
12x= 60
x= 60/12
x= 5
hope it helps , pls mark me as brainliest
Answer: 81.66 or 81.6
Step-by-step explanation:
The answer to this question is 4y+4
<span>Given the quadratic equation: f(x) = -2x^2 - 2x - 1, the axis of symmetry can be obtained by finding the line that divides the function into two congruent or identical halves. Thus, it should pass through the vertex and is equal
to the x-coordinate of the vertex. </span>
<span>Note that a quadratic
equation in standard form: y = ax^2 + bx + c, has the vertex located at (h,k) where, h = -b/2a and k is determined by evaluating y at
h. In this case, a = -2, b = -2, thus, h = -0.5, k = 0.5. Thus, the vertex is located at (-0.5, 0.5) and the axis of symmetry is at x = -0.5. </span>
The vertex would be (-2,4)
