Answer:

see below and attached

Step-by-step explanation:

To solve a system of quadratic equations:

  • Equal the equations then rearrange so that it is set to zero.
  • Use the quadratic formula to solve.

I have done this (see attached workings) but cannot get any of the solutions you've provided.  I have even graphed the two functions, and the points of intersection concur with my workings (see attached graph).

Is x = -7, the solution to -11 + 2x = -26? Justify your answer in complete sentences.
Natali5045456 [20]
First of all, you can move the +2x to the other side:
-11 = -26 - 2x

Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
 15 = -2x

Then you can divide both sides by 2:
7.5 = -x

Then you can flip the sides and the signs around:
x = -7.5

No, The answer is not -7, it is -7.5
Hope this helps! :)

Please help with simplifying 2|-16.75|
klio [65]
First find the absolute value of -16.75. |-16.75|= 16.75

Then multiply that by 2. 16.75x2=33.5

So 2|-16.75| simplified is 33.5
