Step-by-step explanation:
<em><u>solve:</u></em>
<u>Subtract 2 from both sides</u>
=6x+2=2x+10
=6x+2-2=2x+10-2
<em><u>Simplify</u></em><em><u>:</u></em>
<u>Subtract the </u><u>numbers</u>
=6x=2x+8
<u>Subtract 2x from both sides</u>
=6x<em>-2x</em>=2x+8<em>-2</em><em>x</em>
<u>Simplify</u><u>:</u>
<u>Combine like terms</u>
=4x=2x+8-2x
4x=8
<u>Divide both sides by the same </u><u>factor</u>
4x=8
4x÷4=x 8÷4=2
<em>ANSWER</em><em>:</em><em> </em><em> </em><em> </em><em> </em>
<em>x</em><em>=</em><em>2</em>
Answer:
2x + y -6 = 0
Step-by-step explanation:
The general form is
. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form. Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.
30^2=a^2+2(a)^2
900=a^2+4a^2
900=5a^2
180=A^2
6√5=a
a=13.4164cm
A is NOT a function because for some values of x you get more than one y value. For example if x=2 you get 2 values for y.
b is a function because for each x you get ONLY one y
