4x+6+3=17
4x+9(add the 6 and 3)=17
4x=8(subtract 9 from each side 4x+9-9=17-9)
x=2(divide each side by 4, 4x/4=8/4)
2 is the final answer.
You can check your work...
4(2)+6+3=17
8+6+3=17
14+3=17
17=17
So this is correct!!! Hope this helps you.
Answer:
-50xy
-40x²
Step-by-step explanation:
1. The greatest common of the variable is the variable with the lowest exponent, as you can see, the exponents are: 3,2 and 1. The lowest exponent is 1, then, it is x.
2. The greatest common factor of the coefficients is 2, because all of them are divisible by 2.
3. Therefore, you can add a term that has the greatest common factor 2x. This means that the term must have the variable "x" and the coefficient must be divisible by 2:
4. The terms -50xy and -40x² has the greatest common factor 2x.
The answer is
1.6x-(x-2.8)=(0.2x+1.5)-0.7
1.5-0.7
1.6x-(x-2.8)=0.2x+0.8
1.6x-x
0.6x+2.8=0.2x+0.8
2.8-2.8 0.8-2.8
0.6x=0.2x-2
0.6x-0.2x 0.2x-0.2x
0.4x=-2
0.4x/0.4 -2/0.4
X=-5
If we use a graphing tool, we can plot both graphs and find the solution quickly
<span>g(x)=x^2+2x-8</span> =7 =f(x)
The solutions are x1 =-5 , x2 = 3
