Answer:
The answer is 8
- 3 + 2 - =<u> 4 </u> + <u>2 </u> .
Step-by-step explanation:
Given:
8x - 3x + 2 -x = __ x + __
Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.
So, to solve the equation:
So, we add the variables:
And, then subtract it:
Thus, it remains:
.
So the complete equation is:
8 - 3 + 2 - =<u> 4 </u> + <u>2 </u>
Therefore, the answer is 8 - 3 + 2 - =<u> 4 </u> + <u>2 </u> .

Answer:
Since this is a right triangle with one angle and hypotenuse given and opposite side unknown, we can use the definition of sine to find the unknown side.
sin 17 = x/hypotenuse = x/19
x = 19sin17 = 5.6
Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
Difference means subtract so you would subtract 10-9.5 which would give you .5 so the difference would be .5
Although you have not included the statements about the solution to the set of the given equations, I can explain you what happen with that system.
You can arrive to the same conclusion by any method of solution of systems that you like.
The quickest in this case, is to multiply the equation of the lIne F by 5.
That leads to: 5 (x + y) = 5(8)
⇒ 5x + 5y = 40.
Now you can realize that the two representations (equations) correspond to the same line.
That means that there are infinite solutions, this is infinity values of x and y meet both equations.
If you graph line E and line F they overlap in the entire domain, so the graphing method also tells you that you cannot find one solution but infinite soluttions.
