Answer:
the value of x=
2×-12= -24
the value of y is 3y plus 20 which equals to 23
C and B is proportional relationships , because the proportional relationships always start at zero and the line must be straight !
Answer:
<em>Option C</em>
Step-by-step explanation:
Consider each of these graphs. Let us formulate an inequality for each of them, and match the one with an inequality of
;
![Graph 1, x > 13.5\\Graph 2, x \geq 14\\Graph 3, x > 14.5\\Graph 4, x \geq 15](https://tex.z-dn.net/?f=Graph%201%2C%20x%20%3E%2013.5%5C%5CGraph%202%2C%20x%20%5Cgeq%2014%5C%5CGraph%203%2C%20x%20%3E%2014.5%5C%5CGraph%204%2C%20x%20%5Cgeq%2015)
Graph 3 is the only one that matches with the inequality provided to us.
* Note that shaded circles are represented by a greater / less than or equal to, and non - shaded circles are represented by a greater / less than sign.
<em>Solution ⇒ Graph 3</em>
X=y-2
2y=5x-17
Substituting for x into the second equation, we find
2y=5(y-2)-17
2y=5y-10-17
-3y=-27
y=9
So x=7
Thus, the two numbers are 7 and 9.
Answer:
The answer for this problem is
