hi thanks
Step-by-step explanation:
<span>x+9=2x+1
Since both equations give the value of y, therefor y = y. You simply substitute y with its corresponding equation.
y = y
x + 9 = 2x + 1 *we need to find the value of x to get the value of y.
x - 2x = 1 - 9
-x = -8
-1x/-1 = -8/-1
x = 8
Substitute x with its value to get y.
Equation S: y = x + 9 </span>⇒ y = 8 + 9 ⇒ y = 17
Equation T: y = 2x + 1 ⇒ y = 2(8) + 1 ⇒ y = 16 + 1 ⇒ y = 17
<span>x+9=2x+1
</span>17 = 17
Answer:
You have to put energy into a molecule to break its chemical bonds. The amount needed is called the bond energy. After all, molecules don't spontaneously break

Step-by-step explanation:
rise over run the y-intercept is 3 and you go down 4 and run 3
4 x = 36
Step-by-step explanation:
Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.
Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.
Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..
4x = 36
