Rate of change y=5x+10
frozen [14]

Answer:

5

Step-by-step explanation:

The equation y=5x+10 is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format y=mx+b, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

y = mx + b\\\\m=slope\\b = y-intercept.

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation y=5x+10 is given in the slope-intercept form, and the coefficient (m) equals (5), therefore the slope is (5).

What is the answer to this math problem
shutvik [7]
Y + x = 5x + 3
12 - y = x + 2y

Isolate x in the first equation, then substitute its expression into the second equation to find y:

y + x = 5x + 3
x = 5x - y + 3
-4x = -y + 3
x = y - 3/4

---

12 - y = x + 2y
12 - y = (y - 3/4) + 2y
48 - 4y = y - 3 + 8y
48 - 4y = 9y - 3
-4y = 9y -51
-13y = -51
y = 51/13

Substitute this into the first equation to find x:

51/13 + x = 5x + 3
x - 5x = 3 - 51/13
-4x = -12/13
x = 3/13

Lastly, substitute back into both original equations to check work;

y + x = 5x + 3   -->   51/13 + 3/13 = 5(3/13) + 3  -->  54/13 = 54/13
12 - y = x + 2y   -->   12 - 51/13 = 3/13 + 2(51/13)  -->  105/13 = 105/13

Answer:
x = 3/13
y = 51/13

Hope this helps.
