All you need to do it combine like terms.
3x + 9 + 4x + x
(3x + 4x + x) + 9
8x + 9
i hope this was helpful for you!
y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution.
The coordinates of point of intersection (7,-12)
Answer:
B. a = 4, b = -8, c = -3
Step-by-step explanation:
The quadratic equation given is:

The general form of a quadratic equation is given as:

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

Therefore, by comparing:
a = 4
b = -8
c = -3
The correct option is B
Answer:
Step-by-step explanation:
The slope would be determined either by a graph or a equation
