Answer:
3x-2
Step-by-step explanation:
Answer:
The numbers are 36 and 68.
Step-by-step explanation:
Let the smaller number be x.
"The larger number is four less than two times the smaller
number."
The larger number is
2x - 4
The sum of the numbers is x + 2x - 4, or 3x - 4.
"The sum of the numbers is 104."
3x - 4 = 104
3x = 108
x = 36
The smaller number is 36.
The larger number is 2x - 4, or
2x - 4 = 2(36) - 4 = 72 - 4 = 68
The larger number is 68.
Answer: The numbers are 36 and 68.
Answer:
Concave down
Y-intercept: (0,-3)
X-intercepts: (-1,0) (-3,0)
Vertex: (-2,1)
Answer:
slope intercept form is y=mx+b.
The "m" in slope intercept form is the number that represents the slope of the line. Think "m for movement" from any point to another.
The "b" in the equation is number that is the y-intercept. The y-intercept is the y-value when x = 0, or where the line crosses the y-axis. think "b for begin" on y-axis.
Substitute the numbers given in the problem into the form of the equation.
m is 4
b is 2
leave the x and the y because you need them so you can have a representation of all the points on the line.
