To find the y intercept you must substitute 0 into x.
F(x) = (-3x0) - (6x0) - 5
F(x) = -5
To find the axis of symmetry and vertex we use the formula -b/2a to find the x coordinate
x = 6/(-3x2)
x = 6/-6
x = -1
Now we need to find the y coordinate so we sub -1 into x.
F(x) = (-3x-1) - (6x-1) - 5
F(x) = 3 + 6 - 5
F(x) = 4
The axis of symmetry and vertex are (-1,4) and the y coordinate is -5. Hope this helps.
Answer: The linear system of equations that models this scenario are
T + B = 15
3T + 2B = 38
Step-by-step explanation:
Let T represent the number of tricycles.
Let B represents the number of bicycles ordered.
The recreation center ordered a total of 15 tricycles and bicycles from a sporting good store. It is expressed as
T + B = 15
A tricycle has three wheels. A bicycle has 2 wheels. The number of wheels for all tricycles and bicycles total 38. The expression would be
3T + 2B = 38
For an equation to be proportional, it must have no y intercept, and it must have a slope. So,
<span>y=4x+4 This equation isn't proportional because it has a y-intercept (+4)
y=4x+2 </span>This equation isn't proportional because it has a y-intercept (+2)
y=4x This equation is proportional because it has no y-intercept, and a slope.
It is not equal to 8 but it is the reciprocal of it.
Answer:
3
Step-by-step explanation:
If is 3, then
Both and equal 3. So, the value of must be 3 for the function to have the same coordinate for and .
