It pretty much looks like a one to one function. Plot the graph then draw a horizontal line,if the line touches the graph at just one point then it is
Answer: X < -3
Step-by-step explanation:
-15x - 3 > 42
-15x - 3 + 3 > 42 + 3
-15x > 45
-15x/-15 > 45/-15
Since we are dividing by a negative, we flip the >
x < -3
So, let's check
-4 < -3
-15*-4 - 3 > 42
60 - 3 > 42
57 > 42
Now, let's see if -3 will work.
-15*-3 - 3 > 42
45 - 3 > 42
42 > 42 (False)
Okay, now let's try 4
-15*4 - 3 > 42
-60 - 3 > 42
-63 > 42
This is false, so it is x < -3
hi
if the twi lines are parallel , they have the same slope.
So slope is 1/2.
equation of a line is : mx +p
The line goes throught (-2 ; 4)
We have 1/2 ( -2) + p = 4
- 2/2 +p = 4
-1 +p = 4
p = 4+1
p = 5
equation of the line is y = 1/2x +5
Answer:
x=8
x=3
Step-by-step explanation:
f(x) = −4(x − 8)² + 3
h(x)= -(x-3)² + 2
- <em>The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.</em>
f(x) = −4(x − 8)² + 3
for the first function, the vertex is:
- x-8=0 ⇒ x= 8, this is the axis of symmetry
h(x)= -(x-3)² + 2
for the second function, the vertex is:
- x-3= 0 ⇒ x=3, this is the axis of symmetry, it is also visible on the graph
