Answer:
, D
Step-by-step explanation:
3 if x is greater than or equal to 1 is nothing. That leaves us with
if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is
, which is D.
Average rate of change from x = -3 to x = 1 is (f(1) - f(-3))/(1 - (-3)) = (5 - (-3))/(1 + 3) = (5 + 3)/4 = 8/4 = 2
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula
Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
Answer:
Trapezoid
Step-by-step explanation:
perpendicular: They are perpendicular due to the fact they cross at right angles to each other. Another true instance of perpendicular lines we will see in nature is a football field. All four corners of a football field are perpendicular to every other.
In the trapezoid attached there aren't any perpendicular sides. A and B are both obtuse angles in this diagram, and C and D are both acute angles. However, now not all trapezoids appear like this. ... Definition B: A trapezoid is any quadrilateral with at the least one pair of parallel sides.
