Answer:
Step-by-step explanation:
-0.5
Step-by-step explanation:
If x is 1, plug it into the equation.
So, y=-3(1) + 2.5
-3(1) = -3
now add.
-3+2.5 = -0.5
so that should give you y = -0.5
<h3>Answer:</h3><h2>It's a </h2><h3>You can go with it</h3><h3>Step-by-step explanation:</h3>
Y < 2x + 4.....u have a dashed line with shading below the line....u have a y int of (0,4)...u have an x int of (-2,0) and a slope of 2
y > -x - 3...u have a dashed line with shading above the line....u have a y int of (0,-3) and an x int of (-3,0) and a slope of -1
ur graph is : There is a problem....it will either be the 2nd one or the 3rd one....because one of ur inequalities is written incorrectly...
** IF y > -x - 3 is supposed to have an equal sign in there...then ur answer is the 2nd graph
** IF y < 2x + 4 is supposed to have an equal sign in there...then ur answer is the 3rd graph
Answer:
Step-by-step explanation:
Universal set contains all elements and of which all other sets are subsets.
Question 1
The given system of equations is:
Equate the two equations:
Rewrite in standard form:
When we put x=0, in y=3x +6, we get:
One solution is (0,6)
When we put x=-2, into y=3x+6, we get:
Another solution is (-2,0)
The solutions are; (0,6) and (-2,0)
Question 2:
The function is
Let us put x=-x,
This gives:
We can observe that:
This is the property of an even function.
Question 3:
The given function is
The average rate of change of f(x) from x=a to x=b is given as:
This is the slope of the secant line connecting the two points on f(x)
From x=2 to x=6, the average rate of change
The average rate of change is 11
