PLS HELP LAST DAY OF APEX a.graph this system of inequalities y<-x+4 y>-x-2 b. How many solutions does this system of ineq
ualities have?
1 answer:
Answer:
Part ) The graph in the attached figure
Part b) The system has infinitely solutions
Step-by-step explanation:
Part a) Graph this system of inequalities
we have
y < -x+4 -----> inequality A
The solution of the inequality A is the shaded area below the dotted line
y=-x+4
The y-intercept of the dotted line is the point (0,4)
The x-intercept of the dotted line is the point (4,0)
The slope of the dotted line is negative (m=-1)
y > -x-2 -----> inequality B
The solution of the inequality B is the shaded area above the dotted line
y=-x-2
The y-intercept of the dotted line is the point (0,-2)
The x-intercept of the dotted line is the point (-2,0)
The slope of the dotted line is negative (m=-1)
using a graphing tool
The graph in the attached figure
Part b) How many solutions does this system of inequalities have?
we know that
The solution of the system of inequalities is the shaded area between the two dotted lines (see the attached figure)
therefore
The system has infinitely solutions

The function which is same as the function y = 3cos(2(x +π/2)) -2 is: Option A: y= 3sin(2(x + π/4)) - 2
<h3>How to convert sine of an angle to some angle of cosine?</h3>We can use the fact that:
to convert the sine to cosine.
<h3>Which trigonometric functions are positive in which quadrant?</h3>- In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
- In second quadrant(π/2 < θ < π), only sin and cosec are positive.
- In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
- In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
(this all positive negative refers to the fact that if you use given angle as input to these functions, then what sign will these functions will evaluate based on in which quadrant does the given angle lies.)
Here, the given function is:
The options are:
Checking all the options one by one:
- Option 1:
(the last second step was the use of the fact that cos flips its sign after pi radian increment in its input)
Thus, this option is same as the given function.
- Option 2:
This option if would be true, then from option 1 and this option, we'd get:
which isn't true for all values of x.
Thus, this option is not same as the given function.
- Option 3:
The given function is
This option's function simplifies as:
Thus, this option isn't true since always (they are equal for some values of x but not for all).
- Option 4:
The given function simplifies to:
The given option simplifies to:
Thus, this function is not same as the given function.
Thus, the function which is same as the function y = 3cos(2(x +π/2)) -2 is: Option A: y= 3sin(2(x + π/4)) - 2
