Answers
Answer:
D, 110$
Step-by-step explanation:
According to the systematic function, given that the bill as a function is equal to one tenth the quantity of x for kilowatt hours less than or equal to 200, and three twentieths of 200 less than the quantity of x plus 20 for kilowatt hours greater than 200. The answer is 110$ because the question gives us a measure of kilowatts greater than 200 so the second equation is used in the system. Therefore .15(800-200) + 20 = b(800), (.15)600 +20 = 90 + 20 = 110

Using the trig. identity
sin²x + cos²x = 1 ⇒ cosx = ± [tex]\sqrt{1-sin^2x}[/tex]
Here sinθ = [tex]\frac{1}{2}[/tex] , thus
cosθ = ± [tex]\sqrt{1-(\frac{1}{2})^2 }[/tex] = ± [tex]\sqrt{1-\frac{1}{4} }[/tex] = ± [tex]\sqrt{\frac{3}{4} }[/tex] = ± [tex]\frac{\sqrt{3} }{2}[/tex]
Since 0 ≤ θ > 90 then cosθ > 0 , thus
cosθ = [tex]\frac{\sqrt{3} }{2}[/tex] → C

Which is the solution to the following system x+2y+z=9
X-y+3z=13
2z=10
Answers
Step-by-step explanation:
I'm not sure but,here you go
2z = 10
z = 10 ÷ 2 = 5
x + 2y + z = 9
x + y + 3z = 13
____________
x + 2y + 5 = 9
x + y + 3(5) = 13
_____________
x + 2y = 9 - 5
x + y = 13 - 15
___________
x + 2y = 4
x + y = -2 (×-1)
___________
x + 2y = 4
-x - y = 2
___________
y = 6
x = -2y - z + 9 = -2(6) - 5 + 9 = -12 - 5 + 9 = -8
If you wanna check,
x + y +3z = 13
(-8) + 6 + 3(5) = 13
x = -8 , y = 6 , z = 5
I'm not very sure but here you go,I might be wrong^^
/2 on both sides
z = 5
———————
x + 2y + z = 9
x + 2y + 5 = 9
-5 on both sides
x + 2y = 4
———————
x - y + 3z = 13
x - y + 3(5) = 13
x - y + 15 = 13
-15 on both sides
x - y = -2
———————
x + 2y = 4
x - y = -2
x + 2y = 4
- (x - y = -2)
x + 2y = 4
-x + y = 2
Add the equation together
3y = 6
/3 on both sides
y = 3
———————
Substitute z = 5 and y = 3 in one of the equations that includes all of the variables
x + 2y + z = 9
x + 2(3) + 5 = 9
x + 6 + 5 = 9
x + 11 = 9
-11 on both sides
x = -2
———————
Answers:
x = -2
y = 3

A. -4
B. -3/2
C.2/3
D.6
Answers
Answer:
A. -4
Step-by-step explanation:
For solving for x intercepts analytically. You can set the the y in the equation to 0. So, 2x-3(0)=12, and solving for x will get you -4.
You can also solve graphically by plugging in the equation and looking at where it intercepts the x axis.

The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answers
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )
