Answer:
The point crosses over the y-axis
Step-by-step explanation:
Given
A change in the sign of x coordinate
Required
The effect on the point location
Assume the coordinate to be (x,y).
The above point is located in the first quadrant,
When the x value changes to negative i.e. (-x,y)
The point moves from the first quadrant to the second quadrant
This implies that, the point crosses over the y-axis.
Similarly, assume the coordinate to be (-x,-y).
The above point is located in the third quadrant,
When the x value changes i.e. (x,-y)
The point moves from the first quadrant to the fourth quadrant
This implies that, the point crosses over the y-axis.
7+2x /3 = 5
Thx.......................
Answer:
x= -3
Step-by-step explanation:
7+[tex]\frac{2x}{3}[/tex] = 5
21+2x=15
2x=-6
x= -3
Answer:
x=-3
Step-by-step explanation:
Use PEMDAS to solve. Balance both sides by subtracting 7 from both sides. Then, multiply both sides by 3. Finally, divide the result by 2 to isolate x and you end up with x=-3

What is the probability of landing on red and rolling a number greater than 2?
Answer:
the probability of rolling a number greater than 2 is 2/3
Step-by-step explanation:
because 3 4 5 and 6 are greater than two we have 4 numbers greater than 2 so 4/6 is 2/3 when simplified

warm up:Area.how many square units will it take to fill up this rectangle?
Answer:
12
Step-by-step explanation:
here's your solution
=> area of rectangle = length*width
=> area 4*3 = 12.squnit
=> area of square = side^2
=> area = 1.squnit
=> Number of square = area of rectangle/area of square
=> no of square = 12/1
=>. 12
7/12 = 3x/9
In the equation above, what is the value of x?
A. 4/7
B. 4/21
C. 1 3/4
D. 5 1/4
Don’t link any websites please.
Answer:
C. x = 1 3/4
Step-by-step explanation:
7/12 * 9 = 3x/9 * 9
63/12 = 3x -->
(63/12) / 3 = 3x / 3
63/36 = x
x = 7/4 --> 1 3/4
Please help me with this trigonometry work!
Answer:
We have a triangle rectangle here.
We know that:
AC = 15
BC = 8
AB = 17
We know that in a triangle rectangle the longest side is the hypotenuse.
In the image we can see that the shorter side is the base, then BC is the base.
AC is the height.
AB is the hypotenuse.
Such that:
A is the top vertex.
B is the bottom right vertex
C is the bottom left vertex.
Now you need to remember the relations:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Cos(θ) = (adjacent cathetus)/(hypotenuse)
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
then:
Sin (A) = (AC)/(AB) = 15/17 = 0.88
Cos(B) = (AC)/(AB) = 15/17 = 0.88
Tan(B) = (AC)/(CB) = 15/8 = 1.875
Now we want to find the measure of angle A.
We know that:
Sin(A) = 0.88
Then if we apply the Asin( ) function in both sides, we get:
Asin( Sin(A)) = Asin(0.88)
A = Asin(0.88) = 61.6°
(the Asin() function is the inverse of the sin() function)
Now we have:
sin(x) = 0.906
We do the same thing as before.
Asin(sin(x)) = Asin(0.906)
x = Asin(0.906) = 65°
And:
Sin(87°) = 0.999
Steps included or some steps, thank you!

mike is training to run a marathon. currently, he can run 4 miles in 44 minutes. if he maintains this running speed, how long will it take him to run 10 miles?
Answer:
110 minutes or 1 hour 50 minutes
Step-by-step explanation:
44 divided into 4 since we want to find out how much time it takes to run 1 mile, so 44 divided into 4 is 11
then simply multiply 11 with 10 and the answer is 110

prove the above question and i will give you....
Answer:
see explanation
Step-by-step explanation:
Using the identity
cos²A - sin²B = cos(A + B) . cos(A - B)
Here A = [tex]\frac{\pi }{8}[/tex] + [tex]\frac{A}{2}[/tex] , B = [tex]\frac{\pi }{8}[/tex] - [tex]\frac{A}{2}[/tex]
Consider the left side
cos²([tex]\frac{\pi }{8}[/tex] + [tex]\frac{A}{2}[/tex] ) - sin²( [tex]\frac{\pi }{8}[/tex] - [tex]\frac{A}{2}[/tex] )
= cos([tex]\frac{\pi }{8}[/tex] + [tex]\frac{A}{2}[/tex] + [tex]\frac{\pi }{8}[/tex] - [tex]\frac{A}{2}[/tex] ) × cos([tex]\frac{\pi }{8}[/tex] + [tex]\frac{A}{2}[/tex] - [tex]\frac{\pi }{8}[/tex] + [tex]\frac{A}{2}[/tex] )
= cos ([tex]\frac{\pi }{4}[/tex] ) × cos ( A)
= [tex]\frac{1}{\sqrt{2} }[/tex] cosA
= right side , thus proven

PLEASE HELP FAST!!!!!!!!!
Answer:
132 degrees
Step-by-step explanation:
To solve this problem, you need to know a couple of rules
1) Inscribed angle theroem: when an angle is inscribed in a circle and touches the other end (as opposed to ending at the diameter of the circle), the measure of this angle is half of the measure of the arc.
2)Angles of a quadrilateral shape add up to 360 degrees.
3) The angles inside a circle and the angles of the circles arclength adds up to 360 degrees.
So first, solve angle S with inscribed angle theorem. 126/2 = 63
Then, use the rule that all arc angles in a circle add up to 360 degrees to find the arc angle from Q to S. 360-90-126 = 144. Now find angle P with inscribed angle theorem by doing 144/2 = 72.
Now, use the rule that all angles in a quadrilateral add up to 360 to find R. 360-93-72-63 = 132.
Let me know if this doesn't work, I'll look at it again.
