Answer:
54
Step-by-step explanation:
total no. of marbles=100
no. of marbles Marcy had
=25% of 100
=25/100×100
=25
no. of marbles Roger had=21
Let the no. of marbles Ann had=x.
So, 25+21+x=100
46+x=100
x=100-46=54
Therefore, Ann had 54 marbles at the end of the game.
Put these numbers in order from greatest to least.

Answer (if we're solving for x):
[tex]x=-7[/tex] or [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Rearrange the terms from [tex]2x^{2} =63-5x[/tex] to [tex]2x^{2}=-5x+63[/tex]Move the terms to the left side: [tex]2x^{2}-(-5x+63)=0[/tex]Use the "sum-product" pattern: [tex]2x^2+14x-9x-63=0[/tex]Get the common factor drom the 2 pairs:[tex]2x(x+7)-9(x+7)=0[/tex]Rewrite the equation in factored form as [tex](2x-9)(x+7)=0[/tex]Create 2 equations from [tex](2x-9)(x+7)=0[/tex]: [tex]2x-9=0\\x+7=0[/tex]This means that [tex]x[/tex] can either be [tex]-7 (-7+7=0=x+7)[/tex] or [tex]\frac{9}{2} (\frac{8}{2}=4; \frac{9}{2}=4.5)[/tex]Which of the following relations represent a function?

Answer:
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Sofia calculated the circumference and area of a circle with a radius of 4.
C=2πr
=2(3.14)4
=25.12
A=πr2
=3.14(4)2
She then said, “The value of the circumference of a circle is always half the value of its area.” Is Sofia correct? Justify your answer.
Answer:
the circumference is 25.12
Someone help and please make sure the answer is right
Answer:
This is the exterior angle theorem, so
x+30+x+22=130
2x+52=130
2x=78
x=39
sooooooooooooo
39+22=61 degrees
61 degrees
Answer:
21
Step-by-step explanation:
First set up the equation
130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)
then start to solve to find x
130 +2x + 30 + 22 = 180
182 + 2x = 180
-182 -182
2x = -2
/2 /2
x = -1
Then just plug it back into the equation
-1 + 22

SOMEONE HELP ME PLEASE 30 POINTS
Answer:
D. (+,-)
Step-by-step explanation:
Map it out!
Quadrant I's points will always be (+,+). It is located in the upper right section.
Quadrant II's points will always be (-,+). It is located in the upper left section.
Quadrant III's points will always be (-,-). It is located in the lower left section.
Quadrant IV's points will always be (+,-). It is located in the lower right section.
The x-coordinate and y-coordinate are both negative, which is the right statement. The best choice is B.
When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.
The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.
As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.
