7. Marcy is taking part in a summer movie club. She will
earn 3 points for each movie she attends throughout the
summer. Which equation represents the relationship
between y, the total points, and x the number of movies?
A y=3x
B. y = 3+x
C. x= 3y
D. x=y+3
Answer:
The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;
A y = 3·x
Step-by-step explanation:
The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie
The number of points she will earn for attending each movie = 3 points
The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;
y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write
[tex]y = \sum\limits_{i =1}^x 3 = 3 \times x[/tex]
Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

For what values of x is the trinomial 2x2−x+55 equal to the square of binomial x+5?
The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6
Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;
2x^2−x+55 = (x+5)^2
2x^2−x+55 = x^2 + 10x + 25
Collect the like terms;
2x^2-x^2-x-10x+55-25 = 0
x^2 - 11x + 30 = 0
Factorize the result
x^2 - 6x - 5x + 30 =0
x(x-6)-5(x-6) = 0
x-5 = 0 and x - 6 = 0
x = 5 and 6
Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

hope this helped
good luck
Please read through this carefully. I’d love to help, but I want you to understand why this is the answer and not just copy and paste.
Answer:
1. -6
2. 20
Step-by-step explanation:
1. Simply replace x with 2, since x=2. 2x -3 is the same as -3+-3, which is -6.
2. Simply replace x with 2, since x=2. 2x5 is the same as 5+5, which is 10. 10+10=20, therefore, the answer is 20.
The diagram shows a square ABCD
M is the midpoint of AB
N is the midpoint of AD
The area of the shaded triangle AMN is 8cm^2
Work out the area of triangle MCN
The area of the triangle, Δ AMN is 8 cm², so the area of the triangle, ΔMCN is 24 cm².
A triangle is one of the most basic geometric figures with 3 sides, 3 angles, and 3 vertices.
The area of a triangle is half of the product of the base and height.
Given that
ABCD is square and M and N are mid-points of lines AB and AD respectively.
Area of triangle, ΔAMN = 8 cm²
[tex]\dfrac{1}{2} \times AN \times AM = 8\\AN \times AM = 8 \times 2\\AN \times AM = 16[/tex] ...(i)
Since ABCD is square, therefore AB = AD.
Also, as M and N are mid-points of lines AB and AD, so
AN = AM.
Substitute AN = AM in equation (i),
[tex]AN \times AN = 16\\AN^2 = 16\\AN = \sqrt{16}\\AN = 4\ cm[/tex]
So,
AD = 2 × AN
= 2 × 4
= 8 cm
As ABCD is square,
AB = BC = CD = AD = 8 cm.
Area of the square ABCD = 8² = 64.
Since CD = BC, ND = MB, ∠D = ∠B.
Therefore by SAS property of similarity,
ΔCDN ≅ ΔCBM
Area of the triangle, ΔCDN = Area of the triangle, ΔCBM.
[tex]= \dfrac{1}{2} \times CB \times BM\\= \dfrac{1}{2} \times 8 \times 4\\\\= 16\ cm^2[/tex]
Area of the triangle, ΔCMN = Area of ABCD - Area of ΔAMN - Area of ΔCDN - Area of ΔCBM
Area of the triangle, ΔCMN = 64 - 8 - 16 - 16
= 24 cm²
Therefore, the area of ΔCMN is 24 cm².

3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Answer:
Median --> 357.5
Q1 --> 298
Q3 --> 422
IQR > 124
Step-by-step explanation:
3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Step 1
We rearrange the given data set
250, 298, 346, 369, 422, 433
a) The Median
The formula to find the Median
= 1/2( n + 1)th term
Where n = Number of terms = 6
Median = 1/2(6 + 1)th
= 1/2(7)th term
= 3.5th term
The 3.5th term = The number between the 3rd and 4th term
3rd term = 346
4th term = 369
Hence,Median = 346 + 369/2
= 357.5
2) Q1 = First Quartile
= 1/4(n + 1)the
= 1/4( n + 1)th term
Where n = Number of terms = 6
Median = 1/4(6 + 1)th
= 1/4(7)th term
= 1.75th term
The 1.75th term = 2nd term
= 298
Q1 = 298
3) 3/4( n + 1)th term
Where n = Number of terms = 6
Median = 3/4(6 + 1)th
= 3/4(7)th term = 21/4th term
= 5.25th term
The 5.25th term = 6th term
Q3 = 422
4) Interquartile Range = Q3 - Q1
= 422 - 398
= 124

Solve the equation sin^2x= 3 cos^2x.
The value of x that satisfies the equation if x lies in the second quadrant is what degrees?
The value of x that satisfies the equation if x lies in the third quadrant is what degrees?
Step-by-step explanation:
sin^2(x)= 3 cos^2(x)
Subtract sin^2(x) on both sides
0=3cos^2(x)-sin^2(x)
By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)
0=3(1-sin^2(x))-sin^2(x)
Distribute
0=3-3sin^2(x)-sin^2(x)
Combine like terms
0=3-4sin^2(x)
Add 4sin^2(x) on both sides
4sin^2(x)=3
Divide both sides by 4
sin^2(x)=3/4
Take the square root of both sides
sin(x)=+ or - sqrt(3/4)
sin(x)=+ or - sqrt(3)/sqrt(4)
sin(x)=+ or - sqrt(3)/2
This happens on the unit circle at
60 degrees
120 degrees
240 degrees
300 degrees
If we go around and around again forwards or backwards, we get the infinitely many other solutions including the one's already stated in the following solution sets
(60 +360n) degrees
(120 +360n)degrees
(240 +360n)degrees
(300 +360n)degrees
where n is an integer
x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.
240 degree one or the (240+360n) degrees terminates in the third.

Answer:
the right answer is:
(A) [tex]2+\frac{1}{2}a[/tex]Step-by-step explanation:
You take the equations that the exercise give you:
x + y = 4x - y = aNow you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
x - y = a-y = a - x3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
x + y = 4x + (x - a) = 4x + x - a = 4Add the x variables:
2x - a = 42x = 4 + ax = (4 + a) / 2That's the answer of the exercise, but you can represent this in this form:
x = (4 + a) / 2 ↔ [tex]x = \frac{4}{2} + \frac{1}{2} a[/tex]x = (4 + a) / 2 ↔ [tex]x = 2+ \frac{1}{2} a[/tex]By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].
