Answer:
Mrs. Perry
Step-by-step explanation:
find the ratio by dividing the petunias by the daffodils
Ms. H =3
Mr. M = 3.5
mrs. P= 3.75
There'll be 5 parents that'll go to the museum
Let the number of parents that will go to the museum be represented by x.
Based on the information given, the equation to use will be:
15/75 = x/25
Cross multiply
75 × x = 15 × 25
75x = 375
Divide both side by 75
75x/75 = 375/75
x = 5
Therefore, there'll be 5 parents that'll go to the museum.

The answer is: [B]: (13, -5) .
______________________________________________________
Explanation: Using Substitution:
______________________________________________________
y = 8 − x ;
7 = 2 − y ;
___________________________________
Solve for "x" and "y" using using substitution;
_________________________________________
Take the second equation given:
____________________________________________
7 = 2 − y ;
And considering the first equation given: " y = 8 − x " ;
_________________________________________________
Substitute the value: "8 − x" for (the value of "y" in the first equation given), in order to solve for "x" ;
_________________________________________________
7 = 2 − y ;
________________________________________
7 = 2 − 8 − x ;
__________________________________________
7 = -6 − x ;
__________________________________________
Add "6" to EACH side of the equation:
__________________________________________
7 + 6 = -6 − x + 6 ;
__________________________________________
to get: 13 = -x ;
__________________________________________
13 = -x ; ↔ -x = 13 ; ↔ -1 x = 13 ;
___________________________________________
Divide EACH side of the equation by "-1 " ; to isolate "x" on one side of the equation; and to solve for "x" ;
___________________________________________
-1 x / -1 = 13 / -1 ;
___________________________________________
x = 13 . At this point, the only answer choice that can be correct is answer choice: "[B]: (13, -5)" ; since it is the only answer choice given with a solution of x = 13;
___________________________________________
Nonetheless, we shall continue.
___________________________________________
Now that we have the solution for "x"; "x = 13"; We shall plug this value into, or "SUBSTITUTE" this value, "13", for "x", into the first equation given, " y = 8 − x " ; to find the value of "y" ; as follows:
__________________________________________
y = 8 − x ;
____________________________________________
y = 8 − 13 ;
____________________________________________
y = -5 .
_____________________________________________
So, we have x = 13; and y = -5; or write as: (13, -5) . This solution corresponds directly which answer choice: [B]:
__________________________________________________
Also, to confirm, let us plug in our solved value for "y", which is "-5" ; into our second equation, to see if the equation holds true:
_____________________________________________
7 = 2 − y ;
_____________________________________________
7 =? 2 − (-5) ?? ;
_____________________________________________
7 =? 2 + 5 ? ? Yes !
______________________________________________
The degree of the polynomial is 4.
Explanation: Look at the highest degree in the polynomial. The highest degree in the given polynomial is 4. (The 5x^4 contains the highest degree which is, of course, 4.)
I hope this helps.
