Answer:

Step-by-step explanation:

Well you have to solve for X to find Y simplified.

Since both equations equal Y you can plug them together

3x+3=x-1

-x -x

2x+3=-1

-3 -3

2x=-4

Divide -4 by 2 and you get X = -2 then plug X into both equations and boom

y= -3

Use substitution
Given both y values, you know that they have to be equal

3x + 3 = x - 1
2x + 3 = -1
2x = -4, divide by 2
x = -2
Now plug x value into any of the equation to find y value
y = 3(-2) + 3
y = -6 + 3, y = -3

Solution: x = -2, y = -3

A committee consisting of 4 faculty members and 5 students is to be formed. Every committee position has the same duties and vot

Zina [86]

Answer:

The number of ways to form the committee is formed = 637065

Solution:

The number of combinations of n things such that m things taken together are given by:-

$C_{(\boldsymbol{n}, \boldsymbol{m})}=\frac{n !}{m !(\boldsymbol{n}-\boldsymbol{m}) !}$

Given Data:

A committee consisting of 4 faculty members and 5 students is to be formed. There are 12 faculty members and 13 students eligible to serve on the committee.

Then, the number of ways to form the committee is formed given by :-

$\begin{array}{l}{12 C_{4} \times 13 C_{5}} \\\\ {=\frac{12 !}{4 !(12-4) !} \times \frac{13 !}{5 !(13-5) !}} \\\\ {=\frac{12 !}{4 ! 8 !} \times \frac{13 !}{5 ! 8 !}} \\\\ {\frac{12 \times 11 \times 10 \times 9 \times 8 !}{27 \times 8 !} \times \frac{13 \times 12 \times 11 \times 10 \times 9 \times 8}{120 \times 8 !}} \\\\ {=637065}\end{array}$

Hence, the number of ways to form the committee is formed = 637065

A bowl of spaghetti contains 5 grams of fiber. It is recommended for a person to eat 34 grams of fiber in a day. If you ate 3.5

puteri [66]

Answer: 51 %

Step-by-step explanation:

3.5 * 5 = 17.5

17.5 = x/100 * 34

17.5 = 34x/100

17.5 * 100 = 34x

1750 = 34x

x = 1750/34

x = 51.47

rounded to 51%
