Assuming your asking for two sets of systems of equations.

#1: {y,x}={-1,-1}

Steps:

Solve by Substitution :

// Solve equation [2] for the variable  x

[2]    x = -y - 2

// Plug this in for variable  x  in equation [1]

[1]    y - 4•(-y -2) = 3

  [1]    5y = -5

// Solve equation [1] for the variable  y

  [1]    5y = - 5

 [1]    y = - 1

// By now we know this much :

  y = -1

   x = -y-2

// Use the  y  value to solve for  x

x = -(-1)-2 = -1

Solution :

{y,x} = {-1,-1}

2: {y,x}={3,-1}

Steps:

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -y + 2

// Plug this in for variable  x  in equation [1]

 [1]    y + 6•(-y +2) = -3

  [1]    -5y = -15

// Solve equation [1] for the variable  y

[1]    5y = 15

[1]    y = 3

// By now we know this much :

y = 3

x = -y+2

// Use the  y  value to solve for  x

x = -(3)+2 = -1

Solution :

{y,x} = {3,-1}

Abby, Bik, Cari, Dawn, and Ellen collect T-shirts. Abby has the most. Bik has 2.5 times as many T-shirts as Cari. Dawn has 1/3 a
bixtya [17]
A=abby's shirts
b=bik's shirts
c=cari's shirts
d=dawn's shirts
e=ellen's shirts


a> everybody
b=2.5c
d=(1/3)c
a+b+c+d=120
e=2d+1
e=13
oook

e=13=2d+1
13=2d+1
12=2d
d=6

d=(1/3)c
6=(1/3)c
18=c

b=2.5c
b=2.5(18)
b=45

a+b+c+d=120
a+45+18+6=120
a+69=120
a=51

I’ll give brainliest pls help
andrew11 [14]

Answer:

The slopes of WX and XZ

Step-by-step explanation:

The singular factor that determines if the parallelogram is a rectangle are the angles at the edges

Mathematically, we can only have a rectangle if there are four right angles with one right angle each at the edges of the rectangle

So, by having the slope of the sides forming the width and that which forms the length, we can deduce if what we have is rectangle given that the slopes will yield a perpendicular product

Hence, the slopes of WX and XZ can be calculated to show this

The reproduction function for a sardine is f(p) = −0.0005p2 + 4p, where p and f(p) are in hundred metric tons. Find the populati
tensa zangetsu [6.8K]

Answer:

Population (p) = 4,000 hundred metric tons

Size of the yield (f(p)) = 8,000 hundred metric tons

Step-by-step explanation:

The population of sardines 'p', for which the derivate of the function f(p) is zero, is the population that gives the maximum sustainable yield:

f(p) = -0.0005p^2 + 4p\\\frac{df(p)}{dp}=-0.0010p+4\\-0.0010p+4 =0\\p=4,000

The size of the maximum sustainable yield is:

f(p) = -0.0005p^2 + 4p\\f(4,000) = -0.0005(4,000^2) + 4*4,000\\f(4,000) = 8,000

Population = 4,000 hundred metric tons

Size of the yield = 8,000 hundred metric tons
