Hey there! :D

-2(k-2)≥-20

Distribute the -2. Multiply -2 by k and -2. 

-2k+4≥-20

Subtract 4 on both sides. 

-2k≥-24

Divide by -2 and flip the sign, since you are dividing by a negative. 

k≤12

I hope this helps!

-2(K-2) > -20 -2(k)= -2k -2(-2)=4 rewrite -2k+4>-20 subtract 4 from both sides -24 rewrite -2k=-24 divide -2 from both sides rewrite k=12
Hope this helps have a nice nite
GENERAL OUT!

Learning Task 1. Group the given equations into two based on observed common properties.
AnnZ [28]

Quadratic Equations in Single Variable

n²-3n+10=0

2x²+2x+1=0

25b²-16=0

f²-3f+2=0

1/3m +2m=4

a²=225

Linear Equation in single Variable

8-3k=12

5w+5=0

10u-5=8

Linear Equation in Two  Variable

2y-z=9

3r+2e=6

d=3e-7

<h3>What is an equation?</h3>

It should be noted that an equation simply means the expression that's used to show the relationship between the variables.

In this case, the equation has been grouped.

Solve the system of linear equations by substitution
ziro4ka [17]

y - x = 0  ...equation 1
2x - 5y = 9 \: ...equation  \: 2
working with equation 1
y = x \: ...equation \:  3
next subsitue equation 3 in equation 1
2x - 5(x) = 9
2x - 5x = 9
- 3x = 9
divide by -3
x =  - 3
substitute x= -3 in equation 1
y - ( - 3) = 0
-(-3) = + 3
y =  - 3

A craftsman can sell 10 jewelry sets for $500 each. He knows
liraira [26]

Answer:15

Step-by-step explanation:

Given

Craftsman sell 10 Jewelry set for $500 each

For each additional set he will decrease the price by $ 25

Suppose he sells n set over 10 set

Earning=\text{Price of each set}\times \text{no of set}

Earning =(500-25n)(10+n)

E=5000+500n-25n^2-250n

differentiate to get the maximum value

\frac{dE}{dn}=-50n+250

Equate \frac{dE}{dn} to get maximum value

-50n+250=0

n=\frac{250}{50}

n=5

Thus must sell 5 extra set to maximize its earnings.
