Solve 5kx + 6 = 7kx for x.

Mathematics
1 answer:
Slav-nsk [51]3 years ago
4 0

Answer:

5kx + 6 = 7kx  

 

Subtract 6 on both sides  

 

5kx + 6 - 6 = 7kx - 6

5kx = 7kx - 6

 

Then subtract 7kx on both sides

5kx - 7kx = 7kx - 6 - 7kx  

-2kx = -6  

 

Now divide by -2k on both sides

-2kx/-2k = -6/-2k

x = -6/-2k

Simplify

x = 3/k  

These are algebriac equations that you keep doing. Maybe try practicing the simpiler algebriac equations then slowely do more complicated ones. Just letting you know.

A long-term period of economic recession that leads to a low GDP and very high unemployment is a(n)
Liula [17]

Answer:

The answer is C. Depression.

Step-by-step explanation:

Depression is defined as a severe and prolonged recession. Declining economic activity is characterized by falling output and employment levels. Generally, when an economy continues to suffer recession for two or more quarters, it is called depression.

The level of productivity in an economy falls significantly during a depression. Both the GDP (gross domestic product) and GNP (gross national product) show a negative growth along with greater business failures and unemployment. Depressions are relatively less frequent than milder recessions, and tend to be accompanied by high unemployment and low inflation.

On a coordinate plane, triangles R S T and L M N are shown. Triangle R S T has points (5, 5), (2, 1), and (1, 3). Triangle L M N
ivolga24 [154]

Answer:

LMN has a larger area

Step-by-step explanation:

Given

RST

R =(5,5)

S= (2,1)

T = (1,3)

LMN

L = (0,-1)

M= (2,-4)

N= (-2,-3)

Required

Compare both areas

The area of triangle is:

Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3|

For RST, we have:

Area = \frac{1}{2}|5*1 - 2*5 + 2*3 - 1*1 + 1*5 - 5*3|

Area = \frac{1}{2}|-10|

Remove absolute signs

Area = \frac{1}{2}*10

Area = 10

For LMN, we have:

Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3|

Area = \frac{1}{2}|0*-4-2*-1+2*-3--2*-4--2*-1-0*-3|

Area = \frac{1}{2}|-14|

Remove absolute signs

Area = \frac{1}{2}*14

Area = 7

<em>By comparing both areas, we can conclude that LMN has a larger area</em>
