Systems of equation substitution 2x+4y=24 x=4y

Mathematics
1 answer:
antoniya [11.8K]3 years ago
5 0

Answer:

(x, y) = (8, 2)

Step-by-step explanation:

substitute x = 4y into the other equation

2(4y) + 4y = 24

8y + 4y = 24

12y = 24 ( divide both sides by 12 )

y = 2

substitute y = 2 into x = 4y

x = 4 × 2 = 8

solution is (8, 2 )

How do i solve this inequality? -2|3m|+3<-51
9966 [12]

Answer:

m >9  or      m < -9

Step-by-step explanation:

-2|3m|+3<-51

Subtract 3 from each side

-2|3m|+3-3<-51-3

-2|3m|<-54

Divide each side by -2, remembering to flip the inequality

-2|3m|/ -2>-54/-2

|3m|> 27

To get rid of the absolute values, we separate into two inequalities, one as written and one negative, remembering to flip the inequality

3m >27  or     3m <-27

Divide by 3 on each side

3m/3 >27/3  or     3m/3 <-27/3

m >9  or      m < -9

In circle V, r = 14ft.
Bad White [126]

For this case we have that by definition, the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

According to the data of the statement we have that the circle has a radius of 14 \ ft

Substituting in the formula we have:

A = \pi * (14) ^ 2\\A = \pi * 196\\A = 196 \pi

So, the area of the circle is 196 \pi feet squared

Option D
