Solve the system.... 2y+8x+58 and y-5x=11

Answers

Answer 1

Answer:

x=2, y=21

Step-by-step explanation:

there are two methods: substiution and elimation. I will be doing subtistution in this soultion:

first isolate y in either equation, it would be easier to do it in the second one.

y= 11+5x

Then, subtitute that into the first equation

2(11+5x)+8x=58 (it says 2y+8x+58 but I assume you mean 2y+8x=58?)

22+10x+8x=58

18x = 36

x=2

substitute that back into y = 11+5x, to get y=11+10 = 21

To find:

Factorized form of given expression.

Solution:

We have,

[tex]30x^3+22x^2+4[/tex]

[tex]=2x(15x^2+11x+2)[/tex]

Splitting the middle term, we get

[tex]=2x(15x^2+6x+5x+2)[/tex]

[tex]=2x(3x(5x+2)+1(5x+2))[/tex]

[tex]=2x(3x+1)(5x+2)[/tex]

Therefore, the complete factorized form of given expression is [tex]2x(3x+1)(5x+2)[/tex].

find the equation of the line that is parallel y= 2x+10 and passes through the point (6,-4)

Answers

Answer:

The equation of the parallel line to the given line

y = 2 x - 16

Step-by-step explanation:

Step(i):-

Given equation of the straight line y = 2 x +10

                                             2x - y + 10 =0

The equation of the parallel line to the given line is

           a x + by + k=0

The equation of the parallel line to the given line is

           2x - y + k=0

Step(ii):-

Given point ( 6,-4)

The equation of the parallel line to the given line is

           2x - y + k=0

This line passing through the point ( 6,-4)

           2(6) - (-4)+ k=0

          12 + 4 +k =0

           16 + k=0

                k = -16

Final answer:-

The equation of the parallel line to the given line

y = 2 x - 16

what is the hight?
and area?

Answers

Answer:

Step-by-step explanation:

As we know that,

Area of isosceles triangle= 1/2 *b*h

we have a=10  and  other side = hypotenuse=b=13 cm

Now e have formula to find h,

h=[tex]\sqrt{b^{2} -a^{2}/4}[/tex]

now putt the values ,

we get,

h=[tex]\sqrt{169-100/4}[/tex]

h=[tex]\sqrt{576/4}[/tex]

h=12 cm  height of isosceles triangle ,

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than twice the number
sent. How many were sent and how many were received each day?

Answers

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111      Eqn 1

y = 2x + 3     Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75
