How many solutions do these equations have y= 3x+4 y+6=3x

Nataly [62]

Answer:

Step-by-step explanation:

hello :

the system is : y= 3x+4....(*)

y+6=3x....(**)

by (**) : y = 3x - 6

so : y= 3x+4

y= 3x - 6

means : 3x+4 = 3x - 6

4= -6.......(false)

conclusion : no reals solutions

Ivenika [448]

4(610-15)+0.4
first you have to distribute the 4 to what is inside the paranthesis
(4×610)-(4×15)+0.4
2440-60+0.4=2380.4

Perform the following operations and write the answers in radical form.

strojnjashka [21]

Given:

Part A: $\sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}$

Part B: $3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}$

To find:

The simplified radical form.

Solution:

Part A: $\sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}$

$\sqrt{98}=\sqrt{7^2 \times 2} =7 \sqrt{2}$

$\sqrt{18}=\sqrt{3^2 \times 2} =3 \sqrt{2}$

Substitute these in the given expression.

$\sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}=\sqrt{7}+\sqrt{3}+7\sqrt{ 2}-3\sqrt{ 2}$

Add or subtract the coefficient of same radical.

$=\sqrt{7}+\sqrt{3}+(7-3)\sqrt{ 2}$

$=\sqrt{7}+\sqrt{3}+4\sqrt{ 2}$

Part B: $3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}$

$2 \sqrt{121}=2\sqrt{11^2}$

$=2\times 11$

= 22

$3 \sqrt{90}=3\sqrt{3^2 \times 10}$

$=3\times 3 \sqrt{10}$

$=9 \sqrt{10}$

Substitute these in the given expression.

$3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}=3 \sqrt{5}-3 \sqrt{11}+22-9 \sqrt{10}$
