2x + a = 2x -3 in the equation above, a is a constant l. for what value of a does the equation have no solutions?

1 answer:

4 0

A=-3 and i think any value of 'a' makes those equation infinite solution because expression has same variable both side.

Which of the following is a like radical to 3 sqrt 7x?

san4es73 [151]

Answer:

Options A and B

i.e., A. 4(3 $\sqrt{7x}$ ) and B. $\sqrt{7x}$

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, $\frac{1}{2} x$ , 7.3x are like terms.

$xy^{2} , -9xy^{2} , 13y^{2} x$ are some more examples of like terms.

Similarly, like radicals are:

$\sqrt{2} , -5\sqrt{2} , 1.1\sqrt{2}$ etc.

Hence, from the given options, like radicals to $3\sqrt{7x}$ are:

A. $4(3\sqrt{7x} )$ and B. $\sqrt{7x}$

Find the distance between two points C(-6,5) and D(-3,1)

gladu [14]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have:

$C(-6,\ 5)\to x_1=-6,\ y_1=5\\D(-3,\ 1)\to x_2=-3,\ y_2=1$

substitute:

$d=\sqrt{(-3-(-6))^2+(1-5)^2}=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

Answer: 5 units.
