OK either the equation is \sqrt{} 2x+4 - \sqrt{x} -2 =0 or \sqrt{} 2x+4 = \sqrt{x} -2  Either way it ends up the same because if it is the first equation, I would move the \sqrt{x} - 2 to the other side of the equation.  It would become \sqrt{x} + 2.

For my example, I am going with \sqrt{} 2x+4 = \sqrt{x} -2 
Square both sides
2x+4=(x+2)^{2}
Then use FOIL to solve the right side
2x+4=x^{2} +2x+2x+4
Then combine like terms
2x+4=x^{2} +4x+4
Set it equal to 0 and combine like terms
0= x^{2} -2x
0=x(x-2)
So x=0 and x=2
If it was the other was it would be x=-2

Hope that helps.

What is the length of side AC
natulia [17]

Answer:

7 Units.

Step-by-step explanation:

First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.

A line passes through (10,2) and (14,-22). Write the equation of the line in standard form.
jarptica [38.1K]

Answer:

The equation of the line in standard form is:

6x + y = 62

Step-by-step explanation:

Given the points

  • (10,2)
  • (14,-22)

Determining the slope between (10, 2) and (14, -22)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(10,\:2\right),\:\left(x_2,\:y_2\right)=\left(14,\:-22\right)

m=\frac{-22-2}{14-10}

m=-6

The point-slope form of the line equation is  

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

substituting the values m = -6 and the point (10, 2) in the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

y - 2 = -6(x - 10)

y - 2 = -6x +60

adding 2 to both sides

y-2+2 = -6x + 60 + 2

y = -6x +  62

We can write the equation in the standard form such as

Ax + By = C

Thus,

y = -6x +  62

adding -6x to both sides

6x + y = -6x + 62 + -6x

6x + y = 62

Therefore, the equation of the line in standard form is:

6x + y = 62

you need 2b cups of flour for making b loaves of bread.You have 8 cups of flour.Do you have enough for 5 loaves of bread?Explain
amm1812

No, you do not have enough flour. To solve, you would need to substitute 5 for b, and 2 * 5=10. Since you only have 8 cups of flour, you do not have enough.
