Solve the equation square root of x plus three plus four equals five for the variable. Show each step of your solution process

alekssr [168]

Answer:

$x=-2$

Step-by-step explanation:

The given expression is

$\sqrt{x+3}+4=5$

We group the constant terms on the right hand side to obtain;

$\sqrt{x+3}=5-4$

$\Rightarrow \sqrt{x+3}=1$

We square both sides of the equation to remove the square root.

$\Rightarrow (\sqrt{x+3})^2=1^2$

$x+3=1$

This will simplify to;

$x=1-3$

$x=-2$

Given 2 points (-2,6) and (5,-8) what is the slope, distance, and midpoint

Anastasy [175]

(-2,6) (5,-8)

slope = (y2 - y1) / (x2 - x1)
slope = (-8 - 6) / (5 - (-2) = -14/7 = -2 <==

midpoint = (x1 + x2)/2 , (y1 + y2)/2
m = (-2 + 5)/2 , (6 - 8)/2
m = (3/2, -1) <===

distance = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
d = sqrt ((5 - (-2)^2 + (-8 - 6)^2)
d = sqrt ((5 + 2)^2 + (-14^2))
d = sqrt (7^2 + 14^2)
d = sqrt (49 + 196)
d = sqrt 245
d = 15.65 <==

Drag the blue point to a place on the number line

sergejj [24]

Answer:

The number line is shown below.

Step-by-step explanation:

We need to represent number that is less than 3 on a number line.

Let x be numbers.

So, $x$ .

Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.

The number line is shown below.
