Answer:

Step-by-step explanation:

You can find slope using the slope equation : $\frac{y2-y1}{x2-x1}$

Plug in the two points : $\frac{4-(-18)}{4-(-7)}$

Calculate by adding the numbers: $\frac{22}{11}$

Reduce the fraction : 2

The slope is 2

Rewrite using the distributive property and GCF 16 + 40

Artist 52 [7]

The GCF of 16 and 40 is 8.

16/8 = 2

40/8 = 5

We can rewrite this using the distribute property like so:

Using the distributive property:

16 + 40

16 + 40 = 56

We can also add inside the parentheses and multiply and we'll get the same answer.

Graph the inequality on the numberline and then write it in interval notation. 4-3y<-8

pogonyaev

First, let's simplify the inequality

$\begin{gathered} \frac{4}{3}y$

The graph looks like this:

Notice that the white dot is placed above the -6, it is important to include it like that.

Now, as an interval:

$\begin{gathered} y$

The picture is the answer i forgot it last time

C is your answer

because (4, -6) is true, and it lies on both lines, which makes both equations true

hope this helps

Which equation is related to √x+10-1=x ? The square root is over the x+10

Sergio [31]

Answer:

(b) x + 10 = x^2 + 2x + 1

Step-by-step explanation:

The equation can be transformed to one without the radical by isolating the radical and squaring both sides.

$\sqrt{x+10}-1=x\qquad\text{given}\\\\\sqrt{x+10}=x+1\qquad\text{add 1 to both sides}\\\\x+10=(x+1)^2\qquad\text{square both sides}\\\\\boxed{x+10=x^2+2x+1}\qquad\text{eliminate parentheses}$

<em>Additional comment</em>

In typeset formulas, radicals, fraction bars, and superscript formatting serve to group expressions. In plain text, the only available grouping symbol is parentheses.

$\sqrt{x+1}}\ \Rightarrow$ √(x+1)
