Help me pls

I think you can find it graphically by points through a table you create like:

let x = 0, and find the value of y

for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like

to be more accurate you can find 3 pionts and start graphing them

these two equations are straight lines and they will intersect in a point

4x + 7 = 23slove this

Juli2301 [7.4K]

Given:

4x + 7 = 23

Let's solve for x.

First Step:

Subtract 7 from both sides

4x + 7 - 7 = 23 - 7

4x = 16

Next Step:

DIvide both sides by 4

$\begin{gathered} \frac{4x}{4}=\frac{16}{4} \\ \\ x\text{ = 4} \end{gathered}$

ANSWER:

x = 4

HELPP!!<br> Select the correct answer.<br> What is the value of arcsin ?

Schach [20]

For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.

We must find the $arcsin (\frac {\sqrt {2}} {2})$ . Then, we look for the angle whose sine is $\frac {\sqrt {2}} {2}$ .

We have to, by definition:

$Sin (45) = \frac {\sqrt {2}} {2}$

So, we have to:

$arcsin (\frac {\sqrt {2}} {2}) = 45$
