Answer:

would be c

Step-by-step explanation:

count how much over then goes how much up until it reaches the point that is marked, so it would be (x,y) so (3,2) x is verticle axis and y is horizontal axis

Answer:

c. (3, 2)

Step-by-step explanation:

Equating the values of y :

-x + 5 = x - 1
x + x = 5 + 1
2x = 6
<u>x = 3</u> [x-coordinate of the solution]

Finding y by substituting x in one of the equations :

y = x - 1
y = 3 - 1
<u>y = 2</u> [y-coordinate of the solution]

Solving :

Solution = (x, y)
Solution = (3, 2)

Cos^-1(-x)=-Cos^-1x for -1<x<1 TRUE OR FALSE?

VMariaS [17]

We are given

$cos^{-1}(-x)=-cos^{-1}(x)$

Firstly, we will simplify left side

and we will check whether it is equal to right side

Left side:

Let's assume y left side expression

$y=cos^{-1}(-x)$

now, we can take cos on both sides

$cos(y)=cos(cos^{-1}(-x))$

we can simplify it

$cos(y)=-x$

Right side:

Let's assume y left side expression

$y=-cos^{-1}(x)$

Multiply both sides by -1

$-y=cos^{-1}(x)$

now, we can take cos on both sides

$cos(-y)=cos(cos^{-1}(x))$

we can simplify it

$cos(-y)=x$

$cos(y)=x$

we can see that

both sides cos(y) value is different

so, this is FALSE.........Answer
