Answer:

So you have the multiplication and substitution right. It's just the subtraction.

Step-by-step explanation:

Now, the equation was y = 4x - 2

In the first one x = -3

So it will be 4(-3) - 2

Note: Anytime you see a bracket it means multiplication.

4× -3 = -12 and

-12 - 2 = -14

This is because a negative number minus another number is always negative.

And when dealing with negative numbers you add them but you negate the answer.

For example;

The second one will be -8 - 2

And 8 + 2 = 10

But since the numbers are negative we just negate the 10 making it - 10.

I hope this helps

Point V is on line segment UW. Given UW=13 and VW = 11, determine the length of UV
jekas [21]

Answer:

UV = 2

Step-by-step explanation:

Given

UW = 13

VW = 11

Required

Determine UV

From the question, we have

UW = UV + VW

Make UV the subject of formula

UV = UW - VW

Substitute 11 and 13 for VW and UW, respectively

UV = 13 - 11

UV = 2

What is the domain of the relation y = arccscx?
Stella [2.4K]

Answer:

y=arc\csc x

Step-by-step explanation:

The given function is y=arc\csc x.

The domain refers to all values of x for which this function is defined.

Recall that: the domain of y=arc \sin (x) is -1\le x\le1

And we know y=arc\csc x is the reciprocal of y=arc \sin (x).

Therefore the complement of the domain of y=arc \sin (x) which is (-\infty,-1]\cup [1,+\infty) is the domain of y=arc\csc x

Round 27346 to 2 significant figures i need a step by step expansion
belka [17]

Answer:

27000

Step-by-step explanation:

We want to round 27346 to 2 significant figures.

Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.

Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.

Is that right? <br><br> Please help
kondaur [170]

Answer:

yes x = 16

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is

133 = x + 117 ( subtract 117 from both sides )

16 = x
