Answers

Answer 1

Step-by-step explanation:

The given equations are :

y = x + 3 .....(1)

y = 2x – 5 ......(2)

The table for equation (1) is :

x = 0, 1, 2, 8

y = 3, 4, 5, 11

The table for equation (2) is :

x = 0, 1 , 2, 8

y = -5, -3, -1, 11

From the graph we can see that,

The x-value is = 8

The y-value = 11

The solution is = (8,11).

Answer 2

The x-value is = 8, the y-value = 11 and the solution is = (8,11)

How to determine the equation solutions?

The equations are given as:

y = x + 3

y = 2x - 5

Next, we plot the graph of the equations

From the graph of the equations, we have:

(x,y) = (8, 11)

Hence, the x-value is = 8 and the y-value = 11

So, the solution is = (8,11)

Answers

Answer:

Step-by-step explanation:

It is given that 1 gallon of paint covers about 450 square feet.
To calculate how many square feet will 1.5 gallon of paint cover, we have to multiply 450 by 1.5.
1.5 gallons of paint cover = 450 × 1.5 = 675 square feet.

Find the value of x. Give reasons to justify your solution-

Answers

Answer:

x = 34

Step-by-step explanation:

∠ PSR and ∠ TSU are vertical angles and congruent, then

∠ PSR = 4x, thus ∠ PSQ = x

The exterior angle of a triangle is equal to the 2 opposite interior angles.

∠ SQR is an exterior angle of Δ PQS , thus

x + x = 68

2x = 68 ( divide both sides by 2 )

x = 34

Answer:

X = 34°

Step-by-step explanation:

In order to solve this question we will need to know the following, when two lines intersect the opposite angles at that point are equal to each other, that the sum of all angles of a triangle is 180 degrees, and that the angle of a straight line is equal to 180 degrees.

Frist we will have to notice that ∠TSU is equal to ∠PSR, because they are opposite to each other (If you would like to understand this more you can research on a topic call "vertical angels"). Now it is important to understand the following.

∠PSR  = ∠PSQ + QSR

Since ∠PSR = ∠TSU = 4x, ∠QSR = 3x ⇒

⇒ ∠PSR  = ∠PSQ + QSR

   4x = ∠PSQ + 3x

   4x - 3x = ∠PSQ

   x = ∠PSQ

Now, since the sum of all angles in a triangle is equal to 180 we can now say the following:

∠QPS + ∠PSQ + ∠PQS = 180°

In order to find out what PQS is equal to we need to use our knowledge about the angel of a strait line (the angel of a strait line is equal to 180°).

So now we can say the following:

180° = ∠PQS + SQR

∠PQS = 180° - ∠SQR

Since we know that ∠SQR = 68° ⇒

⇒∠PQS = 180° - ∠SQR

  ∠PQS = 180° - 68°

  ∠PQS = 112°

Since ∠QPS = x, PSQ = x, and ∠PQS = 112° ⇒

⇒ ∠QPS + ∠PSQ + ∠PQS = 180°

   x + x + 112° = 180°

  2x = 180° - 112°

  2x = 68°

  x = 34°

Answers

Answer:

Depreciation and Written Down Value for first 5 years of purchase is explained.

Step-by-step explanation:

The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.

Declining Method

Year 1

$18,000 * 20% = $3,600 Depreciation

$18,000 - $3,600 = $14,400 Written Down Value WDV

Year 2

$14,400 * 20% = $2,880 Depreciation

$14,400 - $2,880 = $11,520 WDV

Year 3

$11,520 * 20% = $2,304 Depreciation

$11,520 - $2,304 = $9,216 WDV

Year 4

$9,216 * 20% = $1,843 Depreciation

$9,216 - $1,843 = $7,373 WDV

Year 5

$7,373 * 20% = $1,475 Depreciation

$7,373 - $1,475 = 5,898 WDV

HELP!!! PLEASE TELL ME WHICH GRAPH GOES WHERE!!! DON'T IGNORE PLEASE!!!

Answers

So y=mx+b is still prevalent here even if it's an inequality. Meaning your slope AND y-intercept can help you. Even if it's in ax+by=c you can easily get the y alone into slope-intercept.

y<_3x+5 for example. For one, it is y is less than or equal to 3x+5. So the line shouldn't be dotted. So that leaves us with the two far-right graphs to look at. 5 is our y-intercept in the equation. So look at our graph and see which one has the line passing through 5. They both do. Okay, well we can still use our sign, it shows that y is LESS than 3x+5. So the shaded blue part should be on the right. If it was the other way around it would be the left. So our graph should be the far right for this equation.

Hope this helps... I know it's kind of messy. If you need any more help let me know. But I hope I outlined what to look for.

estimate √9.7+3.88×6.21

Answers

9514 1404 393

Answer:

  a little more than 27

Step-by-step explanation:

Estimates are generally made by approximating the numbers using 1 or 2 significant digits. The idea is to do as much mental arithmetic as possible, not involving a calculator. Here, the estimate can be based on rounding the values like this:

  √9.7 +3.88 × 6.21 ≈ √9 +4 × 6 = 3 +24 = 27 . . . estimated expression value

__

Another aspect of estimating is determining the approximate error involved.

We know that √9.7 will be more than √9 = 3, and less than √10 ≈ 3.16*. Its real value may be about 3.1.

3.88 is less than 4 by 0.12, or 3%. 6.21 is greater than 6 by .21, or 3.5%. So, the estimated product of 24 will be on the order of -3% +3.5% = 0.5% too low. Of course 1% of 24 is 0.24, so 1/2% will be about 0.12. Now, we are able to estimate that our estimate is about 0.2 units too low. (The actual value of the expression is an irrational number that rounds to about 27.2093.)

_____

* The value of 3.16 for √10 is not so hard to remember, because it is just slightly more than π ≈ 3.14.

__

Additional comment

Small percentages can usually be added and subtracted without introducing too much additional error. (The smaller the percentages, the less additional error is introduced.) Here, the error in our estimated product can be more accurately determined by computing ...

  (1 -3%)(1 +3.5%) = 1 +0.5% -0.105% = 1 +0.395% . . . . . . (not 1 +0.5%)

That is, our product's actual value is 24.0948, not 24.12.
