Determine the intercepts of the line

x intercept : ?,?
y intercept: ?,?

Variation can be direct, inverse or joint.

The perimeter is 243 cm

Represent perimeter with P and side lengths with L.

So, we have:

[tex]\mathbf{P\ \alpha\ L}[/tex]

Express as an equation

[tex]\mathbf{P = kL}[/tex]

Where k is the constant of variation.

Make k the subject

[tex]\mathbf{k = \frac PL}[/tex]

So, we have:

[tex]\mathbf{\frac{P_1}{L_1} = \frac{P_2}{L_2}}[/tex]

Make P2 the subject

[tex]\mathbf{P_2 = L_2 \times \frac{P_1}{L_1} }[/tex]

Substitute the given parameters

[tex]\mathbf{P_2 = 81 \times \frac{153}{51} }[/tex]

[tex]\mathbf{P_2 = 81 \times 3 }[/tex]

[tex]\mathbf{P_2 = 243}[/tex]

Hence, the perimeter is 243 cm

Answer:

Non terminating recurring decimals

Step-by-step explanation:

Decimals can be categorised into two groups: Terminating and non-terminating. Terminating decimals are rational, and non terminating can be further divided into: Non terminating Recurring (which are rational) and Non terminating Non recurring (which are irrational).

Answer:

D) 70 degrees

Step-by-step explanation:

A triangle angle's has a total of 180 degrees

180 - 40 = 140

140/2 = 70    (the other 2 angles are equvilent angles)

Brainly plz :)

Answer:

answer below

Step-by-step explanation:

every triangle has angle that, added together, equal 180 degrees.

if the given angle is 40 and the red lines tell you the sides are equal in length (both lines have only one red line so they are the same.), calculate the angles. (hint they are both the same amount of degrees.)

My process:

180-40=140

?+?=140

70+70=140

solution= 140 degrees

Answer:

.98 L / b   * .4 b   = .392 L         amount contained in sample

.99 L / b  * .25 b  = .248 L        this was rounded from .2475

1.00 L / b * .3 b   = .30 L

1.01 L / b * .05 b =   .05 L

---------------------------------------

3.98 L / 4 b * 1.0 b     = .99 L

Actual measurements might be 40 bottles at .98 L/b, 25 bottles at .99 etc

Then the total liters would be divided by the total number of bottles

the slope is -1/3 and since the slope is negative, the line goes the opposite way and you start at (3,0)

Answer:

domain - (-infinity,infinity)

range - (-infinity, 2]

axis of sym - x=-1

y int - (0,-1)

at what value (row 1) - (-1,2)

Step-by-step explanation:

domain is side to side, it never ends bc of the arrows

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)

the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up

Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?

Solution :

Cost price of oranges = rs.310

As we know that each oranges cost rs.12

So, selling price of oranges is 30 × 12 = rs.360

Now, finding profit or loss

Profit = Selling Price - Cost Price

Profit = rs.360 - rs.310

Profit = rs.50

Answer:

Given equation is (8/y) = 2/(y-2) +1

=> (8/y)- 2/(y-2) = 1

=> [8(y-2)-2y]/(y-2)y = 1

=> (8y-16-2y)/(y²-2y) = 1

=> (6y-16)/(y²-2y) = 1

=> y²-2y = 6y-16

=> y²-2y -6y+16 = 0

=> y²-8y+16 = 0

The standard form is y²-8y+16 = 0.

Answer:

-6

Step-by-step explanation:

8/y = 2/y - 2 + 1

8/y = 2/y - 1

8 = 2 - y

6 = -y

y = -6

Answers:

Domain is  [tex]0 \le d \le 100[/tex]

Range is  [tex]0 \le F(d) \le 150[/tex]

==============================================

Explanation:

The most money made from selling drinks is $150. Divide this over the cost per drink to get 150/(1.50) = 100; indicating that at most 100 drinks are sold per day. This is the largest that d can get because d represents the number of drinks sold.

The smallest d can get is d = 0 to mean that no drinks are sold.

In short: d is between 0 and 100, including both endpoints. We write [tex]0 \le d \le 100[/tex] to indicate this. This is the domain because the domain represents all the possible inputs allowed.

---------------------------------------------------

The range is the set of allowed outputs.

If we plugged in d = 0, then you would find F(d) = 0 as well. If you don't sell any drinks, then you earn $0. This is the smallest item in the range.

On the other side of things, the largest item in the range is 150 because this value was given to us. It's the upper limit or ceiling value of how much money is made from drinks. You can also find this by plugging d = 100, the largest domain value, into the function to get F(d) = 150.

Therefore the range is [tex]0 \le F(d) \le 150[/tex] to indicate that F(d) is between 0 and 150 inclusive of both endpoints.

Answer:  the gcf of 72 and 108 is 36!

The corresponding roots of the quadratic equations are given.

Quadratic expressions are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

1. x² = 49

Find the square root.

x = ±√49 = ±7

2. x² - 27 = 0

x² = 27 = 9 × 3

x = √27 = √(9×3) = √9 × √3 = ±3√3

3. 3x² - 36 = 0

3x² = 36

Divide 3 on both sides.

x² = 12

x = √12 = √(4 × 3) = ±2√3

4. 9x² = 0

x = 0

5. 5x² - 15 = 0

5x² = 15

x² = 3

x = ±√3

6. 2x² - 144 = 0

2x² = 144

x² = 72

x = √72 = √(36 × 2) = ±6√2

7. (x + 3)² = 9

x + 3 = √9

x + 3 = ±3

x = 3 - 3 = 0 and x = -3 - 3 = -6

8. 4x² - 100 = 0

4x² = 100

x² = 25

x = ±√5

9. 5x² = 40

x² = 8

x = √8 = √(4 × 2) = ±2√2

10. 3x² - 12 = 0

3x² = 12

x² = 4

x = ±2

11. (x - 5)² = 121

x - 5 = √121

x - 5 = ±11

x = 11 + 5 = 16 or x = -11 + 5 = -6

Hence the solutions are found.
