Answer:
y=2/3x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=2/3(x-(-6))
y+6=2/3(x+6)
y=2/3x+12/3-6
y=2/3x+4-6
y=2/3x-2

If 13% is lost by selling goods for Rs 1475, what would be the loss or gain if the goods are sold for Rs 1615?
Given:
Loss percent is 13%.
Selling price = 1475
To find:
The loss or gain if the goods are sold for Rs.1615?
Solution:
Let x be the cost price of goods.
Loss percent is 13% and selling price is 1475.
[tex]1475=x-\dfrac{13}{100}x[/tex]
[tex]1475=x-0.13x[/tex]
[tex]1475=0.87x[/tex]
[tex]\dfrac{1475}{0.87}=x[/tex]
[tex]1695.4023=x[/tex]
[tex]x\approx 1695.40[/tex]
The cost price of goods is 1695.40.
We need to find the loss or gain if the goods are sold for Rs.1615.
Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.
[tex]Loss=CP-SP[/tex]
[tex]Loss=1695.40-1615[/tex]
[tex]Loss=80.40[/tex]
The loss percent is
[tex]Loss\%=\dfrac{Loss}{C.P}\times 100[/tex]
[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]
[tex]Loss\%\approx 4.74\%[/tex]
Therefore, the loss is 80.40 and the loss percent is about 4.74%.

Write the polynomial in standard form. Then identify the leading coefficient and the constant. Classify the polynomial by the degree and number of terms.
4+5x^(2)-x
Answers:
Standard Form: 5x^2 - x + 4Leading coefficient: 5Constant: 4Degree: 2Number of terms: 3=====================================================
Explanation:
The term with the largest exponent will go first, followed by the next largest exponent, and so on. This will get the polynomial into standard form. So 4+5x^2-x turns into 5x^2-x+4. You can think of this as 5x^2-x^1+4x^0. Note the exponents counting down: 2,1,0.
Each term is separated by a plus or a minus. We can think of 5x^2-x+4 as 5x^2+(-x)+4
The leading term is the first term 5x^2. It has the coefficient of 5, so the leading coefficient of the overall polynomial is 5.
The constant is the term without any variables attached to it. So the constant is 4. As the name implies, the constant doesn't change no matter what x changes to. In contrast, the 5x^2 term does change as x changes.
The degree is the largest exponent, so in this case it would be 2. After you get the polynomial into standard form, it's the first exponent on the left.
As mentioned earlier, each term is separated by a plus or a minus. So we have three terms here. We consider this a trinomial since "tri" means "three". More specifically, this is a quadratic trinomial. Any quadratic will have the largest exponent being 2.
what is the y-intercept of 2x^2-8x+21
Answer:
the y-intercept is (0,21)
Answer:
(0,21)
Step-by-step explanation:
If you set x to 0, you can solve for the y-intercept. Plugging in 0 in this equation will give you 21. Therefore, the y-intercept is at (0,21).
Perry finished a 100-meter race in 7/8 of a minute. The winner of the race used 14/15 of Perry's time to finish the race. How much time did the winner use to finish the race?
Answer:
49 seconds
Step-by-step explanation:
The time perry used is 7/8 of a minute
a minute equals to 60 seconds
so the time perry used is 7/8 x 60 = 52.5 seconds
The winner used 14/15 of 52.5 seconds (perrys time)
so 14/15 x 52.5 = 49 seconds

Using the 28/36 ratio, determine the maximum allowable recurring debt for someone with a monthly income of $3,200. a. $256 b. $512 c. $640 d. $896
Answer:
a. $256
Step-by-step explanation:
The computation of the maximum allowable recurring debt is shown below:
Given ratio = 28:36
And the monthly income is $3,200
So the maximum expense on housing = 28% of $3,200 = $896
And, the maximum expense on total debt = 36% of $3,200 = $1,152
Now the maximum alloweable recurring debt is
= $1,152 - $896
= $256

Ali and billy ran around a race track. How many more metres did Ali ran than billy in one lap? (Find perimeter)
Answer:
Ali ran 25.13 m more than bily
Step-by-step explanation:
From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.
Thus;
Diameter of inner semi circle = 20 m
Diameter of outer semi circle = 20 + 4 + 4 = 28 m
Perimeter of inner semi circle = πD/2 = 10π
Perimeter of outer semi circle = πD/2 = 14π
Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m
Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m
Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m

What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?
Answer:
y = 11x + 76Step-by-step explanation:
The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:
y - y₀ = a(x - x₀)
a = 11, x₀ = -7, y₀ = -1
So:
y - (-1) = 11(x - (-7))
y = 11x + 77 - 1
y = 11x + 76

Step-by-step explanation:
The length of a rectangle is 3 m longer than its width. If the perimeter of the rectangle is 26 m , find its area.
Answer:
40 m²
Step-by-step explanation:
First, find the perimeter. Using the perimeter formula, p = 2l + 2w, solve for the side lengths of the length and width.
Let w represent the width. The length can be represented by w + 3, since the length is 3 m longer than the width.
Plug in 26 as the perimeter, and plug in w and w + 3 for the width and length:
p = 2l + 2w
26 = 2(w + 3) + 2w
Simplify and solve for w:
26 = 2w + 6 + 2w
26 = 4w + 6
20 = 4w
5 = w
Find the length by adding 3 to this:
5 + 3
= 8
Now, find the area using the area formula, A = lw
Plug in the length and width:
A = lw
A = 8(5)
A = 40
So, the area of the rectangle is 40 m²
