What is the answer to 4x=-12

a post on a classifieds website Craigslist advertised a mountain bike selling for $1,164 less than it's retail price. if this is

earnstyle [38]

From the information given 40% represents the savings and is 1, 164 dollars

Therefore 100% represents the full retail price.

We first find out what 1% represents.

40% = 1,164

1% = x (where x is the amount in dollars equivalent to 1%)

We then simplify the equation

x × 40% = 1,164 × 1%

40 x = 1,164

x = 1,164 / 40 → x = 29.1

So 1% is equivalent to 29.1 dollars. How about 100%?

100% will be 100 × 29.1 = 2,910

Therefore the full retail price is $ 2,910

What is the equation of this line? y=12x−3 y=−12x−3 y=−2x−3 y=2x−3 Number graph ranging from negative 5 to 5 on both the x and y

Tems11 [23]

We are given that

A line passes through two points as

(0,-3) and (4,-1)

$(x_1,y_1)=(0,-3)$

$x_1=0,y_1=-3$

$(x_2,y_2)=(4,-1)$

$x_2=4,y_2=-1$

Firstly, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{-1+3}{4-0}$

$m=\frac{2}{4}$

$m=\frac{1}{2}$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y+3=\frac{1}{2} (x-0)$

$y+3=\frac{1}{2}x$

$y=\frac{1}{2}x-3$

so, the equation of line is

$y=\frac{1}{2}x-3$ ...............Answer

Khan sold his cycle at loss of 8%.had He sold it for 240 more he would have gained 12%

denpristay [2]

Khan sold his cycle at loss of 8%.had He sold it for 240 more he would have gained 12%. Then cost price is $ 1200 and selling price is $ 1104

<h3><u>Solution:</u></h3>

Assume the cost price be "a"

So the selling price of cycle = a - 8% of a

$\text { selling price }=a-\frac{8 a}{100}=\frac{23 a}{25}$

Now according to given, had He sold it for 240 more he would have gained 12%

Selling price + 240 = cost price + 12% profit

$\frac{23a}{25} + 240 = a + \frac{12a}{100}$

$\frac{23a + 6000}{25} = \frac{100a + 12a}{100}\\\\92a + 24000 = 112a\\\\20a = 24000\\\\a = 1200$

So the cost price is $ 1200

Now the selling price = $\frac{23a}{25} = \frac{23 \times 1200}{25} = 1104$

So the selling price is $ 1104

What is the exact volume of this cone?

Studentka2010 [4]

Answer:

(b) 80/3π in³

Step-by-step explanation:

The volume of a circular cone is given by ...

V = 1/3πr²h . . where r is the radius (half the diameter) and h is the height

Your cone has r = 4 inches and h = 5 inches, so its volume is ...

V = (1/3)π(4 in)²(5 in) = 80/3π in³

The volume of the cone is exactly (80/3)π cubic inches.
