Find an equation of the line with the slope m= 3 that passes through the point (2,2). Write the equation in the form Ax+By = C.

Step-by-step explanation:

Given,

RSTU is a parallelogram,

so, we need to find the value of x,

let's find it,

2x+15 = x+15 (opposite side of parallelogram are equal and parallel)

2x - x = 15-15

x=0

Therefore, the value of x is 0.

If you have doubt. then let's clear it by putting the value of x.

so, 2×0+15 = 0+15

15=15 {as already said that the sides are equal}

proved..

so, the value of x is 0.

Hope it helps.....

Answer:

x=0

Step-by-step explanation:

Assuming the two sides are equal length

2x+15 =x+15

Subtract 15 from each side

2x =x

Subtract x from each side

2x-x = x-x

x=0

Step-by-step explanation:

f(x)=x² +3x+2

Set the function equal to zero

0=x² +3x+2

Factor

What 2 numbers multiply to 2 and add to 3

2*1 = 2

2+1 = 3

0 = ( x+2) (x+1)

Using the zero product property

x+2 =0   x+1 =0

x=-2       x=-1

Answer:

B) 30

Step-by-step explanation:

Since ABCD is a parallelogram the diagonals bisect each others in their midpoint.

Wich means that BE = ED

● BE = ED

● (2/3)x = x-10

Substract x from both sides

● (2/3)x -x = x-10 - x

● (2/3) x - x = -10

Multiply x by 3 then ubstracr it from 2x

● (2x-3x)/3 = -10

● -x/3 = -10

Multiply both sides by -3

● (-x/3)×(-3) = -10 ×(-3)

● x = 30

Step-by-step explanation:

Video Game

20% off means you pay 80%

80 dollars * 80% =

80 * .80 = 64

Movie ticket

14 original price

Sale price = 11.40

14* p% = 11.40

Divide each side by 14

p% = 11.40/14

p% =81.4285714

You paid 81 3/7%

The discount is 100 -81 3/7%

18 4/7 % discount

Laptop

1000 original price

Sale price = 750

1000 * p% = 750

p% = 750/1000

p% =75%

You paid 75%

The discount is 100 -75%

25 % discount

Answer:

Below

Step-by-step explanation:

First item)

The original price of the video games is 80$ wich is 100%

This item has a 20% discount.

Let x be the value of the dicount in dollars.

● 80 => 100

● x => 20

● x =(80×20)/100 = 16$

So the amount of the discount is 16$.

● 80-16 = 64 $

So the amount that was paid is 64$

■■■■■■■■■■■■■■■■■■■■■■■■■■

Second item):

The price that was paid is 11.2$out of 14$ initially.

Let x be the percentage of 11.2

● 14$ => 100%

● 11.2$ => x

● x = (11.2×100)/14 = 80%

● 100-80 = 20%

So the percentage of discount was 20%

■■■■■■■■■■■■■■■■■■■■■■■■

Third item):

The laptop was boughr for 750$ out of 1000$ initially

No need to do calculations here.

Notice that: 750/1000 = 3/4 = 0.75 = 75%

● 1000-750 = 250

So 250 is the amount discounted wich is 25% of 1000$

Answer:

D. x = 3+i√5 or 3-i√5

Step-by-step explanation:

Given the equation x² - 6x = -14, on rewriting the equation in the firm if a quadratic equation ax²+bx+c = 0 will give x² - 6x + 14= 0.

Required

Use the quadratic formula to solve the equation.

The quadratic formula is expressed as x = (-b±√b²-4ac)/2a

From the equation given, a = 1, b = -6 and c = 145.

x = (-(-6)±√(-6)²-4(1)(14))/2(1)

x = = (6±√36-56)/2

x = = (6±√-20)/2

x =  (6±√20*√-1)/2

Since √-1= i

x =  (6±√20 i)/2

x =  (6±√5*4 i)/2

x =  (6±2√5 i)/2

x = 6/2 ± 2√5 i/2

x = 3±√5 i

x = 3+i√5 and 3-i√5

Hence the solution to the quadratic equation is x = 3+i√5 and 3-i√5

Answer:

The answer is option 2.

Step-by-step explanation:

First, you have to find the height of the triangle using Cosine Rule, cosθ = adjacent/hypotenuse :

[tex]cos(θ) = \frac{adj.}{hypo.} [/tex]

[tex]θ = 30,adj. = h,hypo = 18[/tex]

[tex] \cos(30) = \frac{h}{18} [/tex]

[tex]18 \cos(30) = h[/tex]

[tex]h = 9 \sqrt{3} \: m[/tex]

Next, you have to find the area of triangle using Sin Rule, Area = 1/2×a×b×sinC where a, b represent the side length of the angle and C is the angle :

[tex]area = \frac{1}{2} \times a \times b \times sin(C)[/tex]

[tex]let \: a = 9 \sqrt{3} ,b = 18,C = 30[/tex]

[tex]area = \frac{1}{2} \times 9 \sqrt{3} \times 18 \times \sin(30) [/tex]

[tex]area = 70.1 \: {m}^{2} \: (near.tenth)[/tex]

Answer:

70.1

Step-by-step explanation:

This is a 30-60-90 right triangle.

The ratio of side lengths is as follows:

short leg   :   long leg   : hypotenuse

    1            :    sqrt(3)     :       2

The short leg is 1/2 the hypotenuse.

The long leg is sqrt(3) times the short leg.

A = bh/2

A = (18/2)(18/2 * sqrt(3))/2

A = 70.1

Also, note that sine and cosine function don't have asymptotes.

The vertical asymptotes of cosecant occur every [tex]\pi n, n\in\mathbb{Z}[/tex]

Hey there! I'm happy to help!

We want to put this 0.002 into scientific notation, where you put it as a one digit number multiplied by 10 raised to a certain power.

If we move the decimal to the right 3 times, we will have 2. We will multiply this 2 by [tex]10^-^3[/tex] to show that it is still equal to 0.002.

So, the mass of the mustard seed is 2×[tex]10^-^3[/tex].

Now, we multiply this mustard seed mass by the number of mustard seeds to find the weight of all of the mustard seeds combined.

(2×[tex]10^-^3[/tex])×(4.3602×[tex]10^4[/tex])

Let's round 4.3602 to the nearest whole number, which is 4. We multiply those two together.

2×4=8

And we multiply the two exponents. When multiplying them, you add the numbers in the exponent. -3 and 4 combined gives us 1, and 10 the first power is just 10.

So, a good estimate for the mass of the mustard seeds is 80 grams, which is the same as (2×[tex]10^-^3[/tex])×(4×[tex]10^4[/tex])=8×[tex]10^1[/tex]

Have a wonderful day! :D

Answer:

Hey There!! The answer to this is B: The mass of a single seed can be written as

There are total of seeds in the jar

Total mass is the multiplication of these both numbers.

Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.

The rule to multiply two numbers in scientific notation is:

So using this formula we multiply the 2 numbers and get answer as follows:

Thus, Answer choice B is right.

Woah woah, no need to panic! I’ve got this taken care of for you!

1. 0.01 divided by 1,000= 100,000.000

Change the divisor 0.01 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

100000 ÷ 1 = 100,000.000

and therefore:

1,000 ÷ 0.01 = 100,000.000

Both calculated to 3 decimal places.

2. 0.012 divided by 100= 8,333.333

Change the divisor 0.012 to a whole number by moving the decimal point 3 places to the right. Then move the decimal point in the dividend the same, 3 places to the right.

We then have the equations:

100000 ÷ 12 = 8,333.333

and therefore:

100 ÷ 0.012 = 8,333.333

Both calculated to 3 decimal places.

3. 0.000851 divided by 10= 11,750.881

Change the divisor 0.000851 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.

We then have the equations:

10000000 ÷ 851 = 11,750.881

and therefore:

10 ÷ 0.000851 = 11,750.881

Both calculated to 3 decimal places.

Answer:

Step-by-step explanation:

"Which ordered pair" implies that there were several answer choices for this problem.  It's important that you share such answer choices.

2x+4y=6x−y reduces to 5y = 8x, and so y = (8/5)x

If we choose x = 2, then y = (8/5)(2) = 16/5 is a solution of the given equation.  There are an infinite number of such solutions.  All lie on the line y = (8/5)x.

Answer:

19.5

Step-by-step explanation:

The Volume of a cone is h/3(r²)[tex]\pi[/tex]

That means, for the larger cone,

66=h/3(3²)([tex]\pi[/tex])

66=h/3*9[tex]\pi[/tex]

66/9[tex]\pi[/tex]*3=h

h=7, so the height of the larger cone is seven

Since the cones are similar, it has to have the same ratio. 7/3 of 2 is 4.6666.  So the height of the smaller cone is 4.66666.

Putting that in the formula,

V=(4.66666/3)(2²)[tex]\pi[/tex]

V=1.555555*4*[tex]\pi[/tex]

V=19.547
