how do i graph y=-x+3

Given:

The equation is

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

To find:

The value of [tex]b^2[/tex].

Solution:

We have,

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

On cross multiplication, we get

[tex]a\times c=b\times b[/tex]

[tex]ac=b^2[/tex]

[tex]b^2=ac[/tex]

Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

Answer :c

step by step explanation:

Answer:

no solution

Step-by-step explanation:

x²-4 is (x+2)(x-2), which is your least common multiplier

So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)

(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)

Then simplify

(x+2) + (6x) = 3(x-2)

combine the variables, and expand the right side of the equation

7x + 2 = 3x - 6

Subtract 2 from both sides

7x = 3x - 8

Substract 3x from both sides

4x = -8

Divide both sides by 4

x = -2

Although x = -2, the final answer is undefined.

Because if you plug x = -2 back into the equation, you would get...

for example, 3/(x+2) will become 3/(-2+2), which is 1/0

it is not possible to divide by 0

anything divided by 0 is undefined, therefore this equation has no solution.

Answer:

They have raised $500 so far

Step-by-step explanation:

Multiply $2500 by 20% (aka 0.2) and you get $500

(They need to raise another $2,000 still)

Answer:$500

Step-by-step explanation:

We could translate the world problem,to get an equation.

20% “of” 2,500. The “of” means that you have to multiply. Convert the percent to get 0.20, and multiply it by 2,500.

0.20*2,500=500

y = x² + 2x

Step-by-step explanation:

The pattern is

Step 1  ⇒ 1*3 = 3

Step 2 ⇒ 2*4 = 8

Step 3 ⇒ 3*5 = 15

Next step would be

Step 4 ⇒ 4*6 = 24

Answer:

approximately 83%

Step-by-step explanation:

Answer:

83%

So basically you take 12-2=10 and then do 10/12 and that = 0.83 and so 83% is the answer

Answer:

AB = 5[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A(6, 3) and (x₂, y₂ ) = B(- 1, 4)

AB = [tex]\sqrt{(-1-6)^2+(4-3)^2}[/tex]

     = [tex]\sqrt{(-7)^2+1^2}[/tex]

     = [tex]\sqrt{49+1}[/tex]

     = [tex]\sqrt{50}[/tex]

     = 5[tex]\sqrt{2}[/tex] ← exact value

     ≈ 7.07 ( to 2 dec. places )

Answer:

Answer:

(x+4)(x-3) or A

Step-by-step explanation:

I'm going to assume that you meant to write x² and not x2

which means we have

x²+x-12

and we need to factor this

to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)

our two numbers are

4, -3

Which means the answer is

(x+4)(x-3)

Answer:

2.50

Step-by-step explanation:

ok, so we start out with a 6 cup bag of cheese. But then she uses 2.25 cups to make lasgna, and 1.25 cups to make pizza. we need to see how much cheese is left after she used the cups. First lets add the 2 cups: 1.25 + 2.25. Lets first add 1 + 2 = 3, then .25 + .25 = .50. Lets now add 3, and .50, and that gives us 3.50. Now to see how much cheese is left, we must subtract 6 minus 3.50, which gives us a total of 2.50. I hope that helped!

Answer:

x = 128°

Step-by-step explanation:

Its an isosceles triangle, so it has 2 two sides of equal length. and from here we can say that it has two angles that are the same, 26° and 26° we know that in a triangle there are 180° in total so we add up the two angles we know 26+26=52 and subtract it by 180  which equals 128°

Answer:

$18.43

Step-by-step explanation:

19.61 decrease 6% =

19.61 × (1 - 6%) = 19.61 × (1 - 0.06) = 18.4334

The cost of the leotard before sales tax is $18.5

The sales tax is calculated by multiplying the total sales or selling price by the rate of sales tax.

Amount of sales tax = rate of sales tax × Total sales

Rate of sales tax = percent  of sales tax / 100

Let the cost of leotard before tax be x

Given that sales tax of 6% is applied over x

The the amount of sales tax =( 6/100) ×x = 3x / 50

The total cost after applying sales =  x + (3x/50) = 53x/50

Given that the total cost of purchasing a leotard including tax = $19.61

⇒ 53x/50 = 19.61

⇒53x = 19.61×50

⇒ x = 980.5/53 = 18.5

Therefore, the cost of the leotard before sales tax is $18.5

Answer:

Simplify 32(x^2+4x)

32x^2+128x=16(x^2+4x+3)

simplify 16(x^2+4x+3)

32x^2+128x=16x^2+64x+48

subtract 16x^2 from both sides

subtract 64x from both sides

subtract 16x^2 and 32x^2

subtract 64x from 128x
