Which ratio is equivalent to 3:9? 24:54 18:54 36:81

docker41 [41]

Answer:

18:54

Step-by-step explanation:

We have to simplify these ratios.

If the most simplified form of the ratios are equal, they are equivalent

3:9

$r = \frac{3}{9} = \frac{1}{3}$

24:54

$r = \frac{24}{54} = \frac{12}{27} = \frac{4}{9}$

18:54

$r = \frac{18}{54} = \frac{9}{27} = \frac{3}{9} = \frac{1}{3}$

Same ratio as 3:9, so 18:54 is equivalent to 3:9

36:81

$r = \frac{36}{81} = \frac{12}{27} = \frac{4}{9}$

Answer:

the equation (x-4)^2-17=8 has two solutions because it is in a quadratic form.

(x-4)^2-17=8

x²-8x+16-17-8=0

x²-8x-9=0

Doing middle term factorization

x²-9x+x-9=0

x(x-9)+1(x-9)=0

(x-9)(x+1)=0

either

x=9

x=9or

x=9orx=-1

x^2+4x+3=0:

Doing middle term factorization

x²+3x+x+3=0

x(x+3)+1(x+3)=0

(x+3)(x+1)=0

either

x=-3

x=-1

Josh’s solution is incorrect because he missed x=-3.

3.

x^2-6x+7=0

By using quadratic equation formula:

Comparing above equation with ax²+bx+c=0

we get

a=1

b=-6

c=7

Now

we have

x= $\frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a}$

x= $\frac{ 6± \sqrt{ {-6}^{2} - 4*1*7} }{2}$

x= $\frac{ 6±2\sqrt{ 2}}{2}$

x= ${ 3±\sqrt{ 2}}$

Taking positive

x= ${ 3+\sqrt{ 2}}$

taking negative

x= ${ 3-\sqrt{ 2}}$

What do coordinate pairs on the graph of a straight line represent?

svp [43]

An ordered pair (x, y) represents a position of a point on a coordinate graph, where x is the number on the x-axis that the point lines up with and y is the number on the y-axis that the point lines up with. The numbers x and y in the ordered pair (x, y) are called coordinates
i hope this is what you meant
