If a: b = 2:3, b: c = 4:3, and c: d = 7: 8, find a: d.

Taya2010 [7]

Answer:

a:d=7:9

Step-by-step explanation:

We have a system with 3 equation:

$\frac{a}{b}=\frac{2}{3}\\\frac{b}{c}=\frac{4}{3}\\\frac{c}{d}=\frac{7}{8}$

If we multiply all of these equations, then we have:

$\frac{a}{b}*\frac{b}{c}*\frac{c}{d}=\frac{2}{3}*\frac{4}{3}*\frac{7}{8}\\\frac{a*b*c}{b*c*d}=\frac{2*4*7}{3*3*8}\\\frac{a}{d}=\frac{56}{72}$

If we simplify this fraction dividing by 9, then:

$\frac{a}{d}=\frac{56:9}{72:9}=\frac{7}{9}$

Therefore, a:d=7:9

Pleasee help !!! finding equation of the image

Lisa [10]

Answer:

Step-by-step explanation:

Here, we want to write the final formula for the equation after performing the given transformations

Reflection on the y-axis means the x-axis value will change sign

that will give:

y = -x^1/3

Transition of 3 units in the positive x axis

mathematically, we are adding 3 to x

so we have

y = -(x+3)^1/3

4 units in the negative y direction means we are subtracting 4 from the whole equation

That means;

y = -(x + 3)^1/3 - 4

This shows that the first option is right
