if c/d - a/b =x, a =2c, and b=5d, what is the value of c/d in terms of x?

Answer:

d) 5/3 x

Step-by-step explanation:

You substitute a for 2c and b for 5d, so your equation will look like this:

c/d - 2c/5d = x

Then you just simplify into x by making c/d into 5c/5d so you have a common denominator.

5c/5d - 2c/5d = x

3c/5d = x

5/3 is your answer

Answer:

The point slope form is $y-y_{1} =m(x-x_{1} )$

The slope(m) can be calculated using $\frac{y-y_{1} }{x-x_{1}}$ :

$(x, y)=(4,-3)\\(x_{1} ,y_{1} )=(5,0)\\\\\frac{0-(-3)}{5-4} =\frac{0+3}{1} =\frac{3}{1} =3$

Using Point One, the point-slope form is determined as:

$y-(-3)=3(x-4)\\y+3=3(x-4)$

The y-intercept(b) can be calculated as:

$(5,0)\\y=3x+b\\0=3(5)+b\\0=15+b\\b=-15\\(0,-15)$
