Answer:

Step-by-step explanation:

So since both equations equal f(x), we can set them equal to each other

-15x - 13 = -28

Our next step is to get x by itself on one side of the equation. To do this, you:

Add 13 to both sides

-15x = -15

Divide both sides by -15

x = 1

Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

4x + 9y = -9

By converting this equation into y-intercept form,

9y = -4x - 9

$y=-\frac{4}{9}x-\frac{9}{9}$

$y=-\frac{4}{9}x-1$

By comparing this equation with y = mx + b

Here, m = Slope of the line

b = y-intercept

Slope of the equation (m) = $-\frac{4}{9}$

y-intercept (b) = -1

8). Equation of the line is,

5x + 3y = 12

3y = -5x + 12

$y=-\frac{5}{3}x+\frac{12}{3}$

$y=-\frac{5}{3}x+4$

Slope of the line = $-\frac{5}{3}$

y-intercept = 4

oee [108]

Answer:

117

Step-by-step explanation:

For every 3 zinc there would be 19 copper, and for every 19 copper there would be 3 zinc. There are 741 copper, so there would be 741 * 3 / 19 zinc, which turns out to be 117 zinc.
