What is the equation to (-3,1) and (0,-8)
puteri [66]
The change in x between the two is 3 and the change in y is -9. 
Divide -9 by 3 to get -3 using the rise over run slope formula.  
The equation is y = -8 + -3x because the -8 in the second set of coordinates is the y-intercept of the equation. 
Hope this helps!

Question below. Please answer it, its math.
AleksAgata [21]

Answer:

- 0.8

Step-by-step explanation:

The first thing we want to do here is simplify the expression -

\frac{3}{5}( 2x + 5 ) - 2x, Distribute the " \frac{3}{5} " to elements within the parenthesis

= \frac{3}{5} * 2x + \frac{3}{5} * 5 - 2x, Focus on simplifying the expression " \frac{3}{5} * 2x + \frac{3}{5} * 5 "

= 2\cdot \frac{3}{5}x+5\cdot \frac{3}{5} - 2x

= \frac{6x}{5}+3 - 2x, Combine fractions

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

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

So we have our simplified expression "  -\frac{4}{5}x + 3, " with -\frac{4}{5} being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,

- 4 / 5 = - 0.8,

Solution = - 0.8

If 20 machines produce 1,240 printers in a day,
d1i1m1o1n [39]

Answer:

12 machines

Step-by-step explanation:

The production rate per machine is 1240/20 = 62

For 1,984 printers it would take 32 machines (1984/62 = 32)

32 needed minus the 20 they already have means they need 12 more machines.
