Find the slope of the line.<br> y = -10x - 2
Pavlova-9 [17]

The slope is the change in y-axis to x-axis of a graph. The slope of the line given is -10

<h3>How to find the slope of a line?</h3>

The standard equation of a line in slope intercept form is given as y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the equation y = -10x - 2

Compare

mx = -10x

m = -10

Hence the slope of the line given is -10

Answer:

  (x, y) = (34/5, -4/5) = (6.8, -0.8)

Step-by-step explanation:

Subtract the first equation from the second to eliminate x.

  \left(\dfrac{x}{3}-\dfrac{y}{2}\right)-\left(\dfrac{x-5}{3}+\dfrac{y+2}{3}\right)=\left(\dfrac{8}{3}\right)-(1)\\\\y\left(-\dfrac{1}{2}-\dfrac{1}{3}\right)+\left(\dfrac{5}{3}-\dfrac{2}{3}\right)=\dfrac{5}{3} \qquad\text{partially simplify}\\\\-\dfrac{5}{6}y=\dfrac{2}{3} \qquad\text{subtract 1}\\\\y=-\dfrac{4}{5} \qquad\text{multiply by $-\dfrac{6}{5}$}

Substituting for y in the second equation, we can find x.

  \dfrac{x}{3}-\dfrac{1}{2}\left(-\dfrac{4}{5}\right)=\dfrac{8}{3}\\\\5x +6=40 \qquad\text{multiply by 15}\\\\5x=34\qquad\text{subtract 6}\\\\x=\dfrac{34}{5}

The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).

Round the following as specified.<br><br> 153.38519 to the nearest thousandth.
In-s [12.5K]

Answer:

153.3852

Step-by-step explanation:

After the decimal, you count the places. 3 is in the ones place, 8 in the tenths, 5 in the hundreths, and 1 in the thousandths. The thousandths place is what we are rounding, so we look at the next number, 9, which tells us to round the 1 up to 2
