Answer:

y = -x

Step-by-step explanation:

The slopes of parallel lines are equal

y = -x +5

The slope is -1 so the parallel also has a slope of -1

The equation of a line in slope intercept form is

y = mx+b

y = -1x +b

Substituting in the point (4,-4)

-4 = -1(4) +b

-4 = -4+b

Add 4 to each side

-4+4 = -4+4 +b

0=b

y = -x

The ratio of team leaders to players is 1:18. How many team leaders will be

mamaluj [8]

Answer:

Step-by-step explanation:

if the ratio is 1:18 that means for every 18 players there will be 1 team leader. A simple way to find the answer to problems involving ratios is to simply plug in the numbers. In this case the ratio is 1:18, so first plug in the number you have by dividing the amount of players by the original ratio given, so 72/1 = 1. This makes 72:18, then divide 72/18 = 4.

A line that passes through the points (–4, 10) and (–1, 5) can be represented by the equation y = y equals negative StartFractio

ioda

Answer:

The equation of line 5 x + 3 y = 10.

Step-by-step explanation:

Two points (- 4, 10 ) and (- 1, 5)

The equation of line passing through the two points is given by

$(y -y_{1})=\frac {y_{2}-y_{1}}{x_{2}-x_{1}}\times (x- x_{1})\\\\(y - 10)=\frac {5 - 10 }{- 1+ 4}\times (x +4)\\\\y -10 = \frac{-5}{3}\times (x +4)\\\\3 y - 30 =- 5 x - 20\\\\5 x + 3 y = 10$

The solution of the equation 3x+4=25

Lunna [17]

Answer:

$\huge \boxed{x=7}$

Step-by-step explanation:

3x + 4 = 25

Subtract 4 from both sides.

3x + 4 - 4 = 25 - 4

3x = 21

Divide both sides by 3.

(3x)/3 = 21/3

x = 7
