Answer:

if you are required to find the equation of a straight line use the formula y-y1= m (x-x1)

y+2=-3(x-1)

y+2=-3x+3

y= -3x+3-2

y -3x+1

hope this helps

Answer:

y = -3x + 1

Step-by-step explanation:

(y -(-2)) = -3(x-1)

y+ 2 = -3x+ 3

y = -3x + 1

We will set each parentheses equal to 0
x - 4 = 0
x = 4
-5x + 1 = 0
x = 1/5
The lesser value will be 1/5

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv

Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. $P(Red) = 0.4375$

b. $P(White) = 0.3125$

Step-by-step explanation:

Given

$Red = 7$

$White = 5$

$Yellow = 4$

First, we need to calculate the total

$Total = Red + White + Yellow$

$Total = 7+5+4$

$Total = 16$

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{7}{16}$

$P(Red) = 0.4375$

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

$P(White) = \frac{White}{Total}$

$P(White) = \frac{5}{16}$

$P(White) = 0.3125$

If a scale is 1:250,000 and the distance is 8.5cm on the map what's the actual distance

timurjin [86]

8.5cm · 250,000 = 2,125,000cm

1m = 100cm therefore 1cm = 0.01m

2,125,000cm = 2,125,000 · 0.01 = 21,250m

1km = 1,000m therefore 1m = 0.001km

21,250m = 21,250 · 0.001km = 21.25km

Answer: 21,250m = 21,25km
