16+90+2y =180 since it is a straight line

106 +2y = 180

subtract 106 from each side

2y = 74

divide by 2 on each side

y=37

90+2y+O = 180 since it is a straight line

90 + 2(37) +O = 180

90+74 +O = 180

164+0 =180

subtract 164 from each side

O = 16

O +4x+90=180 sine it is a straight line

16 + 4x +90 = 180

106 +4x = 180

subtract 106 from each side

4x = 74

divide by 4

x=18.5

Answer:

An estimted 350 passengers.

Step-by-step explanation:

Let's estimate this sum: replacing 218 with 220 and 129 with 130, we have the simpler addition problem 220+130, which works out to 350 passengers (total on the two trains).

Write the equation of the line with the following characteristics.

Alika [10]

Answer:

y = 7x

y = 2x -3

y = 3

x = -2

Step-by-step explanation:

Slope-intercept form: y= mx+b
Parallel lines have same slope

a)Parallel to y=7x+2 through the point (0,0)

This line will have a form:

y= 7x + b

Considering the given point of (0,0), to find the value of b:

0= 7*0+b ⇒ b =0

The line is:

y = 7x

b)Slope of 2 through the point (0,−3)

Solving as above:

y= 2x + b
-3 = 2*0 + b ⇒ b = -3
y = 2x -3

c)A horizontal line through the point (0,3)

A horizontal line will have constant value for y for any value of x:

y = 3

d)A vertical line through the point (−2,0)

A vertical line will have constant value of x for any value of y:

x= -2
