Fed [463]3 years ago

Answer:

Step-by-step explanation:in standard form y= ax+b

-4y = -3x+28

4y =3x-28

or y= 3/4 x -7

So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)

Equation 3 is

y= 3/4x-2

which also has slope = 3/4 and y intercept = -2

Parallel lines have same slope

Similarly a perpendicular line will have slope of - 1/a

For equation

y= ax+b

Perpendicular line is

y=( -1/a) x +c

Answer:

The slope is 300

Step-by-step explanation:

Rise over run we see two points how many times do we rise and run to get there?

(Slope= rise/run)

So you rise 300 times (Since half of 600 is 300) then you run 1 time which is 300/1 which is 300

Answer: There are 12 white and blue cars more than silver and red cars

Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42

Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30

How many more white and blue cars are there than silver and red cars?
n=?

n=n3-n6=42-30→n=12

Answer: There are 12 white and blue cars more than silver and red cars.

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only
Marina CMI [18]

Answer:

54

Step-by-step explanation:

Surface area of triangular prism = bh + L(s1 + s2 + s3)

Where,

b = 3

h = 4

L = 3.5

s1 = 3

s2 = 4

s3 = 5

Plug in the values into the equation

Area of the triangular prism = 3*4 + 3.5(3 + 4 + 5)

= 12 + 42

= 54 units²
