y = - 
x - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 7x + 5y = 12 into this form
add 7x to both sides
5y = 7x + 12 ( divide all terms by 5 )
y = 
x + 
← in slope- intercept form
with slope m =
given a line with slope m then the slope of a line perpendicular to it is
perpendicular slope = - 
= -
The partial equation of the perpendicular line is
y = - x + c
to find c substitute (- 7, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = - x - 1 ← in slope- intercept form

x = °

∗ The volume of that wedge is 1/2BHL
∗ The volume of a rectangular prism is LWH
∗ B = 8
∗ H = 5
∗ L = 11
∗ 1/2 • 8 • 5 • 11 = 220
∗ v = 220cm^3
∗ 2 wedges have a volume of 440cm^3
▪
∗ L = 8
∗ W = 12
∗ H = 5
∗ 8 • 12 • 5 = 480
∗ v = 480cm^3

∗ The question says "bikes" which refers to more than 1, and there are 3 people.
∗ It costs $18 a day to rent a bike.
∗ They are renting for 5 days.
∗ Let x represent the number of days.
∗ Let b represent the number of bikes.
∗ Let y represent the total cost.
∗ (b • 18)x = y
∗ (3 • 18)5 = y
∗ 54 • 5 = 270
∗ There are 3 people splitting the cost, so you divide 270 by 3 to get 90.
∗ Each person pays $90

Answer:
180
Step-by-step explanation:
draw it out it is a rectangle with length=15 and width = 12.
Area of a rectangle = LxW
=15x12
=180
Answer:
259.99
Step-by-step explanation:
You look at the hundreths place and see if the number behind it is bigger than 5, and if it is then you up it by one, and if it's 4 and below then you round it to zero. In this case you up it by one and you get 269.99.
I hope this helps!!!!
