Answer:
x = - 11
Step-by-step explanation:
y = 15 is a horizontal line parallel to the x- axis
a perpendicular line must therefore be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
the line passes through (- 11, - 1 ) with x- coordinate of - 11 , then
x = - 11 ← equation of perpendicular line
 
        
                    
             
        
        
        
Answer:
y - 2 = 5(x+1)
Step-by-step explanation:
Point slope form is 
y-y1 = m(x-x1)  where m is the slope and ( x1,y1) is a point on the line
y - 2 = 5(x- -1)
y - 2 = 5(x+1)
 
        
                    
             
        
        
        
Answer: 5 km walking and 30 km by bus
Step-by-step explanation: 
Yochanan walked from home to the bus stop at an average speed of 5 km / h. He immediately got on his school bus and traveled at an average speed of 60 km / h until he got to school. The total distance from his home to school is 35 km, and the entire trip took 1.5 hours. How many km did Yochanan cover by walking and how many did he cover by travelling on the bus?
walking - 5km/h                                         bus - 60km/h
distance walking - d₁                                 distance bus - d₂
time walking - t₁                                         time bus - t₂
d₁ + d₂ = 35
t₁ + t₂ = 1.5
v = d/t
vwalking = d₁/t₁
5 = d₁/t₁ ⇒ d₁ = 5t₁
vbus = d₂/t₂
60 = d₂/t₂ ⇒ d₂ = 60t₂
d₁ + d₂ = 35 ⇒ 5t₁ + 60t₂ = 35
_________________________
5t₁ + 60t₂ = 35
t₁ + t₂ = 1.5  (*-5)
5t₁ + 60t₂ = 35
-5t₁ -5t₂ = -7.5   (+)
__________________________
55t₂ = 27.5
t₂ = 27.5/55 = 0.5 h 
t₁ + t₂ = 1.5 ⇒ t₁ = 1.5 - 0.5 = 1h
d₁ = 5t₁ ⇒ d₁ = 5.1 = 5 km
d₂ = 60t₂ ⇒ d₂ = 30.0.5 = 30 km
 
        
             
        
        
        
Answer:
$20.98
Step-by-step explanation:
2 hours means two of 8.74 which equals 17.48 plus that $3.5 in a day. So she gets $20.98 when she works for 2 hours.
