Answer:
The bridge is 80 feet long
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The engineer used the scale 3 inch = 40 feet
∴ The scale drawing is ⇒ 3 inche : 40 feet
∵ The drawing length of the bridge is 6 inches
→ By using the ratio method
→ inch : feet
→ 3 : 40
→ 6 : x
→ By using cross multiplication
∵ 3 × x = 6 × 40
∴ 3x = 240
→ Divide both sides by 3
∴ x = 80
∵ x represents the actual length of the bridge
∴ The bridge is 80 feet long
Answer:
y intercept=3/2
Step-by-step explanation:
First of all, write it in slope intercept form
y=-1/6x+3/2
y=mx+b
b=y-intercept
y intercept=3/2

Answer:
Option C.
Step-by-step explanation:
Consider the complete question is "Triangle JKL is transformed using the rule 
. Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".
According to 
, we get
According to 
, we get
The rule means first reflection and then rotation.
We need to find the image of K(4,7).
After reflection, we get
After rotation, we get
Therefore, the correct option is C.
