Reflect the point (6, -7) across the x-axis

do have an equation or graph or

step-by-step explanation:

i think this is a open ended question but i agree with other guy who said you should ask it at english section

2

step-by-step explanation:

i'm truly not sure if this is correct, but if you just want to simplify the equation, you would divide everything by two to get x + 6x= 16

if you want to solve-

7x=16

x= 16/7

during a tunnel construction project, engineers used explosives to excavate partway into a mountain. but due to constraints and environmental concerns, they later introduced a tunnel boring machine (tbm) to excavate the rest of the tunnel. the length and of the completed tunnel (in feet) is based on the number of days since the tbm started working. the length can be calculated using the equation y = 25x + 225. what does the y-intercept represent in this scenario?
