Answer:
y = 7x - 14
Step-by-step explanation:
If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7. That is +7.
Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:
0 = 7(2) + b. Then b = -14, and the desired equation is y = 7x - 14.
Answer:
x=±sqrt (33)
Step-by-step explanation:
y=(x+2)(x-2)
29=x^2-4. x^2=33, x=±sqrt (33)
A decimal problem may be a addition problem you would need to regroup the hundredths to solve, like a money problem
2x3(S-+7)=6xS=7............
