Find equation where line passes through (7,8) and perpendicular to line y=8

Mathematics

forsale [732]3 years ago
5 0
Since in y=8, the slope is 0 (because there is no x) and b is 8 in y=mx+b, we know that the perpendicular line is x=(something) because the perpendicular lines of y=<number> are x=<number> due to that y=<number> equations are strictly horizontal while x=<number> equations are strictly vertical. Since we know that x=<number> has to pass through (7, 8), x =7

Find the coordinates of the midpoint M of ST. Then find the distance between points S and T. Round the distance to the nearest
ololo11 [35]

Answer:

Step-by-step explanation:

M is the midpoint

=>\left \{ {{x=\frac{6+7}{2} } \atop {y=\frac{-3-2}{2} }} \right

⇔\left \{ {x=\frac{13}{2} } \atop {y=\frac{-5}{2}}} \right.

⇒M(\frac{13}{2};\frac{-5}{2})

ST=\sqrt{(7-6) ^{2} +(-2+3)^{2}=\sqrt{2}=1.414

Mr. Pham wrote the equation below on the board.
Zielflug [23.3K]

Answer:

  5.5

Step-by-step explanation:

Given:

  18 -7x = -20.5

We can find x by subtracting 18, then dividing by the coefficient of x. (This is known as a 2-step equation.)

  -7x = -38.5 . . . . . subtract 18 from both sides

  x = -38.5/-7 = 5.5 . . . . .divide by -7

The value of x is 5.5.

The equation (x − 5)2 + (y + 3)2 = r2 represents circle T. The point S(-1,6) lies on the circle. What is r, the length of the ra
adell [148]

Answer:

r = 2.4  

Step-by-step explanation:

First of all, note that point S(-1,6) corresponds to S(x,y), therefore:

x = -1

y = 6

Now putting the value of x and y into the equation: (x − 5)2 + (y + 3)2 = r²

(x − 5)2 + (y + 3)2 = r²

(-1 − 5)2 + (6 + 3)2 = r²

(-6)2 + (9)2 = r²

-12 + 18 = r²

6 = r²

r = √6 = 2.4

∴ r = 2.4
