Step-by-step explanation:
Gerald is constructing a line parallel to line l through point P. He begins by drawing line m through points P and Q. He then draws a circle centered at Q, which intersects line l at point N and line m at point S. Keeping the compass measure, he draws a congruent circle centered at point P, which intersects line m at point T.
Which next step will create point R, such that when a line is drawn through points P and R, the line will be parallel to line l?
Lines m and n intersect at point Q. A circle is drawn around point Q and forms point S on line m and forms point N on line l. Point P is also on line m. A circle is drawn around point P and forms point T on line m.
Use the compass to construct a circle centered at Q through point P.
Using the compass measure between points S and N, draw an arc to the right of line m, centered at T, intersecting the edge of circle P.
Using the compass measure between points S and N, draw an arc above line l, centered at N, intersecting the edge of circle Q.
Use the compass to construct a circle centered at P through point Q.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope. The correct option is C.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 2x + 2 , thus its slope is 2 and thus, the slope of the needed line is 2 too.
The next step that Gerald should take is Using the compass measure between points S and N, draw an arc to the right of line m, centered at T, intersecting the edge of circle P.

Answer:
a. t = 3 + √15 or t = 3 - √15
b. t = 6.87 or t = -0.87
Step-by-step explanation:
a.
Given : t² = 6t + 6
t² = 6t + 6 ⇔ t² - 6t + 6 = 0
USING THE QUADRATIC FORMULA:
[tex]t=\frac{6\pm \sqrt{\left( -6\right)^{2} -4\left( 1\right)(-6) } }{2}[/tex]
Then
[tex]t=\frac{6\pm \sqrt{36 +24 } }{2}[/tex]
Then
[tex]t=\frac{6\pm \sqrt{60 } }{2}[/tex]
Then
[tex]t=\frac{6\pm 2\sqrt{15 } }{2}[/tex]
Then
t = 3 ± √15
Then
t = 3 + √15 or t = 3 - √15
…………………………………………………
b.
t = 3 + √15 = 6.872983346207 ≈ 6.87
or t = 3 - √15 = -0.872983346207 ≈ -0.87
Which equations are true for x = -2 and x = 2? Select two options
A x²-4=0
B x²=-4
B 3x² + 12 = 0
C 4x² = 16
D 2(x-2)² = 0
Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
Answer:
Answer A and C
Step-by-step explanation:
Let us solve the equations one by one and let us check whether the answers are matching with the answers given in the questions.
A) x² - 4 = 0
( x² - 2² ) = 0
( x -2 ) ( x + 2 ) = 0
∴ x - 2 = 0 or x + 2 = 0
x = 2 x = -2 ( Matched )
B) x² = -4
x = ±√-4 ← no real solutions (Not matched )
B) 3x² + 12 = 0
3 ( x² + 4 ) = 0
3 ( x² + 2² ) = 0 ← no real solutions (Not matched)
C) 4x² = 16
Divide both sides by 4.
x² = 4
x = ±√4
∴ x = 2 or x = -2 (Matched)
D) 2 ( x - 2 )² = 0
(2x - 4)² = 0
4x² - 16x + 16 = 0
Divide the whole equation by 4.
x² - 4x + 4 = 0
x² - 2x - 2x + 4 = 0
x ( x - 2 ) - 2 ( x - 2 ) = 0
( x - 2 ) ( x - 2) =
∴ x - 2 = 0 or x - 2 = 0
x = 2 x = 2 ( Not matched )
