Answer:
the answer would be divide, because of the negative 3 in the answer.
just remember when there is a negative in the equation it is almost always do the opposite.
have fun and be you <3
Step-by-step explanation:
Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± ← exact solutions
Answer:
If the triangle is reflected the new coordinate will be
R'(-3, 2), S'(-5, -2), T'(-6, 0)
Y = 2x + 3
Would be the answer with 2 being the slope and 3 being the y-intercept

Answer:
5. x° = 38°; b° = 90°
6. m∠TSU = 110°
Step-by-step explanation:
The relationship relevant to these problems is that <em>an inscribed angle is half the measure of the arc it intercepts</em>. That is also true of the angle formed by a chord and a tangent.
__
5. Angle x° intercepts an arc marked 76°, so is half its measure: 76°/2 = 38°
x° = 38°
Arc b° is intercepted by an inscribed angle of 45°, so is twice that measure.
b° = 90°
__
6. Long arc SU is the remaining portion of the circle after short arc SVU is subtracted:
long arc SU = 360° -140° = 220°
Angle TSU is half that measure: 220°/2 = 110°.
m∠TSU = 110°
