Answer:
Step-by-step explanation:
Divide using synthetic division
Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13
Two lines are perpendicular if and only if the two lines intersect at right angles. If a point is in fourth quadrant,then it coordinates at negative. If thecoordinates are negative, then thepoint is in the fourth quadrant. If a figure is a triangle, then it has three sides.

Answer:
a = - 1
Step-by-step explanation:
given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Then the x-coordinate of the vertex is
• = -
The line of symmetry passes through the parabola, hence x-coordinate is 4
y = ax² + 8x - 3 is in standard form
with a = a, b = 8 and c = - 3, hence
- = 4 ( multiply both sides by 2a
- 8 = 8a ( divide both sides by 8 )
a = - 1
