Answer:
4) J
5) D
Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7
Answer:
The positive difference between the a values is 0.5
Step-by-step explanation:
we know that
Both parabolas cross the x axis at (-4,0) and (6,0)
so
The general equation is
<em>Find the value of a in the first parabola</em>
The y-intercept is (0,-12)
so
For 
substitute
<em>Find the value of a in the second parabola</em>
The y-intercept is (0,-24)
so
For 
substitute
<em>Find the positive difference between the a values for the two functions</em>
so
Answer:
1/40
Step-by-step explanation:
2/4*7/10
=2/28/10
=0.0714/10
=0.00714
Answer:
100
Step-by-step explanation:
triangles are equal to 180 degrees so in the one triangle 180-50-50=80 so that missing angel is 80 and then to creat a straight line between the missing angle m<1 and the 80 you subtract the two 180-80=100 leaving the missing angle to be 100
