Answer:
a 25 questions, 4 points b 19 questions
Step-by-step explanation:
a 96:100 = 24 : x
x = (100 x 24)/96 = 25 questions
100 : 25 = 4 points
b 76:100 = x : 25
x = (76 x 25)/100 = 19 questions
Answer:
first graph shows the function and it's inverse
Answer:
Step-by-step explanation:
Coordinates of the vertices of quadrilateral ABCD are,
A(-5, 8), B(-3, 10), C(1, 6) and D(-3, 5)
Rule for the rotation of point (x, y) by 180° about the origin is,
(x, y) → (-x, -y)
By applying this rule image of ABCD will be,
A(-5, 8) → A'(5, -8)
B(-3, 10) → B'(3, -10)
C(1, 6) → C'(-1, -6)
D(-3, 5) → D'(3, -5)
