Step-by-step explanation:
(5)
Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and
∠ABC + ∠CBD = ∠ABD, that is
2x + 3x - 10 = 90, simplifying
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20, thus
∠ABC = 2x = 2 × 20 = 40°
∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°
(6)
4x - 18 = 3x + 7 ( vertical angles are congruent )
Subtract 3x from both sides
x - 18 = 7 ( add 18 to both sides )
x = 25
7y = 5y + 28 ( vertical angles are congruent )
Subtract 5y from both sides
2y = 28 ( divide both sides by 2 )
y = 14
The rate of change of function 1 (a horizontal line) is zero.
The rate of change (slope) of function 2 is the x-coefficient, 8.
8 is 8 more than 0.
The 4th selection is appropriat:
8

Step-by-step explanation:
Math definition Mode means anything that repeats more than anything else.
Eg.(4, 5, 6, 2, 2, 4, 4, 4, 4, 5, 3, 5)
The mode in the bracket is 4. Some of the numbers occured more than once but 4 occured the most that's why it's 4
