3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
The sequence is not arithmetic
Answer:
The answer is D.
Step-by-step explanation:
Answer:
y = (x - 2)(x + 4)(x - 1)
Step-by-step explanation:
Given the zeros of a function say x = a and x = b, then
The factors are (x - a) and (x - b) and
y = (x - a)(x - b)
Given the zeros are x = 2, x = - 4, x = 1, then
the factors are (x - 2), (x - (- 4)) and (x - 1), that is
(x - 2), (x + 4), (x - 1) , thus
y = (x - 2)(x + 4)(x - 1)
Answer:
Part 4) Right triangle
Part 5) Kite
Step-by-step explanation:
Part 4) What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?
Using a graphing tool
see the attached figure N 
The triangle of the figure is not equilateral------> The triangle does not have three equal sides
The triangle of the figure is a right triangle------>The triangle has an angle of 
The triangle of the figure is not isosceles------> The triangle does not have two equal sides
The triangle of the figure is not a right and isosceles
Part 5) What type of quadrilateral is formed by connecting the points
?
Using a graphing tool
see the attached figure N
The figure is not a rhombus------> All sides are not congruent
The figure is not a trapezoid-----> has not parallel sides
The figure is a kite------> Two disjoint pairs of consecutive sides are congruent and the diagonals meet at a right angle
