Answer:
4)x=2
5) (-3,4)
Step-by-step explanation:
4) f(x)=x^2-4x+4-4+5
f(x)=(x-2)^2+1
f(x)=a(x-h)^2+k
Axis of symmetry is x=h
h is 2, so axis of symmetry is x=2
5) f(x)=x^2+6x+9-9+13
f(x)=(x+3)^2+4
f(x)=a(x-h)^2+k
Vertex is (h,k)
So, vertex is (-3,4)
Sorry, I can't answer the first 3, cause I don't understand what a-value, b-value and c-value mean.
And also is this college math, cause I'm in middle-school, and I know how to do it.
A friend is building a 4-sided garden with two side lengths of 19 feet and exactly one right angle. What quadrilaterals could describe the garden?
Answer: The garden could be a square, rectangle or rhombus in shape. As given, the proposed garden has two sides with equal length of 19 feet and the garden is 4 sided. So, it can be a square, rectangle or rhombus.
Answer:
45.21960784 or 45.2
Step-by-step explanation:
Answer:
25
Explanation:
We are given the sequence formula expression;
ax = 3x + 4
You are to get the 7th term. This is gotten by substituting x = 7 into the expression as shown;
a7 = 3(7) + 4
a7 = 21 + 4
a7 = 25
Hence the seventh term of the sequence is 25
