Answer:

a=(c+2b)/5

Step-by-step explanation:

Like terms in one side to subject a.

When exchanging sides make sure u do inverse operations. Therefore;

9a - 4a = c + 2b

5a = c + 2b

a = (c+2b)/5

The vertex of the parabola below is at the point (4, -1). Which of the equations below could be the one for this parabola?

kari74 [83]

One possible equation for this quadratic would be

y=(x-4)²-1. This is vertex form: y=a(x-h)²+k, where (h, k) is the vertex.

However, this is not the only possible equation. There could be multiple values for a, in front of the parentheses, that we don't know about from the information we are given.

We can also write this equation in standard form (y=ax²+bx+c). First write the squared binomial as the product of two binomials:
y=(x-4)(x-4)-1

Multiply the binomials:
y=x*x-4*x-4*x-4(-4)-1
= x²-4x-4x--16-1
= x²-8x+16-1
= x²-8x+15

Again, this would change depending on what the value of a is in the functoin.

Which statement is best supported by the dot plot? Choose ONE and explain your

maksim [4K]

Answer:

The statement that is best supported by the dot-plot is iii)

The mode of the number of miles Amanda skated in July is equal to the

mode of the number of miles skated in August.

<u>This is a true statement.</u>

The mode of the number of miles Amanda skated in July is equal to 1.

The mode of the number of miles Amanda skated in August is equal.

Step-by-step explanation:

i) The range of the number of miles Amanda skated in August is less than the

range of the number of miles she skated in July.

This is a true statement.

the range of the number of miles Amanda skated in August is 1 to 3

the range of the number of miles Amanda skated in July is 1 to 4

ii) The distribution of data is approximately symmetrical in both sets of data.

This is NOT a true statement.

the distribution of data of the number of miles Amanda skated in August

is not symmetrical.

the distribution of data of the number of miles Amanda skated in August

is approximately symmetrical.

iii) The mode of the number of miles Amanda skated in July is equal to the

mode of the number of miles skated in August.

This is a true statement.

The mode of the number of miles Amanda skated in July is equal to 1.

The mode of the number of miles Amanda skated in August is equal.
