Which of the following is the equation of a line perpendicular to the line Y=-1/3x+1, passing through the point (2,7)?

zimovet [89]

Y= 3X + 1. Perpendicular means you would change the slope by flipping it and changing the sign. So the slope then becomes 3. Then you use your points to find the y-intercept by filling in the variables. 7=3(2) + B. 7=6 + B. Then subtract 6 from both sides. B=1. Then you just put your problem back into slope intercept form with your new slope and y-intercept. Y=3x + 1.

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.

Factorise the following, using the identity a2 – 2ab + b2 = (a – b)2

Rasek [7]

The factorisation of the given expressions is as follows;

a) p²y²– 2py + 1 = (py -1)²
b) a²y² -2aby +b² = (ay - b)²

<h3>Factorization using identities</h3>

The given identity is;

a²– 2ab + b² = (a – b)²

From the given identity, we can conclude that;

In the expression (a);

py represents a in the identity and 1 represents b in the identity.

In the expression (b);

ay represents a in the identity and b represents b in the identity.

Hence, the factorised expressions are as represented above.
