Answer:

y = 3x+9

Step-by-step explanation:

We can use the slope intercept form

y = mx+b

where m is the slope and b is the y intercept

y = 3x +b

Substitute the point into the equation

6 = 3(-1) +b

6 = -3+b

Add 3 to each side

6+3 = -3+3+b

9 = b

y = 3x+9

The answer is C. when using the formula C=2*pi*r and A=pi*r^2.

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

What is y-8=3(x+1) written in standard form
Stels [109]
Standard form of a linear equation is Ax + By = C, where A, B, C are constants.

So,
y-8 = 3(x+1)
y-8 = 3x + 3

substract 3 from both sides,
y-8-3 = 3x+3-3
y-11 = 3x

substract y from both sides,
y-y-11 = 3x-y
-11 = 3x-y

So, the standard form is 3x-y = -11

Which of the following is an irrational number?
tamaranim1 [39]

Answer:

The correct option is;

0.100100010000...

Step-by-step explanation:

An irrational number in mathematics are the subset of real numbers that are not rational numbers such as √2, π, e. As such it is not possible to express an irrational number as a ratio of two integers, or expressed in the form of a simple fraction.

The decimal portion of the expression of an irrational number are non periodic and they do not terminate. Transcendental, which are non algebraic, numbers are all irrational numbers

In the question, the number 0.100100010000... has non terminating non recurring decimals and is therefore an irrational number.
