Easy way: type the equation into a graphing calculator.

__

By hand: find a couple of points and draw a line through them.

The equation is in "slope-intercept" form:

  y = mx + b

where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).

The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).

You can plot those two points and draw the line through them.

Given :

Three roots , [tex]\sqrt{7},\ -\sqrt{7},\ -4[/tex] .

To Find :

A cubic function with the given zeros.

Solution :

Equation of polynomial of 3 zeroes is given by :

[tex](x-a_1)(x-a_2)(x-a_3)=0\\\\(x-\sqrt{7})(x+\sqrt{7})(x+4)=0\\\\( x^2-7)(x+4)=0\\\\x^3+4x^2-7x-28=0[/tex]

Therefore, the cubic function of given zeroes is [tex]x^3+4x^2-7x-28=0[/tex].

Hence, this is the required solution.

Answer:

Pam's house to the restaurant: 5 units

Pam's house to Jean's house: 2 units

Jean's house to the school: 6 units

Step-by-step explanation:

The distance formula is: d=√((x_2 - x_1)²+ (y_2 - y_1)²)

So, plug the coordinates into the formula for each problem:

Pam's house to restaurant:

d=√((4 +1)²+ (-2 +2)²)

d=√(5²+ 0²)

d=√(25)

d=5

Pam's house to Jean's house:

d=√((-3 +1)²+ (-2 +2)²)

d=√(-2²+ 0²)

d=√(4)

d=2

Jean's house to the restaurant:

d=√((-3 +3)²+ (4+2)²)

d=√(0²+ 6²)

d=√(36)

d=6

So:

Pam's house to the restaurant: 5 units

Pam's house to Jean's house: 2 units

Jean's house to the school: 6 units

Step-by-step explanation:

subtract the e from both sides so you now have 15=5m divide each by 5 and you get 3=m

Answer:

m = 3

Step-by-step explanation:

-5m + 18 = 3

-5m = 3 - 18

-5m / -15 = 3

Answer: m = 3

Answer:

244,140,634

Step-by-step explanation:

Answer:

Rational

Step-by-step explanation:

2.7 can be written as a fraction, so therefore it is ration[tex]2.7=2\frac{7}{10} =\frac{27}{10}[/tex]al.

The number 2.7 is a rational number.

A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero.

In other words, a rational number can be written in the form p/q, where p and q are integers, and q is not equal to zero.

Now, let's express 2.7 as a fraction:

2.7 = 27/10

Since 27 and 10 are both integers, and the denominator (10) is not zero, we have successfully expressed 2.7 as a fraction of two integers.

Therefore, 2.7 is a rational number.

On the other hand, an irrational number cannot be expressed as a simple fraction of two integers. Examples of irrational numbers include π (pi) and √2 (the square root of 2).

These numbers have non-repeating and non-terminating decimal expansions, and they cannot be written as a fraction of two integers.

However, 2.7 is a terminating decimal (it has a finite number of decimal places), and it can be expressed as a fraction, making it a rational number.

i took the test and got a hundred! it's a trick question

The statements included in the explanation on the horizontal line test are follows as a reference to the horizontal-line test, a statement that the function is one-to-one. and inverse is a function.

The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.

In order to pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places.

If this happens, then there is an inverse and the inverse itself is a function.

The complete question is

If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function. Compare your response to the sample response above.
