The polynomial p(x)=(3-2x)(x^2-5) is graphed in a coordinate plane. Which statement about the graph is correct?

satela [25.4K]

Answer:

0 = (3-2x) x (x x 2 -5)

(3-2x) x ( x x 2 - 5) = 0

(3-2x) x (2x - 5) = 0

3 - 2x = 0

2x - 5 = 0

x = 3/2

x = 5/2

x1 = 3/2 or x2 = 5/2

What is the equation of the line that passes through the point (-6,-6)and has a slope of -\frac{1}{3}− ?

Gnesinka [82]

Answer:

y +6 = (-1/3)(x +6)

Step-by-step explanation:

Given a point and a slope, it is appropriate to use the point-slope form to represent the equation:

y -k = m(x -h) . . . . . line with slope m through point (h, k)

For your point and slope, the equation is ...

y -(-6) = -1/3(x -(-6))

y +6 = -1/3(x +6)

Of course, this can be rearranged to whatever form you need.

y = -1/3x -8 . . . . slope-intercept form

x +3y = -24 . . . . standard form

The sum of the first 100 positive whole numbers is 5050. What is the sum of the first 100 positive odd whole number?

Rufina [12.5K]

The series of odd numbers is:

1, 3, 5, 7, 9, 11, 13, ....

If you observe this series, it is an Arithmetic Series with first term as 1 and common difference of 2. Common difference is defined as the difference between two consecutive terms of the series. So by using the formula of sum of an Arithmetic Series, we can find the sum of first 100 positive odd whole numbers.

The formula for the sum of an Arithmetic Series is:

$S_{n}=\frac{n}{2}(2a_{1}+(n-1)*d)$

Here,

n = number of terms = 100

a₁ = first term = 1

d = Common Difference = 2

Using the values, we get:

$S_{100}=\frac{100}{2}(2(1)+99*2)\\ \\ S_{100}=10000$

Thus, the sum of first 100 positive odd whole numbers is 10,000.

in Ryan's V. Class 50% of the students like the teacher if 15 of the students like the teacher how many students are in that cla

Anton [14]

Answer: 30 students.

Step-by-step explanation: They are saying 50% of the class like the teacher. We know that 50% is half of the 100% so that mean only half of the students like the teacher. Is 15 students like the teacher it means that 15 are half of the students in the class. The other half should be another 15. So 15+15=30 or 15x2=30.

I hope I didn’t make it to confusing.
