Factor completely: 3x2 + 9x − 3

3x2 + 9x − 3 (a 3 can be divided from each number)
3(x2+3x-1)

can x2+3x-1 be factored out anymore? no

3(x2+3x-1) is the answer

Answer:

Option (2) is correct choice.

Step-by-step explanation:

Given polynomial $3x^2+9x-3$

We have factorize the given polynomial and choose the correct from options given.

Factor are the smallest forms a given number is broken such that the product of factors gives back the number we factorized.

Here, $3x^2+9x-3$

First taking 3 common from whole expression.

$3x^2+9x-3=3(x^2+3x-1)$

Thus, option (2) is correct choice.

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

Definition

A radius is a line drawn from the center of a circle to its circumference.
A segment is a line that connects two points.
A diameter is a chord which passes through the center of the circle.
A chord is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|

Find the equation of the line shown.

dedylja [7]

Answer:

f(x)=2x

Step-by-step explanation:

You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.

Solve this equation. Please show work. log(4m-10)=1

Ede4ka [16]

Answer:

m=5

Step-by-step explanation:

1. Convert the logarithm into exponential form using the fact that $log_{a}$ (x)=b is equal to x= $a^{b}$ so ... 4m-10= $10^{1}$

2. Any expression raised to the power of 1 equals itself so ... 4m-10=10

3. Move the constant to the right-hand side and change its sign so ... 4m=10+10

4. Add the numbers so ... 4m=20

5. Divide both sides of the equation by 4 so ... m=5, m> $\frac{5}{2}$

6. Check if the solution is in the defined range so ... m=5
