Step-by-step explanation:
Find two values of "b" so that x^2 + b x + 6 can be factored into binomial factors.
Given:
The expression is
[tex]x^2+bx+6[/tex]
To find:
The values of b so that the given expression can be factored into binomials factors.
Solution:
An expression is [tex]ax^2+bx+c[/tex] factorable if b is the sum of possible factors of ac.
We have,
[tex]x^2+bx+6[/tex]
Here, [tex]a=1,b=b,c=6[/tex].
[tex]ac=(1)(6)[/tex]
[tex]ac=6[/tex]
Some, factor forms of 6 are (1×6) and (2×3).
[tex]1+6=7[/tex]
[tex]2+3=5[/tex]
For b=7,
[tex]x^2+7x+6=x^2+x+6x+6[/tex]
[tex]x^2+7x+6=x(x+1)+6(x+1)[/tex]
[tex]x^2+7x+6=(x+1)(x+6)[/tex]
For b=5,
[tex]x^2+5x+6=x^2+2x+3x+6[/tex]
[tex]x^2+5x+6=x(x+2)+3(x+2)[/tex]
[tex]x^2+5x+6=(x+2)(x+3)[/tex]
Therefore, the two possible values of b are 7 and 5.

There is a line that includes the point (9, 1) and has a slope of -8. What is its equation in
point-slope form?
Answer:
y - 1 = -8(x -9)
Step-by-step explanation:
Point-slope form is y - y1 = m(x - x1) given a point (x1, y1) on the line and slope m. Plug all the values in and this is the answer.

Answer:
scientific notation. I did this a few moths ago.
Step-by-step explanation:
since it is 10^8 you're going to move your decimal as far the right as you can which then changes it to 685. x 10^6. After that you add 6 zeros (from the 10^6) and change it from a decimal to a comma to get 658,000,000... i hope this helps

1. There are 16 boys and 18 girls in a Grade 6 math class. Write the ratio of girls to boys in words as simply as possible.
2. The ratio of blue marbles to yellow marbles is 5:1. For every yellow marble, there are ___ blue marbles.
Answer:
1.)8 boys yo 9 girls
2.)5
Step-by-step explanation:
1)divide by 2
2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble
The ratio of boys to girls in the Grade 6 math class is =
8 : 9.
For every yellow marble, there are five blue marbles.
To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.
To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.
Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.
The 5:1 ratio of blue to yellow marbles means for every yellow marble, there are five blue marbles.
