9x3 – 39x2 – 30x
Given:
The expression is
[tex]9x^3-39x^2-30x[/tex]
To find:
The factors by grouping method.
Solution:
We have,
[tex]9x^3-39x^2-30x[/tex]
Taking out common factors, we get
[tex]=x(9x^2-39x-30)[/tex]
Splitting the middle term, we get
[tex]=x(9x^2-45x+6x-30)[/tex]
By grouping method, we get
[tex]=x(9x(x-5)+6(x-5))[/tex]
[tex]=x(x-5)(9x+6)[/tex]
Therefore, the factor form of given expression is x(x-5)(9x+6).

A large bluefin tuna caught by fishing boat A in the Atlantic Ocean wighed 1305 pounds. This is 796 pounds less than 6 times the weight of a bluetin tua caught by fishing bout B in the Atlantic Ocean. Find the weight of the tur
caught by fishing boat B in the Atlantic Ocean
The weight of the tuna caught by fishing bout B pounds
Answer:
350.17 pounds
Step-by-step explanation:
Set up an equation where x is the weight of the tuna from bout B:
1305 = 6x - 796
Solve for x:
2101 = 6x
350.17 = x
So, the weight of the tuna is approximately 350.17 pounds

Answer:
(x, y) = (-4, 3)
Step-by-step explanation:
x + y = -1 $|Rightarrow$ x = -1 - y
x - y = -7
Substituting the value of x (first equation) into the second equation, we get:
(-1 - y) - y = -7.
Simplifing, we get:
-1 -2y = -7
-2y = -6
y = 3.
Now that we know the value of y, we can solve the value of x by substituting y into the first equation. We get:
x = -1 - 3
x = -4

If a(x) = 3x + 1 and b(x)= VX-4, what is the domain of (bºa)(x)?

The domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex].
How to apply composition between functions
The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:
[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]
[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex] (1)
Since the composite function is a square root function, then the domain fulfill the following inequation:
[tex]3\cdot x -3 \ge 0[/tex]
[tex]x \ge 1[/tex]
Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

The list shows the numbers of each type of pie baked at a bakery today.
• 13 apple
• 4 pecan
• 3 pumpkin
What percentage of the pies baked today were NOT apple?
The percentage of pies baked that were not apple was 33.33 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The number of apple pies baked at the bakery = 13
The number of pecan pies baked at the bakery = 4
The number of pumpkin pies baked at the bakery = 3
So ,
Total number of pies baked at the bakery =
Number of apple pies baked at the bakery + Number of pecan pies baked at the bakery + Number of pumpkin pies baked at the bakery
Total number of pies baked at the bakery = 13 + 4 + 3
= 21
Now ,
The number of pies that were not apple = Number of pumpkin pies baked at the bakery + Number of pecan pies baked at the bakery
The number of pies that were not apple = 4 + 3
= 7
And ,
The percentage of pies that were not apple =
( The number of pies that were not apple / Total number of pies baked at the bakery ) x 100 %
The percentage of pies that were not apple = ( 7 / 21 ) x 100 %
= ( 1 / 3 ) x 100 %
= 33.33 %
Hence , the percentage of pies that were not apple is 33.33 %

A rental truck costs $96 per day plus $0.60 per each mile. If Calvin can spend a maximum of $120, how many miles can he drive the rental truck?
Answer:
40 miles
Step-by-step explanation:
You would have to start by doing $120 - $96 for the per-day fee, which leaves Calvin with $24 to spend on miles.
Next you would do $24 ÷ $0.60 to find the number of miles he can drive, which is 40 miles.

Write the equation of the line that has a slope of ½ and a y-intercept of -2.
Answer (assuming it can be in slope-intercept form):
[tex]y = \frac{1}{2}x-2[/tex]
Step-by-step explanation:
When knowing the slope of a line and its y-intercept, you can write the line's equation in slope-intercept form, or y = mx + b format. To write a full equation, substitute the m and the b for real values.
The m represents the slope of the line. Thus, substitute [tex]\frac{1}{2}[/tex] for m. The b represents the y-intercept. Thus, substitute -2 for b. This gives us the following equation and answer:
[tex]y = \frac{1}{2}x -2[/tex]
