Answer:
108 pens
Step-by-step explanation:
48/4=x/9
4x=432
x=108
Answer:
Since there are 12 pens packed in each box, because there are 48 packed in 4 boxes, there will be ( 12 times 9 ) 108 pens in 9 boxes.

If f(x)=3^ x-4 what is f(- 1) ?
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
Step-by-step explanation:
substitute (-1)

The length of a rectangular birthday party invitation is 1 inch less than twice its width. The area of the invitation is 15 square inches.
The length of a rectangular birthday party invitation is 9 inch.
The length of a rectangular birthday party invitation is 1 inch less than twice its width.
Area of the invitation 15 square inches.
what is the area of the rectangle?
A=length× width
That is,the area of a rectangle is length times width.
let x be the width rectangle
width = x
length = 2x - 1
[tex]Area= 15 square inches[/tex]
Using these variables, set up the equation for area.
x(2x - 1) = 15
Solve the equation for x.
[tex]2x^{2} - x = 15[/tex]
Subtract 21 on both sides of the equation.
[tex]2x^{2} - x - 15=0[/tex]
Which method we use to factor the polynomial?
FOIL method
Factor using FOIL, if possible.
(2x +5)(x - 5) = 0
Set the factors equal to zero and solve for x.
2x = -5 and x - 5 = 0
x =- 5/2 or x = 5
x =- 2.5 or x=5
Since we cannot accept a negative value for dimensions, we accept the positive value of x:
x = 5
Therefore,
Length = 2(5) - 1
Length = 10-1
Length = 9
Therefore we get the length is 9 inch

Miguel has triple David's money, while Lisbeth has ten dollars less than David. The sum of their money totals $95. How much money does David have?
Answer:
Miguel has $63
Lisbeth has $11
David has $21
Step-by-step explanation:
let Miguel share be M
let Lisbeth share be L
let David share be D
from the question, we know that
M=3D
L=D-10.
M+L+D=95
thus,
3D+(D-10)+D= 95
3D+D-10+D= 95
5D-10 = 95
5D= 95+10
5D= 105
D= 105/5
D= 21.
thus,
M = 3D = 3×21
= $63
L = D-10 = 21-10
= $11
(63+21+11)$ = $95
Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape.
Answer:
Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]
Step-by-step explanation:
Total fabric available = 17 yards
fraction used = one-third = 1/3
Let us convert this fraction to actual number
He used one-third of total
= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]
To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:
The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2
[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]

If two angles are complements, then they are both acute. Which is the hypothesis?
Answer:
the hypothesis is "two angles are complements"
Step-by-step explanation:
In the given statement, the hypothesis is "two angles are complements".. While the conclusion is that "they are both acute".
The hypothesis of the two angles being complements is what led to the conclusion that they are both acute since sum of 2 complementary angles is 90° and acute angle is any angle that measures less than 90°.

Answer:
The system of equations will be:
p(x) = 0.9x + 6.80
m(x) = 0.65x + 7.30
Hence, option D is correct.
Step-by-step explanation:
The slope-intercept form of the linear equation
f(x) = mx+b
where
m is the rate of change or the slopeb is the y-interceptAnalyzing Papa's Pizzeria p function:
Given that A large pizza at Papa's Pizzeria cost $6.80 plus $0.90 for each topping.
Let p is the function of Papa's Pizzeria.As the fixed cost or initial cost of Papa's Pizzeria is $6.80.
Thus, the y-intercept b = 6.80As Papa's Pizzeria offers $0.90 for each topping.
Thus, the rate of change or slope m = 0.9We know that the slope-intercept form of the linear equation
f(x) = mx + b
In this case, the function is m.
now substituting m = 0.9 and b = 6.80 in the slope-intercept form of linear equation
p(x) = 0.9x + 6.80
Thus, the equation that represents the Papa's Pizzeria topping and cost model.
p(x) = 0.9x + 6.80
Analyzing Papa's Pizzeria p function:
Given that a large cheese pizza at Mama's Pizza costs $7.30 plus $0.65 for each topping.
Let m is the function of Mam's Pizzeria.As the fixed cost or initial cost of Mama's Pizza is $7.30.
Thus, the y-intercept b = 7.30As Mama's Pizza offers $0.65 for each topping.
Thus, the rate of change or slope m = 0.65We know that the slope-intercept form of the linear equation
f(x) = mx + b
In this case, the function is m.
now substituting m = 0.65 and b = 7.30 in the slope-intercept form of linear equation
m(x) = 0.65x + 7.30
Thus, the equation that represents the Mama's Pizza topping and cost model.
m(x) = 0.65x + 7.30
Conclusion:
The equation that represents the Papa's Pizzeria topping and cost model.
p(x) = 0.9x + 6.80
The equation that represents the Mama's Pizza topping and cost model.
m(x) = 0.65x + 7.30
Thus, the system of equations will be:
p(x) = 0.9x + 6.80
m(x) = 0.65x + 7.30
Hence, option D is correct.

Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x)=2(3x+4)(x^2+2)
Answer:
Step-by-step explanation:
The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).
How was this obtained. notice that if x = 0 then
f(0) = 2(3*0+4)(0^2 + 2)
f(0) = 2(4)(2)
f(0) = 16 just as the graph tells us.
