The product of the function is 2x^2+ 5x - 3
We are to find the product of the functions x + 3 and 2x -1
let f(x) = x+ 3g(x) = 2x - 1Taking the product:
f(x)g(x) = (x+3)(2x -1)
f(x)g(x) = x(2x) - x(1) + 3(2x) + 3(-1)
f(x)g(x) = 2x^2 - x + 6x - 3
f(x)g(x) = 2x^2+ 5x - 3
Hence the product of the function is 2x^2+ 5x - 3

The amount of money they must have to be able to buy the items is Php958.25
if 1 pack of instant noodle costs Php 6.75, 20 packs of instant noodles will cost (6.75 * 20) = 135PhpIf sugar costs Php49.50/kg, then 2.5 kg of sugar will cost (2.5* 49.5) = Php123.75If Rice cost Php 35.05/kg, the cost of 15 kg of rice will be (15*35.05) = Php525.75If a pack of sardine cost Php19.25, 5 cans of sardines will cost Php96.25If a pack of coffee costs Php7.75, the cost of 10 small packs of coffee will be Php77.5
The amount of money that they must have is the sum of all the amount expressed as:
Total amount = Php135 + Php123.75 + Php525.75 + Php96.25 + Php77.5

Answer:
x
Step-by-step explanation:
Refer to '<' as ' less than or equal to '
Whenever you are deal with these types of inequalities / equations, nake sure to equate the denominators of both entities involved in the operation be it ( -, × , ÷ ,+ )
with that in mind
* 2x - 3/5 - x/3 < 2 has 2 different denominators i.e - 5 & 3
so to equate both sides, let's multiply each by the denominator they are lacking.
* 2x - 3/5 lacks 3 compared to -x/3.
* similarly, -x/3 lacks 5 compared to 2x - 3/5
multiply both by what they lack (2)
thus, (2x - 3 )×3 /(5) × 3 - (x × 5) × 5/ (3) × 5 < 2
* 6x - 9/ 15 - 5x/15 < 2
we can now combine the numerators since we now have a common denominator which is 15.
* 6x - 9 - 5x/ 15 < 2 (6x-9-5x) is equal to -9 + x = x - 9.

x2 + 14 x + 33 = 0
Answer:
-11, -3.
Step-by-step explanation:
x^2 + 14x + 33 =0
To factor this we need 2 numbers whose product is 33 and whose sum is 14 .
These are 3 and 11, so:
(x + 3)(x + 11) = 0
x = 11, -3.
Joseph earns a salary of $40 per day working at a pizza
restaurant. He earns an additional $3 for every delivery he makes.
Which function represents the amount of money, y, Joseph will earn in one day if he makes x deliveries?
A y = 3x + 40
B y = 3x - 40
C y = 40x + 3
Answer:
C
Step-by-step explanation:
40x + 3
Answer:
A y = 3x + 40
Step-by-step explanation:
He is paid $40 every day to you would add that number to the equation, then every time he makes a delivery, he makes an additional $3.
So, to find the amount of money he would make in one day your equation should look something like this
y = 3x + 40
y being that amount of money he makes in one day
3 being that amount of money he receives for every delivery
x being the number of deliveries he makes in one day
40 being that amount of money he makes in one day.

(b) 3 +x = 12
Step-by-step explanation:
To solve these for x, you would ...
a) divide by 3
b) subtract 3
c) add 3
d) multiply by 3
The subtraction property of equality says you can subtract the same value from both sides of an equation without affecting the value of the variable(s). It is applicable when you need to subtract a quantity in order to get the variable by itself.
Solving 3 +x = 12 would make use of the Subtraction Property.
A 9-foot roll of waxed paper costs $4.32. What is the price per inch?
The price per foot is $0.91
Step-by-step explanation:
A 6-yard roll of butcher paper costs 16.38
1 yard = 3 foot
6 yards = 3 times 6 = 18 foot
the cost of 18 foot is $16.38
To find price per foot, we divide the cost of 6 yards by 18
16.38÷ 18 = 0.91
The price per foot is $0.91
Pam works a 52 hours in a week. Considering that a normal work week is 40 hours and paid at $1470 per hour and overtime is paid at time and a quarter
What is her basic wage ?
How much is she paid in overtime wages? (SHOW WORK) *
What is her gross wage ?
Step-by-step explanation:
they way it is written, she has one of the best paying jobs in the world : $1470 per hour ...
but I guess it is really $14.70 per hour, right ?
that is then her basic wage : $14.70 per hour for 40 hours = 14.7 × 40 = $588.
her overtime rate is then 14.7×1.25 (one time and a quarter) = 18.375 ≈ $18.38
and she gets that rate for all hours beyond the basic 40 hours, so, 52-40 = 12 hours.
12×18.38 = $220.56
or if you need it totally precise
12×18.375 = $220.50
in total, her gross wage for that week is then
588 + 220.56 = $808.56
or totally precise with unrounded hourly rates
588 + 220.5 = $808.50
which would create a mean hourly rate
808.56/52 = $15.54923077... per hour ≈ $15.55 per hour
or
808.5/52 = $15.54807692... per hour ≈ $15.55 per hour
many payroll systems do the rounding of the hourly rates and then calculate the total amount (as the first option here). some others keep the full decimal positions in the calculation and then only round the total (as the second option here).
so, it is the question what your teacher expects here. I cannot tell from the description.
Write an equation of a line that is parallel to y = -3x + 5 and passes through (0, 3).
Answer in slope-intercept form
Answer:
A line parallel to this one would have a slope of 3. where m is the slope and b is the y intercept. In this case, the equation y=3x+5 is already in slope intercept form, which means the slope is 3. Parellel lines have the same slope, so any other line with slope 3 is parallel to this line.
I think that's the answer
Answer: y = -3x - 3
Step-by-step explanation:
If you are looking for a line that is parallel, then it must have the same gradient
Therefore;
y= -3x +c
And because it passes through (0,3), substitute in the values to find c
3 = -3 x 0 + c
c = 3
So the equations would be y = -3x -3
Given that Ax - 4x² + 3x² + 4 = (x² - 2x + 1)(2x² + B) + C(x-1) + D for all values of x, evaluate A, B, C and D. Hence, deduce the remainder when Ar-4x+3x²+4 is divided by 2x² + B.

f(x) = (x - 1) (4x + 3) (3x - 8) has zeros at x = 3/4, x= 1, and x = 8/3.
What is the sign of f on the interval - 3/4
Using the given roots, it is found that on the interval [tex]-\frac{3}{4} < x < 1[/tex], the function is positive.
The function is:
[tex]f(x) = (x - 1)(4x + 3)(3x - 8)[/tex]
The zeroes are:
[tex]x = -\frac{3}{4}, x = 1, x = \frac{8}{3}[/tex]
Between two zeroes, the function has the same sign, hence, to find the sign on the interval [tex]-\frac{3}{4} < x < 1[/tex], we find the numeric value of the function of a value of x on the interval, for example f(0), for x = 0.
Then:
[tex]f(0) = (0 - 1)[4(0) + 3][3(0) - 8] = (-1)(3)(-8) = 24[/tex]
Since f(0) is positive, the function is positive on the interval [tex]-\frac{3}{4} < x < 1[/tex].

Prism A and Prism B have the same volume. Which could be the dimensions of Prism B?
Prism A:
length = 8 feet
width = 4 feet
height = 5 feet Prism B:
length=? feet
width=? feet
height=? feet
Answer:
length = 20 ftwidth = 20 ftheight = 0.4 ftStep-by-step explanation:
The volume of Prism A is ...
V = LWH
V = (8 ft)(4 ft)(5 f) = 160 ft³
Any set of dimensions that have a product of 160 ft³ will give a prism with the same volume. You could have, for example, ...
length = 20 ft
width = 20 ft
height = 0.4 ft
Step-by-step explanation:
We know that
Volume of prism = lwh
=> 8 × 4 × 5
=> 32 × 5
=> 160 ft³
So,
The possible length, height and width could be
Length = 10 ft
Breadth = 8 ft
Height = 2 ft
