Answer: -16d³ + 3d² - 3d + 2
Step-by-step explanation:
Given expression
(4d - 6d³ + 3d²) - (10d³ + 7d - 2)
Expand parentheses
(REMEMBER to change [+, -] signs when there is a [-] sign in before)
=4d - 6d³ + 3d² - 10d³ - 7d + 2
Put like terms together
=-6d³ - 10d³ + 3d² + 4d - 7d + 2
Combine like terms
=(-6d³ - 10d³) + 3d² + (4d - 7d) + 2
=[tex]\boxed{-16d^3+3d^2-3d+2}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
-16d³ + 3d² -3d + 2
Step-by-step explanation:
(4d−6d³+3d²) − (10d³+7d−2) =
-6d³ - 10d³ + 3d² + 4d - 7d + 2 =
-16d³ + 3d² -3d + 2

find a rational number halfway in between the two numbers. 1/3 and 3/10
Answer:
39/60 is a rational number halfway b/w the given numbers.
Step-by-step explanation:
Add both of these numbers and then divide the result by 2.
(1/3+3/10)/2
=((30+9)/30)/2
=(39/30)*1/2
=39/60

Solve the compound inequality. Graph the solution
Answer: Choice B
Work Shown:
[tex]-2 \le 2x-4 < 4\\\\-2+4 \le 2x-4+4 < 4+4\ \text{ ... add 4 to all sides}\\\\2 \le 2x < 8\\\\2/2 \le 2x/2 < 8/2\ \text{ ... divide all sides by 2}\\\\1 \le x < 4\\\\[/tex]
This says that x is between 1 and 4; it can equal 1, but it can't equal 4.
To visually represent this, we'll have a closed circle at 1, an open circle at 4, with shading in between these circles. This is represented by graph B.

can someone explain to me how to do both of this question? tyvm
Answer: Hope this helps :)
Step-by-step explanation:
a) =Let the boys be x
girls = x-10
so
x + x - 10 = 50
or, 2x = 60
so, x = 30
boys = 30
girls = 30-10 = 20
Therefore, 30 boys participated in the activity.
b) = Let the zilong's stamp be x and miya's stamp be y
so
first
x+y = 40
y = 40-x
now
x - 10 = 2y
x-10 = 2(40-x)
x-10 = 80-2x
or, 3x = 90
so, x = 30
then y = 40-x
y = 40-30 = 10
Therefore, Zilong had 30 stamps and Miya had 10 stamps before.
Determine whether each function is one-to-one, onto, both, or neither.
===================================================
Explanation:
We see that the function passes the horizontal line test. It is impossible to draw a single horizontal line and have that horizontal line cross the curve at multiple points. It's similar to the vertical line test.
Since the curve passes the horizontal line test, that makes it one-to-one. Any y value is paired with a unique x value, and vice versa.
The function is also onto because we can generate any y value output we want. The curve extends forever upward and downward. The range is the set of all real numbers.
Therefore, the function is both one-to-one and onto.
---------------------
Extra info:
The term "injective" is the same as "one-to-one" The term "surjective" is the same as "onto"The term "bijective" is a combination of injective and surjective at the same timeWhat is the length of a rectangle with width 12in. and area 66in.²?
Answer:
5.5 inches
Step-by-step explanation:
Because Length * Width = Area, Length * 12 = 66.
If we solve for Length by dividing both sides by 12, we end up with Length = 5.5 inches

A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many inches of ribbon does the dressmaker have, in total?
Answer:
he can cut 60 strips or ribbon
Step-by-step explanation:
The dressmaker has 720 inches of ribbon
from each roll of ribbon, he can make 6 12-inch pieces or ribbon
she has 10 rolls
so 6(strips per roll) x 10(amount of rolls) = 60 strips :)

Write a rule for the geometric sequence with the given description. The first term is -3, and 5 is the previous term.
Answer:
The rule is (-3)(5)^(n-1).
Step-by-step explanation:
OK so the common ratio is 5 and first term = -3.
nth term = ar^(n-1)
= (-3)(5)^(n-1).

Hi,
Answer is $0.19
Step-by-step explanation:-
We know that:-
15 dimes = $1.50
20 nickels = $1.00
8 quarters = $2.00
half dollar = $0.50
19 pennies = $0.19
Total = $5.19
Since Billy spended $5, so,
$5.19 - $5 = $0.19
Hope it helps you...

Rearrange the formulae to make x the subject:
ay/x - dx= wx
Thanks in advance
Answer:
[tex] \frac{ay}{x} - dx = wx [/tex]
multiply x through out:
[tex]ay - {dx}^{2} = w {x}^{2} \\ {wx}^{2} + {dx}^{2} = ay[/tex]
factorise out x²:
[tex] {x}^{2} (w + d) = ay \\ {x}^{2} = \frac{ay}{w + d} [/tex]
take square root on both sides:
[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{ay}{w + d} } \\ \\ x = \sqrt{ \frac{ay}{w + d} } [/tex]
Step-by-step explanation:
the biggest obstacle is usually a division by x.
so, let's get rid of it by multiplying both sides of the equation by x
ay - dx² = wx²
then
ay = wx² + dx² = (w+d)x²
y = (w+d)x²/a = x² × (w+d)/a
