Which property of operation could you use to show whether 7y + 7b + 3y and 7(y x b) + 3b are equivalent or not
Answer and explanation:
They are not equivalent because if we simplify the second expression, the result isn't the same:
7(y×b)+3b
= 7(yb)+3b
=7yb + 3b
Therefore 7yb+3b≠7y+7b+3y
And even though you meant
7(y+b)+3b
=7y+7b+3b
=7y+10b
7y+10b≠10y+7b
What does 4×(-6) equal if you solve
Answer:
-24
Step-by-step explanation:
Since only one of the factors has a negative sign, the product will be negative.
4 · (-6) = -24
Answer:
-24
Step-by-step explanation:
4×(-6)
Remove parenthesis
-4 x 6
= -24
Extra
Its basically the same thing as 4 x 6 (which is 24) the only difference here is that the 4 is a negative.
POSITIVE FORM NEGATIVE FORM
4 x 6 = 24 -4 x 6 = -24
6 x 4 = 24 -6 x 4 = -24

648 flowers were arranged in 27 large vases, with the same number in each vase. How many flowers would be needed to fill 120 vases?
Answer: 2880 flowers
Step-by-step explanation:
Since 648 flowers were arranged in 27 large vases, with the same number in each vase, this means that each vase will contain 24 flowers
= 648/27
= 24 flowers
Therefore, the number of flowers needed to fill 120 vases will be:
= 24 × 120
= 2880 flowers
Show the solution for a two square room have a total floor area of 89m rise to power 2 one room is 3mlonger each way than the other find the dimensions of the two rooms
Answer:
side length of the smaller room = 5 m
Side length of the larger room = 8 m
Step-by-step explanation:
Total area of two square room = 89 m²
Area of a square = side²
Let
x = side of the smaller square
x + 3 = side of the longer square
Total area = area of room A + Area of room B
89 = x² + (x + 3)²
89 = x² + x² + 6x + 9
89 - 9 = 2x² + 6x
2x² + 6x = 80
2x² + 6x - 80 = 0
Divide through by 2
x² + 3x - 40 = 0
Solve quadratic equation using factorization method
x² + 8x - 5x - 40 = 0
x(x + 8) -5(x + 8) = 0
(x - 5) (x + 8) = 0
(x - 5) = 0 (x + 8) = 0
x = 5 x = -8
The side length of a square room can not be a negative value
Therefore, side length of the smaller room = 5 m
Side length of the larger room = 5 + 3
= 8 m

20 points! Write an exponential function in the form y=ab^x that goes through points (0, 8) and (2, 200)
Answer:
[tex]y=8(5)^x[/tex]
Step-by-step explanation:
We want an exponential function that goes through the two points (0, 8) and (2, 200).
Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:
[tex]8=a(b)^0[/tex]
Simplify:
[tex]a=8[/tex]
So we now have:
[tex]y = 8( b )^x[/tex]
Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:
[tex]200=8(b)^2[/tex]
Solve for b. Dividing both sides by 8 yields:
[tex]b^2=25[/tex]
Thus:
[tex]b=5[/tex]
Hence, our exponential function is:
[tex]y=8(5)^x[/tex]
Answer:
[tex]y = 8(5) {}^{x} [/tex]
Step-by-step explanation:
The normal exponential function is in form
[tex]y = ab {}^{x} [/tex]
let plug in 0,8
[tex]8 = ab {}^{0} [/tex]
b^0=1
so
[tex]8 = a \times 1 = \: \: \: \: a = 8[/tex]
So so far our equation is
[tex]y = 8b {}^{x} [/tex]
So now let plug in 2,200
[tex]200 = 8b {}^{2} [/tex]
Divide 8 by both sides and we get
[tex]25 = b {}^{2} [/tex]
[tex] \sqrt{25} [/tex]
Which equal 5 so b equal 5. So our equation is
[tex]y = 8(5) {}^{x} [/tex]

Which equation represents exponential decay?
Answer:
The answer is C
Step-by-step explanation:
Exponential decay is when b is between 0 and 1.
Answer:
C. y = 10(0.13)^x.
Step-by-step explanation:
exponential decay is decreasing from what I remember from Algebra 1 Honors. So therefore, your only answer can be C. y = 10(0.13)^x.
The others all increase because 31, 3.1, 1.03 are all bigger than 1 which means that they increase while .13 decreases.
C. y = 10(0.13)^x.

The area of a circle, in terms of pi, is 9 pi metres squared
Find the value of the radius.
Answer:
radius = 3
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here A = 9π , then
πr² = 9π ( divide both sides by π )
r² = 9 ( take the square root of both sides )
r = [tex]\sqrt{9}[/tex] = 3

Slope intercept form
Is the question complete??
The slope intercept form of the equation x + 6y - 2 is y = -x/6 + 1/3.
What is the slope intercept form of an equation ?When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.
Here m is slope and c is constant.
The given equation is,
x + 6y = 2,
To find the slope intercept form of the equation,
Solve the equation,
6y = -x + 2
y = -x/6 + 2/6

Khushali selects three different numbers from the set
{−7, −5, −3, −1, 0, 2, 4, 6, 8}. She then finds the product of the three chosen numbers. What is the largest product that Khushali can make?
Answer:
The answer i got is 192
Step-by-step explanation:
the largest numbers shown is 8,6 and 4. When you multiply all three of them you get 192
Answer:
280
Step-by-step explanation:
Through trial and error, one can figure out that the answer is 280. Now, you might first try to go 8 * 6 * 4, which equals 192. However, if you get the product of two negative numbers, it becomes a positive, which we can use. Using the numbers -7, -5 (which cancel out each other making the product positive), and 8, the product of all of them is 280. The largest product that Khushali can make is 280.
8 * 6 * 4 = 192
(-7) * (-5) * 8 = 35 * 8 = 280

Lamont has 30 books to pack in boxes . Each box holds 7 books. If he fills each box, how much books are left over ?
Answer:
B. 2
Step-by-step explanation:
To solve this, we need to divide 30 by 7. 30/7=4 R2
The remainder is 2, so there are 2 books left over.
Hope his helps and have an amazing day *^____^*
Answer:
2
Step-by-step explanation:
If 1 box holds 7 books...
2 boxes hold 14 books.
3 boxes hold 21 books.
4 boxes hold 28 books.
5 boxes hold 35 books.
However, since there are only 30 books, the 5th box won't be completely filled up. This gives us the answer: If Lamont fills up each box he would have 30-28, or 2 books left over.
