Answer:
9 days
Step-by-step explanation:
32-2-2-2-2-2-2-2-2-2 = 14
The equation that represents the day, d, when there are 14 cookies in the jar will be 14 = 32 - 2d, and that day will be on the 9th day.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given,
Initial cookie = 32
Since each day 2 cookies are eaten so after "d" days the total eaten cookies will be 2d.
Remaining cookies = initial cookies - eaten cookies
Remaining cookies = 32 - 2d
The day when 14 cookies remain will be,
14 = 32 - 2d
2d = 32 - 14
d = 9
Hence "The equation that represents the day, d, when there are 14 cookies in the jar will be 14 = 32 - 2d, and that day will be on the 9th day".

What must you subtract from the expression –5x – 8 in order to make it equivalent to –9x – 1 for all values of x?
Answer:
the number is 4x - 7
Step-by-step explanation:
Let P be subtracted from -5x - 8 to make it equivalent to -9x - 1.
-5x - 8 - P = -9x - 1
make "-P" the subject of the formula
-P = -9x - 1 + 5x + 8
Collect like terms;
-P = -9x + 5x - 1 + 8
-P = -4x + 7
divide through by "-1"
P = 4x - 7
Therefore, the number that must be subtracted from -5x - 8 to make it equivalent to -9x - 1 is 4x - 7

Which expression is a factor of 36x2−9?
6x−9
18x−9
6x−3
18x−3
Answer:
C
Step-by-step explanation:
Comment
This is called the difference of squares. Both sides of the minus sigh must be perfect squares or able to be factored in such a way that you are left with perfect squares. 36x^2 is a perfect square. If you take its square root, you get √36x^2 or 6x. That makes B and D incorrect. So what about A and C?
A:The left side of 36x^2 is correct, but the right side is not. The left side of 36x^2 has a square root of 6x.
The right side has been left alone and it shouldn't be.
The 9 is a perfect square. Its square root is 3. That makes C the answer.
Is 1 + 4(3x – 10) – 12x equivalent to -9?
Answer:
No.

Combine like terms:
-39+0x = -39. -39 is NOT equal to -9.
Describe the steps necessary to solve the following system equations:
-3x - 4y = 2 and 3x + 3y = -3
Answer:
(- 2, 1 )
Step-by-step explanation:
Given the 2 equations
- 3x - 4y = 2 → (1)
3x + 3y = - 3 → (2)
Adding the 2 equations term by term will eliminate the x- term, that is
0 - y = - 1
- y = - 1 ( multiply both sides by - 1 )
y = 1
Substitute y = 1 into either of the 2 equations and solve for x
Substituting into (2)
3x + 3(1) = - 3
3x + 3 = - 3 ( subtract 3 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
solution is (- 2, 1 )
Answer:
x = -2 and y = 1
Step-by-step explanation:
3x + 3y = -3, x + y = -1, x = -y -1
-3(-y-1) - 4y = 2, 3y + 3 - 4y - 2 = 0
-y +1 = 0, y = 1
x + y = -1, x + 1 = -1, x = -2

Choose the graph that represents the figure and classify it. Then find the area.
D(-1, -1), E(-1, 3), F(2, 4), G(2, -3)
Answer:
Trapezoid with the area 16.5 unit²Step-by-step explanation:
Plotted the given points to find out the figure is trapezoid.
Area formula for trapezoid:
A = 1/2(b₁ + b₂)hThe length of the bases:
b₁ = DE = 3 - (-1) = 4b₂ = FG = 4 - (-3) = 7h is the horizontal distance between the bases:
h = 2 - (-1) = 3The area is:
A = 1/2(4 + 7)(3) = 16.5 unit²What is 3/8 simplified and divided please show steps
Answer:
0.375
cannot be simplified more.
Step-by-step explanation:
three is prime, meaning it can only be divided by 1 and itself. When you see a prime in a fraction, you cannot simplify anymore without accidentally making it more complicated. Divided would just be the decimal form. The decimal form of 1/8 is 0.125, so if you multiply it by three you should get 3/8=0.375
Calculus. Find the area.
Answer:
8/3 square units.
Step-by-step explanation:
First, visualize the area. You can refer to the attachment below.
To find the area then, we will integrate y from x = 0 to x = 2. Therefore:
[tex]\displaystyle A=\int_0^2x^2\, dx[/tex]
Integrate:
[tex]\displaystyle A=\frac{1}{3}x^3\Big|_{0}^2[/tex]
Evaluate:
[tex]\displaystyle A=\frac{1}{3}[2^3-0^3]=\frac{1}{3}(8)=\frac{8}{3}[/tex]
The area is 8/3 square units.
Answer:
A = [tex]\frac{8}{3}[/tex] units²

Which costs more per issue, 18-issue subscription for $40.50 or a 12-issue subscription for $33.60?
Answer:
12-issue subscription
Step-by-step explanation:
18-issue sub = $40.50 ÷ 18 = $2.25/issue
12-issue sub = $33.60 ÷ 12 = $2.8/tissue
=> The 12-issue subscription costs more per issue (2.8 > 2.25)
Answer:
so you would divide the cost by the issue
the 18 issue is $2.25 per issue
the 12 issue is $2.80 per issue
the 12 issue costs more
Determine the intercepts of the line:
y = -9x - 14
Answer: (-14/9, -14) or (-1.5, -14)
Step-by-step explanation:
y = -9x - 14
the coefficient without a variable in a slope-intercept equation is the y-intercept -- in this case, it is -14
to find the x intercept you use the equation given, set y to equal zero and Solve for x
- Your new equation should be: 0 = -9x - 14
Our new goal is to isolate the x
Start by doing the inverse of the coefficient, so add 14 to both sides
- Your new equation should be: 14 = -9x
Theres still a -9 attached to the x and the -9 is attached by multiplication -- so now you do the inverse function and divide both sides by -9
Your final answer: -14/9 = x or -1.5 with a repeating decimal
The table shows two linear functions and the function values for different values of x.

Answer:
B.) 20 degrees
Step-by-step explanation:
We know that the sum of angles in a triangle is equal to 180, so we can say that 80 + 4x + x is equal to 180. This means that 5x is 100 degrees, meaning that x = 20 degrees. The option with this answer is B.).
Answer:
The answer is B.
Step-by-step explanation:
4 × 20 = 80
80 + 80 = 160
A triangle is 180°
Find the missing x.
180 - 160 = 20
Plug 20 in for both x's to check your work.

A store sells a box of breakfast cereal for $3. Write an equation to relate the number of boxes b to total sales T.
Answer:
b = T / $3
T = $3b
Step-by-step explanation:
Given that:
Cost per box of cereal = $3
Total amount from sale of cereal = T
Number of boxes sold = b
Number of boxes sold = (Total amount from sale of cereal / cost per box)
Number of boxes (b) = T / $3
T = $3b
