To figure out a special number, Tammi’s mother was supposed to double her age and then add 4. Instead, Tammi’s mother added 4 to her age and then doubled that number. Tammi’s mother thought the special number was 80. What was the special number supposed to be?
Answer:
Step-by-step explanation:
36 plus 4 x 2 = 80 what her mom got but it’s 76 because 36x2 is 72 and 72 plus 4 is 76.

What is the result of subtracting the second equation from the first?
x−3y=6
−8x−y=6
Answer:
9x - 2y = 0
Step-by-step explanation:
Given
x - 3y = 6 → (1)
- 8x - y = 6 → (2)
Subtracting (2) from (1) term by term gives
x - (- 8y) - 3y - (- y) = 6 - 6 , that is
x + 8y - 3y + y = 0
9x - 2y = 0

A landscaper needs to fill a path measuring 2 feet by 6 feet with patio stones.
The patio stones are ench 1 foot by 2 feet, so the landscaper calculates that she
will need 6 of them,
Before arranging the patio stones, the landscaper wants to look at all of her
options. She cannot cut or overlap the stones, and they all must fit inside the
path area without any gaps. Two possible arrangements of the stones are shown
below. How many different arrangements are there in total?

We can say that the y intercept is at the location (0,-1)
This is where the graph crosses the vertical y axis. This is 1 unit below the origin.
This is assuming each tickmark on the grid represents 1 unit.
Answer:
The y- intercept is (0,-1)
Step-by-step explanation:
A y- intercept is when a point intercepts (crosses) the y- axis. Since the dot does not cross the x- axis, that point will be 0. It is below the y- axis, meaning it will be -1.
A company claims that their new bottle holds 25% more laundry soap. If their original container held 80 fluid ounces of soap, how much does the new container hold?
Answer: The new container folds 100 fluid ounces.
Step-by-step explanation:
Given: A company claims that their new bottle holds 25% more laundry soap.
If original container hold 80 fluid ounces.
Then, Quantity of soap in the new container = 80 fluid ounces + 25% of 80 fluid ounces
= [80+0.25 x 800] fluid ounces [ 25% = 0.25]
= 80+ 20= 100 fluid ounces
Hence, the new container folds 100 fluid ounces.

Uncle K takes one ball from the bag. Find the probability
that the ball is:
Red
Yellow
Blue
Red or yellow
Answer:
The probability that the ball is:
Red - 20:60 (simplified is 1:3)
Yellow - 15:60 (simplified is 1:4)
Blue - 25:60 (simplified is 5:12)
Red or yellow - 35:60 (simplified is 7:12)
2. Use the Pythagorean Theorem to find x.
9.2
16.5
Your answer
Answer:
The value of x = 13.7.
Step-by-step explanation:
Given
Hypotenuse = c = 16.5
a = 9.2
To determine
x = b ?
For a right-angled triangle with sides a, and b the hypotenuse is defined as
[tex]c=\sqrt{a^2+b^2}[/tex]
In our case, we have to get x
[tex]b=\sqrt{c^2-a^2}[/tex]
so substituting b = x, c = 16.5, a = 9.2
[tex]x=\sqrt{16.5^2-9.2^2}[/tex]
[tex]x=13.7[/tex]
Therefore, the value of x = 13.7.

(04.03 LC) Identify the domain of the exponential function shown in the following graph: (2 points) 5 4 2 TI y = 10 3 4 -5 -4 -3 -2 -1 all real numbers all positive numbers 1
Answer:
The domain is all real number:
i.e.
[tex]-\infty \:<x<\infty \:[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
y = 10ˣ
Determining the domain of the function y = 10ˣ :
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.From the graph, it is clear that the function has no undefine points nor domain constraints.
Thus, the domain is all real number:
i.e.
[tex]-\infty \:<x<\infty \:[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Answer:
The domain is all real numbers

Answer:
a). x = 10.20 in
b). x = 2.24
Step-by-step explanation:
a). By applying Pythagoras theorem in the given right angle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(15)² = x² + (11)²
225 = x² + 121
x² = 225 - 121
x² = 104
x = √104
x = 10.198 ≈ 10.20 in
b). By applying Pythagoras theorem,
(3x)² = (2x)² + (5)²
9x² = 4x² + 25
9x² - 4x² = 25
5x² = 25
x² = 5
x = √5 = 2.24
