Answer:
A. 3/13
Step-by-step explanation:
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
Using the given points, this is ...
m = (-4 -(-1))/(-8 -5) = -3/-13 = 3/13

Answer:
1. Domain: -2, 0, 4; Range: -7, -1, 0, 3
2. Domain: -4, -1, 2, 3 Range: -5, 1, 8
Step-by-step explanation:
Domain and range are the just the x and y value in function table or ordered pair.
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.

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 recipe for lemonade calls for 6 cups of lemonade for every 24 cups water. Which equation can be used to find x, the percent of lemonade in the recipe? (HINT: think of how much total lemonade and water is being used) *
Answer:
To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total
TWO of the six are lemon 2/6 x 100 = 33.33% Lemon the rest is water 100-33.33= 66.67% water
OR
FOUR out of the SIX are water 4/6 x 100 = 66.67% Water

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.
Answer:
66.25

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.

Which equation represents the line that passes through the points (-3, 7) and (9,-1)? oy--3x+5 o y=-x-7 o y=zx-7 oy - 12 2x+5
Answer:
use the slope equation (y2-y1) / (x2 -x1). plug in values and solve
(-1 -7) / (9 -(-3)) (subtracting a negative is the same as adding a positive)
-8 / 12 (simplify)
m = -2/3
then, plug in one of the points and the slope into the slope-point equation.
(y - y1) = m (x - x1) (the point-slope form)
y - 7 = -2/3( x - (-3)) (plug in the slope and point 1 values, then solve)
y - 7 = -2/3x - 2 (add 7 to both sides)
y = 2/3x +5 (the answer)

(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

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.
Lix wants to by a shirt for $25. What is the total cost with a 4.1% sales tax? Round to NEAREST CENT.
Answer:
about $26.00
Step-by-step explanation:
$25/100 = 0.25 for 1%
1% times 4.1 = 1.025 in sales tax
plus 25 equals 26.025
round to the nearest cent = $26.00

Pablo folds a straw into a triangle with side lengths of 4x2-3 inches,4x2-2 inches, and 4x2-1 inches.Which expression can be used to find the perimeter of the triangle?
Answer:
The expression to find the perimeter is [tex]12x^2-6[/tex].
Step-by-step explanation:
Given: The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
To find: The expression that can be used to find the perimeter of the triangle.
Solution:
We have,
The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
We know that,
The perimeter of a triangle is sum of all the sides.
So, Perimeter [tex]=(4x^2-3)+(4x^2-2)+(4x^2-1)[/tex]
[tex]\implies \text{Perimeter}=12x^2-6[/tex]
Hence, the expression to find the perimeter is [tex]12x^2-6[/tex].

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
