The graph of a linear function C(d) will shift 20 units left side if the total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is function C(d) = 15d + 30.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is given by the function:
C(d) = 15d + 30
The charge per day is $15. The setup fee increases by $20.
The new total cost T is given by the function
T(d) = C(d) + 20
Plug C(d) = 15d + 30 in the above function:
T(d) = 15d + 30 + 20
T(d) = 15d + 50
The graph of a linear function C(d) will shift 20 units left side.
Thus, the graph of a linear function C(d) will shift 20 units left side if the total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is function C(d) = 15d + 30.

Find the equation of the line that passes through point (7,5) and (-9,5)
Answer:
y = 5
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 9, 5)
m = [tex]\frac{5-5}{-9-7}[/tex] = [tex]\frac{0}{-16}[/tex] = 0
This means the line is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (7, 5) and (- 9, 5) with y- coordinates 5, thus

Trigonometry focuses on the ratios between sides and angles of right-angled triangles. Ratios are used to maintain relationships between quantities in scaled models or mathematical problems. Practicing these calculations aids in mental math and practical applications.
Explanation:
Practice Writing Trig Ratios
Trigonometry involves understanding the relationship between the angles and sides of right angled triangles. These trigonometric ratios, which include sine, cosine, and tangent, are essential in connecting angles to their respective side lengths. They are ratios and thus dimensionless, meaning they have no units. These calculations become easier with practice, allowing one to approximate and compute them mentally.
When dealing with practical problems, such as scaling distances for a model or building, it is common to write proportions to maintain the relationships between lengths and widths. For example, if you have a scale that says 1 inch on the model represents 10 feet in reality (inches/feet = 1/10), you would write a ratio that respects this scale. Similarly, if comparing areas, you would establish a ratio outlining how one area relates to the other based on their respective dimensions.
It is also valuable to familiarize oneself with the functions of a calculator by experimenting with various operations such as squaring, square roots, trigonometric functions, and logs. This helps in comprehending the interconnectedness of these mathematical concepts and their practical application.

Three coins are tossed. Each coin has a Head and a Tail. Find the probability of getting three tails. Write answers as a simplified FRACTION.
Your answer would be 1/8.
The probability for getting a tail one time would be 1/2 because there are only 2 sides of a coin. Since tossing one coin doesn't affect the outcome of tossing the other coins, the probability for getting a tail on all of the coins is 1/2 each. We want this to happen 3 times, so the answer would be 1/2 × 1/2 × 1/2 = 1/8.

What is a triangle?A triangle is a shape that has 3 sides and 3 angles
Check below on how to determine the triangle area
The coordinates are given as:
L = (1,-1)
M = (3,2)
N = (1,3)
Calculate the length of side NL using:
NL = √[(x2 -x1)^2 + (y2 - y1)^2]
So, we have:
NL = √[(1 -1)^2 + (3 + 1)^2]
NL = √16
NL = 4
The altitude MP is 2 units.
So, the area is:
Area = 0.5 * NL * MP
This gives
Area = 0.5 * 4 * 2
Evaluate the product
Area = 4
Hence, the area of the triangle is 4 square units

The number of dogs in a city is declining at a rate of about .08% each
year. If there were 3500 cats to begin with, how many will there be in 10
years?
Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :[tex]N(t)=N_0(1-r)^t[/tex]
Where N(t) = Remaining cats after t days
[tex]N_0[/tex] = Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years = [tex]3500(1-\frac{0.08}{100})^{10}=3472.100[/tex]
Hence There will be 3472 cats in 10 years
How would I find x, I know it's an isosceles triangle but I so not know how to solve for it?????
Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7[tex]\sqrt{2}[/tex] )^2
Add the left side
2x^2= 7^2 + [tex]\sqrt{2}[/tex]^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7

Saniya writes a positive integer on each edge of a square. She also writes at each vertex the product of the numbers on the two edges that meet at that vertex. The sum of the numbers at the vertices is 15. What is the sum of the numbers on the edges of the square?
To solve this problem, we first set up an equation to express the product of the numbers at the vertices of the square in terms of their sum. Then, we use this equation to find the values of the numbers on the edges of the square. The sum of all the numbers on the edges equals to 2 times the square root of 15.
Explanation:Let's denote the four numbers on the edges of the square as a, b, a, b (since it's a square, opposite sides are equal). The products at the vertices are: ab (top left), ab (top right), ab (bottom right) and ab (bottom left).
So the sum of these numbers at the vertices is 4ab = 15. From here, we can solve the equation for ab, giving us ab = 15 / 4.
The problem asks for the sum of the numbers on the edges, which equates to 2a + 2b. As due to our current setup, a = b, we can simplify this to 4a or 4b. But we don't have a or b - we have ab. Because of this, we require a bit of algebra. We know that (a + b)^2 = a^2 + 2ab + b^2. In our case, where a = b, this can simplify to 4a^2. From here, we proceed with ab = 15/4 to replace 2ab in the equation with the latter, and then solve for a^2, followed by a.
The result is a=root(15/4). To get the sum of all the edges, we would then multiply this by 4, giving us 4*root(15/4) = 2root(15).

The sum of the numbers on the sides of the square is calculated by doubling the number on the side 'a', adding to double the number of 'b'. With 'b' equals to 15 divided by four times 'a', the sums equals to 2a plus 2 times 15 divided by four times 'a'.
Explanation:Let's denote the numbers on the sides of the square as a, b, a, b, respectively. Hence, each vertex will be the product of a and b, making each vertex to be ab. Given that the total sum of these vertex is 15, we have 4ab = 15, which simplifies to ab = 15/4.
To find the total sum of the numbers on the sides of the square (the edges), we should sum up all a and b's. Therefore the sum will be 2a + 2b. Given that b = 15 / (4a), we can substitute b into the equation, simplifying to get the total sum = 2a + 2*(15 / (4a)). This is the solution to the problem.

Shannon bought 5 1/8 pounds of apples. Bill bought 2 7/8 pounds of apples. Which most
closely estimates how many more pounds of apples Shannon bought than Bill?
To find out how many more pounds of apples Shannon bought compared to Bill, subtract the weight of Bill's apples from the weight of Shannon's apples. The most close estimate of how many more pounds Shannon bought is 2 1/4 pounds.
Explanation:To find out how many more pounds of apples Shannon bought compared to Bill, we need to subtract the weight of Bill's apples from the weight of Shannon's apples.
Shannon bought 5 1/8 pounds of apples, which can be written as a mixed number as 5 + 1/8.
Bill bought 2 7/8 pounds of apples, which can be written as a mixed number as 2 + 7/8.
To subtract these mixed numbers, we can find a common denominator and then subtract the whole numbers and fractions separately.
Let's convert the mixed numbers into improper fractions and subtract:
Shannon's apples = 5 + 1/8 = 40/8 + 1/8 = 41/8Bill's apples = 2 + 7/8 = 16/8 + 7/8 = 23/8Shannon's apples - Bill's apples = 41/8 - 23/8 = (41 - 23)/8 = 18/8 = 9/4The most closely estimate of how many more pounds of apples Shannon bought than Bill is 9/4 pounds or 2 1/4 pounds.
