Answer:
4: 60x + 12
Step-by-step explanation:
The amount that she earns in a day is fixed, and already known, so no need to make a coefficient with that term. But, we dont know how much phones she would sell in one day, as that is not limited. Hence, making the variable the amount of phone's she sells, multiplied by 60, as she makes $60 per phone that she cells.
y= 60x+12
Which of the following functions best represents the graph
Step-by-step explanation:
The zeroes of f(x) are -2, -3 and 2.
Hence f(x) = (x + 2)(x + 3)(x - 2) = (x + 3)(x² - 4) = x³ + 3x² - 4x - 12.
A clothing shop is offering a 12 percent discount for senior citizens. Which equation represents the discount price?
discount price = 1 - (original price)(0.88)
discount price = (original price)(1 – 0.12)
discount price = (original price)(0.12)
discount price = 1 – (original price)(0.12)
The equation of the discount is (b) discount price = (original price)(1 – 0.12)
How to determine the discount price?The discount is given as:
Discount = 12%
The equation of the discount price is then calculated as:
discount price = (original price)(1 – discount)
This gives
discount price = (original price)(1 – 12%)
Express 12% as 0.12
discount price = (original price)(1 – 0.12)
Hence, the equation of the discount is (b) discount price = (original price)(1 – 0.12)

a pool which is a right rectangular prism is partially filled with water the length and width of the pool is 30m and 8m the volume of the water in the pool is 70m what is the height of the water
Answer:
The height of the pool = 0.292 m
Step-by-step explanation:
For a right rectangular prism;
V = w*h*l
where; length (l) = 30 m
width (w) = 8 m
The volume v = 70 m
Thus; from V = w*h*l
The height of the pool = [tex]\dfrac{V}{wl}[/tex]
The height of the pool = [tex]\dfrac{70}{30*8}[/tex]
The height of the pool = 0.292 m

What is the slope of the line that passes through the points (−4,−2) and (−4,−22)? Write your answer in simplest form.
Answer:
Undefined Slope
Step-by-step explanation:
If we look at the points given, then we can see that the X coordinates are the same. Putting this into (y2-y1)/(x2-x1), we can see that the denominator would be 0, meaning the slope would be undefined.
Answer:
undefined
Step-by-step explanation:
1) y₂-y₁/x₂-x₁
2)-22 -(-2)/ -4 -(-4)
3) -20/0
4) slope is undefined so there is only one line (same x coordinate)

4/5 + 3/15 - 2/3 =
Answer:
Simplified Answer: 1/3 Non-Simplified Answer: 5/15
Step-by-step explanation:
Make every fraction have a common denominator:
4/5 * 3/3 = 12/15
3/15 = 3/15
2/3 * 5/5 = 10/15
Add and/or Subtract the numerator(s):
12 + 3 = 15
15 - 10 = 5
Place the final numerator over the denominator (Non-simplified Answer):
5/15
Simplify (What can you divide the numerator and the denominator by to make the fraction into it's simplest from without any remainders?):
5 goes into both 5 and 15.
5/15 divided by 5 = 1/3
Simplified Answer:
1/3
Dibuja un segmento de 6cm y su mediatriz construye un triángulo con dos de sus vértices en los extremos del segmento y el tercer vértice sobre la mediatriz ¿qué tipo de triángulo es?
Answer:
Equilátero si todos sus lados son iguales o isósceles si la base es menor que sus otros dos lados.
Step-by-step explanation:
Revisar fotografía adjunta.
Comienzas dibujando la línea de 6 cm. Luego encuentras su mediatríz, la cual está a 3 centímetros de cualquier extremo de la línea.
Luego dibujas el triángulo como se muestra en el dibujo. Dependiendo de la longitud de los lados, el triángulo podría ser equilátero si todos sus lados son iguales o isósceles si solo los dos lados inclinados son iguales y la base es diferente.
what is the y- intercept of a line that passes through the point (1,-7) and (5, -25)
Answer:
-32 I THINK
Step-by-step explanation:
The y-intercept of the line passing through the given points is -5/2.
What is y-intercept?An intercept is a point on the y-axis, through which the slope of the line passes.
Given that, a line that passes through the point (1,-7) and (5, -25)
The equation of a line passing through two points is given by,
y-y1 = (y2-y1)/(x2-x1)(x-x1)
y+7 = -18/4(x-1)
y+7 = -9/2x+9/2
y = -9/2x+9/2-7
y = -9/2x-5/2
Hence, The y-intercept of the line passing through the given points is -5/2.

find the area and height of a triangle 20cm 20cm 14cm
Answer:
A = 131.145 cm^2
Step-by-step explanation:
For this problem, we can see that this is an isosceles triangle. This can be observed from two equal lengths. Using this, let's apply the formula for the area of a triangle.
A = ( 1/2 ) * b * h
Note, we can say the base, b, is equal to 14 cm. We simply need to find the height. Using the idea of splitting the triangle into two right triangles, we can say the following based on the pythagorean theorem:
20^2 = (14 / 2)^2 + h^2
400 = 49 + h^2
400 - 49 = h^2
351 = h^2
18.735 = h
A = ( 1/2 ) * 14cm * 18.735cm
A = 131.145 cm^2
Hence, we have found the area of the triangle.

Answer:
The ratio of side lengths is 4:15
The ratio of areas as a fraction is 16/225
Step-by-step explanation:
We can probably assume the triangles are similar. If that is the case, the smaller triangle is 4/15s the size of the blue triangle. That makes the ratio 4:15.
As for the ratio of areas, areas are expressed in length^2. Inches squared, centimeters squared, meters squared, or whatever length. It is always a length squared.
Similarly, the ratio of the length can be squared to give the ratio of the areas. The ratio of the areas is 4^2 / 15^2 = 16/225
