Write the equation of the line that passes through the points (7, –9)
and (1,-4). Put your answer in fully reduced point-slope form,
unless it is a vertical or horizontal line.
Answer:
y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
The equation of a line is y=mx+b
to find the equation of the line you need its gradient(m) and its y intercept(b)
the gradient is
[tex]\frac{y1-y2}{x1-x2}[/tex]
y1= the y value of the first point which is -9
y2=the y value of the second point which is -4
x1=the x value of the first point which is 7
x2=the x value of the first point which is 1
then input the values into the equation
[tex]\frac{(-9)-(-4)}{(7)-(1)}[/tex]
=[tex]\frac{-9+4}{6}[/tex]
=[tex]\frac{-5}{6}[/tex]
to find the y just times the x by the gradient and then minus it from the y
-9-(7 x [tex]\frac{-5}{6}[/tex])=14[tex]\frac{5}{6}[/tex]
making the equation y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
Is it possible to use dynamic geometry software to draw a triangle with
angles of 50°, 65°, and 70°? Explain.
Answer:
no
Step-by-step explanation:
The sum of the angles of a triangle must be equal to 180
50+65+70
185
This is not equal to 180 so it does not make a triangle

1. FIND THE AREA OF THE FIGURE.
plzz help meee.!.!.!
Answer:
The answer isn't there
Step-by-step explanation:
We can divide the figure into a rectangle and triangle and add the areas. The area of the rectangle would be length times width: 14 × 12 = 168. The area of a right angled triangle is [tex]\frac{ab}{2}[/tex], where a and b are both legs. a=12 and b=8, so the area would be [tex]\frac{12*8}{2}[/tex] which equals [tex]\frac{96}{2}[/tex], which is 48. Then we add both the areas, 168 + 48 = 216

sorry it isn’t real text but it’s because i couldn’t explain it well.. but pls help when you can!!
Answer and Step-by-step explanation:
10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.
The equations are:
Blank 1: 3x + 10
Blank 2: 2x + 20
To find when they are equal, we equal the equations together.
3x + 10 = 2x + 20
x = 10
Plug 10 into either equation and solve.
Blank 3: 10 (At 10 miles, the equations are equal)
Blank 4: $40 (The will equal $40)
I hope this helps!

A small business is looking for rectangular warehouses to store extra merchandise. Warehouse A has an area of 6900 ft2. Warehouse B is half as wide and one-third as long. How many square feet is Warehouse B?
Answer:
The area of the warehouse B is 1150 square feet.
Step-by-step explanation:
Let [tex]x[/tex], [tex]y[/tex] are the width and length of the warehouse A, in inches. The areas of the each warehouse are described below:
[tex]A_{A} = x\cdot y[/tex] (1)
[tex]A_{B} = \left(\frac{1}{2}\cdot x \right)\cdot \left(\frac{1}{3}\cdot y \right)[/tex] (2)
Where:
[tex]A_{A}[/tex] - Area of the warehouse A, in square inches.
[tex]A_{B}[/tex] - Area of the warehouse B, in square inches.
If we know that [tex]A_{A} = 6900\,ft^{2}[/tex], then by (1) and (2) we have the following equation:
[tex]A_{B} = \frac{1}{6}\cdot A_{A}[/tex]
[tex]A_{B} = 1150\,ft^{2}[/tex]
The area of the warehouse B is 1150 square feet.
Chloe is planning an event and purchasing floral arrangements. At Petals Plus, the arrangements cost $35.17 each, and the store
charges $67.00 for delivery of the flowers to the event site. At Blooms, the arrangements cost $25.03 each, and the store charges
$108.00 for delivery of the flowers to the event site.
How many arrangements should she purchase from Blooms in order to get a better value?
OA. 3
OB. 5
OC. 1
OD. 4
Answer: You would need at least 5 arrangements to make Blooms a better deal
Step-by-step explanation:
Petals Plus
y= 35.17x+67
Blooms
y= 25.03x+108
35.17x+67 =25.03x+108
10.14x= 41
x= 4.05
Convert 7x - y = -9 to slope-intercept form. Simplify your answer.
The equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9
Equation of a line in Slope-intercept FormIf "m" is the slope of a line and "b" is the y-intercept, the equation of the line in slope-intercept form is given as: y = mx + b.
Thus, given the equation, 7x - y = -9, rewrite/convert to slope-intercept form as follows:
7x - y = -9
-y = -7x - 9
Divide both sides by -1y = 7x + 9
Therefore, the equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9

Help i will give brainlist. The quotient of 2 and g is 8 can u pls show me step by step ty
Answer:
16
Step-by-step explanation:
Set up the equation: g/2 = 8
We want to get 'g' by itself, so we need to reverse the division of two. To do that, we multiply (division and multiplication go together, addition and subtraction go together) both sides by two (what you do to one side of an equation, you must do to the other).
End up with: g = 16

Mariela recolecto 625 mililitros de agua que gotea de su caño en 10 minutos, ella desea saber ¿cuanta agua gastara en una semana ?
Answer:
En una semana gastará 705,6 litros.
Step-by-step explanation:
Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.
10 min → 0,7 L
1440 min → x
x=(1440*0,7)/10
x=100,8 L
Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:
100,8*7=705,6 L
De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.
