Answer:
y - 1 = - 4(x + 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 3, 1), hence
y - 1 = - 4(x - (- 3)), thus
y - 1 = - 4(x + 3) ← in point- slope form
I think this a linear function. The graph has a constant flow of going up. In other words, it is linear.
Answer:
The volume of the gas is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
v------> the volume of a gas in cubic centimeters
p-----> the pressure of the gas in liters per square centimeters
so

we have

substitute and solve for k

The equation is 
<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>
so
For
Find the value of v
substitute in the equation


Answer:
Ur question is wrong..
Step-by-step explanation:
In a survey of 100 people, 60 like farming and 65 like civil service?
<u>60+65=125</u>..?
2x =50 since it is an isosceles triangle
x =25
the sum of all angles in a triangle is 180
5y + 10 + 50 + 2x=180
5y + 10 + 50 +50 =180 because 2x = 50
combine like terms
5y +110 = 180
subtract 110 from each side
5y = 70
y = 14
