Answer:
x = 15/7
Step-by-step explanation:
-7x - 3 = 12
-7x = 12 + 3
-7x = 15
x = 15/7

Number of units = x
(a) c(x)= $94000 + 11.2x
(b) r(x) = 16.98x
(c) p(x) = 16.98x - 11.2x - 94000
p(x) = 5.78x - 94000
Answer:
No. It is an obtuse triangle.
Step-by-step explanation:
If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.
Answer:
y = -
x + 3
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
, thus
y = -
x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 3 + c ⇒ c = 6 - 3 = 3
y = -
x + 3 ← equation of line
Answer:
x= - 13
Step-by-step explanation:
2(3x+6) = 3(x-9)
6x+12 = 3x -27
-3x -3x
3x+12=-27
-12 -12
3x= -39
/3 /3
x= - 13
