Answer:
A. 12 + 8x
B. x - 6 < 72
C. x - 5 = 2/3x
D. 2x : 14 or 2x/14
E. -9x + 3y - 3/2
Step-by-step explanation:
Answer:
see the attached graph
Step-by-step explanation:
When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).
x +3y = -3
Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:
x/(-3) +y/(-1) = 1
The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.
Answer:
The number is 2.26
Step-by-step explanation:
Let The given numbers be x
Now according to question :
x : 18 = x² - 5
I.e x = 18 × ( x² - 5 )
or, x = 18 × x² - 90
or, 18 x² - x - 90 = 0
Or, From quadratic equation , the value of x
x = 
Or, x = 
Or, x = 
So, x =
∴ x =
= 2.26
Hence The number is 2.26 Answer
