Plot y = -3x-3 (x = 0, y - -3, and x =1, y = - 6 ), as a *dashed* line (> means greater, not greater or equal than), then shade everything on top of that line.
Plot y = 4x+4 (x=0, y = 4, x = 1, y = 8) again as a dashed line, and shade everything above it.
Where both shades are on op of each other, both inequalities hold. This is the answer. Good luck plotting!
Step-by-step explanation:
4 (1 – 3x) + 4x = -100
4-12x+4x=-100
-12x+4x=-100-4
-8x=-104
x=-104/-8
x=13
Answer with explanation:
y= |x| -1
|x|=x , if x≥0
and = -x , if x<0.
So,the above function can be written as
First Drawing the graph of
y= x-1 for, x ≥ 0
And , then , y= -x -1 ,for x <0.
and then combining, the two we get.
Answer:
Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
I think the correct answer from the choices listed above is the first option. The equation (m + 5)(m - 9) = 0 has <span>solutions of m = -5 and m = 9. Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.</span>
