Answer:
x=2.5 or x=-4
Step-by-step explanation:
factorisation= factors:1, 2, 4, 5, 10, 20 (only the positive factors)
We will use the factors 4 and 5.
=(2x-5)(x+4)=0
2x-5=0 || x+4=0
2x=+5 || x=-4
x=2.5 or x=-4
Answer:
Step-by-step explanation:
The dashed vertical line indicates that -3 is not included so x is greater than -3. The diagonal line is solid indicating that it is included so y is greater than or equal to -4x/5 -2. So it is second answer.
(f o g)^-1 (5) means that you take f of g(x), f(g(x)), and then find the inverse of that function by switching the x and ys, and then solving the equation for x = 5
Answer:
x = -7
Step-by-step explanation:
To find the gradient you do change in y/change in x so...
-12 - 0
————- = -12/4 = -3
0 - - 4
