Answer:
m = -5
Step-by-step explanation:
Simplify both sides of the equation.
4(m−2)=2(m−9)
(4)(m)+(4)(−2)=(2)(m)+(2)(−9)(Distribute)
4m+−8=2m+−18
4m−8=2m−18
Subtract 2m from both sides.
4m−8−2m=2m−18−2m
2m−8=−18
Add 8 to both sides.
2m−8+8=−18+8
2m=−10
Divide both sides by 2.
2m/2 = -10/2
m = -5
Answer:
0.561
Step-by-step explanation:
To solve this problem we must resort to external information that I will leave attached with the answer, it is a table that for each value of n, gives us the critical values.
Returns the critical values for both the significant levels of 0.01 and 0.05.
If we go to the table we know that when n = 20 and the significant level is 0.01, the corresponding critical value is: 0.561
Answer:
x > -
or x > -2.4
Step-by-step explanation:
-9x > 9 + 3(-
x + 1) - 3x
-9x > 9 -x + 3 - 3x
-9x > 12 - 4x
-5x > 12
x > -
or x > -2.4
Quadratic is the y=2x^2
that is the parabola one
when will the exponential one be higher than the parabola?
that is, hmm, find the intersection points
we can see that x=1 is an intersection point
we see that it is between the intersection points
if we use our calculator
intsersect at x=-0.578621 and 1
so it is the one from -0.5 to 1
that is the 3rd option
-0.5≤x<1
