Pretend the equation was 2x - 4 > 8
The first step (of the two) would be to add 4 to the (-4) and to the other side of the equation (+4) to the 8, first. (You wouldn't use the number with variable in the first step) Then you would rewrite the equation: 2x > 12 (it's now 12 because you added the 4 to the 8). The second step is to divide 2x by 2x and do the same with 12. By dividing both sides with the coefficient, will help find "x". 12/2 is 6, therefore x > 6. (the last step would be to graph the expression if needed to)

Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2
Then the magnitude of the angle between the vectors is ...
arctan(2) ≈ 63.43°
Answer:
37.5 miles
Step-by-step explanation:
We can find the rate of conversion by dividing kilometers by miles. 5÷8=1.6, so 1.6 km = 1 mile. Now we can divide 60 by 1.6 to find miles.
Hope this helped!
Answer:h=-2
Step-by-step explanation:
Equation:h(-6) = |2(-6) +1| +1
Step 1: Simplify
=-6h=12
Step 2:Divide both sides of the equation by -6
-6h/-6=12/-6
h=-2
You either multiply 2 x 2 or you add two on all sides and add them but I think you're supposed to multiply them
