Answer:
x < 3
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
-2 • (x - 5) - 4 > 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
6 - 2x = -2 • (x - 3)
Equation at the end of step 3 :
-2 • (x - 3) > 0
Step 4 :
4.1 Divide both sides by -2
Remember to flip the inequality sign:
Solve Basic Inequality :
4.2 Add 3 to both sides
x < 3

Answer:
obtuse
Step-by-step explanation:
Answer:
A)
Step-by-step explanation:
To find the answer we must solve each of the systems separately. Starting with the first one:
x + y = 2
2x - y = 10
We must find what x or y is equal to and then replace it in the second equation. I'll go with y as it seems easier:
x + y = 2
y = 2 - x
Now that we found y we replace it in the second equation this way. Be careful with the signs, the minus with change our signs:
2x - (2 - x) = 10
2x - 2 + x = 10
3x = 12
x = 12/3
x = 4
Now that we have x, we replace the variable with its value in one of the equations. Again, for simplicity I'll go with the one that seems easier.
4 + y = 2
y = 2 - 4
y = - 2
Answer: C. 7/33
Step-by-step explanation: First you have to multiply 4/11 to the reciprocal of 12/7. After that you have to simplify 28/132 to 7/33
Answer:
A- 129.6 N
Step-by-step explanation:
Since the centrifugal force on the passenger, F varies jointly as the mass of the passenger, m and the square of the speed of the car,v. In mathematical notation, F ∝ mv² ⇒ F = kmv².
If F₁ = 226.8 Newtons, m₁ = 70 kilograms and speed v₁ = 60 kilometers per hour. From F= kmv², k = F/mv² the proportionality constant. If F₂ is the force on the passenger of mass m₂ = 90 kilograms and speed of car ,v₂ = 40 kilometers per hour. Then,
