Step-by-step explanation:
Answer:
The graph move up 5.
Step-by-step explanation:
When we add a constant to the end of a parabola, it shifts the graph up and down. Since the constant here is positive, the graph moves up by that number (5)
Answer:
Hi there!
The correct answer is: 20
Step-by-step explanation:
knowing this a right triangle you can solve this problem in two ways
Method One: Pythagorean Theorem
a^2 + b^2 = c^2 then plug in the values
(12)^2 + (16)^2 = c^2 this will come out to be 400 = c^2
square root both sides and you get c = 20
Method Two: Pythagorean Identities
if you ever learned the Pythagorean identity 3,4,5
this triangle is indeed a 3,4,5 triangle it's just that each side is multiplied by the factor 4
so in this case since you know the missing side should be 5 you just multiply 5 by 4 and you get 20
Answer:
Last option; x < 2 and x > -1
Step-by-step explanation:
1. We know 2x − 1 < 3 and 2x − 1 > −3, so let's solve both of these inequalities.
2. (Solving for 1st condition)
Step 1: Add 1 to both sides.
Step 2: Divide both sides by 2.
3. (Solving for 2nd condition)
Step 1: Add 1 to both sides.
Step 2: Divide both sides by 2.
4. Now, we know that the value of x is greater than -1 but less than 2, and we can represent it on a number line like this:
