Answer:
5
Step-by-step explanation:
Let x be that number.
4 + 3 × x = 19
4 + 3x = 19
Add -4 on both sides.
4 + 3x - 4 = 19 - 4
3x = 15
Divide both sides by 3.
(3x)/3 = 15/3
x = 5
Answer:
5.3x - 4 .
Step-by-step explanation:
(6.7x -3) - (3.4x - 1) + (2x - 2)
1. using the commutative property:
= 6.7x - 3 + 2x - 2 - (3.4x - 1) (we can remove the parentheses around the first 2 groups because they are added).
2. Using the distributive property on the last group:
= 6.7x - 3 + 2x - 2 - 3.4x + 1 (distributing the negative over the parentheses).
3. Now adding like terms we get:
5.3x - 4 (answer).
we have the equation

Remember that
If an ordered pair is on the graph of the given function, then the ordered pair must satisfy the given function
Verify each option
N 1
(0,1)
x=0, y=1
Is not true, because the log of zero is undefined
N 2
(1,1/2)
x=1, y=1/2
Is not true, because the log of 1 is zero
N 3
(1/2,1)

Is true
therefore
<h2>The answer is (1/2,1)</h2>
Its 1/2 because the triangle is spit in half so 1/2 is half of 2 and it's already simplifed
