7 to 12 is actually already in the simplest form.
Answer:
(- 1, 3)
Step-by-step explanation:
To find the y- coordinate, substitute x = - 1 into the equation
y - 3 = 2(x + 1) ( add 3 to both sides )
y = 2(x + 1) + 3 ← substitute x = - 1
y = 2(- 1 + 1) + 3 = (2 × 0) + 3 = 0 + 3 = 3
Answer:
4 and 5
Step-by-step explanation:
n + 1 > 4
n > 4 - 1
n > 3
For the set { 1, 2 , 3 , 4, 5 }, 4 and 5 are greater than 3.
Hence, 4 and 5 makes the inequality n + 1 > 4 true.
Answer:
3x:4x for some real number x
Step-by-step explanation:
Since answer choices weren't provided, I generalized my answer.
First, notice we can simplify 6:4 into 3:2 because we can write the ratio as a fraction and simplify (6 and 4 are both multiples of 2).
Since 3 and 2 are relatively prime and the ratio cannot simplify anymore, we can say that the ratio of 6:4 = 3:2 = 3x:2x for some real number x because we can see that 3x:2x = 3:2 by simplifying (3x and 3 are both multiples of x).
As long as the answer choice you choose matches the format above, you should be correct! I hope this helps! :)
Use Pythagorean theorem
A^2 + B^2 = C^2
12^2 + B^2 = 15^2
