The best decimal equivalent is 10/16
A because because you multiply 5 times 14 and that gives you 70
Answer:
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span>x−3</span>2</span></span>
Explanation:
Follow the steps:
<span><span>f<span>(x)</span></span>=2x+3</span>
1- replace <span><span>f<span>(x)</span></span> with y →y=2x+3</span>
2- simply switch <span>x and</span> so the equation looks like <span>x=2y+3</span>
3- use algebra to solve<span> for y</span>. (isolate y)
<span>x=2y+3</span>
<span>x−3=2y</span>
<span><span><span>x−3</span>2</span>=y</span>
This is the inverse function and is written as
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span><span>x−3</span>2</span></span></span>
If you are asking for the perimeter of the bulletin board the answer below will be correct!
Answer:
Square option: 9.5 Meters
Rectangle option: see explanation below
Step-by-step explanation:
To find the perimeter you must add the lengths of all the sides. Assuming the bulletin board is a SQUARE all four sides are going to be equal. Therefore you can divide 38 by 4 to get the length of one side (aka 9.5 meters).
Assuming the bulletin board is a RECTANGLE changes things up. You can pretty much pick any combination of numbers that will add up to 19 (because if it is a rectangle there are two pairs of equal side lengths). You could do 1 + 18, 5+14, 8+11. The options are really endless
Answer:
Step-by-step explanation:
Given that
S(x) stand for "x is smart".
Y(x) stand for "y is young".
C(x) stand for "x is a CS Major"
1) All CS majors are smart : C(x) ⇒ S(x)
2) Some CS majors are smart and not young.: There exists a∈C(x) such that a ∉ Y(x)
3) No young college students are CS majors.: ~Y(s)⇒CS(x)
