You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
Answer:
(There's a confusion here, is x 2 x times 2? The answer and explanation are based on x multiply by 2)
y = -8
Step-by-step explanation:
Substitution Method-
y = x 2 - 4
x = -2
y = (-2) 2 - 4
PEMDAS - parentheses; exponents; Multiplication & Division; Addition & Subtraction
we are going to multipl -2 and 2 together ---> -4
y = -4 - 4
Same sign add, different sign subtract.
Same sign keep the sign, different sign keep the larger.
y = -8

Hope this helps!
Thank you,
Have a great day!
We know that area=0.5*base*height.
Thus, the equation would look like:
127.5=0.5*base*height
That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.
Answer:
x=3
Step-by-step explanation:
In(x-1) = In(6) - In(x)
In(x-1) + In(x) = In(6)
In((x-1)x) = In(6)
In(x^2-x) = In(6)
x^2-x=6
x^2-x-6=0
x^2+2x-3x-6=0
x(x+2)-3(x+2)=0
(x-3)(x+2)=0
x=3 because x=-2 need to be cancel out
