Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8
Answer:
D
Step-by-step explanation:
It's these shapes because:
Rectangle- A quadrilateral with 2 pairs of congruent sides and only 90° angles is a rectangle.
Parallelogram- A quadrilateral with 2 pairs of parallel sides is a parallelogram.
I’ll explain part A and you can apply it to the other parts. The functions f(x), g(x), and m(x) are all equivalent to the given polynomials. So when it asks for f(x) + [g(x) - m(x)] you plug them in. The answer to Part A is 3x^2 +5x - z + [5x^2-3x+z - 2x^2 - 2x]. Combine the like terms (3x^2+5x^2-2x^2 = 6x^2 (because 3+5-2=6)) and so on until you’ve simplified it as much as possible!
Hello.
-50 <7k +6
-56 < 7k
-8 < k
k > -8 Your first answer is done.
7k +6 <-8
7k<-14
k < -2 There's your second answer.
For graphing, remember these rules:
1). Left to right-- Smaller to bigger numbers.
2). < or > is an unfilled/ empty dot.
3). greater than or equal/ less than or equal to is a filled dot.
