Answer:
a=2 , b= (-1)
Step-by-step explanation:
8a-4b=20/×(-2)
5a-8b=62
-16a+8b= -40
5a-8b=62
now -8+8=0 right? so the only parameter that we have is a.
-16a+5a= -40+62
11a = 22/(÷11)
a=2
in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.
8×2-4b=20
-4b=20-16
-4b=4/÷(-4)
b= -1
Answer:
A≈22 | B≈4.4 | C≈13.2
Step-by-step explanation:
5 + 1 + 3= 9
40/9≈ 4.444…
(4.4x5=22)+(1x4.4=4.4)+(3x4=13.2)= 39.6≈40
Idrk if I did this right, but I hope it’s kinda useful (I have a feeling I misunderstood the question lmdao)
Answer:
-31
Step-by-step explanation:
These numbers are categorized as numerical coefficients. A number that is next to a specific variable in an algebraic or polynomial expression and is essentially being multiplied to that variable.
Answer:
-9x² + 5x + 11
Step-by-step explanation:
-5x² + (-4x²) + 5x + 2 + 9
-9x² + 5x + 11
