2x+8=20
2x=20-8
2x=12
12/2=x
6=x
Answer:
Q1 d, Q2 c, Q3 d
Step-by-step explanation:
Q1
g(x)=-3x+1
g(x)=16 means that
-3x+1=16 subtract 1 from both sides
-3x=16-1 combine like terms and divide both sides by -3
x=-15/3=-5
Q2
g(x)=3x²+4x-1
g(2) means that x=2 so substitute
g(2)=3*2²+4*2-1=12+8-1=19
Q3
domain are the x values
range are the y values
Step-by-step explanation:
-3 (4a-5b)
=-3×4a -(-3×5b)
=-12a+15b
Answer:
275.
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly. Therefore, since the only number is 275, the answer is 275, as 275 divides into 275 (1).
Gcf refers to a digit which can divide both numbers without a remainder
20|50 is divisible by 2 to become 10|25 and then divisible by 5 to become 2|5
=2×5
Gcf= 10
