Answer:
Step-by-step explanation:
2x - 5 = 15
Bringing like terms on one side
2x = 15 + 5
2x = 20
Option B is the correct answer
32. given (0,3)
fond slope by formula y2-y1/x2-x1 with any two points in the table ( you are lucky to be able to use formula in this equation!!) 5.3-3/1-0
2.3/1= 2.3 is slope you are able to check if this is true by doing it with every (x,y) point they give you.. luckyly the slope holds true for all the equation is
y=2.3x+3
33. this one the way I did it was plugging in (x,y) onto each equation and see of any hold true
y=4x+2.1
y=4x^2+2.1
y=2.1×4^x
y=4x
Let's plug in (1,8.4)
8.4=4 (1)+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=4 (1)^2+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=2.1×4^1 (1)
8.4=2.1×4
8.4=8.4 TRUE
8.4=4 (1)
8.4=4 not true
Answer:
4
+ 10
- 2y³ - 5y²
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
2y²(2y³ + 5y²) - 1(2y³ + 5y²) ← distribute both parenthesis
= 4 + 10 - 2y³ - 5y²
