1. By combining like terms
2. Same variable = same term, so you can combine them
3. Because 2y - y = 1y , and 1y is the same as y because a y is one y (obviously)
4. 1/2 + 1/2 = 1. A half an x and a half an x makes one whole x, therefore, x
5. No. You solve them like you would a normal equation with like terms. So it would be 3z^2
Hopefully these are right, I’m a bit rusty!
6. 4x
7. 3y
8. y - 4.5
9. 3.5x + 2
10. 4y + 2
11. 7x
12. 2.2w - 0.5
13. 23b + 6.6
14. 3.75x + 1.5
15. 0.8x + 2.1
Good luck, I hope this helped
Answer:
n
Step-by-step explanation:
While you did not specify the equation, there are n roots for an equation of n power.
i.e. anything that x, power is 1, only one root
For
, there are two roots
For
, there are n roots
Answer:
10(5v-6)
Step-by-step explanation:
Answer:
NOT the graph A and the graph B.
Step-by-step explanation:
y = mx + b
m - slope
b - y-integer
If m > 0 then the function is increasing.
if m < 0 then the function is decreasing.
We have y = -2x + 3
m = -2 < 0 the function is decreasing
b = 3 y-intercept = 3
The x-intercept: y = 0. Substitute
0 = -2x + 3 add 2x to both sides
2x = 3 divide both sides by 2
x = 1.5
Therefore your answer is C or D (look at the picture)
Answer:
The range is 3.
Step-by-step explanation: To find the range you have to subtract the largest data number from the smallest data number. The highest is 3 and the lowest is 2. 3-2 is 1.
