Answer:
Terms must have the same variable (letter) and the same exponent (little number)
(7x² +3y+ 5) +(9x²+11y- 2)
Opening bracket
7x²+3y+5+9x²+11y-2
keeping like terms together
7x²+9x²+3y+11y+5-2
Since terms having same variable and exponent can be subtracted, added,divided and multiplied
So
Solving like terms we get
<u>16x²+14y+3</u> which is a correct answer.
Answer: 38.9
Step-by-step explanation:
Add all the numbers together and divide the sum by how many numbers there are.
Step-by-step explanation:
First put it in point slope for y = mx + b
y = -2x + 5
Now plug in what ever number you want for x and solve.
Answer:
if you want a t*-value for a 90% confidence interval when you have 9 degrees of freedom, go to the bottom of the table, find the column for 90%, and intersect it with the row for df = 9. This gives you a t*–value of 1.833 (rounded).
Step-by-step explanation:
Hope this helps!
-3
Because when u plug in x-value(0) in the graph the y=-3
