Answer:
The solution is (-2,4)
Step-by-step explanation:
We'll solve the system
2x+5y=16
-5x-2y=2
using elimination by addition and subtraction.
Let's eliminate x first. To do this, multiply the first equation by 5 and multiply the second equation by 2. We get:
10x + 25y = 80
-10x - 4y = 4
----------------------
21y = 84. Thus, y = 84/21 = 4.
Subbing 4 for y in the second equation, we get
-5x -2(4) = 2, or
-8 - 2 = 5x, or
-10 = 5x. Thus, x = -10/5 = -2.
The solution is (-2,4)
Answer:
5859375
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= 
where r is the common ratio and the first term
here r = 
= 
= 
= 5 and = 3, hence
= 3 × 
= 5859375
Answer:
B.
Step-by-step explanation:
All you have to do is get the numbers from the triangle AUV and multiply them by 3/2.
12 * 3/2 = 18 
8
So we already know that the scale factor is not 3/2
It's 2/3 because since the triangle get smaller the scale factor has to be smaller than 1.
HOPE THIS HELPS YAA!
Answer:
A
Step-by-step explanation:
Use the equation and plug in each of the x values to check if the y's will be the same and for the y-intercept(-6), you could see that when x was 0, y was at negative 6.
