Answer:
X=9
Y=-9
Step-by-step explanation:
3x - 4y =9
-3x +2y=9 cross 3x and - 3x since they're opposite ــــــــــــــــــــــــ
-4y +2y =9 +9
-2y =18
Y =-18/2
Y= -9
Replace y in the first equation:
3x - 4 (-9)=9
3x +36=9
3x = 27
X= 27/3
X= 9
Hope this helps you.. Good luck
First off hmm <span>26°1' is just 26 degrees and 1 minute
there are 60 minutes in 1 degree, so 1minute is just 1/60 degrees
so </span>26°1' is 26° + (1/60)° or 26.1667 rounded up, since 1/60 is a recurring unit
alrite... so hmm, check the picture below
make sure your calculator is in Degree mode.
Answer:
The last one
Step-by-step explanation:
1/256 can only be a non fraction is the exponent is negative. but since the t is not also in the denominators the original two exponents must be negative so they times to a positive so:
(4t^-4) ^-7
(4^-7) (t^-4×-7)
(1/4^7) (t^28)
1/256 t^28
11
Step-by-step explanation:
first you add seven plus four and then you get your answer that is eleven

Step-by-step explanation:
B. A coordinate plane has an x axis from 0 to 5 in increments of 1 and a y axis from 0 to 5 in increments of 1. Point A (3,1) is plotted 3 units to the right and 1 unit above the origin. Point B (0,3) is plotted 3 units above the origin. Point C (1,3) is plotted 1 unit to the right and 3 units above the origin.
