Answer:
B: y= 3(1/3)^x
Step-by-step explanation:
I graphed it on Desmos
If you plug in the x and y, you get
7(1)(3)
7 x 1 x 3 = 21, so the answer is 21
Answer:
x = 2
y = -8
Step-by-step explanation:
9x−2y=34 -------------------(I)
5x+2y=−6 -------------------(II)
Add equation (I) & (II) and so y will be eliminated and we could find the value of x.
(I) 9x - 2y = 34
(II) <u>5x + 2y = -6</u> {add}
14x = 28
x = 28/14
x = 2
Plug in x = 2 in equation (I)
9*2 - 2y = 34
18 - 2y = 34
-2y = 34 - 18
-2y = 16
y = 16/-2
y = -8
Please give us more detail so I can further help you<span />
#1 divide by 6n to both sides to get n by itself
#2 multiply both sides by 6/5a to get a by itself
#3 multiply both sides by 2/5x to get x by itself
When you have whole numbers (no decimals) you can divide. When you have numbers with decimals, convert them to fractions and multiply by the reciprocal to get the variable by itself.
