Answer:
x = 1.5 ; y = -0.5
Step-by-step explanation:
2x + 4y = 1 ---------------------(i)
3x - 5y =7 ----------------------(ii)
(i) * 5 10x + 20y = 5
(ii)*4 <u> 12x -20y = 28 </u>
add, 22x = 33 { here y will be eliminated}
x = 33/22 = 3/2
x = 1.5
Put the value of x in equation (i)
2*1.5 + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4 = -1/2
y = -0.5
Answer:
D
Step-by-step explanation:
(-1) + (-1) = -2... so 500 times... it would be -500.
Answer:
yep
Step-by-step explanation:
nice
Answer:
A) Function Rule: <u> y = x+3</u>
<u />
Substitution:
y = 2 + 3
y = 3 + 3
y = 4 + 3
y = 5 + 3
B) Function Rule: <u> y = 5x</u>
<u />
Substitution:
y = 5 * 2
y = 5 * 3
y = 5 * 5
y = 5 * 6
C) Function Rule: <u> y = x + (x - 1)</u>
<u />
Substitution:
y = 2 + (2 - 1)
y = 3 + (3 - 1)
y = 4 + (4 - 1)
y = 5 + (5-1)

Given expression: (A+b)^3.
We can expand it into three factors as (A+b)(A+b)(A+b).
First we would foil (A+b)(A+b) = 
Combining like terms, we get
= 
Now, we would multiply (A^2 +2Ab + b^2) and (A+b).
=
Combining like terms, we get
Therefore,
