Answer:
26 * 26^8 = 26^9
Step-by-step explanation:
Here, we want to write 26 * 26^8 in exponential form.
26* 26^8 is same as 26^1 * 26^8
According to the first law of indices, we are going to add the powers together;
Thus, this gives ; 26^(1 + 8) = 26^9
Answer:
set y=0 in one of the equations and then in the other one set x=0
Step-by-step explanation:
below is how you do it
y=5x-5 y=3x+3
0=5x-5 y=3(0) +3
5=5x y=3
1=x
10 800 0 to the first problem
Answer:x = 1
Step-by-step explanation:
3x + x/4 = x + 3/4
Subtract x from each side
2x + x/4 = 3/4
Times each side by 4
The 4 beneath the x cancels out
3/4 x 4 = 3
2x + x = 3
3x = 3
Divide each side by 3
x = 1
Y= 3(3)–2(3)2+5(3)3
y= 9–2*3*2+5*9
y=9–12+5*9
y=9–12+45
y=42
