Answer: ok, remember that when
x^a=x^b, when x=x, then a=b
also
x^-m=1/(x^m)
and
(x^m)^n=x^(mn)
so
we can rewrite 1/7 as 7^-1
so
and 343=7^3
7=7 so
-3a-3=3a-3
add 3a to both sides
-3=6a-3
add 3 to both sides
0=6a
0=a
a=0

Answer:
-2
Step-by-step explanation:
Equate the expressions for y. This gives ...
... x - 1 = 2x + 1
Add -1-x to get ...
... -2 = x . . . . your value of x
Answer:
(
5.5
,
4
)
Step-by-step explanation:
Use mid point formula shown in image
first x= (X+X)/2
x=(4+7)/2
x=11/2
x=5.5
y=(Y+Y)/2
y=(2+6)/2
y=8/2
y=4
(5.5,4)
Answer:
[A] 20%
[B] 400%
Step-by-step explanation:
Part A:
<u>To Find: Percentage</u>
= Price in 1985/price in 2003
Thus,
$62000×100%=6200000÷310000=20%
Part B:
<u>To FInd: Percentage increase</u>
= (Price in 2003-price in 1985)/price in 1985
Thus,
$248000×100=$24800000÷62000=400%
