Step-by-step explanation:
You are good eh I'm a newbie welp just gotta keep on answering
Eliinate y's
multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6
(x,y)
(4,6)
Answer:
b. 6¹⁰ / 7⁶
Step-by-step explanation:
(6⁵/7³)²
6 × 6 × 6 × 6 × 6 = 7776
7 × 7 × 7 = 343
(7776/343)²
7776²/343²
7776 × 7776 = <u>60.466.176</u>
343 × 343 = <u>117.649</u>
6¹⁰/7⁶
6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176
7 × 7 × 7 × 7 × 7 × 7 = 117.649
6¹⁰ = 7776²
7⁶ = 343²
= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>
