Answer:
(4.5,-6)
Step-by-step explanation:
6x = 27
x = 27/6=4.5
9-3y = 27
-3y = 18
y = -6
on the y axis put a dot and then go up 2 then right 1 and keep on doing that until u get a line then down to left 1
Answer:
Step-by-step explanation:
1) 2x+ 4 = 10
2x = 6
x = 3 (3 is the answer)
2) we have to substitute y with 3 and z with 4
3.75*3 + 6.50*4 ≥ 50
11,25 + 26 ≥ 50
37.25 ≥ 50
so the answer is no, because the total will be $37.25
3) 12k + 2 < 12
12k < 10
k < 5/6
3/4 < 5/6 so the answer is true
4) we have to try the options
a) 3*4 + 4*2 + 6 = 26
12 + 8 + 6 = 26
26 = 26 (true)
b) 3*5 + 4*6 + 6 = 26
15 + 24 + 6 = 26
45 = 26 (false)
c) 3*4 + 4*3 + 6 = 26
12 + 12 + 6 = 26
30 = 26 (false)
d) 3*3 +4*5 + 6 = 26
9 + 20 + 6 = 26
35 = 26 (false)
so the answer is x=4 , y=2
5) 3a + 4 ≥ 13
3a ≥ 9
a ≥ 3
so the answer is {3,4.5,5}
Tom would get £28.80
Sally would get £31.40
The difference is £2.60
Hey there!
36(2) * 30
36(2) = 72
72 * 30 = 2,160
3^3 = 3 * 3 * 3 = 9 * 3 ➡️ 27 ❌
3^4 = 3 * 3 * 3 * 3 = 9 * 9 ➡️ 81 ❌
3^8 = 6,561 ❌
3^12 = 531,441 (maybe)
Answer: Option D. 3^12 ☑️
Good luck on your assignment and enjoy your day!
