Answer:
(0, -5), (4, -2), (-16, -17)
Step-by-step explanation:
I attach your full question in the image below
The equation is
3x-4y-8=12
Which can be rewritten as
3x-4y =12 +8
3x-20 = 4y
y = (3/4)*x - 5
We need to check each individual case
(0,-5)
y = (3/4)*(0) - 5
y = -5
True
(4,-2)
y = (3/4)*(4) - 5
y = -2
True
(8,2)
y = (3/4)*(8) - 5
y = 1
False
(-16,-17)
y = (3/4)*(-16) - 5
y = -17
True
(-1,-8)
y = (3/4)*(-1) - 5
y = -23/4
False
(-40,-34)
y = (3/4)*(-40) - 5
y = -35
False
(0,-5) (4,-2) and (-16,-17) are the solutions
11. 57% = 0.57
12. retail price = c + (0.57c)
13. retail price = 45 + (0.57 x 45)
retail price = 45 + 25.65
retail price = $70.65
14. 57% was added to the original price of the chain which is $25.65
A and c
step-by-step explanation
The expression would me m / 7 or m and 7 as a fraction. M is on the top
Answer:
1. Because it is an integer.
2. Because it is a terminating decimals.
3. Because it is a terminating decimal as well as an integer.
4.Because it is a natural number.
5.Because it is a terminating decimal when divided.
6. Because it is a whole number.
7. Because it is a natural number.
8. Because it is a terminating negative decimal when divided(simplified basically).
Step-by-step explanation:
Irrational numbers include:
Non terminating,and non recurring decimals.
Example: 1.2345677854903421......so on.
Hope this helps... :-)
