3x+3=3y ⇒ 3y-3x=3 ⇒3(y-x)=3 ⇒ y-x=1
2x-6y=2 ⇒ 2(x-3y)=2 ⇒ x-3y=1
We must to collect two equations.
x's is lost;
y-3y=2
-2y=2
y=-1 ; x-3.(-1)=1 ⇒ x=-2
Answer is (-2,-1)
If the decimal is in the tenths then the denominator would be like 10. Ex: Decimal: 0.2 Fraction- 2/10. and the same with hundredths, thousandths, etc.
Hello :
if : a <span>≡ 5 ( mod 7) ....(1)
b </span><span>≡ 6 ( mod 7) ...(2)
(1)×(2) : ab </span><span>≡ 30 ( mod 7)
</span>but : 30 = 7×4 + 2 ..... so : 30 ≡ 2 ( mod 7)
then : ab ≡ 2 ( mod 7)
Answer:
See below ~
Step-by-step explanation:
<u>Question 3 : (x, y - 5)</u>
- K' = (-3, 2 - 5) = <u>(-3, -3)</u>
- L' = (1, 4 - 5) = <u>(1, -1)</u>
- M' = (-1, 0 - 5) = <u>(-1, -5)</u>
- N' = (-5, -2 - 5) = <u>(-5, -7)</u>
<u></u>
<u>Question 4 : (x + 4, y + 1)</u>
- D' = (-4 + 4, 3 + 1) = <u>(0, 4)</u>
- E' = (0 + 4, 2 + 1) = <u>(4, 3)</u>
- F' = (-2 + 4, -6 + 1) = <u>(2, -5)</u>
- G' = (-6 + 4, -5 + 1) = <u>(-2, -4)</u>
