Because 3^2 = 9
When you do (⅓)^2 what you are really doing is
(1^2)/(3^2) = 1/9
If you have (⅔)^2 you do
(2^2)/(3^2) = 4/9
Fractions get smaller because the denominator is also being squared which makes the denominator get bigger and when the denominator is bigger, you are dividing by a larger number which gives you a smaller answer. Whereas when you raise a whole number to an exponent, only the numerator get bigger because the denominator is 1 and 1 raised to any exponent is still 1
3^2 = (3^2)/(1^2) = 9/1 = 9
Answer:
Q1. (a) (i) p = -9, q = 11
Q3. (a) Line 1: x = 0.5
Line 2: x = -2
Q3. (b) (i) (ii) For both lines, they will be perpendicular to the x-axis and they will pass their respective x-coordinates of 1 and -2 1/2.
Step-by-step explanation:
Q1. (a) (i) 5(-5) - 3p = 2
-25 - 3p = 2
3p = -25 - 2
p = -27/3
p = -9
5(7) - 3q = 2
35 - 3q = 2
3q = 35 - 2
3q = 33
q = 11
Q3. (a) Since all points on Line 1 have x-coordinates of 0.5, we can conclude that the equation is x = 0.5. Same goes for Line 2, of which all points have x-coordinates of -2 instead, making the equation x = -2.
Hope this helped!
-2x + 5 = -1
subtract 5 from both sides: -2x = -6
divide each side by -2: x = 3
plug in 3: 5(3)
multiply: 15
the value of 5x is 15.
In one day all the pets eat 9/4 cups of food. 9/4 ×8=72/4 72/4 simplified is 18. So in 8 days, all of the pets eat 18 cups of food!
Hope this helps
