Let x be the number of red balloons and y the number of yellow balloons used, then
x + y ≥ 40
y ≥ 25
7x-3y=23
7x-3(-2)=23
7x+6 =23
-6. -6
7x=17
————
7. 7
x=2.42
So the first three are 6, 8, 10 and we can see that its going up by two so the next term would be 12.
Answer:
y = -3/2x + 11
Step-by-step explanation:
2x - 3y = 21 => 3y = 2x - 21 => y = 2/3x - 7
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of perpendicular line is -3/2
y = mx + b
y = -3/2x + b
Using (2,8)
8 = -3/2(2) + b
8 = -3 + b
b = 11
y = -3/2x + 11
Answer and Step-by-step explanation:
(1) Scale factor is a constant value that multiplies another value. For a puppy's weight, scale factor is 1.23.
The percentage growth is
1.23 = 1 + 0.23
Percentage is 0.23 or 23%.
(2) Equation for increase is

When w = 4000g:



Using the log law:


t.log(1.23) = log(10.96)
0.08990t = log(10.96)

t = 11.56
The puppy will weigh 4000 grams in 11 and half weeks or between 11 and 12 weeks.
