In order to solve the equation shown we'll need either the numeric variable for Q or P
Answer:
6ab.
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)
Answer:
-114
Step-by-step explanation:
f(x) = -4x^2 +5x
Let x = 6
f(6) = -4(6)^2 +5(6)
= -4(36) +30
- 144+30
= -114
Answer:
12.8 years
Step-by-step explanation:
Put the given numbers into the model and solve for t.
It will take about 12.77 years for the population to triple at the current growth rate.
Answer:
y - 12 = (-4/5)(x + 1)
Step-by-step explanation:
Let's use the point-slope formula y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
1. Find the slope. As we go from (-1, 12) to (4, 8), x (the run) increases by 5 and y (the rise) decreases by 4. Thus, the slope is m = rise/run = -4/5.
2. Plug into the formula (given above) the following:
-4/5 for m, -1 for x and 12 for y:
y - 12 = (-4/5)(x + 1)
