L x w = 150+175t
=> l = (150+175t)/25
l = [25(6+7t)/25]
l = 6+7t
The expression of the length is l=6+7t
Answer:
Step-by-step explanation:
To find the midpoint, you use the formula .
The points are (-2,-1) and (4,-2).
[add]
[divide]
Now, we know the midpoint is .
This is a question of direct proportionality. The mass of hemoglobin is expected to increase with increase in volume of the blood.
Therefore;
10 cm^3 of blood ---------- 1.2 g of hemoglobin
39 cm^3 of blood ---------- x g of hemoglobin
The,
x = (39*1.2)/10 = 4.68 g of hemoglobin.
That is, 39 cm^3 of blood contains 4.68 grams of hemoglobin.
The answer is the average shoe size is 10 because mean is average.
Answer
Sarah’s graph is a vertical translation of f(x) = x².
Tammy's graph moved 9 units from f(x) = x² in a positive direction.
Sarah's graph has a y-intercept of 9.
