Answer:
x = -4/5 or x = 71/8
Step-by-step explanation:
Solve for x:
(5 x + 4) (8 x - 71) = 0
Split into two equations:
5 x + 4 = 0 or 8 x - 71 = 0
Subtract 4 from both sides:
5 x = -4 or 8 x - 71 = 0
Divide both sides by 5:
x = -4/5 or 8 x - 71 = 0
Add 71 to both sides:
x = -4/5 or 8 x = 71
Divide both sides by 8:
Answer: x = -4/5 or x = 71/8
Recall that the equation of a line passing through two points (x1, y1 and (x2, y2) is given by the formula (y - y1) / (x - x1) = (y2 - y1) / (x2 - x1).
Given that the line passes through the points (-4, 10) and (-1, 5), the equation of the line is given by (y - 10) / (x - (-4)) = (5 - 10) / (-1 - (-4)) = -5 / 3
3(y - 10) = -5(x + 4)
3y - 30 = -5x - 20
<span>3y = -5x + 10
5x + 3y = 10
y = -5/3 x + 10/3</span>
Answer: 4 and 1 over 2 ÷ 1 over 8
Step-by-step explanation:
Given that : Total distance drove by Parker =4 and 1 over 2 miles= miles
Distance drove by Parker each day = 1 over 8 mile= mile
To find the total number of days , we need to divide the total distance by the distance drove by him in each day.
Thus, the number of days he went driving=4 and 1 over 2 ÷ 1 over 8
Answer:
7946
Step-by-step explanation:
Answer:
Calories are transferred to flea beetle = 150 Calories
Calories are transferred to the sparrow = 15 Calories
Step-by-step explanation:
Given:
Calories in grass = 1,500 Calories
Find:
Calories are transferred to flea beetle
Calories are transferred to the sparrow
Computation:
According to food chain level only 10 % of Calorie transferred to the next level.
So,
Calories are transferred to flea beetle = 10% (Calories in grass)
Calories are transferred to flea beetle = 10% (1,500)
Calories are transferred to flea beetle = 150 Calories
Calories are transferred to the sparrow = 10% (Calories are transferred to flea beetle)
Calories are transferred to the sparrow = 10% (150)
Calories are transferred to the sparrow = 15 Calories
