Answer:
y=-2/5x+3
Step-by-step explanation:
y+7=-2/5(x-10)
step 1:
-2/5(x-10)= -2/5x-4
step 2:
y+7=-2/5x-4+7
step 3:
y=-2/5x+3
Answer:
d) -3
Step-by-step explanation:
The equation of a parabola in vertex form is given as:
y = a(x - h)² + k. Where (h, k) is the vertex of the parabola.
Given that the vertex of the parabola is at (4,-3) i.e h = 4 and k = -3.
The equation of the parabola is given as:
y = a(x - 4)² + (-3)
y = a(x² - 8x + 16) - 3
y = ax² - 8ax + 16a - 3
Given that when x = 5, y = -6. i.e:
-6 = a(5)² - 8a(5) + 16a - 3
- 6 = 25a - 40a + 16a - 3
-6 + 3 = a
a = -3

Answer:
A. -1 ≤ x ≤ 3
Step-by-step explanation:
The range is the horizontal extent of the graph--the set of x-values for which the function is defined. Here, the graph extends from x = -1 to x = 3, with both end points included. The range is ...
-1 ≤ x ≤ 3
Answer:
65 ounces
Step-by-step explanation:
Number of dogs = 4
Each day, they ate 13/4 pounds of food
1 pound = 16 ounces
If 4 dogs eat 13/4 pounds of food
1 dog will eat x pounds of food
1 dog will eat = (1 * 13/4) / 4 = 13 /16
1 dog will eat 13 / 16 pounds of food each day.
1 pound = 16 ounces
13 / 16 pounds = y ounces
y = (13/16 * 16) / 1
y = 13 ounces
Each dog eats 13 ounces of food daily.
In five days, each dog will eat 13 * 5 = 65 ounces of food.
