Answer:
y = 6.5
Step-by-step explanation:
Answer:
Domain = [1.5, 4.5]
Range = [4, ∞)
Step-by-step explanation:
The domain of the graph are the values along the input variable x while the range are the values of the output variable y;
From the figure the domain values falls with the range [-1.5, -4.5] while the range are with thin the values [4, ∞)
Answer:
Below.
Step-by-step explanation:
The area = the height (h) times the base.
So Q2:
21 = h * 7
h = 21/7 = 3
55 = b * 5
b = 11.
18.75 = h * 7.5
h = 18.75 / 7.5
= 2.5.
Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
(-5, 0) and (-1, 0) are the solutions of -2(-x - 3)² + 8 = 0
Step-by-step explanation:
- Step 1: Find the solutions of -2(-x - 3)² + 8 = 0.
Solutions are the intersecting points of y = -2(-x - 3)² + 8 and y = 0.
⇒ Solutions are (-5, 0) and (-1, 0)
- Step 2: (-5, 0) and (-1, 0) are solutions of -2(-x - 3)² + 8 = 0
