Answer:
Graph ⇒ see the attached figure
Create a table ⇒ see the attached figure
Expression/Equation ⇒ y = 8x
What is the slope? ⇒ 8
What is the y-intercept? ⇒ zero
Step-by-step explanation:
Given: Meat costs $8.00 per pound at a store.
Let the number of pounds = x, and the total cost = y
So, the equation which represents the given situation is ⇒ y = mx
Where m is the slope.
If x = 1 pound , the meat costs = y = $8
So, y = 8x
The table can created by let values for x and find the values of y.
The attached table represents the table and the graph of y = 8x
The slope = 8
y-intercept is the value of y when x = 0
so, the y-intercept = 0
Answer:
the center: (-3; 2)
the radius: √65
the equation of the circle: (x + 3)² + (y - 2)² = 65
Start with the x intercepts.
You need to factor the original function.
y = x^2 - 4x - 21
y = (x - 7)*(x + 3) These are the correct factors.
The two roots are
x = 7
x = - 3
So the two points you want are (7,0) and (-3,0)
That makes the answer C <<<<========
The vertex is a little harder. You need to complete the square to get it. (I take it you don't know any calculus yet.
y = x^2 - 4x - 21
y = (x^2 - 4x + ... ) - 21
y = (x^2 - 4x + 4) - 21 - 4
y = (x - 2)^2 - 25
The vertex is (2,- 25)
The answer is B <<<<<<=======
