Answer:
The initial value of the function is 5
Step-by-step explanation:
we know that
The initial value of the function, is the value of the function when the value of x is equal to zero (the y-intercept)
In this problem
Observing the graph
The y-intercept is the point (05)
therefore
The value of the function for x equal to zero is 5
Answer:
∠ B = 60°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(10x - 45)° is an exterior angle of the triangle , then
10x - 45 = 3x + 4x = 7x ( subtract 7x from both sides )
3x - 45 = 0 ( add 45 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Then
∠ B = 4x = 4 × 15 = 60°
To complete the square, you can add (and subtract) the square of half the x coefficient.
... y = x² -10x + 30
... y = (x² -10x +25) + (30 -25)
... y = (x -5)² +5
Answer:
its SAS
Step-by-step explanation:
We need to write a proportion to solve this
7/3=35/x
105=7x
divide each side by 7
15=x so, there were 15 burgers without cheese.
We could add the cheese burgers 35 to burgers without cheese 15
35+15=50 burgers were sold.
