Answer:
Step-by-step explanation:
<u>Solving by completing square</u>
- -14 + x^2 = 5x
- x^2 - 5x - 14 = 0
- x^2 -2*2.5x + 6.25 - 20.25 = 0
- (x -2.5)^2 = 20.25
- (x - 2.5)^2 = 4.5^2
- x - 2.5 = 4.5 ⇒ x = 7
- x - 2.5 = -4.5 ⇒ x = -2
Answer:
76 ice cream cones
Step-by-step explanation:
Given the model : y=1.8x−76.9 ;
Which shows the relationship between temperature and number of ice cream cones sold ;
Using the model, the predicted number of ice cream cones sold when temperature is 85°F
Hence, x = 85
Putting x = 85 in the model and solve for y
y = 1.8(85) −76.9
y = 153 - 76.9
y = 76.1
Hence, the number of ice cream cones sold is 76
Answer:
Option: D is the correct answer.
The equation of line in point-slope form is given by:
y-9=2(x-1)
Step-by-step explanation:
We know that the point-slope equation of a line is given by:
y-b=m(x-a)
where (a,b) is the point from which the line passes and m is the slope of the line.
Here we are given that:
The line passes through (1,9) and slope of the line is given to be 2.
Hence,
(a,b)=(1,9) and m=2
Hence, the equation of line is given by:
y-9=2(x-1)
Therefore, the point slope intercept equation of the line is: D
