Answer:
The answer is -1.255 for residual value.
Step-by-step explanation:
We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:
Residual value = Observed value - predicted value
Residual value = 26 - 27.255
Residual values = -1.255
the graph does not represent a function cause when you make a t chart and put all of the points on it some of the y's have the same x. to have a liniar function the x points and the y points have to be to one another accept the y points can have two of the different x points. you can also do the vertical line test to se if it is a function.
the answer is c.
Answer:
y = -2x - 2
Step-by-step explanation:
Given:
m = -2
Slope-intercept:
y - y1 = m(x - x1)
y + 8 = -2(x - 3)
y + 8 = -2x + 6
y = -2x - 2
Answer:
x = 17/2 = 8.500
Step-by-step explanation:
Equation at the end of step 1 :
2 • (x - 5) - 7 = 0
Step 2 :
Equation at the end of step 2 :
2x - 17 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 2x-17 = 0
Add 17 to both sides of the equation :
2x = 17
Divide both sides of the equation by 2:
x = 17/2 = 8.500
Answer:
Ground seats = 450 people
Balcony seats= 132 people
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
The money raised (6480) must be equal to the product of the charge per balcony seats (15) and the number of balcony seats sold (b) ;plus the product of the charge per ground seats (10) and the number of ground seats sold (g)
15 b +10 g =6480
The total number of people (582) must be equal to the sum of balcony seats sold (b) and ground seats sold (g).
b+g = 582
Multiplying the second equation by 10, and subtracting it to the first equation:
15 b +10 g =6480
-
10b+10g = 5820
__________
5b =660
Solving for b
b = 660/5 = 132
Substituting b=132 in the second equation:
132+g = 582
g= 582-132
g= 450
