Answer:
55
Step-by-step explanation:
No matter what happens in between, the average rate of change between 2 points of any interval is the slope of the 2 points of the interval.
The 2 points are (-8, -50) and (-6, 60), and we need to find the slope (which, as a reminder, is change in x over change in y):
(60-(-50))/(-6-(-8)) = (110)/(2)=55
Therefore, the average rate of change between the interval -8≤x≤-6 is 55.

Answer:
R: (Y| E R {-4<=y<=-1})
Step-by-step explanation:
Just look at where the graph is limited to vertically, in this case -1 and -4.
The range of the given graph is [-4,-1] and this can be determined by observing the given graph.
The following steps can be used in order to determine the range of the given graph:
Step 1 - The range is the different values of 'y' at different values of 'x'.
Step 2 - According to the given graph, the maximum value of 'y' is -1.
Step 3 - According to the given graph, the minimum value of 'y' is -4.
Step 4 - So, the range of the given graph is given below:

Answer:
0.73
Step-by-step explanation:
3 2/5 = 17/5, 2 2/3 = 8/3
17/5 - 8/3
3/3 x 17/5 = 51/15
5/5 x 8/3 = 40/15

-2x - 3(6x - 11) = -7
Answer:
x=40/21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−3x−3(6x−11)=−7
−3x+(−3)(6x)+(−3)(−11)=−7(Distribute)
−3x+−18x+33=−7
(−3x+−18x)+(33)=−7(Combine Like Terms)
−21x+33=−7
−21x+33=−7
Step 2: Subtract 33 from both sides.
−21x+33−33=−7−33
−21x=−40
Step 3: Divide both sides by -21.
−21x

Let x be the number of invitations and y be the price of the printing job. The point-slope form of an equation that models the situation is
Answer:
p1: y-100=1.6(x-25)
p2 y=1.6x+60
p3 slope; 1.60
p4 y intercept, slope intercept form, easier to fine using slope intercept
Step-by-step explanation:
this was for savvas 2.2 practice
The required point slope of the equation is y-100=1.6(x-25) and the slope-intercept equation y = 1.6x + 60 and the slope represents the cost per invitation.
Given that,
The total price of a printing job at Incredible Invites includes the cost per invitation plus a one-time set-up fee. Write equations in point-slope and slope-intercept forms to model the situation. What part of the equations represents the cost per invitation is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Let the number of invitations be x, and the total cost be y.
Slope-point form of the equation is given by,
(y - y₁) = (y₂ - y₁)/ (x₂ - x₁ ) (x - x₁)
substitute value in the equation,
y - 100 = (140 - 100)/ (50 - 25)(x - 25)
y - 100 = 40 / 25 (x - 25)
y - 100 = 1.6 (x - 25) - - - - - - (point-slope form)
y = 1.6x - 25 * 1.6 + 100
y = 1.6x - 40 + 100
y = 1.6x + 60 - - - - - (slope-intercept form)
Slope = 1.6
Thus, the required point slope of the equation is y-100=1.6(x-25), and the slope-intercept equation y = 1.6x + 60, and the slope represents the cost per invitation.

Error Analysis: George was trying to rearrange the formula below to slope-intercept form, y = mx + b. by
solving for y. Identify her mistake and correct the error.
y + 20 = 2(x +20)
y + 20 = -x +20
PLEASE HELP!
Answer:
George's mistake would be:
Instead of 2x + 40, she has made - x + 20.
Step-by-step explanation:
Slope - Intercept Form = y = mx + b
y + 20 = 2(x +20)
y + 20 = 2x + 40
- 20 - 20
----------------------
y = 2x + 20
(Should have been the answer)
BUT,
George's Solving:
y + 20 = 2(x + 20)
y + 20 = -x + 20
George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.
Write a formula that will help Greg determine
how much money he will earn in one week.
Let's let
a = total amount earned
h = hours worked in one week
b = number of bushels picked
Use the curved parentheses 'O', if required.
Do not use other parentheses like '{ }' or '[ ]'.
Answer:
a = 3h + 2.50b
Step-by-step explanation:
Greg picks apples to make money over the summer. He earns $3 an hour plus $2.50 for each bushel he picks. Write a formula that will help Greg determine how much money he will earn in one week.
Let
a = Total amount earned
h = Hours worked in one week
b = Number of bushels picked
Solution:
Amount earned per hour = $3
Amount earned per bushel picked = $2.50
Total amount earned = (Amount earned per hour) ( Hours worked in one week) + (Amount earned per bushel picked) (Number of bushels picked)
a = 3*h + 2.50*b
= 3h + 2.50b
a = 3h + 2.50b
