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

−21

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:

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

Answer:

80

Step-by-step explanation:

Let h = number of rooms in the hotel

45% * h = 36

.45 h = 36

Divide by .45

.45h/.45 = 36/.45

h =80

There are 80 rooms in the hotel

Answer:

80 rooms

Step-by-step explanation:

Step 1:

45/100 = 36/x       Equation

Step 2:

45x = 3600      Multiply

Step 3:

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:

[tex]-4\leq y\leq -1[/tex]

The range of the given graph is [-4,-1].

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

51/15 - 40/15 = 11/15

11/15= 0.73

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.

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.
