The property that justifies each step of 5(x-1) = 4x + 13 is 5x - 5 = 4x + 13.
What is distributive property ?Distributive property is when we distribute and multiply in between addition and subtraction
Given 5(x-1) = 4x + 3.
We know a(b+c) = ab + ac which is distributive property.
So, 5(x-1) = 4x + 3.
5x - 5 = 4x + 3.
Solving these problem and finding the value of x
5x - 5 = 4x + 13.
5x - 4x = 13 + 5.
x = 18.

given the weekly demand curve of a local wine producer is p= 50-0.1q, and that the total cost function is c= 1500+ 10q, where q bottles are produced each day and sold at a price of $p per unit. a)Express the weekly profit as a function of price.b) at what price must a bottle of wine be sold to realise maximum profit. c) what is the maximum profit that ca be made by the producer
Answer:
a)the weekly profit as a function of price is[tex]P=-10 p^2 + 600 p - 6500[/tex]
b) a bottle of wine be sold at $30 to realise maximum profit
c) the maximum profit that can be made by the producer is $2500
Step-by-step explanation:
The weekly demand curve of a local wine producer is p= 50-0.1q
p = price
q = quantity
Revenue function R =Price \times Quantity
R=(50-0.1q)q
[tex]R=50q-0.1q^2[/tex]
Cost function: c= 1500+ 10q
Profit function=R(x)-C(x)
Profit function= [tex]50q-0.1q^2-1500-10q[/tex]
Profit function= [tex]40q-0.1q^2-1500[/tex] ----1
We have q = 500 - 10 p using p = 50 − 0.1q
[tex]P=-0.1 (500 - 10 p)^2 + 40 (500 - 10 p)- 1500\\P= -10 p^2 + 600 p - 6500[/tex]
General quadratic equation:[tex]ax^2+bx+c=0[/tex]
On comparing
a = -0.1 , b = 40 , c = -1500
Maximum Profit is at q = [tex]\frac{-b}{2a}=\frac{-40}{2(-0.1)}=200[/tex]
To find price must a bottle of wine be sold to realise maximum profit
p= 50-0.1q
p= 50-0.1(200)=30
Substitute the value of q in profit function(1) get the maximum profit
So, Profit function= [tex]40\left(200\right)-0.1\left(200\right)^{2}-1500=2500[/tex]
Hence
a)the weekly profit as a function of price is[tex]P=-10 p^2 + 600 p - 6500[/tex]
b) a bottle of wine be sold at $30 to realise maximum profit
c) the maximum profit that can be made by the producer is $2500

Answer:
Slope-int form: y = 3x+5
Standard form: y - 3x = 5.
Step-by-step explanation:
(reminder: slope-intercept form is expressed as y=mx+b, and standard form is expressed as ax+bx=c.)
Since the slope is 3, the coefficient of x is also 3, which makes the equation y=3x.
But the y coordinate of the equation at x = -2 is -6, so we need to add 5 to the end of the equation, leaving you with:
y=3x+5.
To convert it to standard form, subtract 3x from both sides:
y - 3x = 5.

Answer:
x= 9/8 , -15/8
Step-by-step explanation:
Answer:
x = 1.125 , x = 9/8
Step-by-step explanation:
|8x+3| = 12
=> 8x + 3 = 12
=> 8x = 12-3 = 9
=> 8x = 9
=> x = 9/8
As 9/8 is a fraction let's make it a decimal.
9/8 * 125/125 (To make it into a power of ten so that we can convert)
=> 1125 / 1000
=> 1.125

An amusement park charges $20 to enter the
park and an additional fee for each time a guest
rides a roller coaster. Emily rode 5 times on a
roller coaster. Her total payment was $40.
Shaheem rode 7 times on a roller coaster. What
was his total payment?
Answer:
Shaheem paid $76 as his total.
Step-by-step explanation:
He paid $20 to get in, Emily paid $40 for 5 rides, and if you divide that to get the payment for one ride which is $8. So you multiply 8 by 7 because 7 is how many rides he rode which equals to 56, plus 20(his enter fee) would be $76.

the answer is -14 how about
study math next time
Answer:
Incorrect
Step-by-step explanation:
Use PEMDAS
Solve one side of the equation first
-21 × -4 + - 6
negative × negative = positive
84 + - 6
positive + negative = negative
84 - 6
78
Now solve the other side of the equation
-21 × -4 + (-21) × (-6)
negative × negative = positive
-21 × -4 + (126)
negative × negative = positive
84 + 126
210
Does 78 = 210?
No, so we can assume this equation is incorrect

Find the measure of the exterior angle.
64
76
Using the exterior angles theorem, the measure of the exterior angle(k) is 140 degrees.
How to find the exterior angles of a triangle?The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
The two remote interior angles are 76 degrees and 64 degrees.
Therefore,
76 + 64 = k
k = 140 degrees.

In the graph of an inequality, the area above a solid line through the points (−5, 2) and (3, 2) is shaded.
Which inequality does this graph represent?
A. y ≥ 2
B. y ≤ 2
C. y 2
Answer:
A. y ≥ 2
Step-by-step explanation:
First the line is solid, a complete line not dotted so the inequality sign to use is : ≥ or ≤
The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :
y ≥ 2
See attached graph below.
You are trying to find the distance AB between two points on either side of a river. You
measure the following distance:
Answer:32ft
Step-by-step explanation: I missed this as well, ED and AB are the same and if you don’t read you skip over the fact ED equals 32ft. Since ED and AB equal eachother it would be 32ft
The value of AB = 32 feet
What is congruency ?Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.
Given:
EC= 32 ft = BC
DC= 28 ft =AC
<ECD= <BCA
So, In ΔECD and ΔBCA
EC = BC
DC= AC
<ECD= <BCA
Thus, by SAS ΔECD ≅ ΔBCA
Hence, by CPCT : ED= BA = 32 ft.
