Are the expressions 8a2 - 4b + 7a2 and 5(3a2 - 2b) + 6b equivalent? Explain your reasoning.
Answer:
Yes, The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
Step-by-step explanation:
To answer the question you must simplify each expression, then compare them to find if they are equivalent or not
∵ The 1st expression = 8a² - 4b + 7a²
→ Add the like terms
∴ The 1st expression = (8a² + 7a²) - 4b
∴ The 1st expression = 15a² - 4b
∵ The 2nd expression = 5(3a² - 2b) + 6b
→ Multiply the bracket by 5
∴ The 2nd expression = 5(3a²) - 5(2b) + 6b
∴ The 2nd expression = 15a² - 10b + 6b
→ Add the like terms
∵ The 2nd expression = 15a² + (-10b + 6b)
∴ The 2nd expression = 15a² + -4b
→ Remember (+)(-) = (-)
∴ The 2nd expression = 15a² - 4b
∵ The 1st expression = The 2nd expression
∴ The two expressions are equivalent
∴ The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
Mackenzie works as a salesperson at an electronics store and sells phones and phone accessories. Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones. Write a system of equations that could be used to determine the number of phones sold and the number of accessories sold. Define the variables that you use to write the system.
Answer:
Let p= the number of phones sold
Let a= the number of accessories sold
Step-by-step explanation:
10p+4a=126
a=p+7
The system of equation should be 10p+4a=126 and a=p+7
Given that,
Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones.Based on the above information, the equation is as follows:
Here we assume p= the number of phones sold
And, a= the number of accessories sold
So, the equations are 10p+4a=126 and a=p+7

If 3x - 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y? Select all that apply.
Answer:
x = 4
y = -1
Step-by-step explanation:
3x-9y = 21
6x+3y =21
-2* (3x-9y) = -2*(21)
6x+3y = 21
-6x+18y = -42
6x+ 3y = 21
-6x+6x+18y+3y = -21
21y = -21
y --21/21
y = -1
3x-9y =21
3x - 9*(-1) = 21
3x + 9 =21
3x = 21-9
3x = 12
x = 12/3
x = 4

Leah is creating satin bows for a wedding. From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon. How much ribbon does Leah have left?
A.) -12 meters
B.) -5 meters
C.) 5 meters
D.) 12 meters
Answer:
C.) 5 meters
Step-by-step explanation:
From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon.
Step 1
3 4/9 meters + 6 5/9 meters
Least Common Denominator = 9
(3+ 6) + [ 4/9 + 5/9)
9 + [4 + 5/9]
9 + [9/9]
9 + 1
= 10 meters
This means, the total number of ribbons cut is 10 meters
The amount of ribbon Leah has left =
Initial length of ribbon - Amount of ribbon cut
= 15 meters - 10 meters
= 5 meters
Hence, Leah has 5 meters long of ribbon left
Answer:
the answer is 5 meters left

An SUV costs $26,425 and costs an average of $0.18 per mile to maintain. A hybrid model of the SUV costs $33,195 and costs an average of $0.13 per mile to maintain. After how many miles will the cost of the gas-only SUV exceed the cost of the hybrid?
Answer:
135,400 miles
Step-by-step explanation:
SUV cost = $26,425 + $0.18m
= 26,425 + 0.18m
Hybrid SUV cost = $33,195 + $0.13m
= 33,195 + 0.13m
Where,
m = number of miles
Equate the cost of the two SUVs
33,195 + 0.13m = 26,425 + 0.18m
33,195 - 26,425 = 0.18m - 0.13m
6,770 = 0.05m
divide both sides by 0.05
m = 6,770 / 0.05
= 135,400
m = 135,400 miles
The gas-only SUV exceed the cost of the hybrid after 135,400 miles

The constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4
For a graph with x and y-axis, we can say that y is directly proportional to "x" since it is a direct variation.
If y is directly proportional to x, this is expressed as:
y = kx
k is the required constant of variation.
Since the graph passes through the point (5,82), this shows that x = 5 and y = 82
Substituting into the formula:
82 = 5k
k = 82/5
k = 16.4
Hence the constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4

Answer:
Step-by-step explanation:
Given : For each sandwich:
Quantity of meat used = 4 ounces
Quantity of cheese used = 3 ounces
The combined ounces of meat and cheese are used on each sandwich =
Quantity of meat used + Quantity of cheese used
= 4 ounces + 3 ounces
= 7 ounces
Hence, The combined ounces of meat and cheese are used on each sandwich = 7 ounces

The domain of a function is given by {-4,2,8}. If the function is defined by y= x +1 /3 ,then which of the following values is a member of the range?
Answer:
{-1, 1, 3}
Step-by-step explanation:
Given the function
y = (x + 1)/3
The domain are the input value x while the range are the output values given the input value x;
Given the domain {-4, 2, 8}
when x = -4;
y = (-4+1)/3
y = -3/3
y = -1
when x = 2;
y = (2+1)/3
y = 3/3
y = 1
when x = 8;
y = (8+1)/3
y = 9/3
y = 3
Hence the member of the range are {-1, 1, 3}
