Answer:
Sum of the two separate equations.
The values satisfies the equation
Step-by-step explanation:
Given the equations for the two separate days :
125a +65 s = 1,200 - - - Friday
140a +50s = 1,230 - - - Saturday
265a+115s=2430 means the addition of the two separate equations which means the overall sales for the two days in one single equation.
B)
Because, Inputting the solution, satisfied the equation:
a = 7 ; s = 5
265a+115s=2430
265(7) + 115(5) = 2430
1855 + 575 = 2430

What is the value of x in the equation 3 - 2x= -1 5x?
Answer:
x = -2
Step-by-step explanation:
Simplifying
2x + -5x = 3x + 12
Combine like terms: 2x + -5x = -3x
-3x = 3x + 12
Reorder the terms:
-3x = 12 + 3x
Solving
-3x = 12 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3x + -3x = 12 + 3x + -3x
Combine like terms: -3x + -3x = -6x
-6x = 12 + 3x + -3x
Combine like terms: 3x + -3x = 0
-6x = 12 + 0
-6x = 12
Divide each side by '-6'.
x = -2
Simplifying
x = -2

What is the most reasonable domain for this situation? Explain your answer.
Answer:
34
Step-by-step explanation:
3esw
Answer:
The domain is 0≤t≤4
Step-by-step explanation:
The domain for this function should not include any negative t values (since that would mean the time is negative) and it should not include any t values where the height is negative (since a negative heigh doesn't make sense in the context of this problem). The t values between 0 and 4 are the only t values where both of these conditions are met.

Identify the x-intercept and y-intercept
Answer:
x: -6, y: -2
Step-by-step explanation:
look at the graph, I hope this is the x and y of the lines. It says the answers, but just identify it.
Answer:
(- 6, 0 ) and (0, - 2 )
Step-by-step explanation:
The x- intercept is the value of x on the x- axis where the line crosses.
Here x = - 6 ← x- intercept or (- 6, 0) in coordinate form
The y- intercept is the value of y on the y- axis where the line crosses.
Here y = - 2 ← y- intercept or (0, - 2 ) in coordinate form
ginger and matt have a total of $124.00 dollars. ginger has 1$2.00 more than 3/4 of the amount matt has. how much money does ginger have? How much does matt have?
The amount of money that Matt has will be $64.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Ginger and matt have a total of $124.00 dollars. Ginger has $12.00 more than 3/4 of the amount Matt has.
Let x be the amount that Ginger has and y be the amount that Matt has. Then the equations will be
x + y = 124 ...1
x = (3/4)y + 12 ...2
From equations 1 and 2, then we have
(3/4)y + 12 + y = 124
(7/4)y = 112
y = $64
Then the amount that Ginger has will be
x = (3/4)64 + 12
x = 48 + 12
x = $60
The amount of money that Matt has will be $64.

What’s the answer thank you
Answer:
C
Step-by-step explanation:
Division can be done by "cross multiplying", or multiplying the first equation by the reciprocal of the second equation.
In answer c, the first term remains the same, but the second is the reciprocal of the original. Also, the operator has changed from division to multiplication, so C is the correct answer.

Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers. ... Conversely, irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern.
Answer:
The rational number includes only those decimals, which are finite and repeating.
Step-by-step explanation:
Rational Number is defined as the number which can be written in a ratio of two integers in the form a/b where a,b are integers and b≠ 0, while an irrational number is a number which cannot be expressed in a ratio of two integers (that is it cannot be expressed as fraction in the form a/b).
The rational numbers are numbers whose decimal expansion are finite and repeating, while irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern e.g. π.
The graph of the cube root parent function y = RootIndex 3 StartRoot x EndRoot is translated to form f(x) shown on the graph.
On a coordinate plane, a cube root function goes through (negative 7, 0), has an inflection point at (negative 6, 1), and goes through (2, 3).
The graph of the cube root parent function y = RootIndex 3 StartRoot x EndRoot is translated to form f(x) shown on the graph.
On a coordinate plane, a cube root function goes through (negative 7, 0), has an inflection point at (negative 6, 1), and goes through (2, 3).
Which equation represents f(x)?
f(x) = RootIndex 3 StartRoot x + 6 EndRoot + 1
f(x) = RootIndex 3 StartRoot x minus 6 EndRoot + 1
f(x) = RootIndex 3 StartRoot x + 6 EndRoot minus 1
f(x) = RootIndex 3 StartRoot x minus 6 EndRoot minus 1
The translation of the parent function is:
g(x) = ∛(x + 6) + 1
How do translations work?There are two types of translations, these are:
Horizontal translation:
For a function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left.If N is negative, the translation is to the right.Vertical translation:
For a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
If N is positive the translation is upwards.If N is negative the translation is downwards.Here we start with the parent function:
f(x) = ∛x
And we apply two translations such that:
g(x) = ∛(x + a) + b
Such that:
g(-7) = 0
g(2) = 3
Then we have the system of equations:
∛(-7 + a) + b = 0
∛(2 + a) + b = 3
From the options, the only ones that make the first option true are:
g(x) = ∛(x + 6) + 1
Such that when evaluated in x = -7 we get:
g(-7) = ∛(-7 + 6) + 1 = ∛(-1) + 1 = 0
When evaluated in x = 2 it gives:
∛(2 + 6) + 1 = ∛(8) + 1 = 2+ 1 = 3
So the only option that meets these conditions is:
g(x) = ∛(x + 6) + 1
Which is a translation to the left of 6 units and up 1 unit.

How does the number line below represent the product of a positive number and a negative number? Drag words and numbers to explain. Each tile may be used once, more than once, or not at all. A number line from negative 5 to 0. Start at 0. Count back three times, each time by negative 1 point 5. End at negative 4 point 5. – 1.5– 3– 4.5positivenegative The number line shows 3 • = – 4.5. The number line shows three groups of a number, which results in a product.
Answer:
I cannot see the number line mentioned here, but I'll explain how you multiply negative and positive using tiles and number line.
To multiply positive and a negative nunber, for instance, 2(–3), you'll think of it as 2 groups of negative one in three's. Using tiles you have
–1 –1
–1 –1
–1 –1
Two groups of negative one in three's, adding that up we have 6.
Using number line. See 2(–3), for instance, as moving twice in intervals of –3. If I am to multiply that, starting from 0, if I move once, I'll land at –3, if I move one more time, I'll land at –6. Since I am to move twice, that's the required answer.

The profits of Mr. Unlucky's company can be represented by the equation f(x)=−3x^2+18x−4, where y is the amount of profit in hundreds of thousands of dollars and x is the number of years of operation. He realizes his company is on the downturn and wishes to sell before he ends up in debt.What is the maximum profit?
Answer:
Step-by-step explanation:
maximum years would be where x=-b/2a or -18/-6 or x=3
put that into the equation to get y=-27+54-4=23 hundreds of thousands.
from year 3 on, the profit decreases
the zero point is where y=0 this is -3x^2+18x-4=0
or 3x^2-18x+4=0
quadratic formula
x=(1/6)(18+/-sqrt(324-48)); sqrt 276=16.61
x=(34.61/6)=5.77 years, so 2.77 years of decreasing profits.

Elsa and two of her closest friends went out to dinner to celebrate Elsaś birthday. The bill for dinner totaled $74.80. If they decided to leave a 20% tip, what was the amount paid by each person in Elsaś party before taxes?
Answer:
$29.92
Step-by-step explanation:
Step one:
given data
The bill for dinner totaled $74.80
Then the tip is 20%
Required
The amount paid by each person after the tip was added to the cost of the dinner
Step two:'
the amount of the tip is
=20/100*74.80
= 0.2*74.80
=$14.96
The total is 14.96+74.80
=$89.76
The number of persons including the celebrant is = 3
so each person will pay
=89.76/3
=$29.92
