Answer:
y = - 17
Step-by-step explanation:
6y + x = - 59 → (1)
x = - 2y + 9 → (2)
substitute x = - 2y + 9 into (1)
6y - 2y + 9 = - 59
4y + 9 = - 59 ( subtract 9 from both sides )
4y = - 68 ( divide both sides by 4 )
y = - 17
When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 3 kg, the acceleration of the object is 25 m/s^2. If the same force acts upon another object whose mass is 5 kg, what is this object's acceleration?
If the same force acts upon another object whose mass is 5 kg, the object's acceleration will be 1.667 m/s^2.
How can the acceleration be calculated?We were told that the constant force acts upon an object, and the acceleration of the object varies inversely with its mass, which can be interpreted as :
A = k/M
where M is the mass of the object.
A = acceleration
the k= proportionality constant
then we were told that mass is 3 kg, the acceleration of the object is 25 m/s^2
then substitute into the equation as:
25 =k*3
k= 25/3
then we were told that when mass is 5 kg, then acceleration will be ?
A= (25/3 )/5 = 1.667m/s^2.

how to find the area with a circumfernece of 18
The area of the circle with the circumference 18 units is 25.80 square units
How to calculate the area of the circle?The given parameters are
Circumference = 18 units
As a general rule, circumference are represented by the variable C
So, we have the following representation equation
C = 18
The circumference of the circle can be calculated as
C = 2πr
Next, we substitute the value of the variable C in the above equation
i.e. C = 18
So, we have the following equation
2π * r = 18
Divide both sides by 2π
r = 9/π
The area of the circle can then be calculated using the following area formula
A = πr²
Next, we substitute the value of the variable r in the above equation
i.e. r = 9/π
A = π * (9/π)²
Evaluate the exponents
This gives
A = π * 81/π²
Evaluate the products
So, we have
A = 81/π
As a general notation, π = 3.14
So, we have the following equation
A = 81/3.14
Evaluate the quotient
A = 25.80
Hence, the area is 25.80 square units

Consider the two points F(-9,0) and G(9,0) as the foci of an ellipse. The length of the major axis is 36. Give the equation of the ellipse.
well, one focus point at (9 , 0) and another at (-9 , 0) will mean the major axis runs over the x-axis, with a center at the origin, so the "c" distance will be 9 units, and since the major axis is 36 units, that means its "a" component or namely its half is half of 36 or 18 units, so

The cost to produce x units of wire is C= 45x + 450, while the revenue is R= 70x. Find the interval where the product will at least break even.
The interval where the product will be at least break even equals to 18 units.
What is a break even point?In accounting, the break-even point refers to the production level at which total revenues equal total expenses.
Given data
Cost is given as C = 45x + 450
Revenue is given as: R = 70x
In this case, the point of breakeven will be:
Cost = Revenue
45x + 450 = 70x
We will collect like terms:
70x - 45x = 450
25x = 450
We will divide both side by 25:
25x/25 = 450/25
x = 18
Therefore, the interval where the product will be at least break even equals to 18 units.

A trail mix is made by adding cashews that sell for $2.75 per pound to chocolate candies that sell for $1 per pound. How many of each should be used to get 50 pounds of trail mix that sells for $2 per pound?
Complete the statements.
The 50 pounds of trail mix includes [DROP DOWN 1] pounds of cashews and [DROP DOWN 2] pounds of chocolate candies.
The 50 pounds of trail mix includes 28.57 pounds of cashews and 21.43 pounds of chocolate candies.
What pounds of cashew and chocolate candies should be mixed to make the trail mix?let
x = pounds of cashewy = pounds of chocolate candiesx + y = 50
2.75x + y = 50 × 2
Solve the equation simultaneously
x + y = 50
2.75x + y = 100
Substract the equations2.75x - x = 100 - 50
1.75x = 50
x = 50/1.75
x = 28.57 pounds
Substitute into
x + y = 50
28.57 + y = 50
y = 50 + 28.57
y = 21.43 pounds
So therefore, the pounds of cashew and chocolate candies needed are 28.75 and 21.43 respectively.

The missing values for gallons of gasoline remaining is 11,6,1.
Given that equation shown below can be used to find the gallons of gasoline remaining (g) after distance driven (d).
We want to find the missing values for gallons of gasoline remaining.
The given equation is g=16-(1/20)d
When the distance is 100 then we will find the gallons of gasoline remaining by substituting d=100 in given equation, we get
g=16-(1/20)100
g=16-5
g=11
When the distance is 200 then we will find the gallons of gasoline remaining by substituting d=200 in given equation, we get
g=16-(1/20)200
g=16-10
g=6
When the distance is 300 then we will find the gallons of gasoline remaining by substituting d=300 in given equation, we get
g=16-(1/20)300
g=16-15

The linear function that is graphed on the grid is g(x) = (15/2)x + 45 , the correct option is (d) .
In the question ,
a linear function graph is shown ,
we have to find that linear function .
So , From the given graph we can see that
the graph passes from the points (2 , 60) and (6 , 90)
in order to find the equation , we first need to find the slope .
slope = (90 - 60)/(6 - 2)
= 30/4
= 15/2
So , the equation of the line passing through the points (2 , 60) and slope 15/2 is
(y - 60) = 15/2(x - 2)
y - 60 = (15/2)x - 15
Adding 60 to both the sides ,
we get
y - 60 + 60 = (15/2)x - 15 + 60
y = (15/2)x - 15 + 60
y = (15/2)x + 45
function is (15/2)x + 45
Therefore , The linear function that is graphed on the grid is g(x) = (15/2)x + 45 .

The lengths of the three sides of a triangle (in feet) are consecutive even integers. If the perimeter is 60 feet, find the value of the shortest of the three side lengths.
Step-by-step explanation:
3 consecutive even integer numbers :
x
x + 2
x + 4
their sum is the perimeter : 60 ft.
x + x + 2 + x + 4 = 60
3x + 6 = 60
3x = 54
x = 18
the shortest of the 3 sides is 18 ft.
and then we have the other 2 sides with 20 and 22 ft.

1. The cost of bell peppers varies directly with the weight of bell peppers, as shown in the table. Write a direct variation equation to represent this relationship. Then identify the constant of variation and interpret its meaning.
The constant of variation is 1.75 for every unit increase in x (weight), and the cost(y) value increases by $ 1.75.
What is the equation?
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The difference between two consecutive entries is constant, as we can see = 1.75
⇒ 7 - 5.25 = 1.75
⇒ 8.75-7 = 1.75
⇒ Slope(m) = 1.75
The slope represents the variable's rate of change.
y - 3 = m(x - 5.25)
y - 5.25 = 1.75(x-3)
y = 1.76x
Thus, the constant of variation is 1.75
This indicates that for every unit increase in x (weight), the cost(y) value increases by $ 1.75.
