Who do you solve y= -5/2x-7
Answer:
To solve the equation y = -5/2x - 7, we can first multiply both sides of the equation by 2x + 7, which is the denominator of the fraction on the right-hand side. This gives us the equation 2xy + 7y = -5, which we can rearrange to isolate the variable y on one side of the equation. Dividing both sides of the equation by 2x + 7, we get y = -5 / (2x + 7). This is the solution to the original equation.
Step-by-step explanation:
Simplify each term.
y= −5 x2 −7
bolivian coffee sells for $4.59 per pound, and colombian coffee sells for $5.95 per pound. how many pounds of each coffee should be mixed to produce 4000 pounds of mixture that will sell for $5.10 per pound?: * a) bolivian: 2500 pounds; columbian: 1500 pounds b) bolivian: 2000 pounds; columbian: 2000 pounds c) bolivian: 2250 pounds; columbian: 1750 pounds d) bolivian: 1500 pounds; columbian: 2500 pounds e) bolivian: 1000 pounds; columbian: 3000 pounds
The required pounds of Bolivian coffee and Colombian coffee are 2500 and 1500 respectively.
How we use the linear equation of two variable to solve this problem?
A equation is supposed to be linear equation in two factors in the event that it is written as ax + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are direct conditions in two factors.
According to question:Let x be the pound of Bolivian coffee and y is that of Colombian coffee.
Bolivian coffee sells for $4.59 per pound, and Colombian coffee sells for $5.95 per pound and whole mixture sells for $5.10.
So, 4.59x + 5.95y = 5.10(4000)
4.59x + 5.95y = 20400--------------------(1)
and x + y = 4000-----------------------------(2)
On solving above two equation, we get
x = 2500 pounds and y = 1500 pounds
Thus, required pounds of two coffees are 2500 and 1500.

a rectangular poster is to contain square inches of print. the margins at the top and bottom of the poster are to be inches, and the margins on the left and right are to be inch. what should the dimensions of the poster be so that the least amount of poster is used?
The Poster Dimensions of rectangle will be:
W = 18 inches
Y = 36 inches
Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (square centimeters, square inches, square feet, etc.). The area of a rectangle is the number of unit squares that fit in the rectangle. Examples of rectangles are flat surfaces such as laptop monitors, chalkboards, and painting canvases. You can use the rectangle area formula to find the space occupied by these objects.
Now,
Let's say the printable area of a rectangular poster is 512 square inches
"x". " and "y" - the dimensions of the printed area of the poster
A(p) = printed area of the poster = x × y
512 = x × y ⇒ y = 512/x
Therefore, The total area of the poster is:
A( t) = ( y + 4 ) × ( x + 2 )
⇒ A(t) = yx +2y +4x + 8 and y = 512/x
Total Area of x or Total poster area as x function:
A(x) =( 512/x)*x + 2* (512/x) + 4*x + 8
A(x) = 512 + 1024/x + 4 *x + 8
⇒ A(x) = 520 + 1024/x + 4*x
Differentiating both sides of the equation gives:
A´(x) = - 1024/x² + 4
A´(x) = 0
⇒ - 1024 /x² = -4
⇒ 4*x² = 1024
⇒ x² = 1024/4
⇒ x² = 256
or, x = 16 inches
and y = 512/x
⇒ y = 512/16
⇒ y = 32 inches
So x is found, the y dimension of the print area, Than n is the dimension of the poster:
Therefore,
w = x + 2 ⇒ w = 16 + 2 w = 18 in
And,
Y = y + 4 ⇒ Y = 32 + 4 Y = 36 in

Work done by the person for the displacement of 100m along +x-axis with constant velocity and mass of 10kg is equal to 0Joule.
As given in the question,
Mass of a person 'm' = 10kg
Displacement of the person while walking along +x axis 'd'= 100m
Constant velocity = 2m/s
Let 'w' be the work done by the person
Work = Force × Displacement
Force = mass × acceleration
Acceleration = (final velocity - initial velocity)/ total time taken
Here, Constant velocity ⇒final velocity - initial velocity = 2- 2
= 0m/s
⇒Acceleration = 0m/s²
⇒Force = 10 × 0
= 0Kgm/s²

Which equation represents a line passing through the point (8,33) with a slope of 3?
The slope intercept form of equation of required line is y = 3x + 9
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Here,
Slope = 3
The line passes through (8, 33)
Equation of required line
y - 33 = 3(x - 8)

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Here, we have
There are 52 cards, of which 4 are kings.
There are 52 cards, of which 13 are diamonds.
But there are only 3 cards that are kings which are not diamonds, and only 12 cards that are diamonds but not kings, there’s one card that is both a king and a diamond.
So, there are 3/52+12/52=15/52 chances of drawing a card that is king or diamond but not both.
There are 3/52+12/52+1/52=16/52 chances of drawing a card that is king or diamond or both.
Hence, the probability that it will be a king or a diamond is 4/13.
