21.50 for 4 pounds of lunch meat or $15.10 for 3 pounds of lunch meat

Answer:

  both size boxes are $18 each

Step-by-step explanation:

Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...

  3x +14y = 306

  7x +7y = 252

Doubling the second equation and subtracting the first, we have ...

  2(7x +7y) -(3x +14y) = 2(252) -(306)

  11x = 198

  x = 18

  y = 252/7 -x = 36 -18 = 18

A small box costs $18, as does a large box.

The simplest form of the function is f(x) = x2. The graph is a parabola often called the basic parabola.

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

here, we have,

Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form.

Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve.

Solve f{x}=x-2?

f(x)=x-2    x∈R

Answer:

x = 6

Step-by-step explanation:

In order to find the value of x, first we need to prove the triangles PQS and RQS as congruent. Let us do it.

[tex] In\: \triangle PQS \:\& \:\triangle RQS\\\\

PS \cong SR.... (given) \\\\

\angle PSQ \cong\angle RQS... (\because QS\perp PR) \\\\

QS \cong QS... (Common \: side) \\\\

\therefore \triangle PQS \cong \triangle RQS.. (SAS \: Postulate) \\\\

\therefore PQ = QR... (BY\:CSCT) \\\\

\therefore 2x + 15 = 5x - 3\\\\

\therefore 2x - 5x = - 3 - 15\\\\

\therefore - 3x = - 18\\\\

\therefore x =\frac{-18}{-3}\\\\

Answer:

So, cost of 1 pair of shorts =$12

Step-by-step explanation:

Let cost of 1 pair of jeans =x

Cost 1pair of shorts =y

cost of 1 pair of shirts=z

We can set up equations as

x+4 y+2 z=84

2 x+1 y+3 z=76

x+2 y+z=52

Solve the equations for y.

Take first and second equations multiply first equation by -2 and add it with second equation.

-2 x-8 y-4 z=-168

2 x+1 y+3 z=76

Add them, it gives -7 y-z =-92

Now, take second and third equations, multiply the third equation by -2 then add them together.

2 x +1 y +3 z =76

-2 x-4 y-2 z=-104

Add them together,

-3 y +z =-28

Now, take the -7 y -z =-92 and -3 y +z =-28

Add the equations

-10 y = -120

Divide both sides by -10

y =12.

So, cost of 1 pair of shorts =$12

z=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−2−7x=10x+4

3x+−2+−7x=10x+4

(3x+−7x)+(−2)=10x+4(Combine Like Terms)

−4x+−2=10x+4

−4x−2=10x+4

Step 2: Subtract 10x from both sides.

−4x−2−10x=10x+4−10x

−14x−2=4

Step 3: Add 2 to both sides.

−14x−2+2=4+2

−14x=6

Step 4: Divide both sides by -14.

−14x−14=6−14

x=−3/7

Answer:

x=−3/7

The  value of x is -3/7.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x-2-7x = 10x + 4

Now, solving for x

3x-2-7x = 10x + 4

-4x - 2= 10x + 4

-4x - 10x = 4 + 2

-14x = 6

x= -6/14

c= -3/7

Hence, the value of x is -3/7.

Answer:

The coordinates of k are (-2,-1)

Step-by-step explanation:

Here, we are interested in calculating the coordinates of point k.

Mathematically, we will use the internal division formula for this;

This would be;

(x,y) =( nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)

where m = 1 , n = 4

x1 = -2 , x2 = 8

y1 = -4 , y2 = 11

we now make the substitutions into the formula;

(x,y) = 4(-2) + 1(-2)/(1+4) , 4(-4) + 1(11)/(4 + 1)

(x,y) = (-8-2)/5 , (-16 + 11)/5

(x,y) = -10/5 , -5/5

(x,y) = (-2, -1)

Answer:The answer is (x,y)->(+4,y-5)

Step-by-step explanation:

since -4 to 0 is + 4 and 2 to -3 is -5

The correct mapping is (x, y) ⇒ (x + 4, y - 5)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).

Since the vertex Y(-4, 2) was translated to Y'(0, -3), hence the triangle was translated 4 units to the right (-4 + 4 = 0) and 5 units down (2 - 5 = -3). This can be represented by the mapping:

(x, y) ⇒ (x + 4, y - 5)

Therefore to find x and z coordinates,  use the mapping:

(x, y) ⇒ (x + 4, y - 5)

Answer:

46 (23%)

Step-by-step explanation:

If 10% of x is 20, we can assume that 100% of x is 200. This is because since 10% is such a nice number to work with, we can simply add a zero to the end of it and the number. Now, we can see that 50% is 100 and 25% is 50. 20% is 40 and 10% is 20. 5% is 10 and 1% is 2. That being said, we need to do 50% + 3%. Which leaves us with 50 (25%) - 4 (2%). That being said, the answer is 46 (23%).

since f(a) = 6

6 = 12 - 5 a

6 - 12 = 12 - 5a - 12

= -6 = -5a

= -6/-5 = -5a/-5
