The equation for the number of 30 days periods until the value of both cards will be equal is 130 - 3x = 110 - 2.5x

let

Number of 30 days period = x

Gift card 1:

130 - 3x

Gift card 2:

110 - 2.5x

130 - 3x = 110 - 2.5x

130 - 110 = -2.5x + 3x

20 = 0.5x

x = 20/0.5

x = 40

So,

Gift card 1:

130 - 3x

= 130 - 3(40)

= 130 - 120

= $10

Gift card 2:

110 - 2.5x

= 110 - 2.5(40)

= 110 - 100

= $10

Therefore, the value of each card when they have equal value is $10

x and y graph also known as the x and y-axis are two important lines that make a graph. A graph consists of a horizontal axis and a vertical axis where data can be represented. A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph. These horizontal and vertical lines or axis in a graph are the x-axis and y-axis respectively.

A x and y graph can be defined by the two axes i.e. x-axis and the y-axis that form a coordinate plane for a graph. The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis. The point where the x and y-axis intersect is known as the origin and is used as the reference point for the plane.

y = 1/3x

when x =0

y = 0

Answer:

133

Step-by-step explanation:

for that we need to sort the numbers :

124,126,128,132,132,134,134,134,142,146

the median is the number, for which half of the other numbers are smaller, and the other half of the other numbers is larger.

as we have 10 numbers, there is no such single middle number.

instead, we take the 2 middle numbers and calculate their mean value. that is then the median.

the 2 middle numbers are based on our sorted list above

132, 134

the mean value is

(132 + 134)/2 = 133

and that is then the median.

Answer:

  4, 0, 3

Step-by-step explanation:

You want to know which numbers are possible values of m, given a graph of the values of m.

The graph shows an empty circle at m=6, and an arrow extending to the left from that point. The empty circle means that m=6 is not a possible value of m.

The arrow extends through possible values of m, and extends to negative infinity. That means m may have any value less than 6. Such values on the offered list are ...

  4, 0, 3

__

Additional comment

The values 6, 7, 9 are not covered by the dot or the arrow, so are not possible values of m.

Answer:

0, 3, 4

Step-by-step explanation:

When the circle is open and pointing to the left, it means that the variable is less than the number the circle is at. In this case, it means that the variable is less than 6, so you would select all values that are less than 6!

The y - intercept represents a cereal with zero grams of sugar that has a rating of about 57.

The general equation of a straight line is -

y = mx + c

where -

m → slope of line

c → y-intercept of line

Given a equation → y = 2.391x + 57.420 that models the taste rating of a cereal 'y' and 'x' represents the number of grams of sugar per serving.

The y-intercept of the equation represents the point at which the graph of the equation cuts the y - axis. Now, the coordinates of the y-intercept is of the form (0, y). Therefore, the x-coordinate will be 0. Now, the equation given is -

y = 2.391x + 57.420

Comparing it with the general equation of line -

y = 2.391x + 57.420

y =   mx     +    c

The y - intercept is c = 57.420

At x = 0, the equation becomes -

y = 2.391 x 0 + 57.420

y = 57.420

Now -

Number of grams of sugar per serving = 0

Taste rating of a cereal = y = 57.420

Therefore, the y - intercept represents a cereal with zero grams of sugar that has a rating of about 57.

x= 1

Cross multiply both sides

2.5x= 401/8

x= 401/8 ÷ 2.5

An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:

f(x) = eˣ

Generally speaking, a mathematical model for any quantity (water) that decreases by r percent per unit of time is an exponential function of this form:

P(t) = I(1 - r)^t

Where:

Substituting the given parameters into the formula, we have;

P(t) = I(1 - r)^t

P(50) = 1500 × (1 - 0.3)^0.2{50}

P(50) = 1500 × (0.97)^10

P(50) = 1,106 gallons.

Therefore, there would be 1,106 gallons of water left in the pool after 50 minutes.

Next, we would determine the amount of time it would take to have less than 1000 gallons in the pool:

P(t) = I(1 - r)^t

1000 = 1500 × (1 - 0.3)^0.2t

1000 = 1500 × (0.97)^0.2t

1000/1500 = (0.97)^0.2t

2/3 = (0.97)^0.2t

Taking the log of both sides, we have:

log0.97(0.2t) = log(2/3)

t = log(2/3)/(0.27log0.97)

Time, t = 66.6 minutes.

Also, it should be noted that 623 to 1 significant figure will be 600.

14 to 1 significant figure will be 10.

Therefore, the multiplication will be:

The length of the rectangle is 9 feet and the width of the rectangle is 10 feet.

The sum of a rectangle's boundary lengths on all sides is known as its perimeter. A rectangle's perimeter is a linear measurement that can be expressed in meters, feet, inches, or yards. Let's first comprehend the two fundamental characteristics of a rectangle.

Let the length of the rectangle be x feet

Then, the width of the rectangle will be x+1feet

We know that the perimeter of a rectangle is given by

P= 2(l+w)

Here

P= perimeter of a rectangle

l=length of the rectangle

w= width of the rectangle

Put l=x, w= x+1 and P= 38 in the perimeter formula

38 = 2(x+x+1)

Divide both sides by 2

19= x+x+1

19= 2x+1

Subtract 1 from both sides

18=2x

Divide both sides by 2

x=9 feet

This is the length of the rectangle.

Now, the width x+1 of the rectangle will be

The value of function f(x) at x = - 1 and x = 3, will be -

f(-1) = 3

f(3) = 3

We have a function f(x).

We have to evaluate it at x = -1 and x = 3.

A function in mathematics is a relation between a dependent and independent variables [y and x respectively]. In a function, the dependent variable (y) always depends on independent variable (x) for its value. It is denoted by - y = f(x).

According to the question, we have -

f(x) = [- x + 2  , x ≤ 1] and f(x) = [x² - 4x + 6,  x > 1]

Now, for x = -1, f(x) will be -

f(- 1) = - (-1) + 2 = 3

and

for x = 3, f(x) will be -

f(3) = 3² - 4 x 3 + 6 = 3

Hence, the value of function f(x) at x = - 1 and x = 3, will be -

f(-1) = 3

f(3) = 3

Herein we find a linear equation in a non-canonical form and to which we are asked to graph. According to geometry, lines can be created by knowing the location of two distinct points on Cartesian plane. The detailed procedure is now shown.

First, clear the variable y to obtain the explicit form of the linear equation:

y = 5 · x + 4

Second, look up for two distinct points on Cartesian plane by evaluating the expression at distinct values of x:

x = 0

y = 5 · 0 + 4

y = 4

x = 1

y = 5 · 1 + 4
