Answer:

x =5

y = 35

Step-by-step explanation:

y = 7x

y = 3x+20

Since they both equal y, we can set them equal to each other

7x = 3x+20

Subtract 3x from each side

7x-3x = 3x+20-3x

4x= 20

Divide each side by 4

4x/4 =20/4

x = 5

Now find y

y = 7x

y = 7(5)

y = 35

Answer:

Store 1 Has a better deal as your paying 1.50 less which is 50 percent off

Step-by-step explanation:

Lets say a DVD costs 1.50

so if you bought 2 for the price of one it would be 1.50

3 for the price of 2 would be 3 dollars.

If you were to buy 2 CDS for the Price of 2 that would be 3 Dollars

3 CDS for the price of 3 would be 4.50

The Amount of money depends on the cost of 1 CD.

Store 1 has a 50 percent discount while Store 2 has roughly a 35 percent discount.

Answer:

1.) X/2= -25

Step-by-step explanation:

Answer:

Step-by-step explanation:

The diagram representing the trapezoid is shown in the attached photo. The median EF is a line segment that is half way between the 2 bases. The length of the median is the average of the two bases. Therefore,

EF = (12 + 18)/2 = 15

Two similar trapezoids are formed. They are ABFE and EFCD

By comparing both trapezoids, it means that

4/15 = FC/18

Cross multiplying, it becomes

4 × 18 = 15FC

72 = 15FC

FC = 72/15

FC = 4.8

Answer:

The area of trapezoid is 36 [tex]m^2[/tex].

Step-by-step explanation:

To find the area of a trapezoid, you need this formula:

[tex]A = \frac{(a+b)}{2} \times h[/tex]

[tex]a =[/tex] long base

[tex]b =[/tex]short base

[tex]h =[/tex] altitude (height)

-Use the following measures of trapezoid for the formula:

[tex]A = \frac{(8+4)}{2} \times 6[/tex]

-Then, you solve the formula:

[tex]A = \frac{(8+4)}{2} \times 6[/tex]

[tex]A = \frac{12}{2} \times 6[/tex]

[tex]A = 6 \times 6[/tex]

[tex]A = 36[/tex]

So, therefore, the area of a trapezoid is 36 [tex]m^2[/tex].

Answer:

first one right

Step-by-step explanation:

Answer:

Step-by-step explanation:

Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.

The SI unit of time is the second.

Now, suppose we need the velocity in feet per second. A simple calculation will help:

feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]

For a space capsule moving at 80 miles per hour, the velocity is given by

                          = 100 × 1.466667

                          = 146.67 ft/s [feet per second]

Answer:

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".

Step-by-step explanation:

In order to find the zeros of a function we need to find at which values for "x" make f(x) equal to zero. Therefore we have:

[tex]f(x) = x^3 - 2 \\0 = x^3 - 2\\x^3 - 2 = 0\\x^3 = 2\\x = \sqrt[3]{2} = 1.2599[/tex]

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".

Answer:

Step-by-step explanation:

The northbound car has traveled a distance of 6.2 miles.

Step-by-step explanation:

Step 1:

The eastbound car has traveled a distance of 5 miles and if a straight line is drawn between the two car's positions it would measure 8 miles.

This forms a triangle which has a hypotenuse measuring 8 miles while one of the other sides measures 5 miles.

Assume the distance traveled by the northbound car is x miles.

Step 2:

So the northbound car has traveled a distance of 6.244 miles. Rounding this off, we get 6.2 miles.

Answer:

Range = 16

Interquartile range 6

Step-by-step explanation:

Range: largest number minus smallest number

Range = 18 - 2 = 16

Interquartile range : right line on the box minus left line on the box

(75% point - 25% point) = 12 - 6 = 6

Answer:

Range = 16

Interquartile range 6

Step-by-step explanation:

Range: largest number minus smallest number

Range = 18 - 2 = 16

Interquartile range : right line on the box minus left line on the box

(75% point - 25% point) = 12 - 6 = 6!!!!!!!!!!!!!!!!!!!!!

Answer:

2 students are in both clubs

Step-by-step explanation:

x = 1 student (this number may be more than the total because one student can be in 2 clubs)

Club a = 13

Club b = 20

13 + 20 = 27x

Total members of clubs - total number of students = 27x - 25 = 2

2 students are in both clubs

Answer:

The relationship between the number of months after the first year and the amount remaining on the card is discrete.

The independent variable is the

number of months after the first year.

The dependent variable is the

amount remaining on the card.

The answers are; The relationship between the number of months after the first year and the amount remaining on the card is discrete.

The independent variable is the number of months after the first year.

The dependent variable is the amount remaining on the card.

The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Given that, A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.

The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse, which meant that, when the number of months after the first year increases, the amount on the remaining car decreases, linearly.

The Independent variable is the numbers of months after the first year.

The Dependent variable is the amount on the remaining card, because this amount depends on the time it has passed since the first year, which is our independent variable.

If we call "Y" our dependent variables and "X" our Independent variable, This relationship can be written as Y= 25 - 2.5x.

If no months had passed since the first year, then x= 0 and the amount in the card equals $25, while if one month has passed since the first year, x= 1 and y= 22.5 (The amount in the card in this case is $22.5.)

Hence, The answers are a) discrete b) numbers of months after the first year c) amount remaining on the card

g(x) = (x -39)^2 +74

Step-by-step explanation:

Given f(x)=x^2, after performing the following transformations: shift upward 74 units and shift 39 units to the right, the new function g(x) = (x -39)^2 +74

In mathematics, a transformation is a feature f, typically with a few geometrical underpinnings, that maps a fixed X to itself, i.e. f: X → X.

The Quantity of heat require is [tex]0.062kJ[/tex]

Step-by-step explanation:

This problem bothers on the topic of heat capacity.

Given data

mass of water m=  [tex]710 grams[/tex]

converting from grams to kg we have =[tex]\frac{710}{1000} = 0.71kg[/tex]

initial temperature T1= 4°C

final temperature T2= 25°C

heat capacity of water = [tex]4.184 J/g[/tex]

The expression for the quantity of heat required is given has

[tex]Q= mc(T2-T1)[/tex]

substituting our given data we have

[tex]Q= 0.71*4.184*(25-4)\\Q= 2.97*(21)\\Q= 62.38J\\[/tex]

In kilograms we have to divide by [tex]1000[/tex]

[tex]Q= \frac{62.38}{1000} = 0.062kJ[/tex]

Answer:

  (d)  528 ft³

Step-by-step explanation:

The shape is that of a trapezoidal prism. The front face is a trapezoid with bases 8 ft and 14 ft, and height 6 ft. Its area is ...

  A = (1/2)(b1 +b2)h = (1/2)(8 +14)(6) = 66 . . . . square feet

Then the volume is given by ...

  V = Bh

where B is the area of the (trapezoidal) base, and h is the height of the prism (8 ft). Filling in the values, we find ...

  V = (66 ft²)(8 ft) = 528 ft³

The pool can hold 528 ft³ of water.

Answer:

The price of one gallon of gasoline is $3.15

Step-by-step explanation:

If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":

2.4  p = 7.56

then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:

p = 7.56/2.4

p = $3.15

so this is the price per gallon of gasoline.

Answer:

The point M(Mx, My) is mid-point of AB with A(Ax, Ay) and B(Bx, By).

=> 2*Mx = Ax + Bx => 2*2 = 0 + Bx => Bx = 4

=> 2*My = Ay + By => 2*(5) = -1 + By => By = 11

=> B(4, 11)

=> Option A is correct
