girls.

Answer:

3,231 feet

Step-by-step explanation:

Find the difference between the two heights by subtracting them:

2933 - (-298)

2933 + 298

= 3231

So, the difference in altitude is 3,231 feet

Answer:

3,231

Step-by-step explanation:

To get the answer, you should:

2,933 + 298 = 3,231

Answer:

[tex]\boxed {x = 0}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x - 10 = 5x - 10[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]x[/tex]:

[tex]x - 10 - 5x = 5x - 5x - 10[/tex]

[tex]-4x - 10 = -10[/tex]

-Add [tex]10[/tex] to both sides:

[tex]-4x - 10 + 10 = -10 + 10[/tex]

[tex]4x = 0[/tex]

-Since [tex]4x[/tex] does not equal to [tex]0[/tex], then [tex]x[/tex] must equal to [tex]0[/tex]:

[tex]\boxed {x = 0}[/tex]

Answer:

[tex]d = \sqrt{13}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(7-4)^2+(-3-(-1))^2}[/tex]

[tex]d = \sqrt{(3)^2+(-3+1)^2}[/tex]

[tex]d = \sqrt{9+(-2)^2}[/tex]

[tex]d = \sqrt{9+4}[/tex]

[tex]d = \sqrt{13}[/tex]

Answer:

Correct options are:

a) ( 0 , 445 )

d) ( 118 , 209 )

e) ( 172 , 101 )

Step-by-step explanation:

A nickel is worth 5 cents $0.05

A dime is worth 10 cents = $0.10

The relationship between the numbers of dimes and nickels, and the amount of money in dollars is represented by the equation 0.10d+0.05n=22.25. Select the THREE values (d,n) that could be solutions to the equation.

a) ( 0 , 445 )

b) ( 0.50 , 435 )

c) ( 233 , 21 )

d)( 118 , 209 )

e)( 172 , 101 )

Verifying the options

a) ( 0 , 445 )

0.10d+0.05n=22.25.

= 0.10(0) + 0.05(445) = 22.25

= 22.25 = 22.25

Options a) is correct

b) ( 0.50 , 435 )

0.10d+0.05n=22.25.

= 0.10(0.50) + 0.05(435) = 22.25

= 21.8 ≠ 22.25

Option b is incorrect

c) ( 233 , 21 )

0.10d+0.05n=22.25.

= 0.10(233) + 0.05(21) = 22.25

= 24.35 ≠22.25

Option c is incorrect

d) ( 118 , 209 )

0.10d+0.05n=22.25.

= 0.10(118) + 0.05(209) = 22.25

= 22.25 = 22.25

Option d) is correct

e) ( 172 , 101 )

0.10d+0.05n=22.25.

= 0.10(172) + 0.05(101) = 22.25

= 22.25 = 22.25

Option e) is correct

The answer to the equation is  [tex]x=\frac{2}{7}[/tex]

First, you must add 12 on each side

[tex]14x=16-42x[/tex]

Then, you add 42x on each side

[tex]56x=16[/tex]

Finally, divide each side by 56

[tex]x=\frac{2}{7}[/tex]

The value of x = 2/7 which makes the equation 14x - 12 = 4 - 42x true.

A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.

14x - 12 = 4 - 42x

14x + 42x = 4 + 12

56x = 16

x = 2 / 7

Therefore, The value of x = 2/7 which makes the equation 14x - 12 = 4 - 42x true.

Answer:

e/c=m

Step-by-step explanation:

To solve for "m" you need to isolate the variable. Since m is being multiplied by c you need to do the opposite operation, division. The Division Property of Equality tells us that we are allowed to divide the equation by any number as long as we divide it by both sides. So e/c=mc/c, then the c's cancel out, and your final answer is e/c=m.

Work Shown:

2(3c+3) < 6c+9

6c+6 < 6c+9 .... distribute

6c+6-6c <6c+9-6c .... subtract 6c from both sides

6 < 9 ... note the c terms go away entirely

We're left with a statement that is always true since 6 is always less than 9 regardless of what value of c we pick. So there are infinitely many solutions. Any real number can replace c to get a true statement.

Answer:

y = 7/2x - 20

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original slope.

-2/7 -> 7/2

Find the new y-intercept.

y = 7/2x + b

-6 = 7/2(4) + b

-6 = 14 + b

-20 = b

y = 7/2x - 20

Step-by-step explanation:

Simplify the expression

Answer:

The constant of proportionality is basically just the slope, so the answer is 1/6.

Step-by-step explanation:

Count how many Y units it goes up to get the the black point  from (0,0) (the origin). You go up 1 unit to go 6 units to the right meaning the slope is 1/6.

That is the rise over run technique and there are many others, such as point slope form, and y2-y1 over x2-x1.

Wait a minute - sorry I misunderstood the question lol

The equation of the parabola is y = -1/9(x- 1)^2 - 6.

If a quadratic equation is written in the form

y=a(x-h)^2 + k

then it is called to be in vertex form.

It is given that the equation passes through (4 -7) and has vertex (1 -6) in vertex form will be;

y=a(x-h)^2 + k

Since the vertex is at (1, -6), we can write the equation as

y = a(x- 1)^2 - 6

Also, since the parabola passes through (4, -7), we can find the value for a,

-7 =  a(4 - 1)^2 - 6

-7 = 9a - 6

a = -1/9

Hence, the equation of the parabola is

y = -1/9(x- 1)^2 - 6
