Answer:

The Scuba diver is 21 feet below sea level

Step-by-step explanation:

I took the test and it was this

The position of the scuba diver relative to sea level is 17 feet below surface.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =

Given that, A fish swims 4 feet directly above a scuba diver. The fish suddenly dives to double its depth under the surface of the ocean. The fish dives to a depth of −34 feet.

Let the position of the fish is at x feet from surface of the ocean

Therefore, the position of scuba diver = x-4

Since, the fish dives double its depth, therefore, new position of diver = 2(x-4)

According to question,

2(x-4) = -34

2x-8 = -34

2x = -26

x = -13

Therefore, the position of the diver = -13-4 = -17

Hence, the position of the scuba diver relative to sea level is 17 feet below surface.

[tex]\text{Hence the area of square 3 is 400 units}^2.[/tex]

Answer:

  400 square units

Step-by-step explanation:

The side length of square 1 is 1/4 of its perimeter, so is 100/4 = 25 units. The area of square 1 is the square of the side length, so is 25² = 625 square units.

The area of square 3 is the difference in the areas of squares 1 and 2. This is due to the Pythagorean theorem.

  area 3 = area 1 - area 2

  area 3 = 625 -225

  area 3 = 400 . . . . square units

Answer:

-4

Step-by-step explanation:

The equation is in slope-intercept format, y=mx+b. The coefficient in front of the x is the slope as represented by the letter m.

Answer:

Slope = -4

Step-by-step explanation:

The slope can be identified by looking at the coefficient next to the variable, x. In this instance, the coefficient is -4. Therefore, the slope is -4.

c = 1 > 7 =

According to reliable sources.

Answer:

C > 9

Step-by-step explanation:

First Subtract 1 from both sides

2c/3 + 1 -1 > 7-1

= 2c/3 > 6

Now Multiply bith the sides by 3

3 × 2c/3 > 6 × 3

= 2c > 18

Now Divide both sides by 2

2c/2 > 18/2

= c > 9

Answer:

B. y = 2x² + 5x - 3

Step-by-step explanation:

[tex]4x^2+10x-2y=6\\\\4x^2+10x-2y-4x^2-10x=6-4x^2-10x\\\\-2y=-4x^2-10x+6\\\\\frac{-2y}{-2}=\frac{-4x^2-10x+6}{-2}\\\\y=2x^2+5x-3[/tex]

The result when the equation is solved for y is y = 2x² + 5x - 3.

To solve the equation 4x² + 10x - 2y = 6 for y, follow these steps:

Step 1: Move all terms containing y to one side of the equation:

4x² + 10x - 6 = 2y

Step 2: Divide both sides of the equation by 2 to isolate y:

(4x² + 10x - 6) / 2 = y

Step 3: Simplify the right side of the equation:

y = 2x² + 5x - 3

So, the result when the equation is solved for y is y = 2x² + 5x - 3.

Answer: 486 glasses of water in 9 weeks

Step-by-step explanation:

54 X 9 = 486

Or you could add 54 to itself 9 times then you will get 486

When adding, you only add the numerators. The denominator stays the same (Assuming the denominators are the same number). If not, then you will have to find a common denominator first. IN this case, the denominator is already the same. Add the numerator

2/3 + 2/3 = 4/3

Note that the answer gotten is an “improper fraction”, because the numerator is greater than the denominator. Simplify.

4/3 = 3/3 + 1/3

Divide: 3/3 = 1

1 + 1/3 = 1 1/3

1 1/3 is your mixed fraction answer (4/3 for improper fraction answer)

Answer:

not a direct variation

Step-by-step explanation:

x = (y-2)/9 is also x = y/9 - 2/9

we can convert this into slope-intercept form

y/9 = x + 2/9

y = 9x + 2

this equation is a straight line and is constantly going up BUT the y-intercept is not 0 so it is not a direct variation

the direct variation equation y = kx does not have a b or a y-intercept

Answer:

Hope this helps! :)

The unit price of peach would be $0.14.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a 9-ounce can of peaches sells for $1.26.

9-ounce can of peaches sells for $1.26.

Then -

1 ounce of peach will cost = (1.26/9) = $0.14

Therefore, the unit price of peach would be $0.14.

You have two variables, and only one condition. It means you have infinite solutions of the form [tex](t; t^2+5t-7)[/tex]. Technically correct, probably not what you want to know.

If you wanted to know if and where the RHS crosses the x axis, the points are the solution to

[tex]x^2+5x-7= 0 \rightarrow x=\frac12(-5\pm\sqrt{25+28})\\x_1= \frac12(\sqrt{53}-5); x_2=-\frac12(\sqrt{53}+5)[/tex]

If you wanted the graph it's a parabola passing through the two points we just found, (0;-7), and with an axis of equation [tex]x=-\frac52[/tex].

b is the answer of the question because it is the only answer

Usando un sistema de ecuaciones, se encuentra que Rocío y Rafael tienen 23 barcos y 34 aviones.

Para el sistema, consideramos que:

Situviéramos once barcos más, tendríamos el  mismo número de barcos y aviones, o sea:

[tex]x + 11 = y[/tex]

[tex]y = x + 11[/tex]

Pero si tuviéramos  doce aviones más, tendríamos el doble de aviones que de barcos, o sea:

[tex]y + 12 = 2x[/tex]

De el primer ecuación, [tex]y = x + 11[/tex], por eso:

[tex]y + 12 = 2x[/tex]

[tex]x + 11 + 12 = 2x[/tex]

[tex]x = 23[/tex]

[tex]y = x + 11 = 23 + 11 = 34[/tex]
