Step-by-step explanation:

Step 1: -x^2 is -1 because x is always 1.

Now that you found your first step take -1x+10=6. You're going to subtract 10 from both sides which leaves you with a sum of -4. So -1x= -4 now divide -4/-1x which gives you a positive number.

Answer:

x = -2 or 2

Step-by-step explanation:

-x² + 10 = 6

Move everything to one side.  I suggest moving the left side to the right so that the leading coefficient becomes positive.

0 = x² − 4

Factor the difference of squares:

0 = (x − 2) (x + 2)

Set each factor to 0 and solve.

x − 2 = 0

x = 2

x + 2 = 0

x = -2

Therefore, the solution is x = -2 or 2.

A Staghorn Coral can grow as much as 3.35 feet in 5 years under ideal conditions, assuming it grows at a fixed rate of 0.67 foot per year.

The question asks us to find out how much a Staghorn Coral, a type of branching coral, can grow in 5 years. Each year, the coral can potentially increase its size by 0.67 foot. To figure this out, we would use multiplication, a basic arithmetic operation.

First, we need to multiply the annual growth rate (0.67 foot) by the number of years (5). So, 0.67 * 5 equals 3.35 feet. This signifies that the Staghorn Coral can grow as much as 3.35 feet over the course of five years under optimal conditions.

Therefore, a Staghorn Coral can potentially add 3.35 feet to its branches during a 5 year span if it grows at the rate of 0.67 foot per year.

Answer:

For [tex]x^2 - 4 = 0[/tex], x  = 2, or x = - 2.

Step-by-step explanation:

Here, the given expression is :

[tex]x^2 - 4 = 0[/tex]

Now, using the ALGEBRAIC IDENTITY:

[tex]a^2 - b^2 = (a-b)(a+b)[/tex]

Comparing this with the above expression, we get

[tex]x^2 - 4 = 0  = x^2 - (2)^2 = 0\\\implies (x-2)(x+2) = 0[/tex]

⇒Either (x-2) = 0 , or ( x + 2) = 0

So, if ( x- 2)   = 0 ⇒ x =  2

and if ( x + 2) = 0   ⇒ x = -2

Hence, for [tex]x^2 - 4 = 0[/tex], x  = 2, or x = - 2.

Answer:

Step-by-step explanation:

[tex]x^2-4=0\qquad\text{add 4 to both sides}\\\\x^2-4+4=0+4\\\\x^2=4\iff\sqrt{x^2}=\sqrt4\\\\|x|=2\Rightarrow x=\pm2[/tex]

Answer:

(- 5, 3 )

Step-by-step explanation:

Given the 2 equations

y = - 8x - 37 → (1)

x + 3y = 4 → (2)

Substitute y = - 8x - 37 into (2)

x + 3(- 8x - 37) = 4 ← distribute and simplify left side

x - 24x - 111 = 4

- 23x - 111 = 4 ( add 111 to both sides )

- 23x = 115 ( divide both sides by - 23 )

x = - 5

Substitute x = - 5 into (1) for corresponding value of y

y = - 8(- 5) - 37 = 40 - 37 = 3

Solution is (- 5, 3 )

Answer:

x = -5, y = 3 or you can write it as (-5, 3).

Step-by-step explanation:

y=-8x – 37

x+3y=4

From the second equation  x = 4 - 3y, so substituting in equation 1:

y = -8(4 - 3y) - 37

y = -32 + 24y - 37

-23y =  -69

y = 3

Now plug y = 3 into equation 1:

3 = -8x - 37

-8x = 40

x = -5.

Answer:

(2, 6)

Step-by-step explanation:

Because 8(2)-2(6)=16-12=4.

The ordered pair of the equation 8x - 2y = 4 is (2,6).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the equation is 8x - 2y = 4. The ordered pair will be calculated as,

8x - 2y = 4

( 8 x 2 ) - ( 2 x 6) = 4

16 - 12 = 4

4 = 4

Therefore, the ordered pair of the equation 8x - 2y = 4 is (2,6).

The measure of the three angles are 120°, 20° and 40°

Step-by-step explanation:

Let

x ----> the measure of the first angle

y ---> the measure of the second angle (smallest angle)

z ---> the measure of the third angle

Remember that

The sum of the angles in a triangle must be equal to 180 degrees

so

[tex]x+y+z=180[/tex] ----> equation A

[tex]x=y+100[/tex] -----> equation B

[tex]z=2y[/tex] ------> equation C

solve the system by substitution

substitute equation B and equation C in equation A

[tex](y+100)+y+(2y)=180[/tex]

solve for y

[tex]4y+100=180[/tex]

[tex]4y=180-100[/tex]

[tex]4y=80[/tex]

[tex]y=20\°[/tex]

Find the value of x

[tex]x=y+100[/tex]  ---- [tex]x=20+100=120\°[/tex]

Find the value of z

[tex]\frac{ d^{2} y}{dx^{2} } = -10[/tex]

Step-by-step explanation:

Concept : We have to differentiate the given equation twice and then put the values of x and y at the given point.

The given point is (2,-5).

Given    xy - y = -5

Differentiating both sides,

[tex] x \times \frac{dy}{dx} + y - \frac{dy}{dx}[/tex] = 0

Substitute (x,y) as (2,-5)

[tex]2 \times \frac{dy}{dx} -5 - \frac{dy}{dx}[/tex] = 0

[tex]\frac{dy}{dx} = 5[/tex]

Differentiating again, we get

[tex]\frac{dy}{dx} + x \times \frac{ d^{2} y}{dx^{2} } + \frac{dy}{dx} - \frac{ d^{2} y}{dx^{2} } = 0[/tex]

Substitute values of x , y and \frac{dy}{dx} ,

[tex]5 + 2 \times \frac{ d^{2} y}{dx^{2} } + 5 - \frac{ d^{2} y}{dx^{2} } = 0[/tex]

The height of the rock is 15 mm.

Step-by-step explanation:

Given : Cristian put a large rock on the bottom of the terrarium he made for his pet turtle.

To find : How high is the rock?

Solution :

The rock is a right rectangular prism 10 cm wide by 12 cm long.

Let the height be 'h'.

The volume of the right rectangular prism is [tex]V=L\times B\times H[/tex]

i.e. [tex]V=10\times 12\times h[/tex]

[tex]V=120h[/tex]

The rock displaces 1800 cm³ of water.

i.e. The volume of the right rectangular prism is equal to the rock displaces of water.

So, [tex]120h=1800[/tex]

[tex]h=\frac{1800}{120}[/tex]

[tex]h=15[/tex]

Therefore, the height of the rock is 15 mm.

The exact answer is going to be equal to 15mm

The possible values of tutoring hours are 12 hours, 13 hours, 14 hours, 15 hours.

Given that, Nicole is working two summer jobs, making $10 per hour babysitting and making $20 per hour tutoring.  

In a given week, she can work at most 17 total hours and must earn a minimum of $250.  

Nicole worked 2 hours babysitting, then we have to determine all possible values for the number of whole hours tutoring that she must work to meet her requirements.  

Now, as she worked for 2 hours of babysitting, she will get 2 x $10 = $ 20  

Now, after this, she can work at most (17 - 2) = 15 hours for tutoring and she has to earn minimum of 250 – 20 = $230

Now, let the number of hours she tutored be "n"

Then, from above cases n ≤ 15  

And n x $20 ≥ 230

n ≥ 11.5  

Here we have to cases,  n ≥ 11.5 and n ≤ 15

So, the possible list of n values will be 12, 13, 14, 15

Hence, the possible values of tutoring hours are 12 hours, 13 hours, 14 hours, 15 hours.

The possible values for the number of whole hours tutoring that Nicole must work are: {12, 13, 14, 15} .

Given:

- Nicole can work at most 17 total hours: [tex]\( b + t \leq 17 \)[/tex].

- Nicole must earn a minimum of $250: [tex]\( 10b + 20t \geq 250 \)[/tex].

Nicole worked 2 hours babysitting, so ( b = 2 ).

Substituting ( b = 2 ) into the inequality [tex]\( b + t \leq 17 \)[/tex], we get:

[tex]\[ 2 + t \leq 17 \]\[ t \leq 17 - 2 \]\[ t \leq 15 \][/tex]

Now, let's find the minimum number of hours tutoring that Nicole must work to meet her requirements:

[tex]\[ 10(2) + 20t \geq 250 \]\[ 20 + 20t \geq 250 \]\[ 20t \geq 250 - 20 \]\[ 20t \geq 230 \]\[ t \geq \frac{230}{20} \]\[ t \geq 11.5 \][/tex]

Since Nicole must work a whole number of hours tutoring, the minimum number of hours tutoring she must work is 12 hours.

The distance from home to second base in a slow pitch softball diamond is approximately 87.68 feet. This calculation is achieved through the use of the Pythagorean theorem, which utilizes the square lengths of the diamond sides to calculate the diagonal path between the bases.

The distance from home to second base in a slow pitch softball diamond can be calculated using the Pythagorean theorem, as the path forms a right triangle. The side lengths of the diamond are 62 ft, so we can use these as the legs of our right triangle. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, it's a^2 + b^2 = c^2, where c is the distance we want to find.

So, the calculation will be √((62ft)^2 + (62ft)^2). Simplifying this gives √(3844ft^2 + 3844ft^2), which is √7688ft^2. Which gives us approximately 87.68 ft. So, the distance from home to second base is approximately 87.68 feet.

To find the distance from home to second base on a slow pitch softball diamond, use the Pythagorean theorem to calculate the diagonal of the square. With each side being 62 feet, the distance comes out to approximately 87.7 feet.

How to Find the Distance from Home to Second Base

In a slow pitch softball diamond, the bases form a square with each side measuring 62 feet.

We must compute the diagonal for the square in order to get the distance between home plate and second base.

This can be done using the Pythagorean theorem.

Step-by-Step Solution

Label the sides of the square. Each side is 62 feet.

Recall the Pythagorean theorem formula: a² + b² = c², where 'a' and 'b' are the legs of a right triangle, and 'c' is the hypotenuse (which, in this case, is the diagonal).

Here, both 'a' and 'b' are 62 feet because the square’s sides are equal.

→ Substitute the values into the formula: 62² + 62² = c²

→ Calculate the squares: 3844 + 3844 = c²

→ Combine the values: 7688 = c²

→ Take the square root to find 'c': c = √7688

The diagonal (distance from home to second base) is approximately 87.7 feet.

Therefore, the distance from home to second base is about 87.7 feet.

Let's first try to eliminate wrong options.

If we observe carefully, we can say that option 2 that is [tex]\frac{3}{2}=\frac{x}{y}[/tex] is not correct as [tex]\frac{x}{y}[/tex] must be equal to [tex]\frac{2}{3}[/tex] and not [tex]\frac{3}{2}[/tex]

Lets now modify given expression that is:

[tex]\frac{2}{3}=\frac{x}{y}[/tex]

On adding 1 to both sides we get

[tex]\frac{2}{3}+1=\frac{x}{y}+1[/tex]

[tex]=>\frac{2+3}{3}=\frac{x+y}{y} \text { which is same as third option. }[/tex]
