Answer:

x = ± 2

Step-by-step explanation:

Given

3x² - 6 = 10 - x² ( add x² to both sides )

4x² - 6 = 10 ( add 6 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

Answer:

x ≤ 8

Step-by-step explanation:

The number of ounces of water x that Will could have poured into each cup is 8 or less than 8. by solving through inequality.

Inequality is just like equation which expresses relationship between two or more variables but it is in greater than or less than form. It is just like:

x+ y<c.

Let the capacity of each cup be x.

According to question

16x+16<=144

16x<=144-16

16x<=128

x<=8.

Hence the number of ounces of water that Will could have poured into each cup is 8 or less than 8.

Answer:

x+10/

Step-by-step explanation:

Quotient of 4 =divide by 4

a number increased by 10= x+10

The statement 'Quotient of 4 and a number increased by 10' can be translated into a mathematical expression as 4/x + 10, where x is the unknown number.

If you mean the quotient of 4 and a number, we call that unknown number 'x'. So, the quotient of 4 and a number x is written as 4/x. Then, according to your question, that quotient is increased by 10. In mathematics, 'increased by' typically equates to the operation of addition. Thus, the entire expression translates into mathematical terms as 4/x + 10.

Answer:

k = 4

Step-by-step explanation:

The constant of proportionality is found by starting with y = kx, then finding k.

We can just use one point (such as the first one, (1,4) ) and substitute these values of x and y into the equation  y = kx, to get:

4 = k x1

k = 4.

So y = 4x

(we can also check that all the other points also satisfy this equation - which they do, as each y value is 4 times the corresponding x value)

Answer: 19/28

Step-by-step explanation: Notice that 1/4 and 3/7 are unlike fractions. Our first step when adding unlike fractions is to get a common denominator.

The common denominator of 4 and 7 will be the least common multiple of 4 and 7 which is 28.

To get a 28 in the denominator of 1/4, we multiply the numerator and the denominator by 7 which gives us 7/28.

To get a 28 in the denominator of 2/7, we multiply the numerator and the denominator by 4 which gives us 12/28.

Now to add like fractions or fractions that have the same denominator, we simply add the numerators and keep the original denominator.

So here, we have 7 + 12 which is 19 and we put this over our original denominator which is 28.

So, 1/4 + 3/7 = 19/28.

You need to find "k", by isolating/getting "k" by itself in the equation

16.3k + 19.2 + 7.5k = -64.1     First combine like terms, 16.3k and 7.5k

23.8k + 19.2 = -64.1       Subtract 19.2 on both sides

23.8k = -83.3       Divide 23.8 on both sides to get "k" by itself

k = - 3.5

Answer:

Eqn of the problem: 2(3x + x) = 30

Solution: Width = 3.75 inches  and Length= 11.25 inches

Step-by-step explanation:

We are given;

We are required to represent the equation of the problem;

The formula for getting the perimeter of a rectangle is;

Perimeter = 2 (l+w)

In this case;

2(3x + x) = 30

Therefore;

The equation for the problem is;

2(3x + x) = 30

8x=30

Thus;

8x = 30

  x = 3.75 inches

 3x = 11.25 inches

Hence, the with is 3.75 inches while the length is 11.25 inches

Answer:

The solution is (2, -2)

Step-by-step explanation:

Let's find out the solution of the system:

10x − 2y = 24

6x + 2y = 8

Describing x in terms of y in the first equation, this way:

10x − 2y = 24

10x = 24 + 2y

x = 2 * (12 + y)/10 (Dividing by 10 at both sides)

x = (12 + y)/5 (Simplifying)

Solving for y in the 2nd equation:

6x + 2y = 8

6 * (12 + y)/5 + 2y = 8

(72 + 6y)/5 + 2y = 8

72 + 6y + 10y = 40 (Multiplying by 5 at both sides)

16y = 40 - 72

16y = -32

y = -2

Solving for x in the 1st equation:

10x − 2y = 24

10x - 2 * -2 = 24

10x + 4 = 24

10x = 24 - 4

10x = 20

x = 20/10

x = 2

The solution is (2, -2)

The weight of 4 screws is 0.1 ounces

Step-by-step explanation:

The problem can be solved by setting up a proportion.

In fact, we know that:

- The weight of 80 screws is 2 ounces

- So we want to find the weight of 4 screws

We can write the following proportion:

[tex]\frac{80}{2}=\frac{4}{x}[/tex]

where

x is the weight of 4 screws

Solving the equation, we find:

[tex]x=\frac{4\cdot 2}{80}=0.1[/tex]

So, the weight is 0.1 ounces.

Answer:

x² + y² + 2y - 1 = 0

Step-by-step explanation:

The general form of the equation for the circle:

x² + y² + ax + by + c = 0

Where: a, b and c are constants.

For the given equation:

x² + (y + 1)² = 2

∴ x² + (y + 1) (y+1) = 2

∴ x² + y² + 2y + 1  = 2  ⇒ subtract 2 from both sides

∴ x² + y² + 2y + 1 - 2 = 2 - 2

∴ x² + y² + 2y - 1 = 0

So, the general form of the equation for the circle:

x² + y² + 2y - 1 = 0
