Lisa washes dishes at the local diner. She can wash 4 dishes every minute. What is the algebraic equation to express the function of the total number of dishes Lisa washes?

Answer:

about like 4-5

Step-by-step explanation:

its 4 or 5

The solution to the equation 12 - b = 12.5 is b = -0.5, which is determined by substituting -0.5 for 'b' in the equation, it will satisfy the equality and make both sides of the equation equal.

The equation is given as follows:

12 - b = 12.5

To solve the equation 12 - b = 12.5, we have to isolate the variable 'b' on one side of the equation.

First, we can subtract 12 from both sides to get rid of the constant term on the left side:

12 - b - 12 = 12.5 - 12

Simplifying, we have:

-b = 0.5

Next, we can multiply both sides of the equation by -1 to solve for 'b' by isolating it:

(-1)(-b) = (-1)(0.5)

This yields:

b = -0.5

Therefore, the solution to the equation 12 - b = 12.5 is b = -0.5.

x = y² - 7 is the simplified inverse equation of the equation y = x² - 7.

Inverse function is a function which reverse one function to another.

If a function f takes the variable x to y, then the inverse of a function must takes y to x.

To get the inverse of the function, we have to interchange the variables.

Given equation is y = x² - 7

Now interchange the variable x to y and y to x,

we get  x = y² - 7

Hence, the required equation is x = y² - 7

Answer:

Use the app Microsoft Maths is very simple

Answer:

(12, 6 )

Step-by-step explanation:

Given the 2 equations

\(\frac{x}{3}\) - \(\frac{y}{2}\) = 1 ( multiply through by 6 to clear the fractions )

2x - 3y = 6 → (1)

\(\frac{x}{4}\) - \(\frac{y}{3}\) = 1 ( multiply through by 12 to clear the fractions )

3x - 4y = 12 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x - 9y = 18 → (3)

- 6x + 8y = - 24 → (4)

Add (3) and (4) term by term to eliminate x

0 - y = - 6

- y = - 6 ( multiply both sides by - 1 )

y = 6

Substitute y = 6 into either of the 2 equations and solve for x

Substituting into (1)

2x - 3( 6) = 6

2x - 18 = 6 (add 18 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

solution is (12, 6 )

If you start at (0,-4) and you move left 1 unit and right 4 units, you end at (3, -4)

From the question, we have the following parameters that can be used in our computation:

Start = (0, -4)

Also, we have

You move left 1 unit and right 4 units

Mathematically, this can be expressed as

(x, y) = (x - 1 + 4, y)

Answer:

60°

Step-by-step explanation:

In similar triangles, the corresponding angles are congruent.

          ∠O = R

          O = 70°

In ΔOMN,

      ∠O + ∠M + ∠N = 180     {Angle sum property of triangle}

       70 + 50 + Ф    = 180

               120 + Ф  = 180

Subtract 120 from both sides,

                        Ф  = 180 - 120

                         Ф = 60°  

Using an algebraic equation to represent the word problem, the smallest integer is 1

This is a way of representing mathematical problems with words. To solve this, we have to use algebraic equations or expressions.

The number of pounds of each alloy he must use are: 49.33 of 32% aluminum and 4.67 of 44% Alloy

X = amount of alloy 1

Y = amount of alloy 2

Thus:

X + Y = 54

X = 54 - Y

0.32X + 0.44Y = 0.36 * 54

0.32X + 0.44Y = 19.44

Plugging in 54 - Y for X gives us:

0.32(59 - Y) + 0.44Y = 19.44

18.88 - 0.32Y + 0.44Y = 19.44

0.12Y = 19.44 - 18.88

Y = 0.56/0.12

Step-by-step explanation:

The value of the functions are,

f + g = x² - 8x + 1

f - g = x² - 10x - 1

fg = x³-8x²-9x

The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.

Given functions are f(x) = x² − 9x and g(x) = x + 1. The values will be calculated as,

f + g =  x² − 9x +  x + 1

f + g = x² − 8x  + 1

f - g = x² − 9x - x - 1

f - g =  x² − 10x - 1

f x g = (x² − 9x) x (x + 1)

f x g = (x³ +x ² - 9x² -9x)

f x g = x³ - 8x² - 9x

Therefore, the value of the functions are, f + g = x² - 8x + 1, f - g = x² - 10x - 1, and fg = x³-8x²-9x.

The domain of the relation of the graph representing a relation where x represents the independent variable and y represents the dependent variable is {−4, −2, 0, 3, 5}.

The domain of a relation is the set of all possible input values (independent variable) for which the relation is defined.

Looking at the given points, the x-coordinates are -4, -2, 0, 3, and 5. So, the possible input values are -4, -2, 0, 3, and 5.

Answer:

Step-by-step explanation:

The given options, the only value greater than 1 is 1.003. Therefore 0.886, which is less than 1 and makes the inequality true.

The given number sentence is 5.3 × > 5.3, where we need to find the scaling factor that makes the inequality true. To do this, we can divide both sides of the inequality by 5.3. This gives us:

5.3 × x > 5.3 ÷ 5.3 × k

We need to find the value of k that makes the inequality true. Simplifying the right-hand side of the equation, we get:

5.3 ÷ 5.3 × k = k × 1 = k

Substituting this into our equation, we get:

5.3 × x > k

We know that 5.3 × 1 = 5.3, which means that k must be greater than 1 to satisfy the inequality. Among the given options, the only value greater than 1 is 1.003. However, this value would make the inequality too large, so it is not the correct answer.

The correct answer is therefore 0.886, which is less than 1 and makes the inequality true.
