Matematicas alguien me explica cómo hago esto 2 • 4 •5

Answers

Answer 1

Answer: ¡Claro! Para multiplicar esos números, simplemente tienes que multiplicarlos uno por uno.
Entonces, 2 • 4 es igual a 8, y luego 8 • 5 es igual a 40. ¡Así que el resultado es 40!

What is the equation for a line that passes through the points (-5,-4) and (10,14)?

Answers

Answer:

y=6/5x+2

Step-by-step explanation:

1.find the slope(m)

m=y2-y1/x2-x1

m=14-(-4)/10-(-5)

m=14+4/10+5

m=18/15

m=6/5

y-y1=m(x-x1)

y-(-4)=6/5(x-(-5))

y+4=6/5(x+5)

y+4=6/5x+30/5

y=6/5x+30/5-4

y=6/5x+10/5

y=6/5x+2

True or False. When graphing the inequality y>3x+2 the line drawn would be a solid line.

Answers

Answer:

False

Step-by-step explanation:

Since the inequality uses the greater than symbol >

Then the line drawn should be a broken line.

If the inequality had ≥ ( greater than or equal to )

Then the line would be solid.

the guy above is correct

The answer is: False

a box with no top is constructed from a 10 inch x 12 inch piece of cardboard by cutting out congruent squares from each corner of the cardboard and then folding the resulting tabs. We determined the volume of that box (in cubic inches) is given by V(x) = 4x³ - 44x² + 120x where x denotes the length of the side of the square which is removed from each corner (in inches), 0 < x < 5. Solve the inequality V(x)≥80 analytically and interpret your answer in the context of that example.

Answers

Answer:

$To solve the inequality $V(x) \geq 80$, we'll first set up the inequality and then find the values of $x$ that satisfy it.The inequality is $4x^3 - 44x^2 + 120x \geq 80$.Let's simplify it further:$4x^3 - 44x^2 + 120x - 80 \geq 0$.Now, we need to find the values of $x$ that make this inequality true.We can start by factoring the expression:$4(x^3 - 11x^2 + 30x - 20) \geq 0$.$

$Now, let's factor the cubic polynomial inside the parentheses:$x^3 - 11x^2 + 30x - 20 = (x - 2)(x - 5)(x - 2)$.Now, the inequality becomes:$4(x - 2)(x - 5)(x - 2) \geq 0$.To determine the intervals where this inequality is satisfied, we can use a sign chart. We'll consider the values of $x$ that make each factor and the whole expression positive or negative.$

$1. $x - 2$ is positive for $x > 2$ and negative for $x < 2$.\n2. $x - 5$ is positive for $x > 5$ and negative for $x < 5$.\n3. $x - 2$ is positive for $x > 2$ and negative for $x < 2$.Now, consider the overall sign of the expression $4(x - 2)(x - 5)(x - 2)$:- Positive when all three factors are positive (i.e., $x > 5$).- Negative when exactly one factor is negative (i.e., $2 < x < 5$).- Positive when all three factors are negative (i.e., $x < 2$).$

$So, the solution to the inequality $V(x) \geq 80$ is:\[x < 2 \text{ or } 2 < x < 5.\]$

Step-by-step explanation:

In the context of the example, this means that the side length of the square removed from each corner must be less than 2 inches or between 2 and 5 inches for the volume of the box to be greater than or equal to 80 cubic inches. This helps determine the range of valid values for

x to achieve the desired volume for the box.

Final Answer:

The solution to the inequality V(x) ≥ 80 is x ≥ 3.5 inches.

Explanation:

To solve the inequality V(x) ≥ 80, we set the equation 4x³ - 44x² + 120x ≥ 80 and simplify. This simplifies to x³ - 11x² + 30x - 20 ≥ 0, which can be factored as (x - 3.5)(x - 2)(x - 2.857) ≥ 0. Since x represents the side length of the squares removed from the corners, it cannot be negative, so we focus on the values of x that make the expression on the left side of the inequality greater than or equal to zero. This leads us to the solution x ≥ 3.5 inches.

In the context of the example, when the side length of the squares removed from each corner is 3.5 inches or larger, the resulting box has a volume greater than or equal to 80 cubic inches. This means that to achieve a box with a volume of at least 80 cubic inches, you need to remove squares with sides of at least 3.5 inches.

HELP PLSS WHICH ONE IS IT!!Question 7 (3.03): Use the graph representing bacteria decay to estimatethe domain of the function and solve for the average rate of change across
the domain.

Answers

Answer:The domain of a function is the set of input values of the function.

The domain of the function is: [0,18]

The average rate of change across the domain is -3.33

Step-by-step explanation:From the graph, we have the following highlights.

The graph starts from the origin

The graph ends at x = 18

So, the domain of the function is: [0,18]

The average rate of change is calculated as:

From the graph, we have:

So, we have:

This gives

Hence, the average rate of change across the domain is -3.33

Answers

Okay so you split 9ab + 12ax - 6b - 8x
             into two 2-term polynomials
              + 12ax + 9ab   and     - 6b - 8x
             doesn't look that good to me so lest try other one :
             9ab + 12ax   and     - 6b - 8x
             looks good for now

            Pull out from each binomial separately
             9ab + 12ax   =   3a • (3b + 4x)
              - 6b - 8x   =    - 2 • (3b + 4x)

           Add up to arrive at the desired factorization so now you have
             (3a - 2) • (3b + 4x)
