Answer:

y - 2 = [tex]\frac{1}{3}[/tex](x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = [tex]\frac{1}{3}[/tex] and (a, b) = (3, 2), thus

y - 2 = [tex]\frac{1}{3}[/tex](x - 3) ← in point- slope form

We want to find the equation of a line in the point-slope form, such that we know the slope and a point on the line.

The line will be: y - 2 = (1/3)*(x - 3)

Let's see how to find that line:

We know that our line has a slope equal to 1/3, and that it passes through the point (3, 2).

First, a general line in the point-slope form is:

y - y₁ = a*(x - x₁)

Where a is the slope and (x₁, y₁) is the point on the line.

Then, by using that general form and the given information, we can see that our line is:

y - 2 = (1/3)*(x - 3)

Answer:

Step-by-step explanation:

Lines are considered to be perpendicular if the angle between at the point they intersect is 90°, or a right angle.

If you have the equations of two lines, you can determine if they are perpendicular by looking at their slope. For the slope-intercept form of a line,

[tex]y = mx + b[/tex]

[tex]m[/tex] is the slope of the line.

Two lines are considered perpendicular, if the slope of one line is [tex]m[/tex], and the slope of the other line is [tex]\frac{1}{-m}[/tex].

For example, if a line had a slope of 4, say [tex]y = 4x + 2[/tex], then a line that would be perpendicular to this line would have a slope of [tex]\frac{-1}{4}[/tex], say [tex]y = \frac{-1}{4} + 7[/tex].

Answer:

Step-by-step explanation:

Option A. All the real values of x where x < -1

Procedure

Solve the inequality:

(x -3)(x+1)>0

That happens in two cases.

1) When both factors >0

x-3>0 and x+1>0

x>3 and x >-1

The intersection is x >3

2) When both factors <0

x-3<0 and x+1<0

x<3 and x<-1

the intersection is x<-1.

We have obtained that the function is positive for the intervals  x < -1 and x > 3. But in one of those intervals the function is decresing and in the other is increasing.

You can recognize that the function given is a parabola and, because the coefficient of the quadratic term is positive, the parabola opens upward. Then the function is decreasing in the  first interval and increasing in the second interval.

The expression is simplified by dividing each term and exponent separately. After simplification, the expression becomes [tex]\(2x^{10}y^{12}\)[/tex], corresponding to option b.

To simplify the given expression [tex]\(\frac{60x^{20}y^{24}}{30x^{10}y^{12}}\)[/tex], we can simplify the numerator and denominator separately, then divide.

First, let's simplify the numerator:

[tex]\[ \text{Numerator: } 60x^{20}y^{24} \][/tex]

Now, let's simplify the denominator:

[tex]\[ \text{Denominator: } 30x^{10}y^{12} \][/tex]

Now, we divide the simplified numerator by the simplified denominator:

[tex]\[ \frac{60x^{20}y^{24}}{30x^{10}y^{12}} = \frac{60}{30} \times \frac{x^{20}}{x^{10}} \times \frac{y^{24}}{y^{12}} \\\[ = 2 \times x^{20-10} \times y^{24-12} \\\[ = 2 \times x^{10} \times y^{12} \][/tex]

[tex]\[ = 2x^{10}y^{12} \][/tex]

So, the expression equivalent to [tex]\( \frac{60x^{20}y^{24}}{30x^{10}y^{12}} \)[/tex] is:

b. [tex]\( 2x^{10}y^{12} \)[/tex]

The probable question may be:

Which expression is equivalent to 60x^(20)y^(24)/30x^(10)y^(12)?

a. 2x^2y^2

b. 2x^(10)y^(12)

c. 30x^2y^2

d. 30x^(10)y^(12)

The distributive property is a math concept that allows multiplication to be distributed over addition or subtraction. It does not directly apply to the expression 16 + 36, as there's no multiplication involved. However, for an expression with multiplication, such as 4(16 + 36), it would simplify to 208 using the distributive property.

The distributive property is a fundamental concept in mathematics that allows us to simplify expressions involving multiplication distributed over addition or subtraction. It states that for any numbers a, b, and c, the equation a(b + c) = ab + ac holds true. This property makes it easier to work out expressions without having to perform operations within parentheses first.

In the given expression 16 + 36, however, there's no multiplication being distributed over addition, thus the distributive property doesn't directly apply here. But if we are to apply the distributive property to a multiplication over an addition, such as 4(16 + 36), then we would use the distributive property to get 4*16 + 4*36, which simplifies further to 64 + 144 = 208.

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

its difficult to explain but I found that there is a 10.3%Tax so 10.3% of 93 is 9

The sales tax on the second item, which cost $93 before tax, would be approximately $8.99 based on the tax rate of the first item.

To determine the amount of sales tax on the second item, we first need to understand the rate of sales tax applied to the first item. The sales tax on the first item was $21 on a pre-tax cost of $217. So, the tax rate would be 21 divided by 217, which is approximately 0.0967, or 9.67%.

If we apply this tax rate to the second item, which costs $93 before tax, we get 93 times 0.0967, or $8.99. Therefore, the amount of sales tax on the second item would be approximately $8.99.

Step-by-step explanation:

4x^2-5y

Final answer:

The question involves using algebraic expressions to square a number by multiplying it by itself and then subtracting the product of another number multiplied by five. it could be represented as 4a2 - 5b.

Explanation:

The question involves understanding how to manipulate algebraic expressions with integers and variables. When we talk about raising a number to a power, such as squaring a number, we are multiplying that number by itself. For example, the exponent is '2' and the base is the number '5', so squaring it would give us 52 = 5x5 = 25. When we consider an equation involving the square of one number and the multiplication of another, we have to apply these rules of exponents and multiplication.

In mathematics, we often encounter expressions where we square a number by raising it to the power of '2'. This also applies to variables. For instance, (2x)2 = 4x2. Remember, whether numbers are positive or negative, squaring them will always give a positive result because multiplying two negative numbers yields a positive product.

If a question involves subtracting five times one number from four times the square of another number, it could be represented as 4a2 - 5b. Here, a is being squared while b is simply being multiplied by five.

To solve the inequality -4.4 ≥ 1.6x - 3.6, you first add 3.6 to both sides, then divide by 1.6, resulting in -0.5 ≥ x. This means all values less than or equal to -0.5 make the inequality true and the graphed solution involves a filled circle at -0.5 and shading to the left.

To find the solution set for the inequality -4.4 ≥ 1.6x - 3.6, we first need to solve the inequality. To do this, we can start by adding 3.6 to both sides of the inequality:

-4.4 + 3.6 ≥ 1.6x

-0.8 ≥ 1.6x

Now, we divide both sides of the inequality by 1.6 to solve for x:

-0.8 / 1.6 ≥ x

-0.5 ≥ x

This tells us that x can take on any value that is less than or equal to -0.5. To graph this on a number line, we would plot a filled circle on -0.5 to indicate that it is part of the solution set (x is equal to -0.5), and shade everything to the left of -0.5 to indicate that all those values are solutions since they are less than -0.5.
