the rate of change of a linear function is 4 what could be the two points on the line of this function

The number of books Sophia and her brother read is 32 and 8 respectively.

Given that,

The total number of books = 40 books

The number of books Sophia read = 4[The number of books Sophia's brother read]

Assuming that the number of books Sophia's brother read = a

So, the number of books Sophia read = 4a

Thus,

a + 4a = 40

Solving the equation further, we get:

5a = 40

a = 8

The number of books Sophia's brother read = 8 books

Hence, the number of books Sophia read = 32 books

Therefore, The number of books Sophia and her brother read is 32 and 8 respectively.

Any quantity of equal portions, or fractions, can be used to represent a whole. In standard English, the quantity of a specific size is stated as a fraction. 8, 3/4. Wholes also include fractions. In mathematics, numbers are represented as the numerator to denominator ratio. These are each integers in simple fractions. There is a fraction in the fraction or denominator of a difficult fraction. Because numerators and numerator and denominator of real fractions differ from one another. A fraction is a total that represents a portion of a whole. By dividing the whole to smaller components, you can assess it. For instance, 12 is employed to denote half of a number.

Here,

You'd get 18 osprey if: a. 2:3 b. 2/3 = 12/x; 

cross multiplying 2x would give you 36 x.

c. You'd have 20 bald eagles if you took the ratio of 2/3 to x/30 and multiplied it by three.

We can start solving the problem by using algebra. Let x be the total length of the movie in minutes. Then we know that:

1/3 of the movie is x/3 minutes.

1/5 of the movie is x/5 minutes.

We are told that Joshua watched 1/3 of the movie in the morning and had 1/5 of the movie left to watch at night. Therefore, we can set up the equation:

x/3 + y = x/5, where y is the length of the movie that Joshua watched at night.

We can then solve for y by isolating it on one side:

y = x/5 - x/3

We know that 1/3 + 1/5 = 8/15.

We can simplify by multiplying both sides of the equation by 15:

y = (8/15)*x = 8x/15

We can conclude that Joshua watched 8/15 or approximately 53.33% of the movie at night.

The area of a triangle with the base of 7 cm and the height of 12 cm is 42 square cm.

In the given question we have to find the area of a triangle with the base of 7 cm and the height of 12 cm.

The entire area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it equals half of the base times height, or A = 1/2bh. So, in order to calculate the area of a triangular polygon, we need to know its base (b) and height (h).

Area of Triangle = 1/2 ×b×h

Area of Triangle = 1/2 ×7×12

Area of Triangle = 7×6

Area of Triangle = 42 square cm

Hence, the area of a triangle with the base of 7 cm and the height of 12 cm is 42 square cm.

Slope is a measure of steepness of a line. In Algebra 1, It is how much the y-value changes when the x-value increases by 1.

y-intercept is the y-value of the line when it intersects with the y-axis, or the y-value of the line when the x-value of the line is 0.

This form is the most common form for expressing linear equations for graphing and is used when the slope and y-intercept is known.

Form

y = mx + b

Lets break it down. y and x stay as a variable when graphing is it only substituted for a constant when solving for x-intercept, etc.

m is the slope.

b is the y-intercept.

Q1

y = mx + b

y = 5x

Because 5 is the m value, the slope is 5.

Q2

y = mx + b

y = 3

Think about it. What cancels out any real value? Multiplying it by 0. If there is no coefficient behind the x, it means the slope is 0.

y = 0x + 3 = y = 3

Because 0 is the m value, the slope is 0.

When y is equal to a constant after solving, it is a horizontal line with the y-intercept of the constant it is equal to (in this case 3).

Q3

y = mx + b

x = 5

The slope is undefined.

When x is equal to a constant after solving, it is a straight vertical line with the x-intercept of the constant it is equal to (in this case 5). The slope is always undefined.

Answer: To solve a 3-step equation, you can follow these steps:

Simplify both sides of the equation, if necessary, by combining like terms.

Isolate the variable on one side of the equation.

Use inverse operations to solve for the variable.

Check your solution by substituting it back into the original equation.

Example:

Solve for x: 2x + 5 = 11

Subtract 5 from both sides of the equation: 2x = 6

Divide both sides of the equation by 2: x = 3

Check your solution by substituting x = 3 back into the original equation: 2(3) + 5 = 11

The solution is x = 3.

Step-by-step explanation:

The measure of angle x is 57.5 degrees. The measure of angle y is 122.5 degrees. The correct option is C.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

The measures of two supplementary angles total 180 degrees.

The measure of angle y is 65 degrees less than the measure of angle x.

Let the measure of angle y is m∠y.

And the angle measure of x is m∠x.

So,

m∠x + m∠y = 180°   {equation 1}

And according to the question,

m∠y = m∠x - 65°        {equation 2}

Substituting the value from equation 2 to equation 1,

2m∠x = 180 + 65

m∠x = 245/2

m∠x = 122.5°

And m∠y = 122.5 - 65

m∠y = 57.5°

Therefore, the angle measures are m∠x = 122.5° and m∠y = 57.5°.

Answer:

First, we need to simplify the expression by combining like terms. We have -4 + 3x^2-3 and -1. We can combine the like terms -4 and -1 to get -5.

Now, the expression can be rewritten as -5 + 3x^2-3. Next, we need to use the order of operations to evaluate the expression. The first step is to simplify any terms within parentheses, so we simplify 3x^2-3 to 3x^2-3 = 3x^2-3.

Now, the expression can be rewritten as -5 + 3x^2-3. The next step is to perform any multiplication or division, so we multiply 3 with x^2 to get 3x^2.

The expression is now -5 + 3x^2. The last step is to perform any addition or subtraction, so we add -5 and 3x^2 to get 3x^2-5.

Inequalities is taught in 9th grade. To solve the inequality:

-  First, simplify the expression: open the parentheses of algebraic expression, combine the terms like, and isolate the target variable.

- Use mathematic operators such as: addition, subtraction, multiplication, and division. All mathematic operations must be done on both sides. Addition and subtraction do not change the inequality. Multiplication and division with positive numbers will not change the inequality.

Multiplication and division with negative numbers will change the sign of the inequality.

Example:

Solve the inequality: 3(x + 2)  <  7x - 18

Step 1: Open the parentheses.

3(x + 2)  <  7x - 18

⇔ 3x + 6 < 7x - 18
