Answer:

y = (2/3)x - 4

Step-by-step explanation:

To find the equation of the line in slope-intercept form given a table of values, you will need to calculate the slope of the line and the y-intercept. The slope of a line is a measure of its steepness, and it is calculated as the rise (change in y-values) divided by the run (change in x-values) between two points on the line. The y-intercept is the point at which the line crosses the y-axis.

Given the table x: 9, 3, -3, -9 and y: 2, -2, -6, -10, you can use any two points to calculate the slope. For example, you could use the points (9, 2) and (3, -2) to calculate the slope:

slope = (y2 - y1) / (x2 - x1) = (-2 - 2) / (3 - 9) = -4 / -6 = 2/3

To find the y-intercept, you can use the slope and one of the points from the table to substitute into the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

Using the slope and the point (9, 2), you can solve for b:

y = mx + b

2 = (2/3) * 9 + b

2 = 6 + b

b = -4

Therefore, the equation of the line in slope-intercept form is y = (2/3)x - 4.

To answer the other questions, you can use this equation to determine the y-value for a given x-value or the x-value for a given y-value. You can also use the equation to graph the line on the coordinate plane.

Answer:

Therefore, the value of k is 1.

Step-by-step explanation:

Vertical angles are pairs of angles that are opposite each other and are formed by two intersecting lines. If one angle measures 160°, the other angle must measure 180° - 160° = 20°. Therefore, if the other angle measures (3k + 61)°, we can set up the equation 20 = 3k + 61. Solving for k, we get k = -41. However, since the value of k must be a positive integer, the only possible value of k is k = 1. Therefore, the value of k is 1.

Rotation

Step-by-step explanation:

The function  [tex]f(x)=mx+b[/tex] , is the equation of a line given in slope-intercept form. Where m is the slope of the line and b is the y-intercept of the line. If you were to change the value of m, while keeping the value of b the same, that would result in a rotation. If you were to change the value of b, while keeping the value of m the same, that would result in a translation (specifically a vertical translation).

The answer for the first shape would be 24cm^2.

The answer for the second shape would be 20cm^2.

The answer for the third shape would be 30cm^2. "30".

What are Shapes?

A shape in geometry can be characterized as an object's form, outline, outer border, or outer surface.

The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time.

3cm times ___ = 12cm. 4 fits in there,

therefore 6cm^2 times 4 = 24cm^2.

The answer for the first one would be 24cm^2. "24" in the blank.

The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide.

16cm divided by ___ = 8cm. 2 fits in there,

therefore 40cm^2 divided 2 = 20cm^2.

The answer for the second one would be 20cm^2. "20" in the blank.

The third shape seems to be scaling up.

From 3cm to 4.5cm.

So for this you need to multiply. 3cm times ___ = 4.5cm.

Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division.

You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there,

therefore 20cm^2 times 1.5 = 30cm^2.

The answer for the third one would be 30cm^2. "30" in the blank.

The degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

What is the quotient?

The number we obtain when we divide one number by another is the quotient. For example, in 8 ÷ 4 = 2; here, the result of the division is 2, so it is the quotient. 8 is the dividend and 4 is the divisor.

To find the quotient and remainder when dividing 8x³ +16x² + 12x+13 by 2x+2, we can use polynomial long division.

First, we divide the leading coefficient of the dividend (8x³) by the leading coefficient of the divisor (2x). This gives us a quotient of 4x². We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the first term of the remainder:

8x³ +16x² + 12x + 13

(2x+2)(4x²)

8x³ - 8x³ -8x² -8x² +12x+13

This leaves us with 12x+13 as the first term of the remainder.

Next, we bring down the next term of the dividend (16x²) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 8x. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the next term of the remainder:

12x+13

(2x+2)(8x)

12x+13 - 16x² - 16x

-4x² -4x

This leaves us with -4x² -4x as the next term of the remainder.

Finally, we bring down the last term of the dividend (12x) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 6. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the final term of the remainder:

-4x² -4x

(2x+2)(6)

-4x² -4x -12x -12

-16x² -16x

This leaves us with -16x² -16x as the final term of the remainder.

Hence, the degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

We can write the result of the division as:

(8x³ + 16x² + 12x + 13) ÷ (2x+2) = (4x² + 8x + 6) + (-16x² -16x)/(2x+2)

The population of the state is 23.1 million

The population of the state will reach 28.3 million in 13.5 years

What is population ?

Any whole group that shares at least one trait is referred to be a population. People do not make up all populations. Populations can include, but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

        1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

So 13.5 years after 2000 the population will be 28.3 million.

The value of r is 45 and the value of s is 29

From the question, we are to solve the parallelogram for the missing variables.

The missing variables are r and s

Since opposite angles of a parallelogram are equal, we can write that

(r - 10)° = (3r - 100)°

Solve for r

r - 10 = 3r - 100

-10 + 100 = 3r - r

90 = 2r

r = 90/2

r = 45

Also,

We can write that

(5s)° = (4r - 35)°

Substitute the value of r and solve for s

5s = 4(45) - 35

5s = 180 - 35

5s = 145

s = 145/5

s = 29
