The additive inverse of the polynomial 7x-20 is -7x+20.

The given algebraic expression is 7x-20.

The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.

Here, the additive inverse of given polynomial is

-7x+20

Therefore, the additive inverse of the polynomial 7x-20 is -7x+20.

Answer:

[tex]y = 1.4[/tex]

Step-by-step explanation:

Given

[tex]y = width[/tex]

[tex]x = length[/tex]

[tex]y = 3;\ when\ x = 14[/tex]

Required

Find y when x = 30

Being an inverse variation, we have:

[tex]y\ \alpha\ \frac{1}{x}[/tex]

Convert the variation to an equation

[tex]y = \frac{k}{x}[/tex]

First, we solve for k

Make k the subject to solve for k

[tex]k = xy[/tex]

[tex]y = 3;\ when\ x = 14[/tex]

So, the value of k is:

[tex]k = 14 * 3[/tex]

[tex]k = 42[/tex]

To solve for y when x = 30

Substitute 30 for x and 42 for k in [tex]k = xy[/tex]

[tex]42 = 30 * y[/tex]

Make y the subject

[tex]y = \frac{42}{30}[/tex]

[tex]y = 1.4[/tex]

The width of the rectangle would be as follows:

[tex]1.4[/tex]  inches

Inverse proportion occurs when one value increases and the other decreases.

The width, [tex]y[/tex], of a rectangle with a fixed area varies inversely with its length, [tex]x[/tex].

So, [tex]y=\frac{k}{x}[/tex] where [tex]k[/tex] is the constant.

The width is [tex]3[/tex] inches when the length is [tex]14[/tex] inches.

So,

[tex]3=\frac{k}{14} \\k=42y=\frac{42}{x}\\Put x=30[/tex]

Therefore, [tex]y=\frac{42}{30}=1.4[/tex] inches

Thus, Width is [tex]\boldsymbol{1.4}[/tex] inches when the length is [tex]30[/tex] inches.

Answer:

The difference in average speed between two cars, one that traveled 160 kilometers in 5 hours, and the other that traveled 140 kilometers in the same time is:

2 km/h.

Step-by-step explanation:

a) Data and Calculations:

Let A = first car and B = second car

Distance traveled by first car = 160 kilometers (km)

Distance traveled by second car = 140 kilometers

Time taken by each car = 5 hours

Speed of A = 160/5 = 32 km/h

Speed of B = 150/5 = 30 km/h

Difference in speed =  2 km/h (32 - 30)

b) The average speed of a car is given by the distance traveled divided by the time taken to travel the distance.  The speed here is expressed in kilometers per hour (km/h).  It can also be expressed in meters per hour or second, etc.

Answer:

For any exponential function in which the base is less than 1, it will be an exponential decay situation.  In this problem, the base is 0.97.  The amount that the base is less than 1  ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.  

Step-by-step explanation:

The formula for exponential decay is y=a(1-r)x.  

r is the decay rate.

Answer:

Ok so the answer is sqrt of 39 but think about

Step-by-step explanation:

sqrt81 is 9 which is a whole number it is rational

sqrt16 is 4 which again is a whole number and is rational

1.9 is rational because it can be written as a fraction or ratio

but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.

The pattern as the exponent decreases is (c) divide the previous value by 5

The sequence on the table are given as:

125, 25, 5, 1, 1/5, 1/25......

From the above sequence, we have:

125/5 = 25

This means that the current value is gotten by dividing the previous by 5

Hence, the pattern as the exponent decreases is (c) divide the previous value by 5

======================================================

Explanation:

For any 45-45-90 right triangle, the hypotenuse H is always sqrt(2) times the leg L

In terms of symbols, we can say

[tex]H = L*\sqrt{2}[/tex]

We're told the hypotenuse is e, so H = e

Let's solve for L in terms of e

[tex]H = L*\sqrt{2}\\\\e = L*\sqrt{2}\\\\L*\sqrt{2} = e\\\\L = \frac{e}{\sqrt{2}}\\\\[/tex]

Now let's multiply top and bottom by [tex]\sqrt{2}[/tex] to rationalize the denominator

[tex]L = \frac{e}{\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2}*\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2*2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{4}}\\\\L = \frac{e\sqrt{2}}{2}\\\\[/tex]

If the hypotenuse is e, then the length of each leg is [tex]\frac{e\sqrt{2}}{2}[/tex]

This matches with choice C, which is one of the two answers. This allows us to rule out choices A and B, as those expressions are not equivalent to the expression for choice C.

----------------

The two legs of any right triangle form the base and height. The order doesn't matter. The base is always perpendicular to the height. In a right triangle, the two legs are always perpendicular.

The base and height are [tex]\frac{e\sqrt{2}}{2}[/tex] each.

The area of the triangle is...

[tex]\text{Area} = \frac{1}{2}*\text{base}*\text{height}\\\\\text{Area} = \frac{1}{2}*\frac{e\sqrt{2}}{2}*\frac{e\sqrt{2}}{2}\\\\\text{Area} = \frac{e\sqrt{2}*e\sqrt{2}}{2*2*2}\\\\\text{Area} = \frac{e*e\sqrt{2*2}}{2*2*2}\\\\\text{Area} = \frac{e^2\sqrt{4}}{2*2*2}\\\\\text{Area} = \frac{e^2*2}{2*2*2}\\\\\text{Area} = \frac{e^2}{2*2}\\\\\text{Area} = \frac{e^2}{4}\\\\[/tex]

This matches with choice E, which is the other answer. Choices D and F are eliminated as they are not equivalent to the expression for choice E.

The required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.

Given that,
An isosceles right triangle has a hypotenuse of length e.

In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.

Here,
Let the measure of the leg be x,
Apply Pythagoras' theorem,
e² = x ² + x²
e² = 2x²
x = √e²/2
x = e/√2
or
x = e√2/2

Now,?
area of the triangle is given as,
area = 1/2 × e/√2 ×e/√2
area = e² / 4

Thus, the required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.

Step-by-step explanation:

Answer:

108 student tickets, and 176 adult tickets  were sold

Step-by-step explanation:

Adult ticket $8  Call the number of adult tickets sold "a"

Student ticket $5  Call the number of student tickets sold "s"

Since we are talking about TWO consecutive days of sold out seats, the total number of seats sold were 2* 142 = 284

Then we create two different equations with the information given:

a + s = 284

8 * a + 5 * s = 1948

we can solve for s in the first equation as follows: s = 284 - a

and use it in the second equation

8 a + 5 (284 - a) = 1948

8 a + 1420 - 5 a = 1948

combining

3 a = 528

a = 528/3

a = 176

we find the number of student tickets using this answer in the substitution equation we used:

s - 284 - 176 = 108

Therefore 108 student tickets, and 176 adult tickets  were sold.

Answer:

I'm not sure if you're looking for an approximation or the exact amount, so I'll give you both. The drama club would need exactly 9.375 lbs of chocolate for the 75 orders, or 6.375 more lbs.
