Answers

the function is odd just substitute f(x) for f(-x) and replace all the x's with -x's then go back to the original problem and substitute f(x) for -f(x) and multiply the original problem by -1 and since f(-x) and -f(x) are equal, it is odd. if the original problem, f(x) and f(-x) were equal it would be even and if none of the three are equal it would be neither. the answer to this question is odd because f(-x) and -f(x) are equal.

Which is an equivalent form of the equation 4x-y= 14

Answers

4x - y = 14
-y = 14 - 4x
y = -14 + 4x

Answer:

y = 4x - 14 is equivalent from of y = 4x - 14.

Step-by-step explanation:

Given : 4x-y= 14

To find : Which is an equivalent form of the equation.

Solution : We have given 4x - y = 14.

We can write it in slope intercept form y = mx + b

Where, m = slope , b = y intercept.

4x - y = 14.

On subtracting both sides by 4x

- y= -4x + 14.

On dividing both sides by -1.

y = 4x - 14.

Therefore, y = 4x - 14 is equivalent from of y = 4x - 14.

Find the equation of the line perpendicular to y=−2 that passes through the point (4, −2).

Answers

The line y = -2 is a horizontal line through -2 on the y axis.

Anything perpendicular to this horizontal line will be a vertical line. All vertical lines are of the form x = k where k is some fixed value.

In this case, the answer is x = 4 because want the vertical line to go through (4,-2). In other words, we want all points on the vertical line to have x coordinate of 4.

Side Note: the slope of y = -2 is 0 while the slope of x = 4 is undefined.

What is the equation of the line in slope-intercept form?

Answers

The equation of the line that passes through the points is y=3/5x+3

ANSWER

The equation of the line in slope-intercept form is

[tex]y = \frac{3}{5} x + 3[/tex]

EXPLANATION

The slope intercept form of a line is given by
[tex]y = mx + c[/tex]
Where [tex]m[/tex]is the slope and [tex]c[/tex]
is the y-intercept.

We can read any two points from the graph and use it to determine the slope of the line.

For instance, the graph passes through the points
[tex](-5,0)[/tex]and [tex](0,3)[/tex]

The slope can be found using the formula,

[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]

This implies that,

[tex]m = \frac{ 3 - 0}{0 - - 5} [/tex]

[tex]m = \frac{ 3 - 0}{0 + 5} [/tex]

[tex]m = \frac{ 3 }{ 5} [/tex]

Also the y-intercept is

[tex](0,3)[/tex]

Therefore [tex]c = 3[/tex]

We substitute all these values in to the above equation to obtain,

[tex]y = \frac{3}{5} x + 3[/tex]

If y varies directly as x and y is 18 when x is 5 which expression can be used to find the value of y when x is 11?

Answers

y = kx where k is a constant Thats direct variation.

plug in given values:-

18 = k * 5

k = 18/5 = 3.6

so the equation of variation is y = 3.6x

when x = 11, y = 3.6 * 11 = 39.6 Answer

Answer:

The value of y is [tex]\frac{198}{5}[/tex] or 39.6.

Step-by-step explanation:

It is given that y varies directly as x and y. It means y is directly proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex] .... (1)

where, k is constant of proportionality.

It is given that y is 18 when x is 5.

Substitute y=18 and x=5 in equation (1).

[tex]18=k(5)[/tex]

Divide both sides by 5.

[tex]\frac{18}{5}=k[/tex]

The value of k is [tex]\frac{18}{5}[/tex]. So, the relation between x and y is

[tex]y=\frac{18}{5}x[/tex] .... (2)

We need to find the value of y when x=11.

[tex]y=\frac{18}{5}(11)[/tex]

[tex]y=\frac{198}{5}[/tex]

[tex]y=39.6[/tex]

Therefore the value of y is [tex]\frac{198}{5}[/tex] or 39.6.

how to find the factor of a trinomial?

Answers

I can tell you about the 'ac' method of factoring trinomials by way of an example:-

Factor 3x^2 - 4x - 15

first multiply the first number by the last That is 3 * -15 = -45

Now we need to find 2 factors of -45 which will when added give - 4 ( the coefficient of x)

-9 and = 5 look like the ones so we write

3x^2 - 9x + 5x - 15

Now factor this by grouping:-

= 3x(x - 3) + 5(x - 3)

x - 3 is common to the 2 parts so we have:-

(3x + 5)(x - 3) <-------- These are your factors

Any trinomial can be factored in this way.

Enter an inequality that can be used to represent this situation in the box, where x represents Victoria's neighbor's age.

Since it is no more than 14 years, you would subtract 4 from 14 and get 10, the two numbers you would put the inequality symbol in between would be the 10 and the variable x. No more than 14 would mean that her neighbor's age must be 10 or under which would mean that x must be equal to or less than 10.

Angle 1: 36 degrees - It is opposite to angle 4, and is therefore equal. To solve for angle 4, you have to do 90 - angle 3 (because it is a right angle and totals 90)
Angle 2: 90 degrees - It is a right angle
Angle 4: 36 degrees (explained above)
Angle 5: 90 degrees - It is a right angle. It is also an opposite angle to angle 2, and is therefore equal to it.

Since the two diagonal lines are parallel, the angles will relate to each other.

Angle 7: 126 - It will be 180 - angle 10 (because a straight line = 180)
Angle 8: 54 - It is opposite to angle 10, and is therefore equal
Angle 9: 126 - It will be 180 - angle 8 (because a straight line = 180). It is also an opposite angle 7, and is therefore equal
Angle 10: You already figured this one out! :)
Angle 11: 36 degrees - A triangle is 180, and angles 11, 5, and 8 all make up a triangle. Therefore, 180 - angle 5 - angle 8 = angle 11
Angle 12: 144 degrees - It will be 180 - angle 13 (because a straight line = 180).
Angle 13: 36 degrees - it is opposite to angle 11, and is therefore equal
Angle 14: 144 degrees - it is opposite to angle 12, and is therefore equal

The length of one base of a trapezoid is 19 less than five times the length of the other base. If the trapezoid has a height of 18 feet and an area of 477 ft squared, find the length of the longer base.

Answers

Area of a trapezoid: [(top +bottom)*height]/2
suppose the length of one base is x, then the other base is 5x-19
[(x+5x-19)*18]/2=477
[6x-19]*18=954
6x-19=53
6x=72
x=12
The longer base is 5*12-19=41

Final answer:

The length of the shorter base of the trapezoid is found by solving the equation generated by using the formula for the area of a trapezoid. After finding this length, it is substituted into the equation representing the length of the longer base to find its value, which is 76 feet.

Explanation:

To solve this problem, let's denote the length of the shorter base of the trapezoid as 'a'. According to the problem, the length of the longer base is then 5a - 19. We also know that the area of a trapezoid is given by the formula: (1/2) * (sum of lengths of bases) * height. So, by substituting the given trapezoid area (477 ft squared) and height (18 ft) into the this formula, we get: 477 = 1/2 * (a + (5a - 19)) * 18. Solving this equation will give us the value of 'a'. As calculating 'a' we find it to be 19. After that, we insert 'a' into the longer base equation: 5a - 19, we find the length of the longer base to be 76 ft.

168/8= 21

21 cycles will be needed to shred the aluminum.

Hope this helps!

Answer:

21.

Step-by-step explanation:

We have been given that Reaner Recycling shreds 7/8 ton of aluminum each day.The machines can shred 1/24 ton aluminum per cycle.

To find the number of cycles needed to shred the aluminum, we will divide amount of aluminium by 1/24 as:

[tex]\text{Number of cycles}=\frac{7}{8}\div \frac{1}{24}[/tex]

Convert into multiplication problem by flipping the 2nd fraction:

[tex]\text{Number of cycles}=\frac{7}{8}\times \frac{24}{1}[/tex]

[tex]\text{Number of cycles}=\frac{7}{1}\times \frac{3}{1}[/tex]

[tex]\text{Number of cycles}=7\times 3[/tex]

[tex]\text{Number of cycles}=21[/tex]

Therefore, 21 cycles will be needed to shred the aluminum.

angle efg and angle gfh are a linear pair, the measure of angle efg equals 4n+20, and measure of angle gfh equals 3n+13. what are the measures of angle efg and angle gfh?

Answers

A linear pair of angles are defined to equal 180 degrees. This means that you can add both expressions together and set them equal to 180 degrees. Once, you've done this, isolate the variable n in the equation and plug in the value to determine each angle.

Answer:

∠EFG=104° and ∠GFH=76°

Step-by-step explanation:

Given information:∠EFG = (4n+20)°, ∠GFH = (3n+13)° and ∠EFG and ∠GFH are a linear pair.

If two angles are a linear pair, then the sum of those angles is 180°.

It is given that ∠EFG and ∠GFH are a linear pair.

[tex]\angle EFG+\angle GFH=180^{\circ}[/tex]

Substitute the given values.

[tex](4n+20)+(3n+13)=180[/tex]

Combined like terms.

[tex](4n+3n)+(20+13)=180[/tex]

[tex]7n+33=180[/tex]

Subtract 33 from both sides.

[tex]7n+33-33=180-33[/tex]

[tex]7n=147[/tex]

Divide both sides by 7.

[tex]n=21[/tex]

The value of n is 21.

[tex]\angle EFG=4n+20=4(21)+20=104^{\circ}[/tex]

[tex]\angle GFH=3n+13=3(21)+13=76^{\circ}[/tex]

Therefore, the measure of ∠EFG and ∠GFH are 104° and 76° respectively.
