Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73  are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97  and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65

ANSWER

[tex]x = 0 \: or \: x = \frac{3}{2} \: or \: x = - 3[/tex]

EXPLANATION

The given polynomial function is

[tex]f(x) =2{x}^{3} + 3 {x}^{2} - 9x[/tex]

To find the zeros, we equate the function to zero.

[tex]2{x}^{3} + 3 {x}^{2} - 9x = 0[/tex]

Factor x,

[tex]x(2 {x}^{2} + 3x - 9) = 0[/tex]

Split the middle term,

[tex]x(2 {x}^{2} + 6x - 3x - 9) = 0[/tex]

[tex]x(2x(x + 3) - 3(x + 3) = 0[/tex]

[tex]x(2x - 3)(x + 3) = 0[/tex]

[tex]x=0,2x-3=0,x+3=0[/tex]

[tex]x = 0 \: or \: x = \frac{3}{2} \: or \: x = - 3[/tex]

Answer:

x = -3, x= 0, and x = 1.5

Step-by-step explanation:

The zeros of a function f(x) refers to the x-values for which f(x) = 0.

We simply graph the function and determine the points where the graph crosses the x-axis. Thus, we shall be solving the problem graphically;

From the attachment below, the graph of f(x) crosses the x-axis at;

x = -3, x= 0, and x = 1.5

The possible values of x are -2.4,1.4,3.9

Step-by-step explanation:

F(x)=3x - 1

G(x)=x³-3x²-4x

when we will plot we are given two functions f(x) and g(x) as:

the graph of these two functions we could clearly see that the point of intersections are the possible solutions of the equation .

F(x)=G(x)

the points of the intersection of this equation is x= -2.4,1.4,3.9

Hence the solutions are  x= -2.4,1.4,3.9.

Answer:

[tex]\large\boxed{y=\dfrac{7}{2}x-18}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

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

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

[tex]3x+4x=2y-9[/tex]

[tex]7x=2y-9[/tex]             add 9 to both sides

[tex]7x+9=2y[/tex]       divide both sides by 2

[tex]\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}[/tex]

Parallel lines have the same slope. Therefore we have the equation:

[tex]y=\dfrac{7}{2}x+b[/tex]

Put the coordinates of the point (4, -4) to the equation:

[tex]-4=\dfrac{7}{2}(4)+b[/tex]

[tex]-4=7(2)+b[/tex]

[tex]-4=14+b[/tex]       subtract 14 from both sides

[tex]-18=b\to b=-18[/tex]

Finally we have the equation:

[tex]y=\dfrac{7}{2}x-18[/tex]

Answer:

[tex]w\leq 100\ pounds[/tex]

Step-by-step explanation:

Let

w------> the weight in pounds

we know that

A delivery company charges an extra fee for a package that weighs more than 100 pounds

so

For

[tex]w> 100\ pounds[/tex] -----> the company charges an extra fee

therefore

For

[tex]w\leq 100\ pounds[/tex] ----> the company not charge an extra fee

The inequality w ≤ 100 expresses the weight limit for Sonia's package. Jesse should use kilograms to weigh the box in the mailroom.

The inequality is: w ≤ 100

Since Sonia can ship packages without paying the extra fee for weights up to 100 pounds. Therefore, any package weighing 100 pounds or less would not incur the additional charge.

Jesse should use kilograms to weigh the box of books in the mailroom because it's a more appropriate metric unit considering the size and weight of the objects in the box.

Answer:127 pages of paper

Step-by-step explanation:

18 times 7

The maximum number of pages the printer can print in 7 minutes is 119 pages, assuming it prints at the upper limit of 17 pages per minute.

To find the maximum number of pages the printer can print in 7 minutes, we multiply the maximum number of pages it can print per minute by the number of minutes.

Given:

- The printer prints fewer than 18 pages per minute.

- Number of minutes: 7

Let's use the upper limit of the printer's speed, which is 17 pages per minute (since it prints fewer than 18 pages per minute).

Maximum number of pages printed in 7 minutes:

[tex]\[ \text{Pages} = \text{Pages per minute} \times \text{Minutes} \][/tex]

[tex]\[ \text{Pages} = 17 \times 7 \][/tex]

[tex]\[ \text{Pages} = 119 \][/tex]

So, the maximum number of pages the printer can print in 7 minutes is 119 pages.

You didn't provide any context so I can't answer this. BUT!!

If you're looking at two triangles, look for the side corresponding to the unknown side. If it's an equilateral (all sides same length) triangle no need to worry. It's probably a scalene, all different lengths, because math is hard. So you'll have 3 different lengthy sides, and you can probably see which ones correspond with which based on length and position. You can use angles to help you.

Now use the sides you have the value of to determine scale factor.

Divide the length of one of the sides on one triangle by the corresponding side on the other. That's your scale factor. Now multiply it by the side that corresponds to the unknown side, and that is supposed to be your length.

Answer:

A = 78.46

Step-by-step explanation:

55^2 = 50^2 + 35^2 − 2(50)(35)cos(A)

3025 = 2500 + 1225 - 3500 cos A

- 3500 Cos A = -3725 + 3025

-3500 cos A = -700

cos A =  -700/-3500

         = 0.2

A = cos^-1 0.2

A = 78.46

Answer:

A=78.46° (to 4sf)

Step-by-step explanation:

The only way to approach this problem is to solve the equation.

55²=50²+35²-2(50)(35)cos(A)

3025=2500+1225-3500cosA

3025=3725-3500cosA

Now collecting like terms together:

3025-3725=-3500cosA

-700=-3500cosA

CosA=0.2

A=78.46° (to 4sf)

Answer:

The correct answer is 5

Step-by-step explanation:

To find this, start by multiplying them in any order. For ease, we'll multiply the first and last.

-2/3 * -3 = 2

Now we take that and multiply it by the remaining term.

2 * 2 1/2 = 5

Final answer:

Multiplying −2/3 by 2 1/2 and then by −3 results in the answer 5 after converting the mixed number to an improper fraction, considering the signs during multiplication, and simplifying the result.

Explanation:

To multiply the given numbers and write the answer in simplest form, let's break down the math step by step.

Firstly, convert the mixed number 2 1/2 into an improper fraction. To do this, multiply the whole number by the denominator of the fraction and add the numerator. This gives us 2 x 2 + 1 = 5, so 2 1/2 becomes 5/2.

Now, let's look at the multiplication operation:

−2/3 × (5/2) × (−3) = ( −2 × 5 × −3 ) / ( 3 × 2 )

When multiplying, we multiply the numerators together and the denominators together, which results in:

(−2 × 5 × −3) / (3 × 2) = (+2 × 5 × 3) / 6  = 30 / 6

When considering the signs, remember that when two numbers with the same sign multiply, the result is positive (e.g., −2 × −3 = +6), and when two numbers with opposite signs multiply, the answer is negative (e.g., −3 × 2 = −6).

The final step is to simplify the fraction 30/6, which simplifies to 5, since 30 divided by 6 equals 5.

Therefore, the answer is 5.

So what they are trying to say is that they both have the same y-intercept. Easy!

Make y the subject:

5x - 2y = 3

2y = 5x - 3

y = 2.5x - 1.5

The y-intercept is -1.5.

Make y the subject:

x + y = a

y = -x + a

Therefore, a must be -1.5 !

The system of linear equations has a solution on the y-axis only when a = -3/2

We have the system of linear equations:

5x - 2y = 3

x + y = a

Now let's write both in slope-intercept form:

y = (-3/2) + (5/2)x

y = a - x

If we want the lines to intersect at the y-axis, then we will have x = 0, replacing that we get:

Answer:

27m

Step-by-step explanation:

The diagram is shown in the attachment.

The height of the hot air balloon is calculated using the tangent ratio.

The tangent ratio involves the side length that is opposite(h) to the given angle (28) and the side length adjacent to the angle.

[tex]\tan 28\degree=\frac{h}{50}[/tex]

This implies that;

[tex]h=\50tan 28\degree[/tex]

[tex]h=26.585m[/tex]

The height is 27m to the nearest meters.

Using the tangent of the angle of elevation, the height of the hot air balloon is calculated to be approximately 26.585 meters.

To find the height of the hot air balloon, we can use trigonometric principles, specifically the tangent function, which relates the angle of elevation to the opposite side (the height of the balloon in this case) and the adjacent side (the distance from you to the balloon).

The angle of elevation to the top of the balloon is given as 28 degrees and the distance from the observer to the balloon is 50 meters. Using the formula for tangent:

tan(angle) = opposite/adjacent

In this case:

tan(28 degrees) = height/50 meters

Therefore, to find the height:

height = 50 meters * tan(28 degrees)

Calculating this using a calculator:

height ≈ 50 * 0.5317

height ≈ 26.585 meters

So, the height of the balloon is approximately 26.585 meters.
