Answer:

x = 15

Step-by-step explanation:

Using Pythagorean Theorem

=> [tex]c^2 = a^2+b^2[/tex]

Where c= x, a = 12, b = 9

=> [tex]x^2 = (12)^2+(9)^2[/tex]

=> [tex]x^2 = 144+81[/tex]

=> [tex]x^2 = 225[/tex]

Taking sqrt on both sides

=> x = 15

Answer:

The third and fourth options.

Step-by-step explanation:

You simplify the inequality first...

-6x + 15 < 10 - 5x

-x < -5

x > 5

The first option is incorrect since it is less than.

The second option is basically -5x < 15; x > -3; that's incorrect.

The third option is basically -x < -5; x > 5; that is correct!

The fourth option is correct since it shows more than 5.

The fifth option is incorrect because it shows less than -5.

Answer:

11,8,5

Step-by-step explanation:

an=11-3(n-1)

Let n=1

a1 = 11 - 3(1-1)

    = 11 -0

    =11

Let n=2

a2 = 11-3(2-1)

     = 11 -3(1)

     = 8

Let n=3

a3 = 11-3(3-1)

    = 11 -3(2)

    = 11 -6

    =5

Answer:

The answer is 11,8,5

In two years, John will be two years younger than Paulś age today, or four years younger than Paul at the time.

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2[tex]\left[\begin{array}{ccc}10.5\\10\\\end{array}\right][/tex] + 5[tex]\left[\begin{array}{ccc}0\\3\\\end{array}\right][/tex] = 7t

[tex]\left[\begin{array}{ccc}21\\20\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}0\\15\\\end{array}\right][/tex] = 7t

[tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = 7t , thus

t = [tex]\frac{1}{7}[/tex][tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}3\\5\\\end{array}\right][/tex]

Hence T = (3, 5 )

Answer:

Please see the attached pictures for the full solution.

We reject x= -3 since x has to be between x=0 and x=10.5 since T lies on line BD.

We reject y= 1 since the y value has to be between 3 and 10 for T to lie on line BD.

Useful formula:

gradient=(y1-y2)/(x1-x2)

Further explanation:

1st picture, from line 12 to 13: cross multiply

line 14: expand

line 15: bring 9 over (or +9 on both sides)

line 16: ÷3 throughout

last picture: we have to show '(reject)' because whenever we introduce a square root, there must be a '±' sign.

Answer:

The answer is option B.

Answer: Slope 1/4  therefore slope of new line would be -1/4

Step-by-step explanation:

The points of the inverse of the line provided on the graph are as under:

x=2,y=5

x=0,y=-5

x=1,y=0

It means interchanging the values of x with the values of y and form a line which is known a inverse of a line.

firstly point out the points from the graph given in the question as in the graph1 below

now by interchanging the values we get the values of inverse of the line as in the graph 2

By plotting these points on the graph we get the inverse of the line which is in the graph 3

Answer:

The equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025

Step-by-step explanation:

The first bill amount for 2.75 hours of  landscaping work = $120.75

The second bill amount for 5.25 hours of  landscaping work = $160.50

No we are supposed to find the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour

So, we will us two point slope form to find the equation:

Formula : [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex](x_1,y_1)=(2.75,120.75)\\(x_2,y_2)=(5.25,160.50)[/tex]

Substitute the values in the formula

[tex]y-120.75=\frac{160.50-120.75}{5.25-2.75}(x-2.75)\\y=15.9x+77.025[/tex]

Hence  the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025

Answer:

14

Step-by-step explanation:

The son is x years old.

The father is 3 times older, so the father is 3x years old.

The father is 28 years older than the son, so

3x - x = 28

2x = 28

x = 14

The son is 14.

The age of his son is approximately 9 years 4 months.

Given that, a father is 3 times older than his son, or 28 years older.

We need to find the how old is the son.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, let the age of the son be x.

So, 3x=28

x=9.33

Therefore, the age of his son is approximately 9 years 4 months.

Answer:

I think it's A but I could be wrong

Answer: B

Step-by-step explanation:

A graph or table is a function if it passes the vertical line test. That means, each x and only 1 y. One x cannot have more than 1 y because, that means it does not pass the veritcal line test. In the vertical line test, the vertival line only passes through 1 point, not 2. Since we know that this graph does not pass the vertical in test, we can eliminate C and D. We can eliminate A because 2 y-values can be the same as lone as there have different x. B fits the description of what we see on the table. Therefore, the answer is B.

Answer:

y = -7/4x + 61/4

Step-by-step explanation:

Step 1: Write equation in slope-intercept form

-7y = 9 - 4x

y = 4/7x - 9/7

Step 2: Find slope of perpendicular line

Take the negative reciprocal of the 1st equation

m = -7/4

Step 3: Write out known variables

y = -7/4x + b

Step 4: Find b

3 = -7/4(7) + b

3 = -49/4 + b

b = 61/4

Step 4: Rewrite equation

y = -7/4x + 61/4

Answer:

x < -16/3 or x > 4

Step-by-step explanation:

This is split into two inequalities: 3x + 2 > 14 and -(3x + 2) > 14.

3x + 2 > 14

3x > 12

x > 4

-(3x + 2) > 14

3x + 2 < -14

3x < -16

x < -16/3

Answer:

[tex]x > 4[/tex]

Step-by-step explanation:

Move the constant to the right-hand and change its sign:

[tex]3x > 14 - 2[/tex]

Subtract the number:

[tex]3x > 12[/tex]

Divide both sides of the inequality by 3:

[tex]3 \div 12 = 4[/tex]

Therefore, the answer will be x > 4.

Answer:

The distance of the last ramp is 10 feet.

Step-by-step explanation:

From the options and the question, I assume that the height of the ramp is 6 feet. Pythagorean theorem states:

a² + b² = c²

where c is the hypotenuse, and a and b are the legs of the triangle. In this case:

6² + 8² = x²

√100 = x

10 ft = x
