The angles circled in red below are same side exterior. This means that the sum of them is 180 degrees. You can make a formula like so that you will solve for x...

98 + x = 180

98 - 98 + x = 180 - 98

0 + x = 82

x = 82

Another way to solve:

The angles circled in pink below are opposite side exterior. This means that they must equal each other...

82 = x

x = 82

Step-by-step explanation:

Answer:

x = -8  &  x = 3

Step-by-step explanation:

Vertical asymptote occur when denominator is 0.

So to find the x-values, we need to middle term factor the denominator. Shown below:

[tex]x^2+5x-24\\=(x+8)(x-3)\\x=3, -8[/tex]

Thus, at x = 3 and at x = -8  --  there is vertical asymptote.

Answer:

y = (-1/2)x -3

Step-by-step explanation:

We are given

y = 2x-17

which is in slope-intercept form: y = mx +b

Where m is the slope. so, m= 2

But this is perpendicular, When a line is perpendicular then the slope become -1/m so in our case the slope m will be = -1/2

Using the point(-8,1) we can find the b i.e the y intercept

We have x = -8, y =1 and m=-1/2

y = mx + b

1 = (-1/2)(-8) + b

1 = 4 + b

=> b = 1-4

b = -3

The equation of slope intercept form will be

y = mx + b

Putting value of m= -1/2 and b = -3

y = (-1/2)x -3

Answer:

2W+3  I am really sorry if that's wrong, I don't think it is though GOODLUCK

Step-by-step explanation:

Answer:

The correct answer is option A.   2w + 3

w = 5 inches

Step-by-step explanation:

It is given that, the length of a rectangle is 3 inches more than twice its width, and its area is 65 square inches.

To find the correct option

If 'w' is the width of rectangle, then length = 3 inches more than the twice the width

length   = 2w + 3

The correct answer is option A.   2w + 3

To find the width

We have area = 65 square inches

Length * Width = 65

(2w + 3) * W = 65

2w² + 3w - 65 = 0

Solving we get ,

w = 5 and -6.5

Therefore w = 5 inches

Answer: b,c,e or 2,3,5

Step-by-step explanation:

Answer:

C D and E

Step-by-step explanation:

The only one you probably can never do is B. It get's you no where. The way A is written, it is not much help to write 18 in base 2. So A and B both won't work. The common logs and the natural logs will both work

Log(4^(x + 3)) = Log(18)

(x + 3) Log(4) = log (18)

(x + 3) * 0.6021 = 1.2553

x + 3 = 1.2553/0.6021

x + 3 = 2.08496

Now all you need do is subtract 3 from both sides. The natural logs will give you the same answer.

You could take base-4 logs of both sides and it is a possible first step, but d and e are much more efficient. You have to change both sides to base 4 before you can proceed. This one is kind of iffy.  It does say possible first steps.

Answer:

C.Take the base-4 logarithm of each side.

D.Take the natural logarithm of each side.

E. Take the common logarithm of each side.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 is in this form with slope m = 3

• Parallel lines have equal slopes, hence

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (10, 1) into the partial equation

1 = 30 + c ⇒ c = 1 - 30 = - 29

y = 3x - 29 ← in slope- intercept form

Subtract y from both sides

0 = 3x - y - 29 ( add 29 to both sides )

29 = 3x - y, thus

3x - y = 29 ← in standard form → B

Answer:

2 units

Step-by-step explanation:

ok, so, the line below says HJ is (x+1) units long. therefore:

2x-16+8 = x+1

now, let's isolate the variable.

2x-x = 1+16-8

x = 9

since we now defined variable x, we can add it to the equation that determines the length of HI.

2x-16

2(9)-16

18-16

2

the length of line segment HI is 2 units

hope this helped!

HI + IJ = HJ

With this knowledge you can from an equation like so...

2x - 16 + 8 = x + 1

Now combine like terms and solve for x

2x + (- 8 + 8) = x + 1 + 8

2x = x + 9

2x - x = x - x + 9

x = 9

To find HI plug 9 in for x and simplify

2(9) - 16

18 - 16

2

The length of HI is 2!!!

Find  the cost of the chair and desk by multiplying the total amount pent by the 70%

Chair and desk = 900 x 0.70 = $60

Subtract that cost from the total spent:

900 - 630 = $270 was spent on the other three items.

Subtract the cost of the bookshelf:

270 - 50 = 220

The two tables cost 220.

For the price of one table divide that cost by 2:

220/2 = 110

One table cost $110.

The cost of each table is $110.

Given that

There are five items i.e. chair, bookshelf, 2 tables, and a desk.

The total amount incurred for these 5 items should be $900.

And, the chair + desk = 70% of total.

The cost of the bookshelf is $50.

Since 70% of total = chair + desk

That means

Chair + desk = 0.70 of $900 = $630

So the other items cost should be

= $900 - $630

= $270

And, the cost of bookshelf is $50

So, the two tables cost should be

= $270 - $50

= $220

So for one it should be

= $220 ÷ 2

= $110

Therefore we can conclude that the cost of each table is $110.

The expression can be simplified to [tex]625 \times (uv)^4.[/tex]

To rewrite the expression (-5uv)(-5uv)(-5uv)(-5uv) using the properties of exponents, you can consolidate it using the exponent rule that states when you multiply numbers with the same base, you add the exponents. In this case, the base is -5uv, and you are multiplying it four times, so the exponent is 4:

[tex](-5uv)(-5uv)(-5uv)(-5uv) = (-5uv)^4[/tex]

Now, you can simplify further by applying the rule for raising a power to a power, which states that when you raise an exponentiated term to another exponent, you multiply the exponents:

[tex](-5uv)^4 = -5^4 \times (uv)^4[/tex]

-5^4 means -5 multiplied by itself four times:

[tex]-5^4 = -5 \times -5 \times -5 \times -5 = 625[/tex]

So, the expression can be simplified to:

[tex]625 \times (uv)^4[/tex]

Answer: ≈ 1.414

Step-by-step explanation:

You can use the pythagorean theorem, a^2 + b^2 = c^2

a^2 and b^2 are the legs and c^2 is the hypotenuse.

1^2 + 1^2 = c^2

1 + 1 = c^2

2 = c^2

√ 2 = √ c^2

c = ≈ 1.414

If f(x) = 5x^3 and g(x) = x+1, find (f•g)(x).

Note: (f•g)(x) means f(x) times g(x).

(f•g)(x) = (5x^3)(x + 1)

(f•g)(x) = 5x^4 + 5x^3

The value of x is 55 ⇒ 2nd answer

Step-by-step explanation:

* Lets revise the properties of the rhombus

- It has 4 equal sides

- Every two opposite sides are parallel

- Every two opposite angles are equal

- Every two adjacent angles are supplementary (their sum is 180°)

* Now lets solve the problem

- A square divided into two rectangles

- Each rectangle contains a shaded rhombus

- The shaded rhombus has two adjacent angles their measures are

 (2x + 20)° and 50°

∵ Every two adjacent angles in the rhombus are supplementary

∵ The sum of the supplementary angles = 180°

∴ The sum of the measures of the angles (2x + 20)° and 50° is 180°

- lets put the equation and solve it to find x

∴ (2x + 20)° + 50° = 180° ⇒ add the like terms

∴ 2x + 70° = 180° ⇒ subtract 70° from both sides

∴ 2x = 110° ⇒ divide both sides by 2

∴ x = 55°

Answer:

5, 11,17,23,29

Step-by-step explanation:

To obtain the term in the sequence add the common difference to the previous term, that is

a(1) = 5

a(2) = 5 + 6 = 11

a(3) = 11 + 6 = 17

a(4) = 17 + 6 = 23

a(5) = 23 + 6 = 29

The first five terms of an arithmetic sequence starting with 5 and a common difference of 6 are 5, 11, 17, 23, and 29.

The first five terms of the arithmetic sequence with the first term 5 and a common difference of 6 can be found by successively adding the common difference to the previous term.

Third term (a3) = a2 + 6 = 11 + 6 = 17

Fifth term (a5) = a4 + 6 = 23 + 6 = 29

Therefore, the first five terms of the arithmetic sequence are 5, 11, 17, 23, and 29.

Answer:

slope rise 3 run 2 1/2

Step-by-step explanation:

if you start from the bottom and if you start from the top it's -3 and -2 1/2

Answer: The slope is 3 and the y-intercept is 3/2

Step-by-step explanation:

The slope of a linear function can be calculated as:

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

Where y2 = f(x2) and y1 = f(x1) and f(x) is the linear function.

So here we can use any two pairs of the set of data, for example, the first two.

(-1 , -3/2) and (-1/2,0)

s = (0 -(-3/2))/(-1/2 - (-1)) = (3/2)/(1/2) =(3/2)*(2/1) = 3

So the slope is equal to 3.

the y-intercept is the value of y when x = 0, in the table we can see that when x = 0. the value of y = 3/2

So the function is: y = 3*x + 3/2

and the correct option is the fourth one.

bearing in mind that the average rate of change = slope, and for that we can simply use two points off the table.

[tex]\bf \begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} -2&12\\ 0&3\\ 3&-10.5\\ 7&-28.5\\ \cline{1-2} \end{array}\qquad \qquad \begin{array}{llll} (\stackrel{x_1}{-2}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-10.5}) \\\\\\ slope \implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-10.5-12}{3-(-2)} \\\\\\ \cfrac{-10.5-12}{3+2}\implies \cfrac{-22.5}{5}\implies -\cfrac{4.5}{1}\implies -4.5 \end{array}[/tex]

The rate of change of y with respect to x for the given function with coordinates expressed in the table is; dy/dx = -9/2

The rate of change of y with respect to x for a given linear function is simply the slope expressed as;

dy/dx = (y2 - y1)/(x2 - x1)

Let us take the first 2 coordinates which are;

(-2, 12) and (0, 3)

Thus;

dy/dx = (3 - 12)/(0 - (-2))

dy/dx = -9/2

Or dy/dx = -4.5

Step-by-step explanation:

The given path is:

y = -2x+5

Comparing with the standard form of equation:

y = mx+b

So,

m = -2

We know that product of slopes of two perpendicular lines is -1

Let m1 be the slope of the perpendicular line

m*m1=-1

-2*m1 = -1

m1 = -1/-2

m1 = 1/2

So the slope of perpendicular path is 1/2.

Since the new path passes through (-2,9)

[tex]9 = \frac{1}{2}(-2) +b\\9 = -1 +b\\b = 10[/tex]

Putting the values of m and b in standard form
