Answer:

R___S___T

RT=RS+ST

(17y-33) =( 9y+3)+(3y+4)

17y-33 = 12y+ 7

17y - 12y = 7+33

5y= 40

y=40/5

y= 8

RS = 9y+3 = 9(8)+3= 72+3=75

ST= 3y+4 = 3(8)+4=24+4=28

RT= 17y-33= 17(8)-33= 136-33= 103 —>

Or ; RT=RS+ST =75+28= 103

Answer:

z = -3

Step-by-step explanation:

3 - 3z = 12

-3z = 12 - 3

-3z = 9

z = 9/-3

z = -9/3

z = -3

Answer:

z = -3

Step-by-step explanation:

3 - 3z = 12

=> - 3z = 12 - 3

=> - 3z = 9

=> z = 9/-3

=> z = -3

(1/(1/0.55) < (1/(1/0.65)

0.55> 0.65

Answer:

The angle in the upper right quadrilateral corner = 68 degrees because vertical angles are equal.

Angle Y = 68 (opposite quadrilateral angles are equal).

All quadrilateral angles add to 360 so:

68 + 68 + x + z = 360 = 292

angle X + Z = 292

Therefore angle x = angle z = 146

Step-by-step explanation:

Answer:

Step-by-step explanation:

angle Z = 68 degree (being alternate angles)

angle X = 68 degree (opposite angle of a parallelogram is equal)

y + z = 180 degree (sum of adjecent angles of a parallelogram is 180 degree)

y + 68 = 180

y = 180 - 68

y = 112 degree

Answer:

D

Step-by-step explanation:

They want to get from ln(x) to ln(-x)-9. A subtraction in a function results in every y value to be 9 units lower than originally, so this only leaves options C and D. Then the -x means that where x = 3 would give you ln(3) normallly, now x=-3 can only give you ln(3), meaning all x values are flipped around, which is done by reflecting in the y axis. This means answer D is correct

[tex]x_{1} =\frac{-17- \sqrt{129}}{2}, x_{2} =\frac{-17+ \sqrt{129}}{2} [/tex]

Step-by-step explanation:

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} = \frac{5}{2} [/tex]

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} = \frac{5}{2} [/tex]

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} - \frac{5}{2} = 0[/tex]

[tex] \frac{2(x + 2 {)}^{2} + 2(x + 3) \times (x - 3) - 5(x + 3) \times (x + 2) }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{2(x + 2 {)}^{2} + 2( {x}^{2} - 9) + ( - 15x - 15) \times (x + 2) }{2(x + 3) \times (x + 2)} = 0 [/tex]

[tex] \frac{2( {x}^{2} + 4x + 4) - 3 {x}^{2} - 48 - 25x}{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{2 {x}^{2} + 8x + 8 - 3 {x}^{2} - 48 - 25x }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] \frac{ - {x}^{2} - 17x - 40 }{2(x + 3) \times (x + 2)} = 0[/tex]

[tex] {x}^{2} + 17x + 40 = 0[/tex]

[tex]x = \frac{ - 17± \sqrt{ {17}^{2} - 4 \times 1 \times 40 } }{2 \times 1} [/tex]

[tex]x = \frac{ - 17± \sqrt{289 - 160} }{2} [/tex]

[tex]x = \frac{ - 17± \sqrt{129} }{2} [/tex]

Answer:

in order to find the answer, when adding decimals, you must count the numbers before the decimal points. Then, remove the decimal point and proceed as you would would adding whole numbers. Once finished, start from the side that has the first number and count up to the amount of numbers you counted before. Then, place the decimal point and simplify if needed.

Answer:

[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]

Or:

[tex]pm = qn \text{ and } pn + qm \neq 0[/tex]

Step-by-step explanation:

We are given two complex numbers:

[tex]\displaystyle m + ni \text{ and } p + qi[/tex]

Where m, n, p, and q are real numbers.

And we want to determine the relationship among m, n, p, and q such that the product of the two complex numbers will only have an imaginary part.

Find the product:

[tex]\displaystyle \begin{aligned} (m+ni)(p+qi) &= p(m+ni) + qi(m+ni) \\ &= (pm + pni) + (qmi + qni^2) \\ &= (pm + pni) + (qmi - qn) \\ &= (pm - qn) + i(pn + qm) \end{aligned}[/tex]

Therefore, for the product to have only an imaginary part, the real part must be zero and the imaginary part must not be zero. That is:

[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]

In conclusion, the relationship between m, n, p, and q is:

[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]

Or:

[tex]pm = qn \text{ and } pn + qm \neq 0[/tex]

Step-by-step explanation:

Well, the paper is being cut into strips. In other words, the paper is being divided. Therefore, we can divide 8 1/2 by

1 9/16 to find the amount of strips of paper that can be made.

[tex]8 \frac{1}{2} \div 1 \frac{9}{16} [/tex]

Change the mixed numbers to an improper fraction.

[tex] \frac{17}{2} \div \frac{25}{16} [/tex]

Next, use KCF (keep, change, flip) to divide the fraction.

[tex] \frac{17}{2} \times \frac{16}{25} = \frac{272}{50} = 5 \frac{22}{50} [/tex]

About 5 whole strips of paper in that size can be made from that one sheet of paper.

Answer:

[tex]f(x) = - 4 {x}^{2} + 9 \\ \\ f( - 3) = - 4 ({ - 3}^{2} ) + 9 \\ = -4 (9) + 9 \\ = - 36 + 9 \\ = - 27[/tex]

I hope I helped you^_^

Answer:

-27

Step-by-step explanation:

to find f(-3) we must substitute x to -3 in the f(x)=  -4x² +9

f(-3) = -4(-3)² +9

f(-3) = -4*9 +9

f(-3) = -36 +9

f(-3) = -27

Answer:11.1374847 Meter per second

Step-by-step explanation:

km / hr

/ = divide

To solve this question, we'll begin by converting 625 km to m. This can be obtained as follow:

1 km = 1000 m

Therefore,

625 km = 625 × 1000

625 km = 625000 m

Thus, 625 km is equivalent to 625000 m.

Next, we shall convert 4.33 hours to second. This can be obtained as follow as follow:

1 h = 3600 s

Therefore,

4.33 h = 4.33 × 3600

4.33 h = 15588 s

Thus, 4.33 h is equivalent to 15588 s.

Finally, we shall convert 625 km per 4.33 hours to m/s

625 km = 625000 m

4.33 h = 15588 s

625 km per 4.33 hours = 625000 m / 15588 s

Therefore, 625 km per 4.33 hours is equivalent to 40.09 m/s
