Answer:
(-9,-6)
Explanation
Answer:
(9,-6)
Step-by-step explanation:
(x,y)→(y,-x)
Negate the x then switch
(x,y)→(y,−x)
(6,9)→(9,−(6))=(9,−6)
Evaluate the following expression
H ;-)
x = -3 and y = -2
2x² - 5xy - y³ =
= 2 · (-3)² - 5 · (-3) · (-2) - (-2)³ =
= 2 · 9 - 30 - (-8) = 18 - 30 + 8 =
= -12 + 8 = -4
Answer:
[tex]2 {x}^{2} - 5xy - {y}^{3} \\ x = - 3 \\ y = - 2 \\ 2 { (- 3)}^{2} - 5 \times - 3 \times - 2 - { (- 2)}^{3} \\ 2 \times 9 + - 30 - - 8 \\ = 18 - 30 + 8 \\ = - 4 \\ thank \: you[/tex]

The measure of an angle is 87°. What is the measure of its supplementary angle?
Answer:
180-87 = 93
Step-by-step explanation:
supplementary angles add up to 180°
so (the other angle + 87)=180°
other angle =180-87=93°
Answer:
93 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Therefore, the equation for finding the supplementary angle to 87 would be:
[tex]87 + x = 180\\x=180-87\\x=93[/tex]

Determine the largest integer value of xx in the solution of the following inequality.[tex]2x-2\leq 11[/tex]
Answer:
6
Step-by-step explanation:
Add 2 to both sides, then divide both sides by 2.
[tex]2x \leq 13 \\x \leq 13/2[/tex]
x is less than or equal to 13/2, So the largest value is 13/2, or 6.5. Meaning the largest integer value is 6

Can someone pls explain what I’m supposed to do I don’t really understand
Answer:
There are only 3 differences perform
Step-by-step explanation:
I. If x is negative, y is negative then the answer is possitive
eg. x is -2, y is -3
-2 × -3 = 6
II. If x is negative, y is positive then the answer is negative
eg. x is -1, y is 2
-1 × 2 = -2
III. If x is possitive, y is possitive then the answer is positive
eg. x is 2, y is 5
2 × 5 = 10
Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.

Which is a reasonable first step that can be used to solve the equation 2(x+6) = 3(x-4) +5? O Combine like terms, 3 and 5, on the right side of the equation. O Distribute 2 to (x + 6) and 3 to (x – 4). O Distribute 2 to x on the left side of the equation and 3 to x on the right side of the equation. O Apply the subtraction property of equality to move the 6 from the left side of the equation to the right side. Save and Exit Mark this and return Next Submit
Answer:
Distribute 2 to (x + 6) and 3 to (x – 4).
Step-by-step explanation:
While solving for:
2(x+6) = 3(x-4) + 5
Firstly, we need to open the parenthesis. For this, we've to distribute 2 to (x+6) and 3 to (x-4).

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer:
5
Step-by-step explanation:
Given:
Daily pass = $77Season ski pass = $450Skis = 2077 + 20 = 97
450 + 20 = 470
Keep multiplying 97 with random numbers until it passes 470.
97 × 4 = 388
97 × 5 = 485
So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.
Hope this helped.

Step-by-step explanation:
-2, 7, 16 ..... Determine the general rule (Tn) for this sequence
Answer:
It is Tn = 9n - 11
Step-by-step explanation:
It is an arithmetic progression:
[tex]T_{n} = a + (n - 1)d[/tex]
a is the first term, a = -2
n is number of terms
d is common difference, d = 7-(-2) = 9
[tex]T_{n} = - 2 + \{ (n - 1) \times 9 \} \\ T_{n} = - 2 + 9n - 9 \\ T_{n} = - 11 + 9n \\ T_{n} = 9n - 11[/tex]
Answer:
[tex]T_{n}[/tex] = 9n - 11
Step-by-step explanation:
There is a common difference between consecutive terms, that is
7 - (- 2) = 16 - 7 = 9
This indicates the sequence is arithmetic with nth term
[tex]T_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 2 and d = 9 , then
[tex]T_{n}[/tex] = - 2 + 9(n - 1) = - 2 + 9n - 9 = 9n - 11
