Answer:
#11 is D. x = u - k
#12 is D. x = gc
Step-by-step explanation:
I plugged random integers to test this. Anyhow, just do the inverse operation.
#11:
13 = x + 8
x = 13 - 8
x = 5
Here, x = u - k is the new equation.
#12:
23 = x/9
x = 23(9)
x = 207
Here, x = gc is the new equation.

Answer:
Try C and see if it works, but read info below
Step-by-step explanation:
Refer to the equation y=a(x-h)^2+k
If a>0 then the parabola opens up and horizontally compresses (shrinks)
If 0<a<1 then the parabola opens up and horizontally stretches
If a<0 then the parabola opens down and horizontally compresses (shrinks)
h is the horizontal shift (along the x-axis)
k is the vertical shift (along the y-axis)
Given the function f(x)=3(x+1)^2-2, we can identify the values:
a=3, so the parabola opens down and horizontally compresses (shrinks) by a factor of 3
h=-1, so the horizontal shift is one unit to the left
k=-2, so the vertical shift is 2 units down
Given the above information, none of the answer choices are correct unfortunately. Your best option to pick is C.
Which function displays this end behavior?
• As xapproaches negative infinity, y approaches positive infinity.
• As xapproaches positive infinity, yapproaches negative infinity.
A.) y = (x+ 2)^3 -9
B.) y = -2x^3-1
C.) y = -3x^3 + 4
D.) y = 3(x-1)^2
The functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches -∞ are:
Option B: [tex]y = -2x^3-1[/tex]Option C: [tex]y = -3x^3 + 4[/tex]How to find the value of the function as x approaches infinity(+ve or -ve)?If limits exist, we can take limits of the function, where x tends to -∞ or ∞, and that limiting value will be the value the function will approach.
Testing all the four functions listed for x tending to -∞ or ∞:
Case A: [tex]y = (x+ 2)^3 -9[/tex]1. For x approaching -∞
[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} ((x+2)^3 - 9) = -9 + lim_{x \rightarrow -\infty} ((x+2)^3) \rightarrow - \infty[/tex]
(since cube of negative quantity is going to be negative)
Thus, function also tends to -∞. So this function doesn't satisfy first case, thus, we don't need to test other case as only that function is needed which can satisfy both the cases.
Case B: [tex]y = -2x^3-1[/tex]1. For x approaching -∞
[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow -\infty} (-2x^3) \rightarrow \infty[/tex]
(this time, negative sign was canceled by outer negative. So function approaches positive infinity as x approaches negative infinity.
2. For x approaching ∞
[tex]lim_{x \rightarrow \infty} (y) = lim_{x \rightarrow \infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow \infty} (-2x^3) \rightarrow -\infty[/tex]
So function approaches negative infinity as x approaches positive infinity
Thus, the considered function behaves as needed.
Case C: [tex]y = -3x^3 + 4[/tex]Similar to above cases, we can see that negative sign and cube power will make this function go to positive infinity as x approaches negative infinity, and as x approaches positive infinity, the function will approach negative infinity.
Remember that finite constants added or subtracted from arbitrary large quantities(positive or negative infinity) can't affect them.
Case D: [tex]y = 3(x-1)^2[/tex]Here x is in square power, no matter if x approaches +ve or -ve infinity, the square term would make it positive. So this function cannot approach negative infinity.
Thus, only Option B and C are performing as needed. Therefore, the functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches -∞ are:
Option B: [tex]y = -2x^3-1[/tex]Option C: [tex]y = -3x^3 + 4[/tex]Learn more about limiting values of a function here:

Question Help The mean finish time for a yearly amateur auto race was 185.64 minutes with a standard deviation of 0.314 minute. The winning car, driven by Sam, finished in 185.29 minutes. The previous year's race had a mean finishing time of 110.3 with a standard deviation of 0.129 minute. The winning car that year, driven by Rita, finished in 110.02 minutes. Find their respective z-scores. Who had the more convincing victory?
Answer:
Sam has the more convincing victory with a greater Zscore value
Step-by-step explanation:
Given that :
Year 1:
Mean finish time (m) = 185.64
Standard deviation (s) = 0.314
Sam's time (x1) = 185.29
Year 2:
Mean finish time (m) = 110.3
Standard deviation (s) = 0.129
Rita's time (x1) = 110.02
Zscore = (x - mean) / standard deviation
Sam's Zscore :
(185.29 - 185.64) / 0.314
= - 0.35 / 0.314
= −1.114649
= - 1.115
Rita's Zscore :
(110.02 - 110.3) / 0.129
= - 0.28 / 0.129
= −2.170542
= - 2.171
Sam has the more convincing victory with a greater Zscore value
. Beth is making gingerbread men. She uses 2 raisins for eyes and 3 raisins for buttons for each gingerbread man. She buys 4 boxes of raisins, each with 120 raisins in it. How many dozens of gingerbread men can she make
The number of gingerbreads that Beth can be made from 4 boxes of raisins is 8 dozens.
What is Proportion?Proportions are mathematical statements where two or more ratios are made to be equivalent to each other.
Number of raisins Beth uses for one gingerbread man = 2 raisins for eyes and 3 raisins for buttons.
Number of raisins used for 1 gingerbread man = 2 + 3 = 5 raisins
Beth buys 4 boxes of raisins, each with 120 raisins in it.
Total number of raisins Beth bought = 4 × 120 = 480 raisins
So, 1 gingerbread can be made from 5 raisins.
Let x be the number of gingerbreads made from 480 raisins.
Using proportion,
1 : 5 = x : 480
1 / 5 = x / 480
Applying cross multiplication,
5x = 480
x = 480 / 5
x = 96
96 gingerbreads or 96/12 = 8 dozens of gingerbread can be made.
Hence 8 dozens of gingerbreads can be made from 4 boxes of raisins.

The function f(x) varies inversely with x and f(x)=2 when x = 16.
What is f(x) when x = 4?
Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .

Who gets this correct gets the brainliest answer
Answer:
(-1,3) (0,-2) are two points that the line goes directly through. count the rise/run from the point furthest left to the one further right. you go down 5 and right 1. since you had to go down to get there, the slope is negative. slope is rise over run so in this case it's -5/1 or slope is = -5
to find the y-intercept, you find where the line crosses the y-axis. you find what y is when x is 0. in this case it's -2
slope = -5
y-intercept = -2
and if it asks for an equation of the line, you plug those given values above, into the slope intercept form which is : y=mx+b
where m is the slope
b is the y-intercept
the equation of this line is " y = -5x -2 "
