Answer:
(9, -5)
Step-by-step explanation:
If you rotate a figure 90 degrees counterclockwise, the coordinates will go from (x, y) to (-y, x).
So, let's start out with -y. The y-value of (-5, -9) is -9, and the negative value of that is -(-9) or 9. That goes first in our point: (9, x.) Now, we just keep our x-value the way it is, -5, and put that in our y-value: (9, -5). And there's our point after a 90 degree counterclockwise rotation.

Step-by-step explanation:
4(x+1)=3x+10
4x+4=3x+1
4x-3x+10-4
x=6
Answer:
Since x = 6, the equation only has one solution.
Step-by-step explanation
You have to solve the equation first.
Let's solve your equation step-by-step.
4 ( x + 1 ) = 3x + 10
Step 1: Simplify both sides of the equation.
4 ( x + 1 ) = 3x + 10
( 4 ) ( x ) + ( 4 ) ( 1 ) = 3x + 10 (Distribute)
4x + 4 = 3x + 10
Step 2: Subtract 3x from both sides.
4x + 4 − 3x = 3x + 10 − 3x
x + 4 = 10
Step 3: Subtract 4 from both sides.
x + 4 − 4 = 10 − 4
x = 6
Answer:
x = 6
If a car travels 200km in 2.5 hours, how far would it travel in 6 hours at the same rate of speed?
Answer: 480
Step-by-step explanation:
To solve this, you need to set up a proportion: 200/2.5 x/6
The 200 represents the km, and the 2.5 and 6 represent the hours. You can either solve this by multiplying 200 by 6 and setting it equal to 2.5 by x then solving for x, or you can find the rate the car travels in km in one hour. To do that, you divide 200 by 2.5 and get 80: this is your km per hour. Then you multiply that to 6 to see how far the car will go in 6 miles if it continues at the speed of 80 km per hour.
Answer:
Answer: 480 km
Step-by-step explanation:
As we know that if we keep speed or velocity constant, distance is directly proportional to time.
• In the first case:
[tex]{ \rm{d_{1} = kt _{1}}}[/tex]
d1 is 200 kmt1 is 2.5 hoursk is a constant of proportianality• Substitute the variables with their respective values to find the value of constant, k
[tex]{ \rm{200 = (k \times 2.5)}} \\ \\ { \rm{k = \frac{200}{2.5} }} \\ \\ { \underline{ \rm{ \: \: k = 80 \: km {h}^{ - 1} \: \: }}}[/tex]
• In the second case
[tex]{ \rm{d _{2} = kt _{2} }}[/tex]
d2 is what we needt2 is 6 hoursk is 80 kmh-¹[tex]{ \rm{d _{2} = (80 \times 6)}} \\ \\ { \boxed{ \boxed{ \rm{ \: \: d _{2} = 480 \: km \: \: }}}}[/tex]

Find the straight line f(x) which intersects the coordinates (8,0) and (1, -7).
Answer:
y = x - 8
Step-by-step explanation:
7/7X - 8
the y intercept was the only tricky part
Answer:
f(x)=1x-8
Step-by-step explanation:
slope: 0-(-7)/ 8-1 = 7/7= 1
eg. (1,-7)
-7= 1 -y int.
y int. = 8
therefore:
f(x) = 1x-8
is (1,4) a solution to this system of inequalities? 11x + y < 19 8x + 3y < 11

Which of the following points lies on the line perpendicular to
y = -x + 4, passing through (0,4)?
A (6,12)
B (6,0)
C (-6,-5)
D (12,-4)
E (0,1/4)
Answer:
Step-by-step explanation:
recall that perpendicular lines have slopes that are opposite reciprocals. if u don't know what opposite reciprocals are, according to study.com they are, "The term opposite reciprocals refers to two numbers that have opposite signs and are flipped fractions of each other." for example, 1/2 and -2 are opposite reciprocals.
also recall that the formula to find the slope of a line is m=y2-y1/x2-x1
to solve this problem, we need to go through all of the options and find the slope of that line using the given point and point (0,4). After that, we need to check if that slope is equal to 1. One is the opposite reciprocal of -1, and -1 is the slope of the equation y= -x+4. if the slope is equal to 1, the line will be perpendicular to the line y= -x+4.
lets do the math now:
option a)
m=y2-y1/x2-x1
m=12-4/6-0
m=8/6
m=4/3
this line isnt perpendicular to y= -x +4 cuz the slope is 4/3, which isnt equal to 1
option b)
m=y2-y1/x2-x1
m=0-4/6-0
m=-4/6
m= -2/3
this line isnt perpendicular to y= -x +4 cuz the slope is -2/3, which isnt equal to 1
--------------
ok girl i dont wanna do all the rest of the calculations. just keep doing the same thing with all the other options until you find something that has a slope of 1.

The body temperature in Fahrenheit of a sheep is modeled by the equation T=0.6sin(π28(t−9))+101.6, where t is the number of hours. To the nearest tenth of a degree, what is the temperature of the sheep when t=3? Do not include the units in your answer. NOTE: The angle is in degrees.
Answer:
101.6
Step-by-step explanation:
The temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.
Given that,
The body temperature in Fahrenheit of a sheep is modeled by the equation,
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
where t is the number of hours.
Now, substitute t=3 into the equation;
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
Since, [tex]sin(\dfrac{\pi }{28} (- 6)) = - 0.5637[/tex]
Therefore, the temperature of the sheep when t=3 is:
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
[tex]T = 0.6 \times - 0.5637 + 101.6[/tex]
[tex]T = 101.24[/tex]
So, the temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.

Step-by-step explanation:
6 Moves 5 places to the left to become the whole number.
It's negative 5 as you moved the digit from a decimal to whole number.
As it moved 5 places it's x100000.
So it's 10^5 but it's negative
A DNA sequence can be represented as a string of the letters ACTG (short for adenine, cytosine, guanine, and thymine). How many DNA sequences are exactly 29 letters long?
To solve that question we can think by the following way:
The first letter can be any of the letters (A, C, T or G). Therefore there are 4 possibilites.To choose the second letter of the sequence, any letter also can be chose. So, one more time, there are 4 possibilites.Using the fundamental principle of counting, we will find out that can be formed [tex]4\times 4 = 16[/tex] differents sequences (for example, AA, AG, TT, TG, CT...).
Know we know that, we can generalize. If I have [tex]n[/tex] elements and I must choose one of them [tex]t[/tex] times to do a sequence, the total number of sequence that I can form will be [tex]n^t[/tex].
In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is [tex]4\times 4\times 4\times ... \times 4[/tex] (29 times) [tex]= 4^{29}[/tex].
Therefore, there are [tex]4^{29}[/tex] DNA sequences with exactly 29 letters long.

Given f(x) contains the point (-5,6), find the point contained on
f-1(x).
Answer:
[tex]\displaystyle f^{-1}(6) = -5[/tex]
Step-by-step Explanation:
Recall that by the definition of inverse functions:
[tex]\displaystyle \text{If } f(a) = b\text{, then } f^{-1}(b) = a[/tex]
We are given the function f which contains the point (-5,6). In other words:
[tex]\displaystyle f(-5) = 6[/tex]
Then by the definition of inverse functions:
[tex]\displaystyle f^{-1}(6) = -5[/tex]
