(16, 36) is the image point .
What is image point?
The provided point P is "reflected" in the mirror, appearing on the other side of the line at a distance equal to that from it. To see this, move the point P. Conventionally known as P' (pronounced "P prime"), the point P's reflection over the line is also referred to as the point P's "image."Reflecting (-6, -4) in the line y= - x yields the point (4, 6).
Dilating (4, 6) by a factor of 4 gives the point (16, 36).

Can you help me please and explain I don’t get this. *slope*
Answer:-5/1
Step-by-step explanation:
down 5 and over 1
to get the slope, find a spot on the graph and then go 1 to the right and read how much the graph went up or down.
on 5) you see it did neither, so m=0
when the graph goes up, m is positive, when it goes down, m is negative.
so on graph 1, you have 2 dots.
you go 2 right, and 4 down. when the dots are not 1 apart (counting going right) then divide by the steps you went right.
4 divided by 2 is 2.
-> graph went down, slope for 1) is m = -2
graph 2) you go 2 right and 2 up, 2/2 = 1. you went up, so m is positive and m = 1 for this graph.
3) is undefined because it doesn't go anywhere when you go right, it's 100% vertical
4) m = -5 because you went 1 right and 5 down
5) you go 6 right between the dots and 4 down. m is negative because it went down, not up. so m = -(4/6)
A board game uses the deck of 20 cards shown to the right. Two cards are selected at a random from this deck. Calculate the probability that first card selected has a yellow bird and second cared selected has a lion both with and without replacement
The probability that first card selected has a yellow bird and second card selected has a lion both with and without replacement is 1/40 and 1/38. respectively.
What is probability?
Probability is the likelihood of an event or more than one event occurring. It is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Probability may also be described as the likelihood of an event occurring divided by the number of expected outcomes of the event. i.e.,
P(A) = f / N
Where:
P(A) = Probability of an event (event A) occurring
f = Number of ways an event can occur (frequency)
N = Total number of outcomes possible
Here deck of 20 cards are given which implies total number of possible outcomes are 20. From these 20 cards 5 cards has lions and 5 cards has birds in which 2 are yellow and 3 are red.
Now two cards are selected randomly.
We have to find the probability that first card selected has a yellow bird and second card selected has a lion both probability that first card selected has a yellow bird and second card selected has a lion both with and without replacement.
Probability with replacement:
Probability that first card selected has a yellow bird = 2/20 ---(1)
Since replacement is allowed so the probability that second card selected has a lion = 5/20---(2)
So, the probability that first card selected has a yellow bird and second card selected has a lion with replacement = (1) * (2) = 2/20 * 5/20 = 1/40.
Probability without replacement:
Probability that first card selected has a yellow bird = 2/20 ---(3)
And since replacement is not allowed, the probability that second card selected has a lion = 5/19---(4)
So, the probability that first card selected has a yellow bird and second card selected has a lion without replacement = (3) * (4) = 2/20 * 5/19 = 1/38.
Therefore, the probability with and without replacement is 1/40 and 1/38. respectively.

The simple interest on a sum of money invested 6 months at 5% per annum is $1680. Determine the amount of money invested.
Answer:
9514 1404 393
Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.

Answer:
24.359
Step-by-step explanation:
The height is opposite of the 77 so we are using sin. The length of the ladder is the hypotenuse.
sin(77°)=height/25 Set up equation sin=height/hypotenuse
25*sin(77°)=height Multiply both sides by 25
25*.96437=height

Answer:
The two points used to find the slope:
[tex]x_1,y_1[/tex]: 2,30
[tex]y_1,y_2:[/tex] 4,10
Final equation: y = -10x + 50
Step-by-step explanation:
From a fellow 8th grader <3
First, let's review the slope of a line: y = mx + b
Where m is the slope, and b the y-intercept
Let's find the slope. To do this I will select 2 points from this graph, and using the slope formula I will calculate it
Slope formula: [tex]\frac{rise}{run} =\frac{change- in- y}{change-in-x} =\frac{y^2-y^1}{x^2-x^1}[/tex]
To get the most accurate answer, I will be using the 2 points given that are directly on the line:
1 = (2, 30)
2 = (4, 10)
Slope: [tex]\frac{10-30}{4-2} =\frac{-20}{2} =-10[/tex]
m = -10
It makes sense that it is a negative, since the graph continues downwards.
Let's update our equation: y = -10x + b
We can see that the line intersects the y-axis at y = 50
Plug this into our b-value:
y = -10x + 50
Now, I would recommend using a graphing calculator (like a TI-83) or an online one (like desmos) to double check this. I have attached a screenshot of this line on desmos. From there we can see if this line matches up with the one seen on your graph.
Our answer is:
The two points used to find the slope:
[tex]x_1,y_1[/tex]: 2,30
[tex]y_1,y_2:[/tex] 4,10
Final equation: y = -10x + 50
Please let me know if this helped you, and if this was the correct answer! If it is incorrect I will do my best to revise my answer.
Answer: y intercept is (0,50) and Slope is -10.
Final equation is y= -10x+50
Step-by-step explanation:
Y-intercept is at what point the line intercepts the y-axis. It intersects at (0,50) coordinate point as you can see.
Slope is change in y divided by the change in x. When you change x by 1, y changes by -10. So it is -10/1 = -10. Slope is -10.
Since we know y intercept and slope equation is y=-10x+50
What is the slope of a line perpendicular to the line whose equation is 5x-y=-7. Fully simplify your answer.
Answer:
-1/5
Step-b-1/5y-step explanation:
The rule for a perpendicular slope of a line is -1/s
In this case, we find the slope of the line first.
5x - y = -7
-y = -5x - 7
y = 5x + 7
The slope is 5, so -1/(5) is the slope of the perpendicular line.

a) 56a – 178 = 98 – 248
b) 640 + 70 = 69y + 20
Answer:
A) 0.5
B) 10
Step-by-step explanation:
A) First, you need to Combine Like Terms on the right side of the =
98-248 = -150
Now, you need to Isolate the variable by getting rid of the -178. What you do to one side, you must do the the other.
56a-178(+178) = -150(+178)
56a = 28
Finally, you must remove that 56 on the a. Since it stands for 56 x a, you must do the same you did with the -178 except with Division.
56a/56 = 28/56
a = 0.5
B) Combine Like terms
640+70 = 710
Isolate the variable
710(-20) = 69y+20(=20)
690 = 69y
Remove the 69 with division
690/69 = 69y/69
10 = y

Ira invests $4000 into an account that earns 0.6% simple interest annually. Which statement best describes the relationship between the number of years Ira has his money invested and the balance in any year
The Amount of money that she received at the end of the read is $4024, the relationship between the number of years Ira has his money invested and the balance in any year differs by $24 which is the simple interest.
Amount invested by Ira = P = $4000
The rate of Interest (r) = 0.6 %
Time period (t) = 1 year.
The simple interest is given by,
[tex]S.I. = \frac{P*r*t}{100}[/tex]
Now, putting the values in the formula, we get:
[tex]S.I. = \frac{4000*0.6*1}{100} =24[/tex]
Hence, the simple interest will be $24
Now, the Amount/balance that she received in the year is A = P +S.I
A = P+S.I.
A = 4000 +24 = $4024
