Find the point-slope equation of the line using the point (3, 5) and 3/2 slope
Use the slash key (/) to indicate a fraction.
Answer:
y-5 = 3/2(x-3)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y-5 = 3/2(x-3)
Write the absolute value equation that is represented by the graph

Step-by-step explanation:
i am smart
look at the table below. what is the constant change? ( I put 2 and was marked wrong, and the answer can't be in a fraction form).
Answer:
1/2Step-by-step explanation:
Use two points:
(4, 2) and (8, 4)The slope is:
m = (4 - 2) / (8 - 4) = 2/4 = 1/2Constant change is the slope, which is 1/2
Answer:
by taking two points
(4,2). & (12,6)
now slope
m=[tex] \frac{6- 2}{12 - 4} = \frac{4}{8}=\frac{1}{2} [/tex]=0.5
A photographer has 12 photographs and needs to select 8 of them for a gallery show. How many ways can the photographer choose the 8 photographs?
19,958,400
445
495
990
Answer:
19,958,400
Step-by-step explanation:
There are 12 ways the photographer could go in picking the first card.
After picking the first one, there will be 11 ways left for the second.
After picking the first one, there will be 10 ways left for the third, and so on...
So our answer = (12)(11)(10)(9)(8)(7)(6)(5) = 19,958,400

Samir bought 3 pounds of cement to repair the cracks in his sidewalk.
Each crack needs to be filled with 2 ounces of cement.
Answer:
The answer is 24 cracks will be filled
Step-by-step explanation:
hope it helps :3
16 ounces in a pound. convert pounds to ounces
calculate the amount of cement we have. That would be 3 x 16 = 48 ounces of cement.
The amount of cracks to be filled : 48 /2 = 24 cracks

Required
[tex]\tan A[/tex]
The tangent of an angle is:
[tex]\tan A = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan A = \frac{BC}{CA}[/tex]
This gives:
[tex]\tan A = \frac{5}{8}[/tex]
Question 6
In triangle ABC, what is the measure of angle C if A = 85°, a = 35, and c = 15?
Round the answer to the nearest hundredth.
Answer
36.45?
Step-by-step explanation:
I think you just divide 85 by 35 and multiply 15 with that answer. 85/35 = 2.43
15x2.43 = 36.45
Would the value of
{2 + ((15 – 3) - 61) = 2
change if the braces were
removed? Explain.
Answer:
{2+[(15-3)-61]}= -47
Yes, the value would change because if it did you would use the method PEMDAS but if there were brackets you would do the process in the order of the brackets

The length of a boat is 10.8 meters. Bodies buy a scale model of the boat.the scale of the model is 1:18
Answer:
Step-by-step explanation:
1/18 x 10.8 = 0.6 meters
The model of the boats' length is 0.6 meters.
A courier service charges a flat rate of $12.50 per trip plus $0.60 per mile. They charged Films & More $23.30 to deliver a package. ( a. Write the equation for this situation) (b. How many miles did the courier service have to travel? )
Answer:
y = 0.6x + 12.5
The courier service had to travel 18 miles
Step-by-step explanation:
Create an equation where y is the cost to deliver a package, and x is the number of miles traveled.
Since the service charges $0.60 per mile, the cost can be represented by $0.60x.
There is a flat rate of $12.50, so this will be added to 0.60x.
Then, set this equal to y. Using this, create an equation:
y = 0.6x + 12.5
Find how many miles the courier service had to travel by plugging in 23.30 as y, and solving for x:
y = 0.6x + 12.5
23.3 = 0.6x + 12.5
10.8 = 0.6x
18 = x
So, the courier service had to travel 18 miles.

The nth term of a number sequence is n2-3
(a) Find the 4th term of this sequence.
b) Show that 40 is not a number in this sequence.
Here's the solution,
nth term = n² - 3
So, 4th term :
=》(4)² - 3
=》16 - 3
=》13
4th term of the sequence is 13
now, let's assume that 40 is a number in the sequence, then
=》40 = n² - 3
=》40 + 3 = n²
[tex]n = \sqrt{43} [/tex]
but, the term of the sequence should be a natural number, so our assumption was wrong, hence 40, can't be a number of this sequence.

I am an even number.
The number in my ones place is
double the digit in my tens place.
What number am I?
Plz answer
Answer:
36
Step-by-step explanation:
think of multiples of 3 that have 2-digits
12, 18, 24, 30, 36 . . .
you will hit upon the one that works
Answer:
12.
12 Is a multiple of 3, and its ones place is double the digit of its tens place.
(3,6,9,12)
1(tens place) x 2(ones place) = 2
It is also an even number.
(2,4,6,8,10,12)

==============================================================
Explanation:
f(x) is equal to both x^2-2x+3 and also -6x at the same time. Set those two expressions equal to one another and solve for x.
x^2-2x+3 = -6x
x^2-2x+3+6x = 0
x^2+4x+3 = 0
(x+3)(x+1) = 0 .... see note below
x+3 = 0 or x+1 = 0
x = -3 or x = -1
Note: 3 and 1 multiply to 3, and also add to 4.
---------------------
Once we get the x values, we plug them into either equation to find the y value.
So if x = -3, then
f(x) = x^2-2x+3
f(-3) = (-3)^2-2(-3)+3
f(-3) = 9 + 6 + 3
f(-3) = 18
or we could say
f(x) = -6x
f(-3) = -6(-3)
f(-3) = 18
Both versions produce the same output when x = -3.
The second version is easier to work with.
Since x = -3 leads to y = 18, we know that (-3, 18) is one of the solutions. That explains where your teacher got (-3, 18) from.
-----------
We'll use this idea for x = -1 now
f(x) = x^2-2x+3
f(-1) = (-1)^2-2(-1)+3
f(-1) = 1 + 2 + 3
f(-1) = 6
or we could say
f(x) = -6x
f(-1) = -6(-1)
f(-1) = 6
Like before, both versions of f(x) produce the same output when the input is x = -1.
The other solution is (-1, 6)

Both sides of an equation can be multiplied by the same number without changing the solution of the equation.
Answer:
Just as you can add or subtract the same exact quantity on both sides of an equation, you can also multiply both sides of an equation by the same quantity to write an equivalent equation. Let's look at a numeric equation, to start.
