a + 0.03a =1.03aGiven segment AB with points (-4, 8) and (6,3) respectively. Find the
coordinates of point P that partitions Segment AB in the ratio 3:2. The answer should be entered in the form (x,y) with out any spaces between characters.
Answer:
The answer is "Coordinates of point P= (2,5)"
Step-by-step explanation:
We are familiar with the internal division of AB by point P, i.e. 3:2, [tex]\frac{AP}{PB}= \frac{3}{2}[/tex]
Therefore, we use the internal division formula.
Points:
[tex]\to (-4,8) \ and \ (6,3)\\\\ x_1 = -4\\y_1 = 8\\x_2= 6\\y_2 =3 \\[/tex]
Formula:
[tex]\to x = \frac{(mx_2 + nx_1)}{(m + n)}\\\to y = \frac{(my_2 + ny_1)}{(m + n)}\\\\where,\\\\\to m = 3 \\ \to n = 2[/tex]
Replacing the x coordinate representations of A and B with x, we have
[tex]x = \frac{(3 \times 6 + 2 \times (-4))}{(3 + 2)}\\\\[/tex]
[tex]= \frac{(18 - 8)}{5}\\\\ = \frac{10}{5}\\\\ = 2[/tex]
Replacing the, y coordinate representations of A and B with y, we have
[tex]y = \frac{(3 \times 3 + 2 \times 8)}{(3 + 2)}\\\\[/tex]
[tex]= \frac{( 9 +16)}{(5)}\\\\= \frac{25}{5}\\\\=5[/tex]
The coordinates of point P= (2,5).

Solve for x. Please help quick, it’s my last question for my test
Answer:
x = 9
Step-by-step explanation:
84 + (7x + 5) + (180 - (17x-1)) = 180
84 + 7x + 5 + (181 - 17x) = 180
270 + (-10x) = 180
90 = 10x
x = 9

Step-by-step explanation: I got it right
Which of the following statements best describes the value of the expression 7x + 6 when x = 5? A. The result is a fraction. B. The result is a prime number. C. The result is a composite number. D. The result is a whole number that is neither prime nor composite.
Answer: B) The result is a prime number
==================================================
Explanation:
Replace x with 5. Then use PEMDAS to simplify.
7x+6
7*5+6
35+6
41
The expression 7x+6 is equal to 41 when x = 5.
The value 41 is prime because its factors are only 1 and 41.

Answer:
Step-by-step explanation:
Since we don't know x, let's come up with our own.
Lets chose 6 for x.
Now, let's plug in 6: y = 2 * 6 - 7
Multiply: y = 12 - 7
Subtract: y = 5
So our first point is (6, 5)
Now lets choose a second x: 5
Plug it in: y = 2 * 5 - 7
Multiply: y = 10 - 7
Subtract: y = 3
So our second point is (5, 3)
Find both of these points and your answer should look like the attached image.

than the product of and the number.
Answer:
Equation: x + 2 = 7/8x - 15
Solution: x = -136
Explanation:
x + 2 = 7/8x - 15
2 + 15 = 7/8x - x
17 = 7/8x - 8/8x
17 = -1/8x
17 × -8 = x
-136 = x

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.
Answer:
First, these angles are alternate interior angles.
[tex] 10x - 5 = 9x + 1 [/tex]
[tex] x = 6 [/tex]
Step-by-step explanation:
(10x - 5)° and (9x + 1)° are alternate interior angles. Thus, they are congruent to each other.
Thus, to find x, we will set each angle equal to the other.
[tex] 10x - 5 = 9x + 1 [/tex]
Solve for x. Collect like terms
[tex] 10x - 9x = 5 + 1 [/tex]
[tex] x = 6 [/tex]

Slope is 2, and (5, 3) is on the line.
Answer:
3 = 2(5) + b
Step-by-step explanation:
Equation for a slope is y=mx+b.
Y = Y-value on the graph
M = The slope
X = X-value on the graph
B = Y-intercept
If the coordinates are ( x, y )
Then that must mean that x = 5 and y = 3 because the numbers would replace the variables in the same order
The B-value is unknown for now but you are able to find it by solving this algebraically.
3=2(5) + b
3 = 10 + b
-10 = -10 + b
-7 = b
Because the 10 and the -10 would cancel each other. Leaving you with only -10 on the other side.
I hope that this helps.
Let f(x) represent the weight of the jar when there are x marbles, where f(0)=10. Which equation correctly represents f(x) in terms of f(x−1) for all x>0?
A
f(x)=3⋅f(x−1)
B
f(x)=f(x−1)+3
C
f(x)=f(x−1)+3x
D
f(x)=f(x−1)+2x+1
Answer:
B
Step-by-step explanation:
We essentially have the sequence:
10, 13, 16, 19, 22,25...
This is an arithmetic sequence because each subsequent term differs only by a constant.
And this constant, the common difference, is +3 since each subsequent term is 3 more than the previous term.
Hence, we can write a recursive formula for our sequence.
We will first define our first term. The first term, at x=0, is 10. Hence:
[tex]f(0)=10[/tex]
Each term, x, is +3 the previous term (x-1). Therefore:
[tex]f(x)=f(x-1)+3[/tex]
Hence, our answer is B.
Answer:
B
Step-by-step explanation:
f(x)=f(x-1)+3x
