Answer:
Step-by-step explanation:
y+2=3(x+1)
y+2=3x+3
y+3x+5
y=mx+b
m=x-intercept
x-intercept=3
Answer:
(-1/3, 0)
Step-by-step explanation:
You want the x-intercept of the line y +2 = 3(x + 1).
X-interceptThe x-intercept is the point where the graph intersects the x-axis. The value of y is zero there. It can be found by solving the equation for x with 0 substituted for y.
0 +2 = 3(x +1) . . . . . substitute y=0 in the given equation
2/3 = x +1 . . . . . . . . divide by 3
-1/3 = x . . . . . . . . . . subtract 1
The x-intercept is x=-1/3. The point there is (-1/3, 0).

how do I find the slope
Find the product of each pair of complex conjugates
(4 + 5i)(4 – 5i)
We will see that the product of the complex conjugates is equal to 41.
Finding the product of complex numbers.
Here we want to find the product of a complex number and its conjugate:
(4 + 5i)*(4 - 5i)
Here you need to remember that:
i*i = i^2 = -1
Now if we take the product we will get:
(4 + 5i)*(4 - 5i) = 4*4 + 4*(-5i) + (5i)*4 + (5i)*(-5i)
= 16 - 20i + 20i + (-25)*(i^2)
= 16 + 25 = 41

a deck of 52 cards is shuffled thoroughly, and n cards are turned up. what is the probability that one face card turns up?
A deck of 52 cards is shuffled thoroughly, and n cards are turned up. The probability that one face card turns up is (1/4) × (n/52).
The probability of one face card turning up when n cards are turned up from a shuffled deck of 52 cards is determined by the following formula:
Probability of 1 face card = (number of face cards/number of total cards) × (n/52)
Therefore, the probability of one face card turning up when n cards are turned up is (12/52) × (n/52), or (1/4) × (n/52).
For example, if 10 cards are turned up, the probability of one face card turning up would be (1/4) × (10/52) = 0.2, or 20%.
In general, the more cards are turned up, the higher the probability that one face card turns up. This is because there is a higher chance of drawing at least one face card from the larger sample.
Therefore, The probability that one face card turns up in a shuffled deck is (1/4) × (n/52).

example x=7 is a root then ( -7 ) is a factor
If (x + 7) is a factor of f(x), then x=-7 is a root and (x-7) is also a factor.
If (x + 7) is a factor of a polynomial f(x), then we know that f(-7) = 0. This means that if we substitute -7 for x in the polynomial, the result will be 0.
Conversely, if a number a makes the polynomial f(x) equal to 0, then (x-a) is a factor of f(x) by the factor theorem.
Therefore, if (x + 7) is a factor of f(x), we can conclude that
f(-7) = 0, which means that x = -7 is a root of the polynomial.
(x - (-7)) or (x - (-7)) = (x - 7) is also a factor of the polynomial.
So, if (x + 7) is a factor of a polynomial f(x), we can conclude that x = -7 is a root of the polynomial and (x - 7) is another factor of f(x).

John and Mary had Php 384 altogether. After John gave Php 36 to Mary, Mary had 3 times as much money as John. How much money did Mary had at first?
John initially had Php 132 and Mary initially had Php 252 (384 - 132).
Let's start by setting up the equations to solve for this problem.
Let x be the amount of money John had initially.
Then, Mary had (384 - x) initially.
After John gave Php 36 to Mary, John had (x - 36) left and Mary had (384 - x + 36) = (420 - x).
We are told that Mary had three times as much money as John after this transaction, so we can write:
3(x - 36) = 420 - x
Simplifying this equation gives:
3x - 108 = 420 - x
4x = 528
x = 132
Therefore, John initially had Php 132 and Mary initially had Php 252 (384 - 132).

-4/315. Alan is hiking a 70-mile-long trail. After a few days, his distance from the trail's beginning is four times as far he is from the trail's end. What's the distance Alan still has to hike
Answer:
14 miles
Step-by-step explanation:
Length of the trail = 70 miles
Let x miles be the distance that Alan has already covered from the beginning of the trial
Then the remaining distance to the end of the trail = 70 - x miles
We are given that 4 times the remaining distance is the distance already covered
Therefore x = 4(70-x)
x = 4 · 70 - 4x
x = 280 - 4x
x + 4x = 280
5x = 280
x = 280/5
or
x = 56
So distance covered = 56 miles
The distance that Alan still has to hike = 70 - 56 = 14 miles
So, the distance Alane still has to hike is the entire length of the trail, which is: y = 70 miles.
Let's start by assigning variables to the unknowns in the problem.
Let's call the distance Alan has hiked "x" and the distance he has left to hike "y". We know that the trail is 70 miles long, so we can set up an equation:
x + y = 70
We also know that after a few days, Alan's distance from the beginning of the trail (let's call that distance "d") is four times as far as he is from the end of the trail (which is 70 - d). So we can set up another equation:
d = 4(70 - d)
Simplifying this equation, we get:
d = 280 - 4d
5d = 280
d = 56
So Alan is 56 miles from the beginning of the trail and 14 miles from the end of the trail. Now we can go back to our first equation and solve for y:
x + y = 70
x + 56 + 14 = 70
x + 70 = 70
x = 0
So Alan has not hiked any distance yet, and the distance he still has to hike is the entire length of the trail, which is:
y = 70 miles
Therefore, the distance Alan still has to hike is 70 miles.

Solve for c round your answer to the nearest tenth
Answer:
C = 7.72 ~ 7.7
Step-by-step explanation:
So when you solve this equetion you must 1st find x then c
we can find x by using cos(60)
cos(60) = x/14
x = cos(60) × 14
x = 1/2 ×14
x = 7
so after we find x we are going to solve c by using cos (25)
cos (25) = X/C = 7/c
cos(25) × C = 7
C = 7/cos (25)
C = 7.72 ~ 7.7
so the solution is 7.7

The probability of rolling a 4 on one toss of a standard six-sided die and a 6 on a second toss is:____.
The probability of rolling a 4 on the first toss of a standard six-sided die and a 6 on the second toss is 1/36 or approximately 0.0278.
Each toss of a standard six-sided die is an independent event with six possible outcomes (numbers 1 to 6). To find the probability of rolling a 4 on the first toss and a 6 on the second toss, we need to consider the probabilities of each event separately and then multiply them together.
The probability of rolling a 4 on the first toss is 1/6 since there is one favorable outcome (rolling a 4) out of six possible outcomes. Similarly, the probability of rolling a 6 on the second toss is also 1/6.
To find the probability of both events occurring, we multiply the individual probabilities together: (1/6) * (1/6) = 1/36.
Therefore, the probability of rolling a 4 on the first toss of a standard six-sided die and a 6 on the second toss is 1/36 or approximately 0.0278.

find the inverse laplace transform of 8s 2s2−25s>5
The value of the function 8s/ 2s^2−25s using inverse Laplace transform is equal to 4e^(25t/2).
Function is equal to,
8s/ 2s^2−25s
Value of 's' after factorizing the denominator we get,
2s^2−25s = 0
⇒ s( 2s -25 ) =0
⇒ s =0 or s =25/2
Now apply partial fraction decomposition we get,
8s/ 2s^2−25s = A/s + B /(2s -25)
Simplify it we get,
⇒ 8s = A(2s -25) + Bs
Now substitute s =0 we get,
⇒ 0 = A (-25) + 0
⇒ A =0
and s = 25/2
⇒8(25/2) = A(2×25/2 -25 ) + B(25/2)
⇒100 = B(25/2)
⇒B = 8
Now ,
8s/ 2s^2−25s = 0/s + 8 /(2s -25)
⇒ 8s/ 2s^2−25s = 8 /(2s -25)
Take inverse Laplace transform both the side we get,
L⁻¹ [8s / (2s^2 - 25s)] = L⁻¹ [8/(2s - 25)]
Apply , L⁻¹ [1/(as + b)] = (1/a)e^(-bt/a),
here,
a = 2 , b = -25
L⁻¹ [8s / (2s^2 - 25s)]
= L⁻¹ [8/(2s - 25)]
= (8/2) e^(25t/2)
= 4e^(25t/2)
Therefore, the value of inverse Laplace transform for the given function is equal to 4e^(25t/2)
