With a slope of m = -2 and a point being (5,-2) what’s the Y-intercept?
Answer:
c = 8
Step-by-step explanation:
Given the following data;
Slope, m = -2
Points (x, y) = (5, -2)
To find the intercept, c;
Equation of a straight line is given by the formula: y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
-2 = -2(5) + c
-2 = -10 + c
c = 10 - 2
c = 8
Therefore, the y-intercept is 8.

Answer:

Step-by-step explanation:
=============================================================
Explanation:
The tickmarks tell us which sides are the same length. This in turn tells us that points N and O are midpoints of LJ and LK respectively (since midpoints cut a segment in half). We consider segment NO to be a midsegment.
Recall that midsegments are half as long as the side they are parallel to. That means segment NO is half as long as JK. This reverses to segment JK being twice as long as segment NO.
-------------
JK = 2*(NO)
2x+8 = 2*(12)
2x+8 = 24
2x+8-8 = 24-8 .... subtract 8 from both sides
2x = 16
2x/2 = 16/2 ...... divide both sides by 2
x = 8
If x = 8, then 2x+8 = 2*8+8 = 16+8 = 24. This shows that segment JK is 24 units long which is double that of midsegment NO being 12 units long. This confirms we have the correct x value.

find the missing angle measure
Answer:
x = 93°
Step-by-step explanation:
Since, sum of the interior angles of a polygon = (n - 2) × 180°
Here, n = number of sides of the polygon
For n = 6,
Sum of interior angles of the polygon = (6 - 2) × 180°
= 720°
m∠A + m∠B + m∠C + m∠D + m∠E + m∠F = 720°
145° + 167° + 60° + 134° + 121° + x° = 720°
x + 627° = 720°
x = 720° - 627°
x = 93°

Identify the graph and describe the solution set of this system
of inequalities.
y<-3x-2
y> -3x+ 8
Answer:
We have the system:
y < -3*x - 2
y > -3*x + 8
The solution set of this system will be the intersection between the solution sets of both inequalities.
First, to find each set of solutions, we need to find the line:
y = -3*x - 2
Because we have the symbol <, the solution set will be all the points below this line, and the line will be a dashed line (meaning that the points on the line are not solutions).
For the other line we have the same approach.
First we need to find the line:
y = -3*x + 8
Now because we used the symbol >, we need to shade the region above the line, and again the line must be a shaded line.
The graph of this system can be seen below.
Where we can see that there is no intersection of the two solution sets, meaning that the system of inequalities has no solutions.

Calculus: dy/dx= ?
(d^2y)/(dx^2)= ?
d^2y/dx^2= 0 at point (x,y)=?
ln(5y) = 4xy
Differentiate both sides with respect to x, taking y = y(x) :
d/dx [ln(5y)] = d/dx [4xy]
1/(5y) d/dx [5y] = 4y + 4x dy/dx
5/(5y) dy/dx = 4y + 4x dy/dx
1/y dy/dx = 4y + 4x dy/dx
(1/y - 4x) dy/dx = 4y
dy/dx = 4y / (1/y - 4x)
Since y = 0 is outside the domain (ln(0) is undefined), we can multiply the right side by y/y :
dy/dx = 4y ² / (1 - 4xy)
To compute the second derivative, differentiate both sides again:
d/dx [dy/dx] = d/dx [4y ² / (1 - 4xy)]
d²y/dx ² = ((1 - 4xy) d/dx [4y ²] - 4y ² d/dx [1 - 4xy]) / (1 - 4xy)²
d²y/dx ² = ((1 - 4xy) 8y dy/dx - 4y ² (0 - 4y - 4x dy/dx)) / (1 - 4xy)²
d²y/dx ² = ((8y - 32xy ²) dy/dx + 16y ³ + 16xy ² dy/dx) / (1 - 4xy)²
d²y/dx ² = ((8y - 16xy ²) dy/dx + 16y ³) / (1 - 4xy)²
Substitute the first derivative founder earlier:
d²y/dx ² = ((8y - 16xy ²) (4y ² / (1 - 4xy)) + 16y ³) / (1 - 4xy)²
d²y/dx ² = ((8y - 16xy ²) 4y ² + 16y ³ (1 - 4xy)) / (1 - 4xy)³
d²y/dx ² = (16y ³ (3 - 8xy)) / (1 - 4xy)³
The second derivative vanishes wherever the numerator vanishes (so long as 4xy ≠ 1) :
16y ³ (3 - 8xy) = 0
16y ³ = 0 or 3 - 8xy = 0
y = 0 or 8xy = 3
As pointed out earlier, y = 0 is outside this function's domain, so we're left with points on the curve
y = 3/(8x)
Substituting this into the original function gives
ln(5 (3/(8x))) = 4x (3/(8x))
ln(15 / (8x)) = 12/8
ln(15) - ln(8x) = 3/2
ln(8x) = ln(15) - 3/2
8x = exp(ln(15) - 3/2)
8x = 15 exp(-3/2)
x = 15/8 exp(-3/2) → y = 1/5 exp(3/2)
or approximately (0.4184, 0.8963).
(where exp(x) = e ˣ)

(1/2, -2) and the coordinates of B are (6, 1), what are the coordinates of A?
9514 1404 393
Answer:
A = (-5, -5)
Step-by-step explanation:
Solving ...
M = (A +B)/2
for A, you find ...
A = 2M -B
A = 2(1/2, -2) -(6, 1) = (1-6, -4-1)
A = (-5, -5)

The age of a father is two less than seven times the age of his son in two years the sum of their ages will be 57 if the son's present ages S years which equation models the situation
Answer:
[tex]f = 7s -2[/tex]
[tex]f + s =53[/tex]
Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means
[tex]f = 7s -2[/tex]
In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:
[tex](f+2) + (s + 2) = 57[/tex]
[tex]f + 2 + s + 2 =57[/tex]
Collect like terns
[tex]f + s =57-2-2[/tex]
[tex]f + s =53[/tex]
So, the equations are:
[tex]f = 7s -2[/tex]
[tex]f + s =53[/tex]

Step-by-step explanation:
Of the students in the college, 60% of the students reside in the hostel and 40% of the students are day scholars. Previous year result reports that 30% of all students who stay in the hostel scored A Grade and 20% of day scholars scored A grade. At the end of the year, one student is chosen at random and found that he/she has an A grade. What is the probability that the student is a hostlier?
Answer:
the probability that the student is a hostlier is 0.6923
Step-by-step explanation:
The computation of the probability that the student is a hostlier is shown below
= (0.60 × 0.30) ÷ (0.60 × 0.30) + (0.40 × 0.20)
= (0.18) ÷ (0.18 + 0.8)
= (0.18) ÷ (0.26)
= 0.6923
Hence the probability that the student is a hostlier is 0.6923

a gift box has the shape of a cube. the length of each side is 10.5 cm. what is the volume of the gift box?
Answer:
Volume = 1,157.625cm^3
Step-by-step explanation:
A cube means all sides (length, width, and height) are the same measurement. Since we are given one measurement (length = 10.5cm), all sides will be the same measurement.
Formula for volume:
Volume = length × width × height
v = l × w × h
v = 10.5cm × 10.5cm × 10.5cm
v = 110.25cm^2 × 10.5cm
v = 1,157.625cm^3
The unit will always be to the third power because the formula calls for multiplying the same unit (in this case, cm or Centimeters) three times. cm × cm × cm = cm^3
