What is the sum of an even number plus an odd number? please explain in detail only please, everyone is saying its always odd, others are saying its always even, shouldn't it be both I mean jesus
Answer:
The sum of an even number plus an odd number is odd.
Step-by-step explanation:
The sum of an even number and an odd number is odd.
For example:
2+3=5
11+10=21
51+32=83
The end digit of an even number is always 0, 2, 4, 6, or 8
The end digit of an odd number is 1, 3, 5, 7, or 9.
So if we add only the end digit of an even and an odd number we can find no combination that can give end digit 0, 2, 4, 6, or 8(i.e even).
Hence, the sum of an even number plus an odd number is odd.

A store has a 25% off sale on coats. Marcy saved $18.75 on the coat she bought. What was the original price of the coat?
Answer:
$25
Step-by-step explanation:
18.75 is 75% of a value. You can easily find the answer by dividing 18.75 and 0.75.
When you have a problem like x*5=30, you divide 30/5 to get 6. Same here, x*0.75=18.75. Divide 18.75/0.75 to get the answer.

25 dollars

if this is the graph of f(x)=a^(x+h)+k, then: A. k>1
B. 0 1
Answer: B: 0 < a < 1
Step-by-step explanation:
The equation we have is:
f(x) = a^(x + h) + k.
k is the value at where we have the horizontal line. In this particular case, we can see that we have a horizontal line at y = -4, then we can conclude that:
k ≈ -4
a is the rate of growth. If a is positive and greater than 1, we would have an increasing function, for example with a = 2, k = 0 and h = 0 we have:
2^1 = 2
2^2 =4
2^3 = 8
This is an increasing function.
Now if a is greater than 0 and smaller than 1, we have a decreasing function (as seen in the graph). For example for a = 0.5, k = 0 and h = 0 we have:
0.5^1 = 0.5
0.5^2 = 0.25
0.5^3 = 0.125
This is a decreasing function.
Then the correct option is B, 0 < a < 1

Answer:
gradient = 9
Step-by-step explanation:
The gradient of the tangent at x = a is the derivative [tex]\frac{dy}{dx}[/tex]
Differentiate using the power rule on each term
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] and [tex]\frac{d}{dx}[/tex] ( constant ) = 0
y = 2x² + 5x - 3
[tex]\frac{dy}{dx}[/tex] = 2.2[tex]x^{2-1}[/tex] + 5[tex]x^{1-1}[/tex] - 0
= 4x + 5
[tex]\frac{dy}{dx}[/tex] ( x = 1 ) = 4(1) + 5 = 4 + 5 = 9 ← gradient of tangent
Does anyone know how to tell if a graph is inverse
Step-by-step explanation:
A function f(x) has an inverse, or is one-to-one, if and only if the graph y = f(x) passes the horizontal line test. A graph represents a one-to-one function if and only if it passes both the vertical and the horizontal line tests.
you can tell if the graph is inverse if f(x) passes the horizontal line test ( basically if it touches the line that goes across *horizontally* on the graph) and a graph is a one to one function if and ONLY if it touches both vertical and horizontal lines on the graph
A population of 752,000 people decreases at a rate of 1.4% each year. Let t represent the number of years and A(t) represent the amount after years, Which function models this situation?
Solution :
Initial population, P = 752,000 .
Rate of decrease, r = 1.4 % .
Now, population decrease in 1st year :
[tex]P_1 = P( 1 - 0.014 )[/tex]
Also, population decrease in 2nd year :
[tex]P_2 = P_1( 1 -0.014 )\\\\P_2 = P( 1 - 0.014)^2[/tex]
Similarly for each next x year, population will be :
[tex]P_x = P( 1-0.014)^x[/tex]
Therefore, population after x years is given by :
[tex]P_x = 752000 ( 1-0.014)^x[/tex]

slope = 4
y intercept = 0
====================================================
Explanation:
Two points on this line are (8,32) and (12,48)
Apply the slope formula to get
m = (y2-y1)/(x2-x1)
m = (48-32)/(12-8)
m = 16/4
m = 4
The slope is 4.
Use a point like (x,y) = (8,32) and the slope we found to determine the y intercept b
y = mx+b
32 = 4*8+b
32 = 32+b
32-32 = 32+b-32 ... subtract 32 from both sides
0 = b
b = 0
------------------
We found that m = 4 is the slope and b = 0 is the y intercept
We go from y = mx+b to y = 4x+0, which simplifies to y = 4x
In short: the y coordinate is 4 times that of the x coordinate.
For instance, if x = 16, then
y = 4x = 4*16 = 64
Which leads to the point (16,64)
Note: the slope of 4 means it costs 4 dollars per gallon. We can think of this as the unit rate, or rate of change.
Answer:
y = 4x
Step-by-step explanation:
The relation is proportional ⇒ y = kx , k = [tex]\frac{y}{x}[/tex]
~~~~~~~~~~
(8, 32)
(12, 48)
(16, 64)
k = 32 ÷ 8 = 4
y = 4x

Step-by-step explanation:
On a coordinate plane, the center of a circle P is at the point (2, 15) . Point M is located on the circle at (7, 3). Which equation describes circle P?
Answer: (x - 2)^2 + (y - 15)^2 = 13^2
Step-by-step explanation:
We know that the general equation for a circle is:
(x - a)^2 + (y - b)^2 = R^2
Where:
(a, b) is the center of the circle
R is the radius of the circle.
First, we know that the center of the circle is the point P, (2, 15)
Now, we also know that point M, (7, 3), is located at the circle.
Then we know that the radius of the circle will be equal to the distance between point P and point M.
Remember that the distance between two points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
Then in our case, we have:
Distance = √( (2 - 7)^2 + (15 - 3)^2) = √(25 + 144) = 13
This means that the radius of the circle is R = 13.
Now we know the radius of the circle and the center of the circle, then we can write the equation of the circle as:
(x - 2)^2 + (y - 15)^2 = 13^2
Solve each equation. Check 19. x(x - 32)=0
Answer:
x is equal to thirty-two.
Step-by-step explanation:
x(x - 32) = 0
x² - 32x = 0
x - 32 = 0
x = 32

Use the information given to write an equation in standard form.
Slope is -2, and (4, 3) is on the line.
Answer:
[tex]2x+y=11[/tex]
Step-by-step explanation:
Standard form of an equation is written as [tex]ax+by=c[/tex] for some constants [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex].
Slope-intercept form is written as [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
Plugging in all given values in the problem ([tex]m=-2[/tex], [tex]x=4[/tex], and [tex]y=3[/tex]), we can solve for [tex]b[/tex]:
[tex]3=-2(4)=b, \\b=11[/tex].
Therefore, our equation in slope-intercept form is:
[tex]y=-2x+11[/tex].
Rewriting in this in standard form, we get our answer:

A rope is tied to a tent for support as shown. Rope Support 14 TL sin What is the length of the rope?
Answer: 10ft
Step-by-step explanation:
The pole and the distance between the rope and pole make this appear as though it is a right angled triangle which means that one should be able to calculate the length of the rope by using the Pythagorean rule where:
c² = a² + b²
a = height of right angle triangle
b = length of right angle triangle
c = hypotenuse (length of rope)
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10 ft
Length of rope = 10ft

Answer:
to determine whether the equation of the line parallel or perpendicular.we have to find there slope.
Step-by-step explanation:
2x+3y=153y=15-2x
y=15/3 -2x/3
y=5-2x/3
y=-2x/3 +5
so the cooficient tell us the slope of the line so it is -2/34x+6y=-48
6y=-48-4x
y=-4x/6 -48/6
y=-4x/6 -8
so the slope of this line is -4/6now to say two lines are parallel there slope should be the same
-2/3 ≠ -4/6
to say two line are perpendicular with one another the product of there slope should be -1
-2/3 * -4/6
=8/18
