Answer:
Soln:
Firstly, putting -2 as the value of x
y=4-x
or, y=4-(-2)
or, y=4+2
or,y=6
:. y=6
Now, putting 0 as the value of x
y=4-x
or, y=4-0
or, y=4
:. y=4
Again, putting 2 as the value of x
y=4-x
or, y=4-2
or, y=2
:. y=2
Lastly, putting 4 as the value of x
y=4-x
or, y=4-4
or, y=0
:. y=0
Therefore,(a)x=-2 , y=6
(b)x=0 , y=4
(c)x=2 , y=2
(d)x=4. , y=0
During which interval is the graph of the
function below only increasing?
HELLPPPPP!!!!!
Answer:
-2 < x < ఔ
Step-by-step explanation:
F’x = 3x^2 + 18x + 24
F’x = 3(x^2 +6x +8)
F’x = 3(x+4)(x+2)
One of the points of inflection will be at x = -2, and after -2 we know the equation will increase because it is positive

An equation with an unknown value is shown 13/10 + 2/100= ?/100
Answer:
132/100, or 1.32
Step-by-step explanation:
Just change 13/10 to 130/100 and add 2/100 to make it 132/100, or 1.32 :)
first step for solving this quadratic equation?
x2+2x-11=4
Answer:
subtract 4 from both sides
Step-by-step explanation:
Given
x² + 2x - 11 = 4
First step : subtract 4 from both sides
x² + 2x - 15 = 0 ← in standard form
Second step : factorise the quadratic
(x + 5)(x - 3) = 0 ← in factored form
Third step : equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 3 = 0 ⇒ x = 3
Fourth step : state the solutions
solutions are x = - 5, x = 3
Jamie deposits 400 into a savings account. The account has an interest rate of 5%, compounded quarterly. Right to function that gives you The amount of money in dollars, J(t) in t years after the initial deposit
Given:
Initial value = 400
Interest rate = 5% compounded quarterly.
To find:
The function that gives you the amount of money in dollars, J(t) in t years after the initial deposit.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest in decimals, n is the number of times interest compounded in an year and t is the number of years.
The interest rate is 5% compounded quarterly. So, r=0.05 and n=4.
Substituting [tex]P=400,\ r=0.05,\ n=4[/tex] in the above formula, we get
[tex]A=400\left(1+\dfrac{0.05}{4}\right)^{4t}[/tex]
[tex]A=400\left(1+0.0125\right)^{4t}[/tex]
[tex]A=400\left(1.0125\right)^{4t}[/tex]
The required function notation is:
[tex]J(t)=400\left(1.0125\right)^{4t}[/tex]
Therefore, the amount of money in dollars, J(t) in t years after the initial deposit is [tex]J(t)=400\left(1.0125\right)^{4t}[/tex].

Step-by-step explanation:
[tex]ln(x^2-25)=0[/tex]
[tex]e^{ln(x^2-25)}=e^0[/tex]
[tex]x^2-25=1[/tex]
[tex]x^2=26[/tex]
[tex]x=\pm\sqrt{26}[/tex]
The potential solutions of expression is,
⇒ x = ± √26
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ ln (x² - 25) = 0
Now, We can simplify the expression as;
⇒ ln (x² - 25) = 0
⇒ (x² - 25) = e⁰
⇒ (x² - 25) = 1
⇒ x² = 26
⇒ x = ± √26
Thus, The potential solutions of expression is,
⇒ x = ± √26

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2; when a = -2 which equation represents this direct variation between a and b? O b= -a O-=-a Ob-a=0 Ob(-a) = 0
Answer:
b = -a
Step-by-step explanation:
If a and b are both positions from 0, we need to write an equation that relates both positions. The problem is explaining that the position of a is opposite to the position of b.
If a = 2; b = -2. If a = 1000; b = -1000.
If a = -x; b = x. Then:
-a = x
-a = x and b = x, that means:
b = -a

Find the measure of angle 6.
Answer:
X = 19
Step-by-step explanation:
Two parallel lines cut by a transversal means the corresponding angles are congruent. Set each equation equal to each other and solve for x.
2x+78= 7x-17
Add 17 to both sides: 2x + 95= 7x
Then subtract 2x from both sides: 95= 5x
divide each side by 5, for final answer: x= 19
4(1+ 2y) = 12y. Solve for y.
Answer:
y=1
Step-by-step explanation:
4(1+2y)=12y
4*1 + 4*2y=12y
4 + 8y=12y
4=12y - 8y
4=4y
4/4=y
1=y

Answer:
y = 9[tex]\sqrt{2}[/tex] inches
Step-by-step explanation:
Since the base angles are congruent then the triangle is isosceles with both legs being equal.
Using Pythagoras' identity in the right triangle
y² = 9² + 9² = 81 + 81 = 162 ( take the square root of both sides )
y = [tex]\sqrt{162}[/tex] = [tex]\sqrt{81(2)}[/tex] = 9[tex]\sqrt{2}[/tex]

Se desean plantar 361 plantas de limón, en un terreno cuadrado, de manera que en cada fila queden a un metro de distancia. a)Cuántas filas de limones habrá? b)Sobrarían algunos arbolitos? c)cuántos?
Answer:
a) El número de filas de limones es [tex]n = \sqrt{361} = 19[/tex]. Es decir, se necesitan 19 filas de árboles.
b) No sobran árboles.
c) 0 árboles.
Step-by-step explanation:
Dado que las plantas de limón deben cubrir un terreno cuadrado, entonces se debe satisfacer que la siguiente condición:
[tex]n^{2} \le 361[/tex]
Donde [tex]n[/tex] es el número de filas de árboles de limón.
Si [tex]n < 19[/tex], entonces sobrarán árboles.
a) El número de filas de limones es [tex]n = \sqrt{361} = 19[/tex]. Es decir, se necesitan 19 filas de árboles.
b) No sobran árboles.
c) 0 árboles.
A cuboid has 3 different sized faces. The areas of 2 of the faces are 84cm2and 56cm2. The volume of the cuboid is 672cm3. Find the length, width and height of the cuboid and the area of the third face.
Answer:
Length: 12 cm
Width: 8 cm
Height; 7 cm
Step-by-step explanation:
We are told that the areas of 2 of the faces are 84cm² and 56cm².
Now, the side faces are 4 in total with 2 each having same areas.
Thus, it means they would have the same height.
Let's find the highest common factor between 84cm² and 56cm².
The highest number that can be divide each equally is 7.
Thus;
12 × 7 = 84 cm²
8 × 7 = 56 cm²
This means, the bottom part will measure 12 cm by 8 cm.
Thus, the complete measurement is;
Length: 12 cm
Width: 8 cm
Height; 7 cm
Let's check if it will give us a Volume equal to that given.
Thus;
Volume = 12 × 8 × 7 = 672 cm²
This is same as that given and so our dimensions are correct.

can you solve this? explian your reasoning. 2 6 3 9 6 18 15. What number comes next?
Answer:
The number of the sequence are 2, 3, 6, 15
The difference between 2 and 3 is 1 i.e. 30.
The difference between 3 and 6 is 3 i.e. 31.
The difference between 6 and 15 is 9 i.e. 32.
Let the next number in the given sequence be some natural number x.
Now, following the pattern, the difference between 15 and x has to be equal to 33=27.
i.e.
x−15=27⟹x=27+15=42
Hence
The next number in the sequence is 42.
