HELP PLEASE. What is true about the domain and range of the function?
O The domain is all real numbers less than or equal to
4, and the range is all real numbers such that -3 sXs
1.
O The domain is all real numbers such that -3 sxs1,
and the range is all real numbers less than or equal to
4.
O The domain is all real numbers, and the range is all
real numbers less than or equal to 4.
O The domain is all real numbers less than or equal to
4, and the range is all real numbers.
Answer:
Step-by-step explanation:
This equation is y=4-(x+1)^2, there is no restriction upon x and y has a max value of four and approaches negative infinity as x moves away from -1 in either direction. So the domain is all real numbers and the range is all real numbers less than or equal to four.
The domain and range of the quadratic function are:
Domain: Set of all real numbers.Range: y ≤ 4.How to get the domain and range?
For a function y = f(x), we define the domain as the set of the possible inputs x, and the range is the set of the possible values y.
On the graph, we can see a quadratic function.
For the domain, we usually start assuming that the domain is the set of all real numbers, and then we remove problematic points. Where a problematic point can be a zero on a denominator or something like that.
In the case of a quadratic, there are no problematic points, then the domain is the set of all real numbers.
For the range, we can see that the function has a maximum at y = 4, and then it goes down, so the range is just:
R: y ≤ 4.

The lengths of the diagonals of a rhombus are 4x and 6x. What expression gives the perimeter of the rhombus?
Answer:
Expression gives the perimeter = 4x√17
Step-by-step explanation:
∵ The diagonals of the rhombus ⊥ to each other and
bisects each other
∴ Half the longest diagonal = 8x/2 = 4x
∴ Half the shortest diagonal = 2x/2 = x
Use Pythagoras theorem to find the length of the side of the rhombus
∴ The length of the side = √[(4x)² + (x)²] = √[16x² + x²] = √(17x²)
∴ S = x√17
∵ Perimeter of the rhombus = 4 × S
∴ P = 4 × x√17 = 4x√17
Answer:
the correct answer is 4x✓13.
how do I work this out I need full answer im lost
Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm

Step-by-step explanation:
Ashley opened a lemonade stand on her street. It costs her $12.50 to buy the supplies each day, and she sells lemonade for $2.50 a cup. If she wants to make at least $200.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Ashley needs to sell? Input your answer as a whole number.
Answer:
x= 75
Step-by-step explanation:
Subtract sales - expenses
200 - 12.5 = 187.5
2.5x = 187.5
Divide by 2.5 on both sides
187.5/2.5
x = 75

Answer:
The value of S is 11.
Step-by-step explanation:
Okay, I found this answer due to that A = S to the power of 2 right? Then, A = 121 m2, so S2 is 121 square rooted, meaning what number is multiplied the same to get 121? 11. And if you multiply 11 by 11, you get 121.

Step-by-step explanation:
Answer:
A 140
Step-by-step explanation:
Mark the center of the circle as O. It's given that
∠IOJ = 70°
∠JOK = 70°
from the drawing it looks like HOI, IOJ and JOK are supplementary angles, which means that they add up to 180°
∠HOI + ∠IOJ + ∠JOK = 180°
∠HOI = 180° - ∠IOJ - ∠JOK
∠HOI = 180° - 70° - 70°
∠HOI = 40°
∠HOI and ∠KOL are cross angles, therefore ∠HOI = ∠KOL = 40°
Since ∠HOL and ∠KOL are supplementary angles
∠HOL = 180° - ∠KOL
∠HOL = 180° - 40°
∠HOL = 140°

write the following equation in slope- intercept form 6x+2y=20
Answer:
y = -3x + 10
Step-by-step explanation:
6x+2y=20
First, you want to subtract 6x from both sides.
2y=-6x+20
Now, you want to divide by 2 on both sides because you want to get y by itself.
y = -3x + 10
Answer:
Y = -3x + 10
Step-by-step explanation:
Subtract the 6x from both sides to get y by itself
You would have 2y=-6x+20
Divide everything by 2 for the correct formula format
You would have y=-3x+10

Help please
Answer:
x = 1 or -5/2
Step-by-step explanation:
-2x^2 - 3x + 5 = 0
multiply all through by -1
2x^2 + 3x - 5 = 0
....... 2x^2 × 5 = 10x^2 = +5x × -2x
(2x^2 + 5x)-(2x - 5) = 0
x(2x + 5) - 1(2x + 5) = 0
x - 1 = 0 or 2x + 5 = 0
x = 1 or 2x = - 5
x = 1 or -5/2
