Step-by-step explanation:

Given:

The graph of a downward parabola.

To find:

The domain and range of the graph.

Solution:

Domain is the set of x-values or input values and range is the set of y-values or output values.

The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.

Domain = R

Domain = (-∞,∞)

The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.

From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.

Range = All real numbers less than or equal to -4.

Range =  (-∞,-4]

Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].

Answer:

2nd option because the number next to the x is the slope (3) and the added number is your intercept (4)

Step-by-step explanation:

answer:

the secound one :)

Answer:

y=-x-3

Step-by-step explanation:

Slope intercept form is y=, and so we had to get the x to the other side. To do that you would subtract x from each side and then you get your answer.

Answer: y>~ 570-3.25x/ 7.50

y>~ -13/30x

x>~30

Step-by-step explanation:

The solution to the inequality in the graph has been shown.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
According to the question,
x + y ≤ 120
x = 120 - y,

x ≥ 30
Or
3.25x+ 7.50 ≥570

Thus, the solution to the inequality in the graph has been shown.

Answer:

We get Y=4 when X =24

Step-by-step explanation:

If Y varies directly with X,  find Y when X=24, if Y = 5  when X= 30.​

We are given If Y varies directly with X, we can write:

[tex]Y\:\alpha\: X\\Y=kX[/tex]

Where k is constant of proportionality

We need to find Y when X=24, first we need to find k, the constant of proportionality.

Now, we are given: If Y = 5  when X= 30.​

We can find value of k

[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]

So, k=1/6

Now, we will find Y when X = 24

and k=1/6

[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]

So, Y=4 when X =24.

The picture shows us that the shape is a square.

To find the area of a square you would use the formula s^2

s= 8ft

8ft^2 = 64ft^2

with area you would need to use the unit ft^2

I hope this helps!!!

Answer: DDDDDDD

Step-by-step explanation: The formula is width x height, so we can use the expression 8 x 8 assuming this is perfectly square. 8 x 8 is 64 square units

Answer:8/9 n- 12/9

Step-by-step explanation: You do distributive property.Which is 4/9 times 2 n  but you make  both 4/9 and 2 to a fraction which is 4/9 times 2/1 which gives you 8/9 .Next you do 4/9 times 3  but make to a fraction both which is 4/9 times 3/1 which gives you 12/9 .Next you take the 8/9 n and 12/9 and you subtract it .Which gives you 8/9 n- 12/9  as your expression.

Step-by-step explanation:

Let (a,b) be the coordinates of the foot of the perpendicular from the point (−1,3) to the line 3x−4y−16=0

Answer:

side of black is 7

side of green is 14

Dilation scale factor is 2

hope this helps :)

please mark branliest

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

To find the scale factor of a dilation, we first have to find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the green shape. The length on the black shape measures 7 units and the length on the green shape measures 14 units.

Now, we divide the length taken from the figure by the length taken from the original shape.

14/7=2

Therefore, the scale factor of the dilation is 2.

I hope this helps!

Answer:

the value of y = 160

Step-by-step explanation:

exterior angle=sum of two opposite interior angle

y=(180-50)+30

y=160

Answer:

y=-3x-5

Step-by-step explanation:

given equation:

3y=x-4

slope intercept form is y=mx+b

(m is the slope, b is the y intercept)

divide by 3

y=1/3x-4/3

perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

so to find the slope of the perpendicular line, use this equation:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3.

here is our equation so far:

y=-3x+b

now, we need to find b.

Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b

1=-3(-2)+b

multiply

1=6+b

subtract 6

-5=b

so the line is y=-3x-5

Answer:

Perimeter of the rectangle =  32 cm

Step-by-step explanation:

Explanation:-

Let the height of the rectangle = 'x' cm

Thus the length of the rectangle = x + 4 cm

Perimeter of the rectangle = 2 ( length + height )

Area of the rectangle = length X height

Given area of the rectangle = 60 cm²

( length X height ) = 60

( x + 4) x  =60

 x² + 4 x - 60 =0

 x² + 10 x- 6 x - 60 =0

x ( x+10) - 6 ( x + 10 ) =0

(x+10) ( x -6 ) = 0

x = -10  and x =6

we can choose x =6

The height of the rectangle(H) = 'x' = 6 cm

The length of the rectangle (L)= 6 + 4 = 10cm

Perimeter of the rectangle = 2 ( length + height )

                                           = 2 ( 10 + 6 )

                                          = 32 cm

∴ Perimeter of the rectangle = 32 cm

Answer:

32 cm

Step-by-step explanation:

height = x

length = x+4

x(x+4)=60

x^2 +4x=60

make it into quadratic formula

x^2 + 4x - 60 =0

a=1

b=-4

c=-60

4^2-4*1*(-66)

discriminant equals to 256

square root of 256 equals to 16

x=-4+16/2 = 6

x=-4-16/2 = -10

we will use 6

length is x+4 so 6+4 = 10

width is x = 6

10 plus 10 = 20

6 plus 6= 12

20+12=32 cm

the answer is 28

hope this helps :)

Answer:

subtraction, n - 13 is 29, subtract, different numbers, 42.

Answer:

The number is 42

Step-by-step explanation:

Let the number be [tex]x[/tex]

According to the problem,

   [tex]x - 13 = 29[/tex]

⇒ [tex]x = 29 + 13[/tex]

⇒ [tex]x = 42[/tex]

Hence, the number is 42.
