Step-by-step explanation:

(72)¹⁴³ ≡ x (mod 7)

Since 72 ≡ 2 (mod 7),

72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).

Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)

≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

The answer is A.

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>~ 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:

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:

x=-3

Step-by-step explanation:

We move all terms to the left:

7+2x/3-(5)=0

We add all the numbers together, and all the variables

2x/3+2=0

We multiply all the terms by the denominator

2x+2*3=0

We add all the numbers together, and all the variables

2x+6=0

We move all terms containing x to the left, all other terms to the right

2x=-6

x=-6/2

x=-3

Answer:

[tex]4x^2+\dfrac{7}{2}[/tex]

Step-by-step explanation:

The given expression is :

[tex]4x^2+\dfrac{6x}{4x}+2[/tex]

We need to find the equivalent expression for the above.

As, 6x/4x = 3/2

[tex]4x^2+\dfrac{6x}{4x}+2=4x^2+\dfrac{3}{2}+2\\\\=4x^2+\dfrac{7}{2}[/tex]

Hence, the equivalent expression is [tex]4x^2+\dfrac{7}{2}[/tex].

Answer:

is a mathematics problem and is so easy and square and triangle and rectangle and circle formulas

Step-by-step explanation:

√(a - r) + m = y

√(a - r) = y - m

(a - r) = (y - m)²

a = (y - m)² + r

a = y² - 2my + m² + r.

The answer is the 2nd option.

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:

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:

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.

Step-by-step explanation:

The equation for force is

F = m * a

where F is force, m is mass, and a is acceleration

30N = m * 5m/s²

m = 6 kg

F = 6kg * 8m/s² = 48 N

Answer:

Bottom left

Step-by-step explanation:

All tables follow linear pattern except the last step in the bottom left table

x increases by 1 but y increases by 3

a change from the previous 1 to 1 increase

Since the sides are different hence the value of y has no solution

Given the equation 0.5y-2 2/5=1/2y+2.4

This can be further expressed as:

Collect the like terms

0.5y - 0.5 y = 2.4 + 2.4

0y = 4.8

Since the sides are different hence the value of y has no solution

Answer:

The missing angle B:

Step-by-step explanation:

Given the angles

A = 100⁰

C = 55⁰

B = ?

We know that the sum of the angles of triangles is 180⁰.

so

A + B + C = 180⁰

100⁰ + B + 55⁰ = 180⁰

B =  180⁰ - 55⁰ - 100⁰

B =  25⁰

Therefore, the missing angle B:

m∠B = 25⁰

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
