Answer:
Below
Step-by-step explanation:
First , write it in point (-6, -10) slope ( 6 ) form then manipulate it to standard form:
(y- -10) = 6 ( x - -6)
y+10 = 6x + 36
6x - y = -26
suppose that g(x) = f(x) -7 which statement best compares the graph of g(x) with the graph of f(x)
It implies that when F(x) shifts 7 units to the left, we get the value equal to G. (x). As a result, the graph of G(x) is the graph of F(x) with 7 units added to the left.
How is the graph of G related to the graph of f?The graph of g is the reflection of the graph of f. If g(x) = f(-x), then the graph of g is obtained from the graph of f by reflecting about the y-axis.
For instance, the result of multiplying f(x) and g(x) is h(x) = fg (x), or h(x)=f(x)g (x). if f is the function denoted by f(x) = x2 and g is the function denoted by g(x) = x + 3.
Therefore,
The Correct answer is : The two functions G(x) and F are provided to us (x).
We must determine which assertion most accurately contrasts the graphs of G(x) and F(x).
Suppose
F(x) = x [/ tex]
G(x) = x-7
When x = 1 is substituted
So, F(x) = 1
G(x) = 1-7 = -6
It implies that we obtain the value equal to the value of G when F(x) shifts 7 units to the left (x).
The graph of G(x) is therefore the graph of F(x) with 7 units added to the left.

Work out the area and the perimeter of each semicircle. Give your answer correct to two decimal places (2 d.p.).
diameter = 24mm
The area of this semi-circle is 38.28 cm² and this can be determined by using the formula of area of the semi-circle.
Given :
The diameter of the semi-circle is 10 cm.
The area of the circle is given by the formula:
A=[tex]\pi[/tex]r²
where r is the radius of the circle.
So, the area of the circle whose radius is 5cm is given by:
A=[tex]\pi[/tex]×(5)²
A=25[tex]\pi[/tex]
The area of the circle is 25[tex]\pi[/tex] then the area of the semicircle whose radius is 5cm is given by:

What are Irrational numbers?
The group of real numbers known as irrational numbers are those that cannot be written as a fraction of the form p/q, where p and q are integers. Additionally, the decimal expansion of an irrational integer is neither terminating nor recurring.
Irrational numbers are real numbers that cannot be expressed as a straightforward fraction. These cannot be stated as ratios, such as p/q, where p and q are integers, q0. It is a contradiction of rational numbers.
It has been given in question 4 < 5 < 9 and we have to show 6√5 is between 12 and 18.
For box number 1.
4 < 5 < 9 ⇒ √4 < √5 < √9
For the box number 2.
√4 < √5 < √9 ⇒ 2 < √5 < 3
For the box number 3.
we multiply the inequality by 6.
6×(2 < √5 < 3)
⇒ 6×2 < 6×√5 < 6×3
So the 6×2 < 6×√5 < 6×3
⇒ 12 < 6√5 < 18
Hence it is proven that 6√5 between 12 and 18.

Answer:
1. Acute Isosceles Triangle
2. Equiangular Equilateral Triangle
3. Obtuse Scalene Triangle
Step-by-step explanation:
Triangle 1:
It is given that there are two congruent sides. By the definition of an Isosceles Triangle, where at least two or more sides are congruent, it is an Isosceles Triangle.
An acute angle is less than 90 degrees. A right angle is 90 degrees. An obtuse angle is greater than 90 degrees. An equiangular triangle is a triangle whose angles are all of the same measure.
By these definitions, Triangle 1 is an acute Isosceles Triangle.
Triangle 2:
It is given that all three sides are congruent. By the definition of an Equilateral Triangle, where all the sides must be congruent, this is an Equilateral Triangle.
An equilateral triangle is also equiangular. So, Triangle 2 is an equiangular Equilateral Triangle.
Triangle 3:
It is given that none of the sides are congruent. By the definition of a Scalene Triangle, where none of the sides are congruent, this is a Scalene Triangle.
By the angle definitions above, as one of the angles are greater than 90 degrees, this is an obtuse triangle.
So, Triangle 3 is an obtuse Scalene Triangle.
Betsie is going to buy 250 envelopes.
Here is some information about the cost of envelopes in two shops.
Value World
Pack of 10 envelopes for £1.99
Buy 2 packs get 1 pack free
Letters2go
Pack of 25 envelopes for £3.19
Betsie wants to buy the envelopes for the best possible price.
Which shop should Betsie buy the 250 envelopes from?
You must show how you get your answer.
The shop for which Betsie should buy the 250 envelopes from, using proportions, is Value World.
What is a proportion?A proportion is a fraction of a total amount, and this fraction is used to build relations, using basic arithmetic operations such as multiplication or division, to obtain the desired measures.
In this problem, the final price is obtained as follows:
Divide the price by the number of packs to find the unit rate.Multiply the unit rate by 250.Hence the final price at Value World is given as follows:
1.99/10 = 0.119.
She will pay for 2/3 of the 250 packs, as she buys 2 and gets one free, hence:
2/3 x 250 x 0.119 = £19.83.
At Letters2go, the final price is obtained as follows:
3.19/25 x 250 = £31.90.
Due to the lower price, she should purchase her envelopes at Value World.

ANSWER:
The numbers are 2, 4 and 5
STEP-BY-STEP EXPLANATION:
let x be the smallest, y the one that follows and z the largest
we have the following equations
[tex]\begin{gathered} x+y+z=11 \\ z-1=2x \\ x+z=7 \end{gathered}[/tex]We solve the system of equations as follows
[tex]\begin{gathered} z-1=2x\rightarrow z=2x+1 \\ x+z=7\rightarrow z=7-x \\ \text{ we equate noth equations} \\ 2x+1=7-x \\ 2x+x=7-1 \\ 3x=6 \\ x=\frac{6}{3}=2 \end{gathered}[/tex]now, for z:

We know that if XY = 0 then there are two options: X = 0 or Y = 0
Then, in this case:
If ( 1 - v ) (5v +9 ) = 0 then
( 1 - v ) = 0 or (5v +9) = 0
We find v for both cases:
1 - v₁ = 0
1 = v₁
5v₂ + 9 = 0
5v₂ = -9
v₂ = -9/5
Answer: v₁ = 1, v₂ = -9/5If 9% of a number equals 3, find 36% of that number.

an airplane travels 600 miles against the wind in 5 hours, and makes the return trip with the same wind in 2 hours. find the rate of the wind.
Answer:
The speed of wind is 75 miles / hour
Step-by-step explanation:
Let's assume
speed of airplane is x miles /hour
speed of wind is y miles /hour
An airplane travels 600 miles against the wind in 4 hours
against wind means resultant speed will be less
so, speed =x-y
total distance traveled in 4 hour is
and this has to be equal to 600
Divide both sides by 4
makes the return trip with then same wind in 2 hours
with wind means resultant speed will be more
so, speed =x+y
total distance traveled in 2 hour is
and this has to be equal to 600
Divide both sides by 2
So, we get system of equations
now, we can solve it by adding both equations
now, we can solve for x
now, we can find y by plugging x into any one equation
If AC=13x-17, find x. Round your answer to the nearest tenth if necessary AB= 2x+4 BC= 19
x=3.7
1) Given that AC is the line segment made up by AB + BC We can set this equation:
AC=AB+BC
13x-17=2x+4+19 Combining like terms
13x-2x -17=2x-2x+23
11x -17=23
11x -17+17 = 23 +17
11x = 40 Dividing both sides by 11
x=3.63 Round to the nearest tenth

What is ascending order?When numbers are arranged in ascending order, they are done so from smallest to largest. Climbing down the stairs of numbers starting with their highest value is another way to think of descending. The slide is descended while moving down it. Ascending order, in which the numbers are arranged from lower value to higher value, is the opposite of descending order. A number can be arranged in ascending order by going from smallest to largest from left to right.
