Answer:
Step-by-step explanation:
y = mx + b Calculate the slope, m, from the given point values, solve for b by using one of the point values, and check your solution using the other point values.
A line can be thought of as the ratio of the change between horizontal (x) and vertical (y) positions. Thus, for any two points defined by Cartesian (planar) coordinates such as those given in this problem, you simply set up the two changes (differences) and then make the ratio to obtain the slope, m.
Vertical difference “y” = y 2 – y 1 = − 5 – 1 = − 6
Horizontal difference “x” = x 2 – x 1 = − 2 – − 3 = 1
Ratio = “rise over run”, or vertical over horizontal = ( − 6 1 ) = − 6 for the slope, m.
A line has the general form of y = mx + b, or vertical position is the product of the slope and horizontal position, x, plus the point where the line crosses (intercepts) the x-axis (the line where z is always zero.) So, once you have calculated the slope you can put any of the two points known into the equation, leaving us with only the intercept 'b' unknown.
1 = ( − 6 ) ⋅ ( − 3 ) + b ; 1 = 18 + b ; 1 – 18 = b ; − 17 = b
Thus the final equation is y = − 6 ⋅ x − 17
We then check this by substituting the other known point into the equation:
− 5 = ( − 6 ) ⋅ ( − 2 ) − 17 ; − 5 = 12 − 17 ; 5 = − 5

The hazard management process consists of a number of activities designed to reduce loss of life and destruction of property. Natural hazard management has often been conducted independently of development planning. A distinctive feature of OAS technical assistance is the integration of the two processes.

Answer:
arc VW = 66°
Step-by-step explanation:
The inscribed angle WXY is half the measure of its intercepted arc WY, so
WY = 2 × 57° = 114°
Arc YX = 180° ( semi- circle ) , then
VW = YX - WY = 180° - 114° = 66°
Answer:
66°
Step-by-step explanation:
1) m(WY)=2*57=114°;
2) m(WX)=180-m(WY)=180-114=66°

A woman has a square garden for strawberry planting.2 of the sides have fencing.The fencing is 40m in length.Find the maximum possible area.
Answer:
The maximum possible area is 1,600 m.
Step-by-step explanation:
You already have the two sides so you just multiply 40×40 and that gives you the area.
write the equation
it passes through (0,-2) and is perpendicular to the graph of y=5x+7
Step-by-step explanation:
the line passes through (0,-2) and perpendicular to the graph of y=5x+7.
solution :

C= 7.5x +25What is the dependant variable in the formula
'X' is the input while the 'C' is the output. Because the value of 'C' depends on the value of 'x', then C would be the dependent variable, and 'C' the independent variable.

Answer:
Step-by-step explanation: 10 but thanks green guy
Answer:
x = 10
Step-by-step explanation:
The triangle has 2 congruent sides and is therefore isosceles, then the 2 base angles are congruent, both 67°
The sum of the 3 angles is 180° , that is
4x + 6 + 67 + 67 = 180
4x + 140 = 180 ( subtract 140 from both sides )
4x = 40 ( divide both sides by 4 )
x = 10
translate the sentence into an inequality.
The product of w and 8 is greater than or equal to -16.
The inequality would be 8w≥-16
Answer:
8w ≥ -16
It's pretty simple.
Product means it has something to do with multiplication.
≥ This is the greater than or equal to sign.

Given the function h(x) = x2 – 7x + 6, determine the average rate of change of
the function over the interval 3 x < 7.
Step-by-step explanation:
the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
so,
(h(7) - (h(3)) / (7 - 3)
h(7) = 7² - 7×7 + 6 = 49 - 49 + 6 = 6
h(3) = 3² - 7×3 + 6 = 9 - 21 + 6 = -6
7 - 3 = 4
(6 - -6)/4 = 12/4 = 3
the average change rate in that interval is 3 (or fully 3/1).

Answer:
Step-by-step explanation:
Since B is the midpoint, AB must be equal to BC.
AB = BC
7x - 4 = 3x + 32
Isolate the variable
7x - 4 = 3x + 32
4x = 36
x = 9
Now solve for one side.
AB = 7x - 4
AB = 7(9) - 4
AB = 59
Since both sides are equal, finding AC just means multiplying one side by 2.
AC = AB * 2
AC = (59) * 2
AC = 118
You can double check by finding the other side and multiplying by 2.
BC = 3x + 32
BC = 3(9) + 32
BC = 27 + 32
BC = 59
AC = BC*2
AC = 59*2
AC = 118

Nonsense answers, or answers that's not the question I ask for will be reported.
Answer:
x = 1 , y = 4
Step-by-step explanation:
I am assuming you're looking for what x and y are? If so, then we know that
DC and AB equal each other, so
4x + y = 8
CB and AD equal each other, so
2x + y = 6
We have two equations that cannot be solved on their own, so we must solve them as a system of equations. One process to solve is elimination.
4x + y = 8
2x + y = 6
we can multiply the second equation all by -1 to make the y's cancel out and give us x. so,
4x + y = 8
-1(2x + y) = 6
4x + y = 8
-2x -y = -6
now solve them vertically. we get:
2x = 2
and so x = 1.
Now that we found x, we must find y. Using any of the two equations froom above, we can substitue our x value of 1 into it to find y. I will use the first one.
4x + y = 8
4(1) + y = 8
4 + y = 8
y = 8 - 4
y = 4
so our x is 1 and y is 4.
hope this helps! (:

[tex]\frac{3x-7y}{8}[/tex] × [tex]\frac{6}{3x-7y}[/tex] ← cancel 3x - 7y on numerator and denominator
= [tex]\frac{1}{8}[/tex] × [tex]\frac{6}{1}[/tex] = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex] → C
(7)
[tex]\frac{6x}{x^2-9}[/tex] ÷ [tex]\frac{8}{4x-12}[/tex]
Factorise the denominators of both fractions
x² - 9 = x² - 3² = (x - 3)(x + 3) ← difference of squares
4x - 12 ← factor out 4 from each term
= 4(x - 3)
Then rewrite as
[tex]\frac{6x}{(x-3)(x+3)}[/tex] ÷ [tex]\frac{8}{4(x-3)}[/tex] ← cancel 8 and 4 by 4
= [tex]\frac{6x}{(x-3)(x+3)}[/tex] ÷ [tex]\frac{2}{x-3}[/tex]
• leave first fraction, change ÷ to × , turn second fraction ' upside down'
= [tex]\frac{6x}{(x-3)(x+3)}[/tex] × [tex]\frac{x-3}{2}[/tex] ← cancel x - 3 on numerator and denominator
= [tex]\frac{6x}{x+3}[/tex] × [tex]\frac{1}{2}[/tex] ← cancel 2 and 6 on numerator and denominator
= [tex]\frac{3x}{x+3}[/tex] → B

sam buys a rare stamp for his stamp collection at an auction. he buys the stamp for 920£ the stamp increased in value by 7% in each of the first 2 years decreased in value by 4% in the third year
The value of the stamp at the end of the third year is £976.31.
How to calculate the value?From the information, Sam buys a rare stamp for his stamp collection at an auction. he buys the stamp for 920£ the stamp increased in value by 7% in each of the first 2 years.
First year value:
= 920 + (2% × 920)
= 938.4
Second year value:
= 938.4 + (2% × 938.4)
= 957.168
Third year value:
= 957.168 + (2% × 957.168)
= £976.31
