Answer:
Step-by-step explanation:
You would use -6 and 7 to start your line. With the equation “y=5/6x+7", you would put a dot on 7. Then you would use the 5/6 to start making your line. With fractions, it's always rise/run. Starting from 7, you go up 5 then over(right) 6 until you run out of room on the graph. Then you do the opposite, down 5 then back(left) 6. Then you should have your first line. Then repeat that for the next equation. Start at -6, go down 4 and back three until you run out of room on the graph, then do the opposite. Go up 4 and over 3.

Which statement is true? Select all that apply.
Answers
The true statements are:
1) The relationship is proportional
2) y = -3x is equation of the line.
3) The slope is negative.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
A graph of the line is given.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
And line passes through the points (4, -12) and (6, -18).
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = -3
The slope is negative.
Then the equation of the line is,
y + 12 = -3(x -4)
y + 12 = -3x + 12
y = -3x
This equation shows the proportional relationship.
Therefore, all the required values are given above.

Find f. Write your answer as a whole number or a decimal. DO NOT ROUND
Answers
Answer:
f = 8 feet
Step-by-step explanation:
In Δ EBC
∵ DF ⊥ BE
∵ CB ⊥ BE
∴ DF // CB
∵ D is the mid-point of CE
∵ DF // CB
∴ F is the mid-point of EB
∵ DF joining the mid-points of EB and EC
∴ DF = [tex]\frac{1}{2}[/tex] CB
∵ CB = f and DF = 4 ft
∴ 4 = [tex]\frac{1}{2}[/tex] f
→ Multiply both sides by 2
∴ 8 = f
∴ The value of f is 8 ft

Answer:
ANSWER
GIVEN:
OA= 3x-1 , OC= 5x-3, OD= 6x-5 , BO = 2x+1
AO/OC = BO/OD
[The diagonals of a Trapezium divide each other proportionally]
(3x-1)/(5x-3) =( 2x+1)/(6x-5)
(3x-1) (6x-5) = (5x-3) ( 2x+1)
3x(6x-5) -1 (6x-5) = 2x(5x-3)+1(5x-3)
18x² -15x -6x +5 = 10x² -6x +5x -3
18x² -21x +5 = 10x² - x -3
18x² -10x² -21x + x +5+3 =0
8x² - 20x +8= 0
4(2x² -5x +2) = 0
2x² -5x +2 = 0
2x² -4x -x +2= 0
[By factorization]
2x(x-2) -1(x-2)= 0
(2x-1) (x-2) = 0
(2x-1) = 0 or (x-2) = 0
x = ½ or x = 2
If we put x= ½ in OD , The value of OD is negative.
Hence, the value of is x = 2.

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
The distance between two points A(x₁,y₁) B(x₂,y₂) is given by the formula as follows :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is used to find the distance between two points. It is an application of the Pythagorean theorem. Usually, the distance covered is equal to the product of speed and time. But when speed and time in not given but coordinates are given, then only we can use this formula.

Answers
Answer and explanation:
Not sure if the question is complete or valid but I will explain each option:
Let's assume the question asks which of the options would provide a negative result of -25( as no option evaluates to -255)
A. There would be a negative result here since all golfers have a negative score of -5 after 9 holes, and therefore a total score of -25 for all five golfers
B. Temperature increases by 25 degrees after 5 hours hence 5 degrees increase for every 1 hour. This would obviously give a positive result.
C. A football team gains 25 yards in the first play and loses 5 yards in the second but has a result of 5 yards gained in total. Hence there was a penalty of losing 20 yards for a loss of 5 yards= 25 yards- 20 yards= 5yards
D. Alyson withdraws $25 every week for 5 weeks, therefore she withdraws $125 in 5 weeks. This would be a negative result of -$125.

A.Multiply 4 by x.
B.Subtract x from 6.
C.Distribute 4 to (6 – x).
D.Subtract 4 from both sides.
Answers
Answer:
C
Step-by-step explanation:
Juan's first step to solve the distributive property will be to distribute 4 to (6 – x). The correct option is C.
What is distributive property?This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
Given that Juan wants to solve the equation below using the Distributive Property 4(6 – x) = 12.
The equation can be solved as:-
4(6 – x) = 12
24 - 4x = 12
4x = 36
x = 9
Hence, the value of x is 9 when the equation is solved by distribution.
