Considering the definition of parallel line, the statement "They are parallel" describes the graph of y= -x+3 and y=-x+6.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where:
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Parallel lineParallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.
Two lines are parallel if they have the same slope or value of m and different y-intercepts or value of b.
This caseIn this case, you know:
y= -x+3 has a slope of -1 and an ordinate to the origin of 3.y=-x+6 has a slope of -1 and an ordinate to the origin of 6.Two lines are parallel if they have the same slope and different y-intercepts. Then, both lines are parallel.

Determine the total surface area of the composite shape below
Answer:
118.558 cm^2
Step-by-step explanation:
Ok, a rectangular cube and a Cylinder.
Let's start with the rectangular cube.
SA= 2(lw + lh + wh)
total surface area = 94 cm^2
Now the Surface Area of the of the Cone.
A=2πrh+2πr^2
A=2πrh+2πr^2=2·π·1·5+2·π·1^2≈37.69911 cm^2
Since the cone is standing on top of the rectangular cube, we need to deduct just the area of the circle.
A=πr2=π·12≈3.14159 cm^2
So, 84 cm^2 + 37.69911 cm^2 - 3.14159 cm^2
Sum the quantities:
84 cm^2 + 37.6991 cm^2 - 3.14159 cm^2
Sum the numbers 84 + 37.7 - 3.142 = 118.558:
Answer: 118.558 cm^2
Use the four-step procedure for solving the following variation problem
The height that a ball bounces varies directly as the height from which it was dropped. A tennis ball dropped from 14 inches bounces 8.4 inches. From what height was the tennis ball dropped if it bounces
42 inches?
The tennis ball needs to be dropped from the height of
(Type an integer or a decimal)
so that it bounces 42 inches.
9
Height was the tennis ball dropped if it bounces 42 inches is 0.7 inch.
What do you understand by direct proportionality?
If two quantities are directly proportional, it means that when one quantity increases at a certain rate, the other quantity also increases at the same rate up to a constant value. It is represented by the proportional symbol ∝.
Let the height of the ball bounces be h
The height of the ball drobbed from be y
It is given that the height that a ball bounces varies directly as the height from which it was dropped.
⇒ h ∝ y
⇒ h = ky where k is the constant of proportionality.
It is given that a tennis ball dropped from 14 inches.
⇒ y = 14 inches
Tennis ball bounces back to 8.4 inches.
⇒ h = 8.4 inches
⇒ 8.4 = k × 14
⇒ k = 8.4/14 = 0.6
Now, tennis ball dropped from 42 inches
y = 42
⇒ h = 42 × 0.6 = 0.7
Therefore, height was the tennis ball dropped if it bounces
42 inches is 0.7 inch.

Andrea is buying some new shirts and sweaters. She is able to buy 5 shirts and 3
sweaters for $89 or she is able to buy 9 shirts and 8 sweaters for $207. How much
does a shirt cost? How much does a sweater cost?
Answer: Shirt = $7 and Sweater = $18
Step-by-step explanation:
5 Shirts, 3 sweaters = $89 (1)
9 Shirts, 8 sweaters = $207 (2)
1 Shirt = $?
1 Sweater = $?
Shirts = x
sweaters = y
(1) -> 5x + 3y = 89
(2) -> 9x + 8y = 207
(1) * 8 = 40x + 24y = $712
(2) * 3 = 27x + 24y = $621
(1) single out 24y -> 24y = $712 - 40x
put value of 24 y into (2)
(2) -> 27x + $712 - 40x = $621
Now solve
-13x = $-91
remove negative -> 13x = $91
x = $7
So a shirt is $7
And we can put $7 into (1) at the start -> 5(7) + 3(y) = $89
35 + 3y = $89
3y = $54
y = $18
Hence x = $7 and y = $18
So Shirt = $7 and Sweater = $18
The number m and 58 are additive inverses. Drag and drop 58 and m to their correct positions on the number line.
The value of m which is an additive inverse of 58 is -58.
What numbers are additive inverses?Additive inverse is what you add to a number to make the sum zero. When two numbers are added together to get 0, then we say both the numbers are additive inverses of each other.
Since m is the additive inverse of 58, hence:
m + 58 = 0m = -58
The additive inverse of 58 is -58.

What option gives possible rates and times for two of his jogs
5 mph for 2 hours and 4 mph for 3 hours
4 mph for 2.25 hours and 6 mph for 1.5 hours
gives possible rates and times for two of his jogs
1.Let's determine the relationship between the rate of jogging and the time f jog in each scenario.
First Rate = [tex]\frac{6}{1.5} =4[/tex] time = 1.5 hours
Second Rate = [tex]\frac{5}{1.25} = 4[/tex] time = 1.5 hours
As a result, in this instance, the duration of his runs does not appear to be inversely related to their intensity.
2.First Rate = [tex]\frac{5}{2} =2.25[/tex] time = 2 hours
Second Rate = [tex]\frac{4}{3} =1.33[/tex] time = 3 hours
Therefore, in this instance, the duration of his runs appears to be inversely related to his pace.
3.First Rate = [tex]\frac{4}{2.25}[/tex]=1.77 time = 2.25 hours
Second Rate = [tex]\frac{6.5}{1.5} =4[/tex] time = 1.5 hours
Therefore, in this instance, it appears that the duration of his runs is inversely related to his speed.
4.First Rate = [tex]\frac{4.5}{3}[/tex]=1.5 time = 3 hours
Second Rate =[tex]\frac{6}{4} =1.5[/tex] time = 4 hours

to shift the function up, you need to add -4x by 4
and to shift the function to the left you need to add 1 by 6
Triangle STU with vertices S(- 1, - 6); T(0, - 3) and U(3, - 4) in the line y = - x
Triangle STU have vertices S'(6,1); T'(3,0) and U'(4,-3) after reflection across y = -x.
The triangles is reflected across the line y = -x.
If any point A(a,b) is reflected across y = -x then the coordinates of x and y axes will be interchanged and the coordinates will become negative,
So the reflected point A' will be (-a,-b).
So, after reflection,
S(-1,-6) will become S'(6,1) after reflection across y = -x.
T(0,-3) will become T'(3,0) after reflection across y = -x.
U(3,-4) will become U'(4,-3) after reflection across y = -x.

Let x be the total weight of the silver alloy costing $3.50 per ounce and y be the the total weight of the other that costs $7.00 per ounce.
The total weight of the resulting alloy is 30 ounces.
x+y=30x+y=30
Each ounce of the mixture must cost $6.30. The total cost of the resulting silver alloy is:

8 ounces of silver alloy that costs $5.50 per ounce should be mixed with 12 ounces of silver alloy that costs $8.00 per ounce to make a new 20-ounce alloy that costs $7.00 per ounce.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the number of ounces of silver alloy which costs $5.50 per ounce and y be the number of ounces of silver alloy that costs $8.00 per ounce.
We have,
x + y = 20
5.50x + 8.00y = 7 × 20
From the first equation, x = 20 - y
Substituting this in the second equation,
5.5 (20 - y) + 8y = 140
(5.5 × 20) - 5.5y + 8y = 140
110 + 2.5y = 140
2.5y = 30
y = 12
x = 20 - y = 20 - 12 = 8
Hence the number of $5.50 cost per ounce silver alloy used is 8 ounces and the other alloy used is 12 ounces.

A physics student walks 100 meters in 80 seconds. The student stops for 30 seconds, and then walks 200 meters farther in 90 seconds. What is the average speed of the entire walk?.
The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.
What is the average speed?
The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.
The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.
Given the distance covered by a student in first 80 sec = 100m
After stooping for 30sec again cover a distance of 200m in 90sec.
The total distance traveled by the student = 100 + 200 = 300m
The time taken by student to cover distance = 80 + 30 +90 = 200 sec
The average speed of the student = total distance/ total time taken
= 300/200 = 1.5 m/s
Therefore, the average speed of the student is equal to 1.5m/s.

Answer:
y - 1 = - 3(x + 8)
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
• Parallel lines have equal slopes
the equation ofa line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = - 3 and (a, b ) = (- 8, 1 ) , then
y - 1 = - 3( x - (- 8) ) , that is
y - 1 = - 3(x + 8)
