Answer:
Step-by-step explanation:
Two lines are perpendicular to each other if they both intersects and the two lines are inclined at angle 90°
Since they are inclined at 90° to each other, hence they create right angles.
The lines can also lines on the same plane to form a right angles. This are called coplanar lines.
From the above explanation, the following are true;
I) Perpendicular lines intersect
II) Perpendicular lines create right angles
V) Perpendicular lines are coplanar
They are not collinear because they can't lie on the same straight line. Collinear lines are known to lie on the same straight line.

Katarina wrote the standard form of a linear equation as 4x – 4 x minus StartFraction 2 Over 3 EndFraction y equals 8.Y = 8. Sofiya told her that the equation was not yet in standard form and gave her the right advice for how to fix it. What advice did Sofiya give to Katarina? Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12. Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 8. Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 4.
Answer:
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
Step-by-step explanation:
Katarina's equation
4x - 2/3y = 8
In order to convert Katrina's linear equation into standard form,
She should find the least common denominator
4x - 2/3y = 8
{4x(3) - 2y(1)} / 3 = 8
(12x - 2y) / 3 = 8
Multiply both sides by 3
(12x - 2y) / 3 × 3 = 8 × 3
12x - 2y = 24
Divide both sides by 2
(12x - 2y) / 2 = 24 / 2
6x - y = 12
The advice sofiya gave Katrina is to Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
Answer:
B) Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.

4(2x - 5) -6( ) = 6+9) + (2x - 5)
Answer: x=6
Step-by-step explanation:
Step 1: Remove parentheses.
4(2x-5)-6=6+9+2x-54(2x−5)−6=6+9+2x−5
Step 2: Simplify 6+9+2x-56+9+2x−5 to 2x+102x+10.
4(2x-5)-6=2x+104(2x−5)−6=2x+10
Step 3: Expand.
8x-20-6=2x+108x−20−6=2x+10
Step 4: Simplify 8x-20-68x−20−6 to 8x-268x−26.
8x-26=2x+108x−26=2x+10
Step 5: Add 26 to both sides.
8x=2x+10+268x=2x+10+26
Step 6: Simplify 2x+10+262x+10+26 to 2x+362x+36.
8x=2x+368x=2x+36
Step 7: Subtract 2x2x from both sides.
8x-2x=368x−2x=36
Step 8: Simplify 8x-2x8x−2x to 6x.
6x=36
Step 9: Divide both sides by 6.
x= 36/6 as a fraction
Step 10: Simplify \frac{36}{6} to 6.
x= 6x
[tex] \bold{4(2x - 5) -6 = 6+9) + (2x - 5)}[/tex]

You drive to visit your parents, who live 100 miles away. Your average speed is 50 miles per hour. On arrival, you stay for five hours and then return home, again at an average speed of 50 miles per hour. Which graph depicts your distance from home from the time you leave until you return?
Answer: The first graph is the answer.
Step-by-step explanation: If your parents house is 100 hours away, and you're driving at 50 mph, then it would take 2 hours to get to you're parents house (100 ÷ 2 = 50). Then you stay at your parents house for 5 hours (2 + 5 = 7), the graph stays the same place on the y axis for 5 hours. Afterwards you drive home, same distance as when you drove to your parents (2), but you're going back so it's going down. This makes graph 1 the answer.

Solve for x. Enter the solutions from least to greatest. (2x +4)(3x -2)=0
-0.4
Step-by-step explanation:
You need to combine like terms, whatever that means. So you would add 2x and 3x to get 5x, and then 4+(-2), which would get you to 5x+2=0. Next, you subtract 2 from both sides, so you have 5x=(-2), and then you have to divide both sides by 5.
That's how I got x=(-0.4).

Your family drives across Kansas on Interstate 70. A sign reads, “Wichita 90 mi, Topeka 110 mi”. What is the possible range of distances between the two cities given that the cities are not collinear?
Answer:
20 miles < The distance between the cities < 200 miles
Step-by-step explanation:
The given information on the sign = "Wichita 90 mi, Topeka 10 mi"
Given that the two cites are not colinear, we have;
The number of points specified in the figure = 3 points
The specified points are;
1) The location of the family
2) The location of Wichita, relative to the family's location, = 90 mi
3) The location of Topeka, relative to the family's location, = 110 mi
Therefore, given that the three points are not colinear, they form the vertices of a triangle
The legs of the triangle are 90 mi and 110 mi
The maximum distance between Wichita and Topeka is therefore = 90 + 110 = 200 miles
The minimum distance distance from Wichita to Topeka = 110 - 90 = 20 miles
Therefore, the possible range of distances between the two cities is 20 miles to 200 miles.
Which gives;
20 miles < The distance between the cities < 200 miles.
The curved surface area of a right circular cylinder of height14 cm is 88 cm2. Find the diameter of the base of the cylinder.
Answer:
4
Step-by-step explanation:
The formulae for Curved surface
area = πrh
Area = 88cm2
height = 14cm
radius = ?
Let π be 22/7
88 = 22/7 x r x 14
cross multiply
88 x 7 = 22 x 14 x r
616 = 308r
Divide both sides by 308
r = 2
Diameter = Radius x 2
so our radius is 2, 2 x 2 = 4
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 6 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation. Complete the steps below to solve the problem.
Step-by-step explanation:
At the elevation 617.5 feet below the sea level temperature of the water was °F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is °F
When submarine dives down 115 feet deeper, water temperature drops by °F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be =

= °F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was °F

A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be made measures The longest side of the drawing measures The longest side of the actual triangular piece to be sculpted must be long. How long will the shortest side of this piece be?
Answer:
3.71 m
Step-by-step explanation:
Here is the complete question.
A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be made measures 7 cm. The longest side of the drawing measures 20 cm. The longest side of the actual triangular piece to be sculpted must be 10.6 m long. How long will the shortest side of this piece be?
Solution
This is a scale drawing question.
Since scale = Scaled size/Actual size, we need to find the scale ratio of the triangle.
Now, the longest side of the drawing measures 20 cm which is equal to the scaled size and the longest side of the actual triangular piece to be sculpted is 10.6 m long which is the actual size.
So, scale = 20 cm/10.6 m
= 0.2/10.6
= 1/53.
Since in the scale drawing, the shortest side of the triangular piece to be made measures 7 cm, this is the scaled size, so the actual size of the shortest side is gotten from
scale = Scaled size/Actual size.
So,
Actual size = Scaled size/scale
= 7 cm ÷ 1/53
= 53 ×7 cm
= 371 cm
= 3.71 m

Consider the expression –4b + 8c + 12 – 8b – 2c + 6. Part A Simplify the expression. b + c + Part B Factor the simplified expression using the GCF. 2(–2b + c + 3) 3(–2b + c + 3) 4(–2b + c + 3) 6(–2b + c + 3) Part C What is the value of the expression when b = 2 and c = –3?
Answer:
Step-by-step explanation:
Given the expression
-4b + 8c + 12 – 8b – 2c + 6.
To simplify, first collect the like terms
= (-4b-8b)+(8c-2c)+(12+6)
= -12b+6c+18
Factor out the GCF
The GCF is 6
On factoring out;
= 6(-2b+c+3)
If b = 2 and c = -3 the expression becomes:
= 6(-2(2)+(-3)+3)
= 6(-4-3+3)
= 6(-4+0)
= 6(-4)
= -24
Hence the value of the expression when b = 2 and c = -3 is -24
