a) through (7, 1) and perpendicular to y=-x+ 3

Answers

Answer 1

Step-by-step explanation:

Two lines that are perpendicular to each other has -1 as the product of thir gradient.

Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.

So y = x + c.

When x = 7, y = 1. 1 = 7 + c, c = -6.

Hence the equation of the line is y = x - 6.

The difference of a number n and the number 8 is 42. Which of
the following equations represents this statement?

A)n/8 = 42
B) n - 8 = 42
C)n + 8 = 42
D) 8n = 42
E) n = 5

Answers

Answer:

B) n-8=42

Step-by-step explanation:

"difference" means subtraction.

the number is represented by "n" in this problem.

"and" indicates where the symbol goes.

"is" means "=".

The equation that represents the given statement should be n-8 = 42.

Given that

The number n and the number 8 difference should be 42.

Based on the above information,

We know that the difference means subtraction.

John went on a bike ride to the store 4 miles away. If it took 3/10 of and hour to get there and 1/2 of an hour to get back, what was his average rate of speed for the entire trip

Answers

Answer:

10mph or 10 miles per hour

Step-by-step explanation:

From the question,

John ride 4 miles to the store and 4 miles back

Total distance travelled = 4 miles + 4 miles

= 8 miles

Total time travelled

Time to the store = 3/10 of an hour

Time back from the store = 1/2 of an hour

Total time travelled

= 3/10 + 1/2

= (3 × 2) +(10 × 1)/20

= 6 + 10/20

= 16/20

= 4/5

Total time travelled= 4/5 hour

His average rate of speed for the entire trip formula =

Speed = Total distance travelled (miles)/ Time (hour)

= 8/(4/5)hour

= 8 ÷ 4/5

= 8 × 5/4

= 40/4miles/ hour

= 10 miles/ hour

Therefore, his average rate of speed for the entire trip is 10 miles/hour

Answers

2 Answers: Choice C, Choice D

=========================================================

Let's go through the answer choices one by one

A) This is false because parallel lines do not cross or intersect. They cannot have a point in common.B) This is false because lines need to cross in order to form a right angle. C) This is true. Parallel lines never intersect. They are the same distance away from one another at any point along either line. One example of parallel lines are the metal tracks in a railroad.D) This is true. Having a point in common means a point is on both lines at the same time, but parallel likes never cross. So they have no points in common.

What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26

Answers

Answer:

x = 26

Step-by-step explanation:

1 / 3 (x - 2) = 1 / 5 (x + 4) + 2

1/3x - 2/3 = 1/5x + 4/5 + 2

1/3x - 1/5x = 4/5 + 2/3 + 2

(5x - 3x)/15 = (12 + 10 + 30) / 15

2x / 15 = 52 / 15

2x = 52

x = 52 / 2

Hello there!

Question:-

[tex]\sf \longmapsto \: m = -12g + x[/tex]

We need to find the value of x.

Solution:-

[tex]\sf \: m = -12g + x[/tex]

Firstly, Over turn the equation:-

[tex]\sf \longmapsto - 12g + x = m[/tex]

Then Add 12 g to both sides:-

[tex]\sf \longmapsto - 12g+x+12g=m+12g[/tex]

This equation may be rewritten as :-

[tex]\sf \longmapsto - 12g + 12 g + x = m + 12g[/tex]

On Simplification:-

As (-) and (+) equals to (-),

[tex]\sf \longmapsto \: 1g + x = m + 12g[/tex]

[tex]\sf \longmapsto \: x = m + 12g[/tex]

______________________________________

Henceforth,the value of x is :-
