Work out m and c for the line: 3 y + 6 x = − 3

Answers

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

[tex]{ \rm{y = mx + c}}[/tex]

m is the slopec is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

[tex]{ \rm{3y + 6x = - 3}}[/tex]

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

[tex]{ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}[/tex]

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

[tex]{ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}[/tex]

Write the equation of the line in slope intercept form the line is parallel to y+x=3 and passes through the point(-12,0)

Answers

Answer:

y= -x -12

Step-by-step explanation:

change y+x=3 to the form y=-x +3

*Parallel lines have the same gradient

y-coordinate = gradient (x - x-coordinate)

y-0= -1 (x- (-12))

y=-x-12

x < 3 and x > -1

Step-by-step explanation:

Step 1: Subtract 2 from both sides.

[tex]|x-1| + 2 - 2 < 4 - 2[/tex] [tex]|x-1|<2[/tex]

Step 2: Solve absolute value.

We know x - 1 < 2 and x - 1 > -2.

Condition 1:

[tex]x - 1 < 2[/tex] [tex]x - 1 + 1 < 2 + 1[/tex] (Add 1 to both sides)[tex]x < 3[/tex]

Condition 2:

[tex]x - 1 > -2[/tex] [tex]x - 1 + 1 > -2 + 1[/tex] (Add 1 to both sides)[tex]x>-1[/tex]

Therefore, the answer is x < 3 and x > -1.

Kadeem wants to ride his bicycle 52 miles this week. He has already ridden 16 miles. If he rides for 5 more days, write and solve an equation which can be used to determine xx, the average number of miles he would have to ride each day to meet his goal.
How to solve this for an equation.

Answers

The average number of miles that would be ridden to meet his goal is 7.2 miles.

Total distance = 52 miles

Distance ridden = 16 miles

Number of days left = 5 days

Let the number of miles that'll be ridden for each day be represented by x.

Therefore, the equation to solve the question will be:

5(x) + 16 = 52

5x + 16 = 52

5x = 52 - 16

5x = 36

x = 36/5

x = 7.2

Therefore, he'll have to ride 7.2 miles per day.

which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5

Answers

w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.

For the Expression -w - 3 > -5

-w > -5 + 3

-w > -2

w < 2

Since w is less than 2, hence the inequality is wrong

For the inequality

-w - 3 > 5

-w > 5 + 8

-w > 13

w < -13

Since w < -13, hence the inequality is wrong

For the inequality w > -5

It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

Step-by-step explanation:

let the speed of diesel train = x

the equation would be:
