Step-by-step explanation:

Hope it helps :)

a) 2y = -3x -8

dividing through by 2

y = -3x/2 -4

b) 2y + 3x = 6

2y = -3x +6

dividing through by 2

y = -3x/2 + 3

Given:

Line a passes through (2, 10) and (4, 13).

Line b passes through (4, 9) and (6, 12).

Line c passes through (2, 10) and (4, 9).

To find:

Which of the lines, if any are perpendicular.

Solution:

If a line passes through two points, then the slope of line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Line a passes through (2, 10) and (4, 13).  So, slope of this line is

[tex]m_a=\dfrac{13-10}{4-2}=\dfrac{3}{2}[/tex]

Line b passes through (4, 9) and (6, 12).  So, slope of this line is

[tex]m_b=\dfrac{12-9}{6-4}=\dfrac{3}{2}[/tex]

Line c passes through (2, 10) and (4,9).  So, slope of this line is

[tex]m_c=\dfrac{9-10}{4-2}=\dfrac{-1}{2}[/tex]

Product of slopes of to perpendicular lines is -1.

[tex]m_a\cdot m_b=\dfrac{3}{2}\times \dfrac{3}{2}=\dfrac{9}{4}\neq -1[/tex]

[tex]m_b\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]

[tex]m_a\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]

Therefore, any of these lines are not perpendicular to each other.

Answer:

7.70%

Step-by-step explanation:

Total length of race = 5k

Actual time taken to run the race = 26 minutes

Marcos time = 28 minutes

Percentage error = difference in value / actual time × 100

= (28 - 26) / 26 × 100

= 2 / 26 × 100

= 0.077 × 100

= 7.70%

Answer:

7.7 or 7.70

Step-by-step explanation:

Step-by-step explanation:

Total length of race = 5k

Actual time taken to run the race = 26 minutes

Marcos time = 28 minutes

Percentage error = difference in value / actual time × 100

= (28 - 26) / 26 × 100

= 2 / 26 × 100

= 0.077 × 100

= 7.70%

Answer:

I think the answer is 209

Step-by-step explanation:

6(green): 5(red)

if we divide 95 by 5 we get 19.

Lets multiply 6 by 19 and we get 114.

114 plus 95 is 209.

Answer:

27

Step-by-step explanation:

Subtract the faster speed:

721.6 - 8.4 = 713.2

Divide by 2 trains:

713.2/2 = 356.6

The slower train is going 356.6 miles per hour.

The faster train is going 356.6 + 8.4 = 365 miles per hour.

Answer:

  Yes, these rates are equivalent because the unit rate of 6 laps per minute matches each rate.

Step-by-step explanation:

In each case we have ...

  laps/minutes = (42 laps)/(7 minutes) = 6 laps/minute = (48 laps)/(8 minutes)

Yes, the rates are both 6 laps/min, so are equivalent.

Answer:

Step-by-step explanation:

The opposite angles of the parallelogram are the same.

From the diagram;

<S = <U and <R = <T

Given

<S = 70°

Since <S = <U, hence <U = 70°

Since the sum of angles in a quadrilateral is 360 degrees, hence;

<R+<S+<T+<U = 360

Since <R = <T, then;

<Y+<S+<T+<U = 360

2<T + 70+70 = 360

2<T = 360-140

2<T = 220

<T = 220/2

<T = 110°

Since <T = <R, then < R = 110°

Hence m∠R = 110°, m∠T = 110°, m∠U = 70°. Option B is correct

Answer:

C and B

Step-by-step explanation:

in x=5.9x-19.5 the y int is -19.5 (y=mx+b m = slope b =y int)

According to the information they earn 5.9 of something "every payday" and the y int is them starting out. The only logical answer is C for the first question because every other answer involves slope and not starting value.

For the second one it is B i think since causation means cause to effect or ratio. They are the only values that make since because they are related to eachother.

Sorry for the bad spelling if you need any more information please ask in comments :)

The answers of question 1 and question 2 are option C and B respectively.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

Given equation,

y = 5.9x - 19.5

And we have the slope intercept form

y = mx + b,

where m is the slope and b is the y-intercept.

Comparing above of both the equation,

Here, the y intercept is -19.5 and the slope is 5.9

According to the information they earn 5.9 of something "every payday" and the y intercept is them starting out.

The answer is C for the first question because every other answer involves years that means slope and not starting value.

For the second one,

answer is B i think since causation means cause to effect or ratio.

The positive Correlation between the number of typing classes a student takes and the number of words per minute the student can type.

Relation is directly related to each other.

Therefore, the answers of question 1 and question 2 are option C and B respectively.

Answer:

He will read 72 chapters in 1 day

Step-by-step explanation:

Let us use the ratio method to solve this question

∵ Sam read 6 chapters in 2 hours

∵ He continues to read at this same rate for 1 day

→ We must change the day to hours

∵ 1 day = 24 hours

∴ We need to find how many chapters he will read in 24 hours

→ Chapter  :  Hour

→   6            :   2

→   x            :   24

→ By using cross multiplication

∵ x × 2 = 6 × 24

∴ 2x = 144

→ Divide both sides by 2

∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{144}{2}[/tex]

∴ x = 72

∴ He will read 72 chapters in 1 day

Step-by-step explanation:

1x = [tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]

[tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]+ [tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]= [tex]\frac{d}{dx} }x^2[/tex]

[tex]\frac{d}{dx} }x^2[/tex] = 2x
