Answer:

Perpendicular slope = – 1/m = -1/3 = -1/3

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-1\right)[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=3[/tex]

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 3

perpendicular slope = – 1/m = -1/3 = -1/3

Thus, the slope of any line perpendicular to GH = -1/3

Answer:

6x3+10x2−16x or A

Step-by-step explanation:

I used an algebra calculator because im too lazy to work it out.  

^algebra^

(3x2 + 8x)(2x − 2)

=3x²(2x-2)

=6x³ - 6x²

+8x(2x - 2)

=16x² - 16x

put it all together

=6x³ - 6x² + 16x² - 16x

group according to variables, then count

6x³ + (-6x² + 16x²) - 16x

=6x³ + (+10x²) - 16x

=6x³ + 10x² - 16x

Answer:

31/8

Step-by-step explanation:

3/1/4 - (-5/8)

13/4 + 5/8

find Lcm of 4 and 8 = 8

multiply their common factors with numerators.

13*2 + 5*1 = 31

=31/8 or 3/7/8 or 3.875

Answer:

3 and 7/8

Step-by-step explanation:

3 1/4 - ( - 5/8 ) = x

13/4 + 5/8 = x

26/8 + 5/8 = x

31/8 = x

x = 3 7/8

Answer:

y=-5/3x+1

Step-by-step explanation:

The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down.  We can also assume that the y-intercept is 1 based on where the slope is placed.

Answer:

12%

Step-by-step explanation:

Original = $874,990

New = $769,991

874,990 - 769,991/874,990

104,999/874,990

0.12

Turn to percentage

0.12 * 100

= 12%

Answer:

12%

Step-by-step explanation:

Given:

Percent change formula

[tex]\sf percent\:change=\left|\dfrac{final\:value-initial\:value}{initial\:value} \right|\times 100[/tex]

Substitute the given values into the formula:

[tex]\begin{aligned}\implies \sf percent\:decrease & = \sf \left|\dfrac{769991-874990}{874990} \right|\times 100\\& = \sf 0.1200002286 \times 100\\& = \sf 12.00002286... \\& = \sf 12\% \end{aligned}[/tex]

Therefore, the Percent of Decrease (markdown) to the nearest percent is 12%.

Answer:

Step-by-step explanation:

1.

a)

Find the vertex by completing the square to answer both a and b

d)

x-ints is when y=0

so use quadratic equation for

b^2-20b+200=0

a=1

b= -20

c=200

But notice these imaginary numbers means 0 x intercepts.

Answer:

I think it is 90 and 100

Step-by-step explanation:

I used this equation: x is the speed of the slower train

910 = (5x + 10) + 5x

Answer:

The answer is 86 and 96 mph

Step-by-step explanation:

Givens

Train A

Distance traveled = d

time taken = 5 hours

rate traveled = r

Train B

Distance traveled = 910 - d

time taken = 5 hours

rate = r + 10

Formula

basically d = r * t

Solution

Train A: d/r = 5 or d = 5*r

Train B = (910 - d)/(r + 10) = 5    or

Substitute d = 5*r   into Train B

(910 - 5*r)/(r + 10) = 5        Multiply both sides by r + 10

(910 - 5r) = 5 * (r + 10)       Remove the brackets on both sides

910 - 5r = 5r + 50             Add 5r to both sides

910 = 5r + 5r + 50

910 = 10r + 50                  Subtract 50 from both sides

910 - 50 = 10r                  Combine the left

860 = 10r

10r = 860                         Divide by 10

r = 860/10

r = 86

r + 10 = 96

Check

Train A distance: 5*r = 5 * 86 = 430

Train B distance: 5*r = 5 * 96 = 480

Total =                                         910
