Answer:

k= -14

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex] \frac{5}{3} = \frac{7 - (3 - k)}{k + 3 - ( - 5)} [/tex]

[tex] \frac{5}{3} = \frac{7 - 3 + k}{k + 3 + 5} [/tex]

[tex] \frac{5}{3} = \frac{4 + k}{k + 8} [/tex]

Cross multiply:

3(4 +k)= 5(k +8)

Expand:

12 +3k= 5k +40

Bring k terms to one side, constant to the other:

5k -3k= 12 -40

Simplify:

2k= -28

Divide both sides by 2:

k= -14

12:00pm is the closest to freezing

Answer:

CM = 16

MD = 16

CD = 32

Step-by-step explanation:

To find the value of x

3x + 1 = 8x - 24 (we know that M is the mid point so both of the lines will be equal)

Transpose

1 + 24 = 8x - 3x

25 = 5x

x = 25/5

x = 5

CM = 3x + 1

      = 3(5) + 1

      = 15 +1

      = 16

MD = 8x - 24

      = 8(5) - 24

      = 40 - 24

      = 16

CD = CM + MD

     = 16 + 16

     = 32

Answer:

n

Step-by-step explanation:

m/n = 0

=> m = 0 × n

=> m = 0

n + 0 = n

Step-by-step explanation:

According to the above figure,

RS+ST=RT

4x+12x=32

16x=32

x=32/16

x=2

Now,

ST=12x

ST=12×2

ST=24

Answer:

RST = 20

Step-by-step explanation:

a ray that divides an angle into two equal angles is called an angle bisector.

So RSP = PST

3 x -2 = 9x - 26

6x = 24

x = 4

RST = 3x -2 + 9x -26 = 20

Yes, it's true that Any point that is collinear to points X and Y also lies in the same Z plane among X and Y.

Answer:

h=39/4

Step-by-step explanation:

area of a triangle = 1/2(b*h)

base = 8 inches

area =39 square inches

input the values given:

39=1/2(8*h)

multiply the right side by 1/2

39=(1/2)8h

find half of 8

39=1/2*8 (h)

hence,

39=4h

divide both sides by 4

hence,

39/4=h

Answer:

∠ WMX = 65°

Step-by-step explanation:

∠ WMX = ∠ VMX - ∠ VMW = 90° - 25° = 65°

Answer:

Step-by-step explanation:

Here is your answer

6k+9k<0

Simplify

6k+9k<0

15k<0

divide the sides by 15

15k /15 < 0 /15

1k<0

k<0

Answer: step 5. -11.8+9.8 = -2

Step-by-step explanation:

In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.

The equation of the line is y = (15/2)x + 80.

The slope of the line is 15/2.

We have,

The coordinates from the graph:

(0, 80) (2, 65) and (3, 55).

Now,

The slope can be calculated as:

= (d - b) / (c - a)

where (a, b) and (c, d) are the two coordinates.

Consider (a, b) = (0, 80) and (c, d) = (2, 65)

Slope = (65 - 80) / (2 - 0)

Slope = 15/2

Now,

The equation of  the line:

y = mx + c _______(1)

Where m is the slope and c is the y-intercept.

Consider: (0, 80) = (x, y)

80 = 15/2 x 0 + c

c = 80

And,

Substitute c = 80 and m = 15/2 in (1).

y = (15/2)x + 80

Thus,

The equation of the line is y = (15/2)x + 80.

The slope of the line is 15/2.

Answer:

Jeremy Will have more than just $200 to spend on Christmas presents.

Explanation :

He has a total of $1200.

He spends a $120 for car insurance. (1)

He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)

He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)

adding (1) (2) and (3)

We get Jeremy's total spending will be $840. Jeremy has $1200.

1200-840 = $360

So Jeremy will have $360 to spend on Christmas present.

Answer:

Step-by-step explanation:

JK + KL = JL

x² - 4x +3x - 2 = 28

x² - x - 2 = 28

x² - x -2 - 28 = 0

x² - x - 30 = 0

Sum = -1

Product = -30

Factors = -6 , 5    {-6 + 5 = -1 and (-6)*5 = -30}

x²  + 5x - 6x  - 30 = 0   {Rewrite the middle term}

x(x + 5) - 6(x + 5) = 0

(x + 5)(x - 6)= 0

x -6 = 0     {X +5 = 0 is ignored as measurement will not be negative}

x = 6

JK = x² - 4x

     = 6² - 4*6

     = 36 - 24

JK   = 12

KL = 3x -2

    = 3*6 - 2

    = 18 - 2

KL = 16
