For C it's y= 1.5x and D is y=2/3x

Answers

y2-y1/x2-x1 = 75-30/50-20
= 45/30 = 1.5
y = 1.5 x
Answer is C

Answer:

y = 1.5x + 0 or y = 1.5x

Step-by-step explanation:

=> First lets find the slope:

Slope: Change in y / Change in x

Change in y = +15

Change in x = 10

Slope = 15/10 or 1.5

=> Now lets find the, y-intercept:

We know that y-intercept is the y-value when x = 0

So we can say:

y = 1.5x

y = 1.5(0)

y = 0

Therefore y-intercept = 0

Final equation: y = 1.5x + 0 or y = 1.5x

Solve 9x + 3 = -33 . PLEASE HELP ME IT WILL MAKE MY DAY​

Answers

[tex] : \implies \sf 9x + 3 = - 33[/tex]

[tex] : \implies \sf 9x = - 33 - 3[/tex]

[tex] : \implies \sf 9x = - 36[/tex]

[tex] : \implies \sf x = \dfrac{ - 36}{9} = - 4[/tex]

[tex] \therefore \sf x = -4 [/tex]

Answer is x = -4

Arrange the equation so that +3 goes to the other side by subtracting -3 from both sides.

The equation then becomes 9x = -36

Afterwards, to separate the 9 from the x, you divide 9 on both sides.

The equation then becomes x = -36/9, where -36 divided by 9 is -4.

The equation is then left with x = -4 where you have solved x.

Hope this helps!

In parallelogram ABCD, AE = 2x - 10 and EC = 8x - 70. Find x.

x =??

Answers

Answer:

x = 10

Step-by-step explanation:

According to Midpoint of a segment theorem we can say that AE = EC

So,

2x - 10 = 8x - 70

=> First subtract 2x from each side of "="

-10 = 6x - 70

=> Now add 70 to both the sides.

60 = 6x

=> Lastly divide both sides of "=" by 6

10 = x

According to question,

= 8x² + 6x - 2 = 228

= 8x² + 6x - 230 = 0

= 2(4x² + 3x - 115) = 0

= 2(4x² + 23x - 20x - 115) =0

= 2(x(4x +23) -5(x - 23) )= 0

= 2((x-5)(4x+23)) = 0

x = 5 , x = -23/4

let x = 5

so length 4x - 1

width = 2x + 2

Consider the function g(x) = (x-e)^3e^-(x-e). Find all critical points and points of inflection (x, g(x)) of the function g.

Answers

Answer:

The answer is "[tex]cirtical\ points \ (x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})[/tex]"

Step-by-step explanation:

Given:

[tex]g(x) = (x-e)^3e^{-(x-e)}[/tex]

Find critical points:

[tex]g(x) = (x-e)^3e^{(e-x)}[/tex]

differentiate the value with respect of x:

[tex]\to g'(x)= (x-e)^3 \frac{d}{dx}e^{e-r} +e^{e-r} \frac{d}{dx}(x-e)^3=(x-e)^2 e^{(e-x)} [-x+e+3][/tex]

critical points [tex]g'(x)=0[/tex]

[tex]\to (x-e)^2 e^{(e-x)} [e+3-x]=0\\\\\to e^{(e-x)}\neq 0 \\\\\to (x-e)^2=0\\\\ \to [e+3-x]=0\\\\\to x=e\\\\\to x=e+3\\\\\to x= e,e+3[/tex]

So,

The critical points of [tex](x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})[/tex]

O  A. 8

Step-by-step explanation:

the line is 180, so subtract 140 to get 5x. 5x = 40 so divide by 5

180 - 140 = 5x

         40 = 5x

          /5    /5

            8 = x

Answer: X=8

Step-by-step explanation:

it is a 180 degree angle total.

180=5x+140

subtract 140 from both sides

40=5x

divide by 5 on both sides

lacy work 15 hours last week she was paid $127.50 what is your hourly pay

Answers

Given:

Lacy work 15 hours last week and she was paid $127.50.

To find:

The hourly pay of Lacy.

Solution:

We have,

15 hours pay = $127.50

To find the hourly pay of Lacy, we need to divide total pay by number of hours.

[tex]\text{Hourly pay}=\dfrac{\text{Total pay}}{\text{Number of hours}}[/tex]

[tex]\text{Hourly pay}=\dfrac{127.50}{15}[/tex]

[tex]\text{Hourly pay}=8.5[/tex]

Therefore, the hourly pay of Lacy is $8.50.

A 90 clockwise rotation and then a vertical reflection are applied to the scalene triangle. which figure represents the result of the transformation?(please help soon)

Answers

The figure that represent the rotation and reflection of the scalene triangle is given as follows:

Figure B.

What are the rotation rules?

The five more known rotation rules are given as follows:

90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)

A 90º clockwise rotation means that the scalene triangle is rotated right, and thus the figure would be given by option D.

After the vertical reflection, the orientation of the triangle would be changed, meaning that it would then be given by option B.
