2(x+1.25)=3,5

Find x

Answer:

i believe it's b:))

Step-by-step explanation:

Answer:

I don't know but I am pretty sure it can't be C or D.

Step-by-step explanation:

The slope of line CD simplifies to 2, so for the perpendicular line to be perpendicular, it must be an opposite reciprocal, meaning -1/2 or -0.5. I don't know what B equals though, whether it is positive or negative.

Hope that helps. (:

Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

Step-by-step explanation:

Given that:

x-4y = 2

2x+y = 12

For elimination, one of the variable is eliminated.

In this system,

we can either multiplying the first equation by 2 or second equation by 4.

Then we can add the equations.

By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.

4(2x+y=12)

8x+4y=48

By adding

(x-4y)+(8x+4y)=2+48

7x=48

Hence,

Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

Answer:

7/12

Step-by-step explanation:

The nth term Tₙ = n(n-4) /n+3.

The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4

The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3

So,  the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3

= (-9 + 16)/12

= 7/12

Answer:

Answer will be 4

Step-by-step explanation:

Okay, again solve all the exponents.

16^5/4=32

16^1/4=2

Multiply 32x2= 64

For the denominator:

16^1/2= 4

4^2= 16

Your left with 64/16

Divide 64/16 and that will give you 4

$150012.84 or $150013 rounded

The growth factor is 1.07

Step-by-step explanation:

First create the equation:

y=1.07x+150,000

Then substitute:

y=1.07(12)+150,000

Calculate:

y=150012.84

Answer:

x=2

Step-by-step explanation:

Since rectangles have 90* angles at each corner, we can say the two equations in the corner equal to 90*

so,

13x+34+10x+10=90

23x+44=90

23x=46

x=2

Answer: >72

Answer:

ΔPQR is a isosceles triangle

Step-by-step explanation:

P (0,0) Q (2,0) R (1,3)

PR² = (3-0)² + (1-0)² = 10

RQ² = (3-0)² + (1-2)² = 10

PR = RQ

ΔPQR is a isosceles triangle

Answer:

you will get speed on a slope and you will get speed with speed  (:

Step-by-step explanation:

Answer:

The joint dependence of locomotive power on speed and slope is crucial in the non-stationary conditions where the skier passes high and low points along the track where both speed and slope change rapidly.

Step-by-step explanation:

Hope this helps you and also when your going down a slope there is movement which in this case you will pick up speed. If your trying to go up a slope your not going to move as fast rather slow.

Answer:

Step-by-step explanation:

The information gives the Slope and y intercept of the line for stock A. At 9am, time = 0, the stock price is $15.11, the y intercept or b. The Slope of the line is 12 cents per hour, it is a positive Slope so it will rise from left to right.

The line in Slope form is

y= 0.12x+15.11

Stock B at noon, so 3 hours later, is $15.86 and is decreasing at a rate of 11 cents per hour.

We know the Slope is -0.11 and we know a point on its line is (3,15.86). From this we can solve for the y intercept by substituting the x and y values from the coordinate into the Slope equation.

15.86 = -0.11(3) + b

15.86 = -0.33 + b

Add 0.33 to both sides

16.19 = b so the equation of the line of stock B is y= - 0.11x + 16.19

Since we have two equations solved for y, we can set them equal to each other and solve for x

0.12x + 15.11 = - 0.11x + 16.19 add 0.11x - 15.11 to both sides

0.23x = 1.08 divide both sides by 0.23 to solve

x = 4.69565 to the nearest tenth 4.7 hours after 9am the two stocks will be the same price.
