3x - 5y - 2x + 3 + 8y + 10

Answer:

155

Step-by-step explanation:

calculate the areas of 2 rectangles

method A

one rectangle with lengths 8 and 10

the other 15 and 5

so 8x10 + 15x5 = 80 + 75 = 155

method B

one traingle with lenghts 5 and 7

the other 15 and 8

so 15x8 + 5x7 = 120 + 35 = 155

Answer:

right triangles are 90 degrees sooooo

add 39 plus 27, that's 66

90 minus 66 issss 24

Answer: 9

Step-by-step explanation:

super easy

basically do 15-5 which is 10

thats the hypotenuse side

now apply pythegorean theorem: 5 squared + x squared= 10 squared

25+ x squared=100

x squared=75

x approxiametly equals 9

Answer:

A) 999.75 </= 15w + (4(13.5))w - 4.5w

B) 999.75 </= 64.5w

C) Can't Graph On Here Sorry

D) 15.5 weeks

Step-by-step explanation:

A)  999.75 </= 15w + (4(13.5))w - 4.5w

B) 999.75 </= 15w + 54w - 4.5w

999.75 </= 69w - 4.5w

999.75 </= 64.5w

C) Just graph it, Price needed being Y (Also money), Times (in weeks) being X

D) 999.75/64.5

w >/= 15.5

Answer:

There would be a 56% increase

Step-by-step explanation:

We need to find the amount of change before we can find the percent of change. We'll take the greater value, 78, and subtract the lesser value, 50. 78 - 50 = 28. We then take this amount of change and put it over the original amount, Percent of change = Amount of change/ original amount or for this problem, 28/50. We then use that as a division equation for 28 divided by 50. 28 divided by 50 = 0.56. Finally we move the decimal to the right two times and we can then find the percentage increase.

Answer:

The slope is:

[tex] \frac{1}{7} [/tex]

Step-by-step explanation:

⁕ Remember that slope formula is:

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

⁕ Let's plug in and solve.

[tex]m =  \frac{ 2 - 1}{4 - ( - 3)}  =  \frac{ 1}{ 7}[/tex]

Therefore, the slope is:

[tex] \frac{1}{7} [/tex]

Stohr sequence

Step-by-step explanation:

Let a_1=1 and define a_(n+1) to be the least integer greater than a_n which cannot be written as the sum of at most h>=2 addends among the terms a_1, a_2, ..., a_n. This defines the h-Stöhr sequence

Answer:

k = 1

Step-by-step explanation:

Given that,

[tex]f(x) = x^3 +kx + 2[/tex]

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

[tex]x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1[/tex]

So, the value of k is 1.

Answer:

60 seconds, 7715 feet

Step-by-step explanation:

Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.

To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.

For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.

Answer:

The equation of the perpendicular bisector line

5 x - 2 y + 31 =0

Step-by-step explanation:

Explanation:-

Given points are ( 0,1) and (-10,5)

The Midpoint of given two points

             [tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]

             (-5 , 3)

The Slope of the line

 m =        [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-1}{-10} = \frac{-2}{5}[/tex]

The perpendicular slope

    =   [tex]\frac{-1}{m} = \frac{-1}{\frac{-2}{5} } = \frac{5}{2}[/tex]

The equation of the perpendicular bisector line

 [tex]y - y_{1} = m (x - x_{1} )[/tex]

 [tex]y - 3 = \frac{5}{2} ( x-(-5))[/tex]

  2 y - 6 = 5( x +5)

    5 x + 25 -2y +6 =0

   5 x - 2 y + 31 =0
