On a road map, the distance from Green mount to Yorktowne is 2 inches. The map scale is
1 inch : 25 miles. How many miles is the actual distance between the two cities?
Mark only one oval.

A-12.5 miles
B-25 miles
D-50 miles
C-125 miles

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2

tan 30 = perpendicular / base = x/ 7

1/√3 = x/7

X= 7/√3

2.

cos 30 = 7/y

√3/2 = 7/y

y = 7×2/ √3

y= 14/√3

Answer: 468.75

is ya answer

i think

sorry if im wrong

Answer:

468.75

Step-by-step explanation:

First we need to add 25% to 500.00 which is 625.

Next we need to subtract 25% from 625.

Now we have 468.75.

The selling price of the couch is $468.75.

Answer: 38

Step-by-step explanation:

Answer:

Perimeter= 38, EC- Area= 19.5

Step-by-step explanation:

substitute all the x's for 5. simplify each equation. H=3, Base= 13, 4x+2=22

h- 5-2=3

4(5)+2=22

base- 2(5)=3=13

then add all answers together to get 38.

multiply 13 and 3 to get 39, then divide by 2 to get 19.5 for the area.

Answer:

B.

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

if the interest is not compounding then it's called simple interest

which is shown through the following equation

PV(1+it)

plug in what we know and get

50(1+.1*1)

50*1.1=55

which means he'll earn 5 dollars interest in one year

Answer:

8x-(-4x-6)=42

8x+4x+6=42

12x=42-6

12x=36

x=36/12

x=3

substitute in an equation of your choice

8(3)-y=42

24-y=42

24-42=y

-18=y

Step-by-step explanation:

Answer:

x= 4 y= -10

Step-by-step explanation:

8x - y = 42

-4x - 6 = y

rearrange -4x - 6 =y to -4x -y = 6

8x - y = 42

-4x - y = 6

4x = 48

48/4 = 12

x=4

subsitute x with 4 adn solve for y = -22

Answer:

56 degrees

Step-by-step explanation:

we know the right triangle has a 90 degree angle, so we add 90 + 34 to get 124

once we have that down we subtract 124 from 180 to get 56

the reason we subtract from 180 is because the sum of all the angles in a triangle equals 180

Answer:

[tex]x^{2}[/tex]-25

Step-by-step explanation:

formula for areas of rectangles= width x height

width=x-5

height=x+5

(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25

since the 5x's cancel out each other

              =[tex]x^{2}[/tex]-25 will be the answer

The area of rectangle is [tex](x^{2} -25)[/tex] unit square.

The area of rectangle is product of length and width.

         [tex]Area = length*width[/tex]

Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].

    [tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]

Hence, the  area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3
