Beth and her sisters are going to the state fair. Each ride costs $7, and each exhibit costs $4. The table shows the number of r

Maru [420]

Answer:

7x + 3y </=8

Step-by-step explanation:

Let x represent the number of rides Beth rides and y represent the number of exhibits she views

Each ride costs $7 to ride and each exhibit costs $3 to view

This means that x rides will cost x × 7 = $7x

Also, if she views y exhibits, the cost will be y × 3 = $3y.

Total cost of x rides and y views will be 7x + 3y

if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98

The required expression will be

7x + 3y </=8

E(5,3) and F (2,-1) are two vertices of a square EFGH and H is in the x-axis .Find the coordinates of H and G. Please need answe

timurjin [86]

Answer:

coordinates of H = (1, 0)

Coordinates of G = ( - 3.6, -2) or (5.6, -2)

Step-by-step explanation:

E(5,3) and F (2,-1) are two vertices of a square EFGH and H is in the x-axis.

Let the coordinates of H is (x, 0) and G is (a, b).

The length of side EF is

$EF = \sqrt{(5 -2)^2 + (3 +1)^2} = 5$

So,

$EH = \sqrt{(5 -x)^2 + (3 -0)^2} = 5\\\\(5 -x)^2+ 9 = 25\\\\5 - x = 4\\\\x = 1$

And

$GH = \sqrt{(a -x)^2+ b^2} = 5\\\\(a -1)^2+ b^2 = 25\\\\a^2 + b^2 + 1 - 2 a = 25\\\\a^2 + b^2 - 2a = 24 .... (1)$

Now

$FG = \sqrt{(a -2)^2+ (b +1)^2} = 5\\\\(a -2)^2+ (b+1)^2 = 25\\\\a^2 + b^2 + 2b - 2 a = 20\\ ..... (2)$

Solving (1) and (2)

b = - 2 ,

$a = \frac{2 \pm\sqrt{4 + 80}}{2}\\\\a = \frac{2 \pm 9.2}{2}\\\\a = - 3.6, 5.6$
