Answer:

Open circle. Points right

Step-by-step explanation:

The reason for it is because this symbol > represents greater than when it comes to inequalities. When it is an open circle that means that you are not including the number. So that also means that the -2.5 is not included to the inequality equation but it can be any other number other than that number.

Solve x^2 +14x=15 by completing the square

ivanzaharov [21]

Answer:

x = -15 and x = 1

Step-by-step explanation:

Since we have to use the complete the square method, we first need to rewrite the equation in the form $x^{2}+2ax+a^{2}=(x+a)^{2}$ .

This results in $x^{2} + 14x + 7^{2} = 15 + 7^{2}$ .

Next, we simplify the equation to get $x^{2} +14x+7^{2} = 64$ .

Factoring the left side gives us $(x+7)^{2} = 64$ .

Finally we solve the equations: $x+7=\sqrt{64}$ and $x+7=-\sqrt{64}$ .

This gives us x=1, and x=-15

A square garden with side length of 50 has a square shaped fountain display with length of 12 feet at the exact center of garden

nadezda [96]

Answer:

The area of the garden is $2356\ ft^2$

Step-by-step explanation:

Area of a Square

Given a square of a side length of x, the area is calculated as:

$A = x^2$

There is a square garden area of a side length of x=50 feet. The area is:

$A_1=50^2=2500\ ft^2$

Inside of it, there is another square area for a fountain display of a side length of 12 feet. The area is:

$A_2=12^2=144\ ft^2$

The area of the garden is the difference between A2 and A1:

$A_g=A_2-A_1=2500\ ft^2-144\ ft^2$

$A_g=2356\ ft^2$

If Kiri has 17 part-time members this month, how many full-time members does she need according to your equation?

Zigmanuir [339]

Answer:

5050 = 225f + 125p

If p = 17 this month, then, f = 13

Step-by-step explanation:

Kiri owns a coworking space that has two primary types of memberships, full time and part-time. In order to pay her bills each month (rent on the building, electricity, internet, and so on) she needs to make $5050. Full-time memberships (f) cost $225 per month, and part-time memberships (p) cost $125 per month.

If Kiri has 17 part-time members this month, how many full-time members does she need according to your equation?

Total cost = $5050

cost of full-time memberships = $225

number of full time members = f

cost of part-time memberships = $125

number of part-time members = p

Total cost = cost of full-time memberships * number of full time members + cost of part-time memberships * number of part-time members

5050 = 225f + 125p

If p = 17 this month,

5050 = 225f + 125p

5050 = 225f + 125(17)

5050 = 225f + 2,125

5050 - 2,125 = 225f

2,925 = 225f

f = 2,925/225

f = 13

number of full time members = f = 13

If p = 17 this month, then, f = 13

Simplify the given expression. (See attachment)

stepladder [879]

Working on x and y first, we get: x6 / x3= x3 and y6/ y12 = 1/ y6 so, we have: 2 x3 / y6
Entering values in original equation, we get:
(2 x3/ y6)^2=4 x^6 / y^12
