Secant and Tangent Angles in circles. <br>Solve for x.<br>

poizon [28]

Answer:

x = 1

Step-by-step explanation:

5x + 17 = 1/2[(73x + 5) - (23x - 5)]

5x + 17 = 1/2[37x + 5 - 23x + 5]

5x + 17 = 1/2[14x + 10]

5x + 17 = 1/2 * 2(7x + 5)

5x + 17 = 7x + 5

5x - 17x = 5 - 17

-12x = - 12

x = - 12/-12

x = 1

4x-7y=2 -8+7y=-18 please help me hah im confused

ddd [48]

-8 + 7y = - 18
7y =10
y =10/7

Substitute y = 10/7 into first equation
4x - 7 (10/7)=2
4x - 10 =2
4x = 12
x = 3

Thus, the solution is x = 3 and y = 10/7

What is the value of c so that -10 and 10 are both solutions of x2 -c=70?

olga nikolaevna [1]

Answer:

c = 30

Step-by-step explanation:

since:

${(10)}^{2} = { (- 10)}^{2}$

once we find a c value for 10, we know that it will work for - 10 as well

${x}^{2} - c = 70$

we can sub in 10 to get

${10}^{2} - c = 70 \\ c = 100 - 70 \\ c = 30$

A school gymnasium is being remodeled. The basketball court will be similar to an NCAA basketball court, which has a length of 9

valkas [14]

Answer:

Perimeter of NCAA court=288 feet

Perimeter of new court=259.2 feet

Step-by-step explanation:

We are given that

Length of NCAA court, l=94 feet

Width of NCAA court, b=50 feet

Width of new court, b'=45 feet

We have to find the perimeter of an NCAA court and new court in the school.

Perimeter of NCAA court= $2(l+b)$

Perimeter of NCAA court= $2(94+50)$ feet

Perimeter of NCAA court=288 feet

When two rectangles are similar then the ration of their corresponding sides are equal.

Using the property

$\frac{Perimeter\;of\;NCAA\;court}{Perimeter\;of\;new\;court}=\frac{Width\;of\;NCAA\;court}{Width\;of\;new\;court}$

$\frac{288}{Perimeter\;of\;new\;court}=\frac{50}{45}$

Perimeter of new court= $\frac{288\times 45}{50}$ feet

Perimeter of new court=259.2 feet
