Answer:

3 $\frac{3}{4}$ , 4 $\frac{1}{4}$ , 4 $\frac{1}{2}$ (two x's on this spot), 5

Step-by-step explanation:

you need an x in each point (A, B, C, D, E) given in the chart

notice point B and E are the same

3 $\frac{3}{4}$ , 4 $\frac{1}{4}$ , 4 $\frac{1}{2}$ (two x's on this spot), 5

I believe the bottom left shows the right answer

Y is between points p and b. pt= 15 and tb = 10. what is pb

Kruka [31]

PT = 15, and TB = 10

Take the 15 from PT, and add the 10 from TB. Which equals 25.

PB = 25

So, 25 is your answer.

Hope this helps! ☺

In Exercises 10 and 11, points B and D are points of tangency. Find the value(s) of x.

Lemur [1.5K]

In both cases,

$AB^2=AD^2$

(as a consequence of the interesecting secant-tangent theorem)

So we have

10.

$(4x+7)^2=(6x-3)^2$

$16x^2+56x+49=36x^2-36x+9$

$20x^2-92x-40=0$

$5x^2-23x-10=0$

$(5x+2)(x-5)=0\implies\boxed{x=5}$

(omit the negative solution because that would make at least one of AB or AD have negative length)

11.

$(4x^2-18x-10)^2=(x^2+x+4)^2$

$16x^4-144x^3+244x^2+360x+100=x^4+2x^3+9x^2+8x+16$

$15x^4-146x^3+235x^2+352x+84=0$

$(x-7)(3x+2)(5x^2-17x-6)=0\implies\boxed{x=-\dfrac23\text{ or }x=7}$

(again, omit the solutions that would give a negative length for either AB or AD)

6 is 3% of what number?

Aleks04 [339]

✡ Answer: 200 ✡

- - Solve:

✡ First we need to find the formula to solve:
$\frac{3}{100} * x=6$

✡ Now:
x is equal to: $\frac{100*6}{3}$


✡Now we are going to multiply $100*2$ to get our answer.

- - 100*2=200 

✡Hope this helps!✡
