PLEASE HELP ASAP!!! 98 POINTS FOR ONE MULTIPLE CHOICE QUESTION!!! I DO NOT HAVE PICTURES BUT ANYONE IN FLVS PLEASE ANSWER!!!
sladkih [1.3K]

y = −2x + 13


y = 2x − 3


Set the equations to equal and solve for x:

-2x + 13 = 2x -3

Add 2X to each side:

13 = 4x -3

Add 3 to each side:

16 = 4x

Divide both sides by 4:

x = 16/4

x = 4


Now replace x with 4 in one of the equations and solve for y:


y = -2(4) +13

y = -8 +13

y = 5


x = 4 and y = 5 , which is the ordered pair (4,5)

Both numbers are positive values, so the second graph is correct.

We can find the length of DE using the Pythagorean Theorem:
prohojiy [21]
What's the difference between A) and C)??
There should be an E) because the correct answer would be in either of these forms:
{DE}^{2}  =  {(4 - 1)}^{2}  +  {(1 - 3)}^{2}  \:  \: or \\  DE  =  \sqrt{( {3}^{2}  +  {2}^{2} )} \:   \: or \\  {DE}^{2}  =  {(4 - 1)}^{2} +  {(3 - 1)}^{2}

What is the value of x rounded to nearest tenth
Ivahew [28]

Answer:

6.5 cm

Step-by-step explanation:

Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.

That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.

Simplify: <em>408.04 = 216.09 + 29.4x</em>

Subtract: <em>191.95 = 29.4x</em>

Divide: <em>x = 6.528911565</em> ≈ 6.5 cm
