Answer:

3x + 4y = 12 \\ 3x - 4y = 5 \\ 6x = 17 \\ x =  \frac{17}{6}  \\ 3 \times   \frac{17}{5}  - 4y = 5  \\ 51 \div 5 - 4y = 5 \\  \\ 10.2 - 5 = 4y \\ y =  \frac{5.2}{4}

Find X in the figure below.
Hitman42 [59]
<h3>Answer:</h3>

x = 3

<h3>Explanation:</h3>

The product of the lengths of segments from the intersection point to the circle is the same for both secants.

... 1×6 = 2×x

... 6/2 = x = 3 . . . . . divide by 2

_____

<em>Comment on secant geometry</em>

Interestingly, this relation is true whether the point of intersection of the secants is inside the circle or outside.

When it is outside, the product is of the distance to the near intersection with the circle and the distance to the far intersection with the circle.

* WILL GIVE BRAINIEST*
k0ka [10]

Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

log_{10}(y) = 2.447

In order to find the value for y, one must simply apply the following logarithmic property:

if : log_{b}(a) = c

then: b^c = a

Applying it to this particular problem:

log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280

Therefore, the regression line predicts y will equal 280 when x equals 5.
