alexandr402 [8]3 years ago
3 0

Answer:

4.3 cm

Step-by-step explanation:

By the theorem of intersecting secants outside of a circle.

3 \times (y + 3) = 2 \times (2 + 6 + 3) \\ 3(y + 3) = 2 \times 11 \\ 3y + 9 = 22 \\ 3y = 22 - 9 \\ 3y = 13 \\ y =  \frac{13}{3}  \\ y = 4.3 \: cm

Find the midpoint of the line segment whose endpoints are (2.6,5.1) and (3,4.7).
svp [43]

Answer:

Mid point is: (2.8;4.9)

Step-by-step explanation:

To find midpoint of a line segment we can use the general equation:

Mid=\frac{x_1+x_2}{2} ;\frac{y_1+y_2}{2}

Where the point of the line are: (x₁;y₁) and (x₂;y₂).

In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:

Mid=\frac{2.6+3}{2} ;\frac{5.1+4.7}{2}

<h3>Mid point is: (2.8;4.9)</h3>

(x - 5) (x + 1)

Step-by-step explanation:

x² - 4x - 5

= x(x + 1) - 5(x + 1)

= (x - 5) (x + 1)

What is the slope of the line with an equation of 5x + 8y = 16?<br> -8/5<br> -5/8<br> 5/8<br> 8/5
zzz [600]

Answer:

Slope m = -5/8

Step-by-step explanation:

5x + 8y = 16

Making y as subject of formula

8y = -5x + 16

Dividing each term by 8

8y/8 = -5x/8 + 16/8

y = -5x/8 + 2

Comparing with y = mx + c

Where m = slope and c the y intercept

Slope m = -5/8
