Find the measure of CD⎯⎯⎯⎯⎯⎯⎯⎯.<br><br> A. 8<br> B. 6<br> C. 5<br> D. 7

oee [108]

Answer:

Using the property of intersecting secant:-

$(DE)(CE)=(FE)(LE)$

$(4)(x-1+14)=(5)(x-4+5)$

$4(x+3)=(5x+1)$

$4x+12=5x+5$

$4x+-5x=5-12$

$-x=-7$

$x=7$

$So, CD=x-1=7-1=6$

$so,~your ~answer ~is ~B) ~6$

One foot is equal to 12 inches. The function I(f) takes a length in feet (as input) and returns a length in inches (as output).

Delicious77 [7]

You need to substitute the number 6 into the function. The output would be 72, because when l(6) = 12(6), you would get l(6) = 72.

The number 42 is increased to 46. what is the percentage by which the number was increased?

Arte-miy333 [17]

Answer:

9.52% ( to 2 dec. places )

Step-by-step explanation:

Calculate the percentage increase using

percent increase = $\frac{increase}{original}$ × 100%

increase = 46 - 42 = 4, hence

percent increase = $\frac{4}{42}$ × 100% ≠ 9.52%

So, y-intercept is (0,3) and x-intercept is (3/7,0)

Step-by-step explanation:

We are given:

$y=-7x+3$

We need to find y-intercept and x-intercept

Finding y-intercept

To find y-intercept we put x =0

Solving:

$y=-7x+3\\y=-7(0)+3\\y=3$

So, y-intercept is (0,3)

Finding x-intercept

To find x-intercept we put y =0

Solving:

$y=-7x+3\\0=-7x+3\\-7x=-3\\x=-3/-7\\x=3/7$

So, x-intercept is (3/7,0)

So, y-intercept is (0,3) and x-intercept is (3/7,0)

An image point has coordinates B'(7, -4). Find the coordinates of its pre-image if the translation used was (x + 4, y + 5).

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

B'(7, -4)

Let the pre-image coordinates be (x,y)

Consider x-coordinate,

x + 4 = 7

x = 3

Consider y-coordinates,

y + 5 = -4

y = -9

pre-image coordinates is (3, -9)
