I would check my math but 4/3 = 1.3 x 18= 24 divided by 2 for radius would be 12x12=144 x pie or 3.14 would be 452.16

F(x)=2x+6
Klio2033 [76]

Answer:

Step-by-step explanation:

F(x) = 2x + 6

G(x) = - 5x - 9

product of F and G .....the product is the result of multiplication

(2x + 6)(-5x - 9) =

-10x^2 - 18x - 30x - 54 =

-10x^2 - 48x - 54 <====

Solve the equation for y. <br>y-4=1/2(x-8)
Lostsunrise [7]

All that's necessary is to add 4 to both sides of the equation. This gives

... y = 1/2(x -8) +4

If you like, you can simplify this by eliminating the parentheses and collecting terms.

... y = 1/2·x -4 +4

... y = (1/2)x

Complete the missing value in the solution to the equation.<br> y=-2x+4<br> y=-2
anygoal [31]

Answer:

X=3,y=-2

Step-by-step explanation:

This is a simultaneous equation question and we will have to solve using substitution method

So let's solve

y=-2x+4...(1)

y=-2....(2)

Let's substitute (2) into (1)

-2=-2x+4

Substrate 4 from both sides

-6=-2x

Divide both sides by-2

x=3

Substitute the value of x in (1)

y=-2(3)+4

y=-6+4

y=-2

Therefore x is 3,y is -2

Consider circle O. If AE = 7, EC = 2, and BE = 4, what is ED?
miv72 [106K]
The correct answer is 3.5

Two chords AC and BD are intersecting inside the circle. The Intersecting Chord Theorem states that when two chords intersect inside a circle, the products of their segments are equal.

Thus, for the given circle:
(AE) × (EC) = (BE) × (ED)

The lengths of the segments are
AE = 7
EC = 2
BE = 4
ED = ?

To solve for ED, we simply substitute the known values into the equation
ED =  \frac{7(2)}{4} = \frac{14}{4} = 3.5
