3 0

Step-by-step explanation:

So first of all we plug in 1 into f(x) and the result of that into g(x).

f(1)=(1)^2-3(1)+5

=1-3+5

g(3)=(3)(22)-2(3)

=66-6

=60

M is the midpoint of segment GR. G has coordinates (11,-5) and M is (4,-4) Find the coordinates of R

7nadin3 [17]

Answer:

(3, -3)

Step-by-step explanation:

Given:

G = (11,-5)
M = (4,-4)
R = ?

Solution

R(x, y)

As per midpoint formula;

4 = (11 + x)/2 ⇒ x + 11 = 8 ⇒ x = 3
-4 = (-5 + y)/2 ⇒ y - 5 = -8 ⇒ y = -3
R = (3, -3)

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

$(\frac{2}{3}s + \frac{5}{6}s) = 21$
$(\frac{4}{6}s + \frac{5}{6}s) = 21$
$\frac{9}{6}s = 21$
$\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
$s = \frac{42}{3}$
$s = 14$

Determine whether The given segments have the same length. Justify your answer

Semenov [28]

We know the distance formula is

$\sqrt{ (x_{2}-x_{1})^2+ (y_{2}-y_{1})^2 }$

Here A( -4,2) and B(1,4)

So length of AB

= $\sqrt{(1-(-4))^2+(4-2)^2} =\sqrt{5^2+2^2} =\sqrt{29}$

Also C(2,1)

Length of BC

= $\sqrt{(2-1)^2+(-1-4)^2} =\sqrt{1^2+(-5)^2} =\sqrt{26}$

So we can see that length of AB is not equal to length of BC

11.

Now AB = $\sqrt{29}$

Also C(2,-1) & D(4,4)

Length of CD

= $\sqrt{(4-2)^2+(4-(-1)) ^2} =\sqrt{2^2+5^2} =\sqrt{29}$

Yes AB = CD
