Answer:
(4, 26)
(-6, -24)
Step-by-step explanation:
Step 1: Substitution
5x + 6 = x² + 7x - 18
Step 2: Move everything to one side
0 = x² + 2x - 24
Step 3: Factor
(x - 4)(x + 6) = 0
Step 4: Find roots
x = 4, -6
Step 5: Plug in <em>x</em> to find <em>y</em>
y = 5(4) + 6
y = 20 + 6
y = 26
y = 5(-6) + 6
y = -30 + 6
y = -24
Answer:
Option A. half the distance between point A and point K
Step-by-step explanation:
Ax=Fx
Fy=Ky
The distance between point A and point K is:
AK=Ax+Fx+Fy+Ky
Like Ax=Fx and Fy=Ky
AK=Fx+Fx+Fy+Fy
AK=2Fx+2Fy
Common factor 2:
AK=2(Fx+Fy)
The distance between point P and point Q is:
PQ=Fx+Fy
Then the distance between point P and point Q is half the distance between point A and point K:
PQ=Fx+Fy=AK/2=2(Fx+Fy)/2=Fx+Fy
Answer:
<h3>
</h3>
Step-by-step explanation:
Let's solve:
As we know that the sum of angles of traingle adds to 180°
Collect like terms

⇒
⇒
Move constant to right hand side and change it's sign
⇒
Calculate the difference
⇒
Divide both sides of the equation by 6
⇒
Calculate
⇒
Now, let's replace the value:

Hope I helped!
Best regards!!
To me to start solving thus you have to minus all the numbers by 25 which was the given number in the equation.
hope this helps.
Find 2 numbers that multiply to 6 and add to 5.
3*2 = 6
3+2 = 5
x^2 + 5x+6 = (x+3)(x+2) = 0
Set each factor equal to zero.
x+3 = 0 ----> x = -3
x+2 = 0 -----> x = -2
Answer:
There are two zeros at -2 and -3.
