Answer:
Step-by-step explanation:
Pitagora theorem is 14^2=9^2+x^2
-9^2 -9^2
so the equation is
x^2=14^2-9^2
Answer:
<u><em>-x+2y=6 and x+3y=0</em></u>
Step-by-step explanation:
Ax+By=C
y=1/2 x+ 3
y= x+6/2
2y=x+6
-x+2y=6------------1
y-2=-1/3(x+6)
3(y-2)= -(x+6)
3y-6=-x-6
3y+x=-6+6
x+3y=0------------2
Answer:
Step-by-step explanation:
<u>The first equation:</u>
<u>The second equation:</u>
<u>Convert to slope-intercept form:</u>
- x + 2y = 23 ⇒ 2y = -x + 23 ⇒ y = -1/2x + 11.5
- 2x + 3y = 39 ⇒ 3y = -2x + 39 ⇒ y = -2/3x + 13
<em>The graph is attached</em>
<u>Intersection point is (9, 7)</u>

Since you want to cancel x-terms, you're only concerned with the x-term coefficients, 5 and 4. You will want to use the opposite of one of these. It usually works well to multiply the equation with the least y-coefficient by the negative multiplier. That is ...
Multiply A by -4 and B by 5.
