This is a situation known as AAA (angle, angle, angle)
Knowing three angles only determines the triangle up to similarity.
If we don't know at least one length, we're not going to be able to find any lengths.
We know the solutions of x because we know the 2 x intercepts which are (0,0) and (5,0).
Answer: yes, 34/6 converted into a mixed number is 5 2/3
Hope this helps..... Stay safe and have a Merry Christmas!!!!!!!!!!!! :D
I just wish i could get at least 25 friends by Christmas because my account got deleted yesterday..
Answer:
<em>B) -7x + 7y = -49</em>
Step-by-step explanation:
This is a y=x plot/line shifted by 7 units.
This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.
Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
