Step-by-step explanation:
Answer:
a) Graph are attached ,Red line shows the function y=3x-2 while blue line represents the function y=-5
b)(x,y)=(-1,-5)
Step-by-step explanation:
b)To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
c)Given that
y=-5
and y=3x-2
compare the right hand side of the above two equation and solve for x
3x-2=-5
or 3x=-3
or x=-1
so the solution to the given system of linear equations is =(-1,-5)
Answer:
Step-by-step explanation:
Since the triangle is isosceles and the angle between the congruent sides is x, the other two angles measure the same value.
<u>Sum of the interior angles is 180°:</u>
- x + 2*70° = 180°
- x + 140° = 180°
- x = 40°
3 angles in a triangle need to = 180 degrees
so you have 2x+3x+4x = 180
9x = 180
x = 180/9
x = 20
Answer is A
