Answer:
considering angle a to 40
b and c.....= 50 both
Part 1
All that’s being affected here is the b value in y=mx+b, so your line will just move up to have a y-intercept at (0,35) the equation will be y=4.5x+35
Part 2
Here the m value is being changed so your line will just flatten out a bit and the new equation will be y=3x+25
Hope this helps!
Let's solve your equation step-by-step.
39−2(x−8)=56
Step 1: Simplify both sides of the equation.
39−2(x−8)=56
39+(−2)(x)+(−2)(−8)=56(Distribute)
39+−2x+16=56
(−2x)+(39+16)=56(Combine Like Terms)
−2x+55=56
−2x+55=56
Step 2: Subtract 55 from both sides.
−2x+55−55=56−55
−2x=1
Step 3: Divide both sides by -2.
−2x
−2
