Let's simplify step-by-step.
2(3x+5)−4(x−1)
Distribute:
=(2)(3x)+(2)(5)+(−4)(x)+(−4)(−1)
=6x+10+−4x+4
Combine Like Terms:
=6x+10+−4x+4
=(6x+−4x)+(10+4)
=2x+14
Answer:
=2x+14
1)
g+4-3g=1+g
subtracting g from both sides
4-3g=1
subtracting 4 from both sides
-3g=-3
g=1
2)
-6a+3=-3(2a-1)
extending the right side
-6a+3=-6a+3
adding 6a to both sides
3=3
which is an identity
3)
0.5b+4=2(b+2)
extending the right side
0.5b+4=2b+4
subtracting 0.5 b from both sides
4=1.5b+4
subtracting 4 from both sides
0=1.5b
b=0
4)
8-(3+b)=b-9
subtracting 8 from both sides
-(3+b)=b-17
extending the left side
-3-b=b-17
adding b to both sides
-3=2b-17
adding 17 to both sides
14=2b
b=7
The answer is 90
because increased means times so 30 + 30 = 60 + 30 = 90
The vertex form of a quadratic function: y = a(x - h)² + k
vertex (h; k)
We have: y = 7(x - 4)² + v
vertex: (4; -2)
therefore: v = -2
