Answer:
x = −2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(−3x+4)+3x−3=−29
Step 1: Simplify both sides of the equation.
−2(−3x+4)+3x−3=−29
(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)
6x+−8+3x+−3=−29
(6x+3x)+(−8+−3)=−29(Combine Like Terms)
9x+−11=−29
9x−11=−29
Step 2: Add 11 to both sides.
9x−11+11=−29+11
9x=−18
Step 3: Divide both sides by 9.
9x
/9 = −18
/9
x=−2
I hope this helps!!!
Answer:
6.5 i think im not smart
Step-by-step explanation:
H(t) = Ho +Vot - gt^2/2
Vo = 19.6 m/s
Ho = 58.8 m
g = 9.8 m/s^2
H(t) = 58.8 + 19.6t -9.8t^2/2 = 58.8 + 19.6t - 4.9t^2
Maximun height is at the vertex of the parabole
To find the vertex, first find the roots.
58.8 + 19.6t - 4.9t^2 = 0
Divide by 4.9
12 + 4t - t^2 = 0
Change sign and reorder
t^2 - 4t -12 = 0
Factor
(t - 6)(t + 2) =0 ==> t = 6 and t = -2.
The vertex is in the mid point between both roots
Find H(t) for: t = [6 - 2]/2 =4/2 = 2
Find H(t) for t = 2
H(6) = 58.8 + 19.6(2) - 4.9(2)^2 = 78.4
Answer: the maximum height is 78.4 m
Answer:
0.875 = 7/8 and it is terminating
Step-by-step explanation:
Answer:
YES IT IS
Step-by-step explanation:
2-3 + 3.3
= -1 + 3.3
= -4.3
We learn that:
Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.
In this case, -4.3 can be write as -43/10
So YES it would be a rational number
Hope this helped :3
