Answer: (2x +3) (x-4)
2x^2 - 8x + 3x - 12
This is the answer..
Step-by-step explanation:
Answer:
t = 0.722 seconds
Step-by-step explanation:
Given in the question that an equation
h = -16t² + 6t + 4
here h is the height
t is the time
To solve this question we need to substitute height with zero because at ground level height is zero
<h3>h = 0</h3>
0 = -16t² + 6t + 4
<em>a = -16</em>
<em>b = 6</em>
<em>c = 4</em>
Formula to use
t = -b±√(b²-4ac) / 2a
Plug values in the formula
t = -6 ± √36-4(-16)(4) / 2(-16)
t = 6±2√73 / 32
t = 6+2√73 / 32 or t = 6-2√73 / 32
t = 0.722 or t = -0.347
since time can't be in negative so we reject t = -0.347
We have that
<span>y=−2x+5 --------> equation 1
3x−4y=2---------> equation 2
</span><span>substituting 1 in 2
</span>3x-4*(-2x+5)=2--------> 3x+8x-20=2--------> 11x=22-----> x=2
y=-2x+5-----> -2*2+5-----> y=1
the solution is
x=2
y=1
Answer:
Δ ABC
1) =∠3+∠4 and ∠4=∠5+∠6
∠7=∠3+∠2
So, only D) m∠7=m∠3+m∠2 is correct
