Answer:
X-intercept is 5
Step-by-step explanation:
find the x-intercept let y=0
x+2(0)=5
x+0=5
x=5
Answer:
the answer is option B
Step-by-step explanation:
To find dy/dx the equation here is
first multipled by derivative of second + second multipled by derivative of first
y = x*sinx
dy/dx = x * derivative of sinx + sinx * derivative of x
derivative of x with respect to x is 1
derivative of sinx with respect to x is cosx
therefore
dy/dx = x * cosx + sinx * 1
= x * cosx + sinx
Answer:
x=±√−9
No real solutions.
Step-by-step explanation:
Step 1: Add 3x^2 to both sides.
27+3x2=−3x2+3x2
3x2+27=0
Step 2: Subtract 27 from both sides.
3x2+27−27=0−27
3x2=−27
Step 3: Divide both sides by 3.
3x2
/3
=
−27
/3
x2=−9
Step 4: Take square root.
x=±√−9
Answer:
A
Step-by-step explanation:
He needs to collect at least 120 so if c is what he must still collect
64 +c must be greater than or equal to 120
