Answer:
- exponent: -3
- coefficient: 4
Step-by-step explanation:
The coefficient of a term is its constant multiplier. The exponent is the power to which the base is raised.
The term 4·b^(-3) has an exponent of -3, a base of b and a coefficient of 4.
The exponent is -3; the coefficient is 4.
Answer:
The slope is m=2
Step-by-step explanation:
we have
This is the equation of a line in slope intercept form
where
m is the slope
b is the y-coordinate of the y-intercept
therefore
The slope m is equal to
<em>Alternative Method</em>
we know that
The formula to calculate the slope between two points is equal to
we have
and the domain {-1, 4}
For x=-1
point (-1,-7)
For x=4
point (4,3)
substitute the values in the formula of the slope
A = lw
To isolate w, you have to divide l on both sides:
w = A/l
Answer:
Option B is not a justification
Step-by-step explanation:
Option A is a justification (to get two pair of similar triangles (ABC-ACD) and (ABC-BCD))
Option C is a justification (a^2 = cy, b^2 = cx, a^2 + b^2 = cy + cx)
Option D is a justification (a^2 + b^2 = cy + cx = c(y + x) = c^2)
=> Option B is not a justification
