Answer:
y = 4x -7
Step-by-step explanation:
Rearranging the slope-intercept for equation, we can find the intercept:
y = mx +b
y -mx = b . . . . . subtract mx
We know the slope of the parallel line is the same as that of the given line (m=4), so we only need to find 'b'.
b = 9 -4(4) = -7
The desired equation is ...
y = mx +b
y = 4x -7
Answer: 13
Step-by-step explanation:
Slope = (-3 - 1) / (4 -4) = -4
Answer:
h = A/b
Step-by-step explanation:
A = bh Divide b from both sides of the equation
A/b = bh/b On the right side, the b in the numberator and denominator cancel out.
h = A/b
Answer:
the ladder reaches up to 9.75 ft. high
Step-by-step explanation:
a^2+b^2=c^2
plug in the numbers
a^2+49=144
then subtract 49 from 144
a^2=95
then sq 95
a=9.75
