Answer:
y = x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y = x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 = + c ⇒ c = 7 -
=
y = x +
← equation of line
Answer:
12 inches
First choice
Step-by-step explanation:
Solve using the formula for circumference.
C = 2πr
"C" is the circumference, which we know C = 75 in.
π = 3.14 in this problem.
"r" is the radius, which we are finding.
Substitute the numbers you know for the variables of the formula.
C = 2πr
(75in) = 2(3.14)r
Since we are finding "r", we need to isolate it. If we divide the right side by 2(3.14), it cancels out and "r" will be alone.
Put the variable on the left side for standard formatting.
Now simplify the fraction.
2 times 3.14 is 6.28
Divide the top by the bottom
r = 11.9426752 in Exact decimal answer
r ≈ 12in Rounded answer to nearest inch
