The reciprocal of any number is the other number you must multiply it by to equal one. In this case it's 9/2
Answer:
<h3> C. y + 7 = -7(x - 3)</h3>
Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
<u> </u><u>y + 7 = -7(x - 3) </u>
Answer:
3:2
Step-by-step explanation:
The ratio of boys to girls will be 12:8
But, this can be simplified, since both numbers are divisible by 4.
12/4 = 3
8/4 = 2
So, the simplified ratio of boys to girls is 3:2
