Answer:
<h2>y - 6 = 2(x - 7)</h2>
Step-by-step explanation:
The point-slope of an equation of a line:
m - slope
The formula of a slope:
We have the poinys (-1, -10) and (5, 2). Substitute:
Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:
In the question we have y - 6 = ...
Therefore
<em>subtract 4 from both sides</em>
<em>use the distributive property</em>
<em>distributive</em>

Answer:
Step-by-step explanation:
A constant intervals occurs when the function is neither increasing or decreasing. In the graph, we see this occurs from 
to 
. Therefore, the interval in which the graph is constant is 
Answer:
The smaller angle = 31°
The larger angle = 149°
Step-by-step explanation:
The sum of two supplementary angles = 180 degrees
Lets x = the smaller angle
larger angle = 5x - 6
So now you have the equation:
x + 5x - 6 = 180
6x - 6 = 180
6x = 186
x = 31
The smaller angle = 31 degrees
The larger angle = 5(31) - 6 = 149 degrees
Answer:
9:7
Step-by-step explanation:
number of boys is 32 - 18 = 14
ratio will be 18:14
then 9:7
