Answer:
Step-by-step explanation:
The equation 
is a <em>linear equation</em>. By definition, the independent term on this equation (that is, the number that is not being multiplied by 
) is the <em>y-intercept</em>, which is a fancy way of saying "the point where the line crosses the y-axis".
By looking at the equation, we know that our y-intercept is <em>c. </em>By looking at the graph, we can see that the y-intercept is -3. Therefore, 
and we get the complete version of our linear equation:
Now, looking at the graph we can see that the point 
lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace and 
by the values of the given point (which are 
and 
, respectively), and then solve for :
And we are done!
Answer:
x = 
Step-by-step explanation:
Given
y = 4x - 10 ( add 10 to both sides )
y + 10 = 4x ( divide both sides by 4 )
= x

Step-by-step explanation:
Answer:
85 feet
Step-by-step explanation:
P=2L+2W where L is the length and W is the width. If the length is 50 feet longer than the width, we can write the expression L=50+W. Substituting into P=2L+2W we get P=2(50+W)+2W=100+2W+2W=100+4W. Since P=300, we can say 300=100+4W. Subtracting 100 from each side we get 200=4W. Dividing each side by 4 gives 50=W. Substituting this into L=50+W gives L=50+35=85. The length is 85 feet.
Answer:
C
Step-by-step explanation:
y=1/x, the reciprocal is the same. Reciprocal would be reflected across y=x
