Answer:
256
Step-by-step explanation:
4(7)^2 + 30(2)
196 + 60 = 256
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!
(3,4) (9,7)
to find the slope
m = (y2-y1)/(x2-x1)
= (7-4)/(9-3)
3/6
1/2
The slope is 1/2
point slope form
y-y1 = m(x-x1)
y-4 = 1/2(x-3)
distribute
y-4 = 1/2x -3/2
add 4 to each side
y = 1/2 x -3/2 + 4
y = 1/2 x -3/2 + 8/2
y = 1/2 x + 5/2
this is in slope intercept form
A. ASA similarity theorem
B. SSS similarity theorem
X = 8/15
6x - 1/5 = 3/1
6x - 1/5 = 3
6x = 3 + 1/5
6x = 15 + 1 over 5
6x = 16/5
x = 16/30
Then, you simplify.
x = 8/15
