Answer:
Step-by-step explanation:
IF it is a SYMMETRIC kite
CB = CD
x + 4 = 2x - 1
x - x + 4 + 1 = 2x - x - 1 + 1
5 = x
AB = AD
x + 3 = 3x - y
5 + 3 = 3(5) - y
8 = 15 - y
y = 7
Answer: 318
Step-by-step explanation:
7 to the 3rd power is 343, 343 minus 25 is 318
Answer:
y = 1/4x + 11/4
Step-by-step explanation:
Given the slope, m = 1/4, and the point, (1, 3):
We can substitute these values into the slope-intercept form, y = mx + b, in order to solve for the y-intercept.
The y-coordinate (b) of the point, (0, <em>b </em>) is the <u>y-intercept </u>of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
y = mx + b
3 = 1/4(1) + b
3 = 1/4 + b
Subtract 1/4 from both sides:
3 - 1/4 = 1/4 - 1/4 + b
11/4 = b
The y-coordinate, b, of the y-intercept is 11/4.
Therefore, the slope-intercept form is: y = 1/4x + 11/4
