Answer:
Step-by-step explanation:
hello :
x2+y2+16y−30x=0 means : (x²-30x)+(y²+16y) =0
(x²-30x+15²)-15²+(y²+16y+8²) -8²=0
(x-15)²-225+(y+8)²-64=0
(x-15)²+(y+8)²=289=17²......standard form when the center is (15,- 8)
and radius 17
This will help
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number
so...y = 1....it is a horizontal line with a 0 slope....that 1 is ur y intercept

Answer:
10 square units
Step-by-step explanation:
The triangle appears to have a base length (JL) of 4 units, and a height (JL to K) of 5 units. The area formula can be used:
A = (1/2)bh
A = (1/2)(4)(5) = 10
The area of the triangle is 10 square units.
9/2, or 4 1/2 dozen cookies. you just have to subtract
Follow the table in this order: everything on the left side of the table is the x axis value so if it is 2 find 2 on the horizontal line. Everything on the right side of the table is the y axis value so after you find where to go on the x go up from that spot to find where those two points meet. It may help if you are just starting to draw a line and find out where points meet but that will be time consuming and messy. Just remember what order you place coordinates and remember to read the labels on the graph. Hope that helped more :)
