Answer:
Step-by-step explanation:
If you want to write the equation of a line given only 2 points, you would first find the slope of both points using the slope formula, [(y2-y1)/(x2-x1)].
Then once you have your slope, you would use the point-slope formula to write your equation. (y-y1=m(x-x1)).
Answer:
1). 40ft^2
2). 32.1 cm^2
3). 28 in^2
4). 44 cm^2
5). 148.8m^2
6). 110.7 cm^2
Explanation:
You don't have to look very far in either case. Both answers are "a".
1. Checking selection "a",
265 =? 35 +20*7 = 35 +140 = 175
a (7, 265) is NOT a solution
2. Checking selection "a",
18 =? 5*4 -2 = 20 -2 = 18
a (4, 18) IS a solution
Answer:
x = 6
Step-by-step explanation:
Based on the two secants intersecting theorem, thus:
(x + 4)*4 = (3 + 5)*5
x*4 + 4*4 = (8)*5
4x + 16 = 40
4x + 16 - 16 = 40 - 16 (subtraction property of equality)
4x = 24
4x/4 = 24/4 (Division property of equality)
x = 6
0.004 kilometers... so was there a typo?
