Answer:
y=2x+5
Step-by-step explanation:
To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)
So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2
Slope = 2, now find b
So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5
Put it all together y = 2x + 5
Answer:
i think D
Step-by-step explanation:
13. y > 2
14. x - 13 < 9;; x < 22
15. x + 86 < 263;; at most 177 pounds
Answer:
The area of a triangle= bh/2. Substitute
12(x+6)/2 ≤ 72
12(1/2x+3) ≤ 72
6x+36 ≤ 72
6x ≤ 72-36
6x ≤ 36 Divide both sides by 6
x ≤ 6
x|x ≤6 (read: x, where x is equal or smaller than 6)
Step-by-step explanation:
(300 ft/2.92 sec)(1 mi/ 5280 ft)(3600 sec/1 hour) = {3001·3600 miles)/(2.92·5280·1 hour) = 91080000 miles/15417.6 hours = 70.05 mph
