Answer:
x = -2, 5.
Step-by-step explanation:
|2x - 3| = 7
2x - 3 = 7
2x = 10
x = 5 or:
2x - 3 = -7
2x = -4
x = -2.
Answer:
Use the given slope and point to substitute into the point-slope formula y−y1=m(x−x1).
Slope-intercept form:
y=3x²+4x−25
Point-slope form:
y+5=(3x+10)⋅(x−2)
Step-by-step explanation:
Boy record = 25 feet 8 inches
Girl record = 19 feet 19 inches
Boy record / Girl record = 25 feet 8 inches / 19 feet 19 inches
Change the feet into inches
1 feet = 12 inches
25 feet = 25* 12 = 300 inches + 8 inches = 308 inches
19 feet = 19 * 12= 228 inches + 19 inches = 247 inches
Boy record / Girl record = 308 inches / 247 inches
Boy record / Girl record = 1.246 inches
Boy record = 1.246 Girl record
So
it is 1.246 times greater than girls record.
Answer:
Step-by-step explanation:
2(n+3) - 4 < 6n
2n+6-4 < 6n
2n + 2 < 6n
2 < 4n
½ < n
So you want to plug in the height for h and solve for t
36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds
