Answer:
2 Miles per hour
Step-by-step explanation:
velocity (speed) formula is distance/time.
In this case, 6/3=2
Answer: y=-(3x-2)= -3x+2
The intercept with y is 2
The intercept with x is 2/3
Answer:
See below.
Step-by-step explanation:
The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.
Also they omitted the other possibility that the expression in the vertical lines could be negative.
We also have the inequality
- 4x + 1 < - 3
-4x < -4
x > 1.
Answer:
The jeweler made 9 necklaces.
The jeweler made 8 bracelets.
Step-by-step explanation:
x = number of bracelets
y = number of necklaces
17 = x + y
238 = 5x + 22y
Make one of the coefficients, x, the same.
17 = x + y
Multiply this equation by 5.
85 = 5x + 5y
Subtract the equations to get rid of x.
(238 = 5x + 22y) - (85 = 5x + 5y)
(5x - 5x) + (22y - 5y) = 238 - 85
22y - 5y = 238 - 85
17y = 153
y = 153/17 = 9
The jeweler made 9 necklaces. Substitute this back into one of the equations to find x.
17 = x + y
17 = x + 9
17 - 9 = x
x = 8
238 = 5x + 22y
238 = 5x + 22(9)
238 = 5x + 198
238 - 198 = 5x
40 = 5x
x = 40/5
x = 8
The jeweler made 8 bracelets.
2193 x 10(little 37) over 79
or
≈2.77595 x 10(little 38)
