Answer:
The difference between the two are the signs. -4^2 = 16 because it means -4 x -4 = 16 while (-4)^2= 16 they get the same answer but the signs and the form of operations is different
Answer:
7) A
8) 1/2
9) 5000
Step-by-step explanation:
7)
(0, 0), (4, -10)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (-10 - 0)/(4 - 0) = -10/4 = -5/2
Equation: y = -5/2 x
Answer: A
8)
(0, 0), (2, 1)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (1 - 0)/(2 - 0) = 1/2
Equation: y = 1/2 x
Answer: 1/2
9)
The value of the house increases $5000 per year, so we multiply the number of years, x, by 5000 to find the increase after x years.
Equation: y = 5000x
Answer: 5000
What is ten more than 67?
77
Answer:
$6
Step-by-step explanation:
Set up an equation:
88 = 8x + 6x + 4
Where x is the price of the shirts and pants
Subtract 4 on both sides:
88 = 8x + 6x + 4
-4 -4
84 = 8x + 6x
Combine Like Terms:
84 = 8x + 6x
84 = 14x
Divide by 14 on both sides:
84 = 14x
/14 /14
6 = x
Therefore, the price of each shirrt or pair of pants is $6.
