Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
Answer:
C. 2A/b
Step-by-step explanation:
A = 1/2 b*h
multiply both sides by 2
2A = 2* 1/2 bh
2A = bh
divide by b
2A/b = bh/b
2A/b=h
Answer:
y=¼x
Step-by-step explanation:
Parallel lines have the same slope
The slope of the given line is ¼,thus,
y-¼x+7=0
y=¼x-7
Now using the point-slope form y-y1=m(x-x1)
y-1=¼(x-4)
4y-4=x-4
4y=x-4+4
4y=x
y=¼x
Answer:
Y intercept is at -1
Step-by-step explanation:
the line crosses the Y-axis at -1
Answer:
A.
Amir's equation : 5.50 p + 55.99 =200
Edward's equation : 5.50 p+ 55.99 ≤ 200
B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.
Step-by-step explanation:
The budget is $200
The party room charges $55.99
The charge per person is $5.50
Letting p =number of people that can attend the party, then
A.
Equation for cost that Amir use is;
$5.50*p + $55.99 = $200
5.50 p + 55.99 =200
5.50 p = 200-55.99
5.50 p =144.01
p= 144.01/5.50 = 26 -------Amir's equation will also give the number of people that can attend the party with the budget of $200
For Edward's case
$5.50 p +$55.99 ≤ $200
5.50 p+ 55.99 ≤ 200
5.50 p ≤ 200-55.99
5.50 p ≤ 144.01
p ≤ 144.01/5.50
p ≤ 26
Edward's inequality suggests that for the budget of $200 , 26 or less people can attend the party.
B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.
