Is x = -2 a function?
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
If you graph this function, you'll find that it looks like a vertical line, straight up and down. In a function, each x-value has to have exactly one y-value. In this function, however, any y-value you plug in gives you the same x-value: -2.
The one x-value, -2, has an infinite number of corresponding y-values, so this is definitely not a function.

The total of 3 suitcases is 127 lb. The gray suitcase weighs 11 lb more than the pink suitcase. The pink suitcase weighs 5 lb than the blue suitcase. How much does the blue suitcase weigh?
If the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb
Let the gray suitcase be represented by g
Let the pink suitcase be represented by p
Let the blue suitcase be represented by b
The gray suitcase weighs 11 lb more than the pink suitcase
g = p + 11........(1)
The pink suitcase weighs 5 lb than the blue suitcase.
p = b + 5
b = p - 5...........(2)
Total of 3 suitcases = 127 lb
p + b + g = 127............(3)
Substitute equations (1) and (2) into equation (3)
p + p - 5 + p + 11 = 127
3p + 6 = 127
3p = 127 - 6
3p = 121
p = 121/3
p = 40.3 lb
Substitute p = 40.3 into equation (2)
b = p - 5
b = 40.3 - 5
b = 35.3
The blue suitcase weigh 35.3 lb

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
The number of miles traveled by Kai's family as required in the task content is; 73 miles.
How many miles was travelled on the third day?It follows from the task content that the number of miles traveled by Kai's family on the third day is to be determined.
On this note, since the family travelled 365 miles on the first day and travelled 20% farther on the third day;
The number of miles traveled on the third day can be modelled as;
= 20% of 365
= (20 / 100) × 365
= 73 miles.
On this note, the number of miles traveled on the third day is; 73 miles.

Line R passing through point P(-2, -1) and point (3,5). Find the slope of line R.
Answer:
Slope: 6/5
Step-by-step explanation:
For this problem, you'll need to apply the slope formula Y2-Y1
X2-X1.
Let's now assign each number their position in the formula. The first set of parentheses, (-2,-1) is going to translate to (x1,y1). (3,5) will translate to (x2,y2). Now, when you put it all together, you get 5-(-1) / 3-(-2). This would give you 6/5. That would be your slope. You can then proceed to graph it. Hope this helped! :))

What is the side length of a square that has an area equal to 49 squared
inches? *
s= 7 inches
s= 6 inches
s= 5 inches
s= 8 inches
Please help me
Answer:
s= 7 inches
Step-by-step explanation:
Let the side length be x
Area of square = side × side OR [tex]side^{2}[/tex] (lets put x in place of side)
[tex]49^{2}[/tex] = x
7 = x
Side length = 7 inches
Answer:
7 inches
Step-by-step explanation:
Area of a square = 49 sq. inches
side *side = 49
side = [tex]\sqrt{49}=\sqrt{7*7} = 7 \ inches[/tex]

Answer:
Step-by-step explanation:
Thus this area is 12^2 which is 144 sq. in. The area for the circle is dependent on the radius which would be half the diameter or length of the square. The formula for the area of a circle is πr^2 so 36π is the area of the circle

y.
(5 marks)
(b) Hence, from part (a) and without using the calculator, find the value of
cos(75°) cos (15°), where x and y are special angles.
(5 marks)
Answer:
The identity is: cos(x+y)cos(x-y) = cos^2(x) - sin^2(y). Answer to part (b) is 1/4
Step-by-step explanation:
cos(x+y) = cos(x) cos(y) - sin(x)sin(y)
cos(x-y) = cos(x)cos(y) + sin(x)sin(y)
For convenience, let A = cos(x) cos(y), and B = sin(x) sin(y).
Thus,
cos(x+y) = A - B
cos(x-y) = A + B, and
cos(x+y) cos(x-y) = (A-B)(A+B) = A^2 - B^2 = cos^2(x) cos^2(y) - sin^2(x)sin^2(y) = (1 - sin^2(x))(1 - sin^2(y)) - sin^2(x) sin^2(y) =
1 - sin^2(x) - sin^2(y) + sin^2(x) sin^2(y) - sin^2(x) sin^2(y) =
1 - sin^2(x) - sin^2(y) =
cos^2(x) - sin^2(y)
(b) Let x=45, and y=30, so we have that
cos(75)cos(15) = cos(45+30) cos(45-30) =
cos^2(45) - sin^2(30) =
