Answer:
1 mi/hr
Step-by-step explanation:
Given that:
Speed in still water, s = 5 mi/hr
Let speed of current = x
Time = distance /speed
Upstream (subtract speed of current) = 5 - x
Upstream time = 8 / 5 - x - - - (1)
Downstream (add speed of current) = 5 + x
Downstream time = 12 / 5 + x - - - (2)
Equate (1) and (2)
8 / (5 - x) = 12/ (5 + x)
8(5 + x) = 12(5-x)
40 + 8x = 60 - 12x
40 - 60 = - 12x - 8x
-20 = - 20x
x = 1
Spwed of current = 1 mi/hr

You buy a day pass to use the subway for $5. After buying the pass, you pay $2 per ride. Write an equation to describe how much money, y, you pay to ride x number of rides.
Hi there!
So here says that when I buy a day pass using the subway I pay $5 and $2 per ride.
This means that it’ll be $7 per ride.
y=7
x=1
So for every 1 ride on the subway, I have to spend $7.

Answer:
123°
Step-by-step explanation:
2z +9 = x
y = z
2Z +9 + X + z +Y = 360
Substitute for Z
2Z +9 + 2z +9 + z + z = 360
6z +18 = 360
6Z = 342
Z = 57
2(57) +9 = 123
X = 123

Answer:

Step-by-step explanation:
Answer:
Answer
5.0/5
11
Answer: Choice D. < B = < A
ie, "angle B = angle A"
The symmetric property is if y = x then x = y. The order of what is on the left or right side of the equation does not matter. It's like saying 2+3 = 5 is the same as 5 = 2+3.
This idea can be extended to congruences because congruent angles have the same measure.
So < A = < B is the same as < B = < A.

The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?
The width of the rectangle represented by the expression (x⁴ – 64)/x.
What is rectangular shape?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.
Given:
The length of a rectangle is 16 units more than its width.
Let the length is x units.
Then width = (x + 16) units.
The area of the rectangle can be expressed as
x⁴ – 64 = length x width
x⁴ – 64 = x (x + 16)
x + 16 =(x⁴ – 64)/x
Therefore, the width expression is (x⁴ – 64)/x.

Miranda graphed (y + 1)2 > 6(x - 2).
Which could Miranda use to justify that her graph is correct? Check all that apply.
Because only the y quantity is squared, the curve is a parabola.
The parabola opens right because 6 is in front of the x-quantity.
There is a strict inequality so the boundary is included in the solution set.
The shading is outside the parabola because (0,0) satisfies the inequality.
The values subtracted from x and y in the equation are the coordinates of the vertex which
O O O O
Answer:
The correct options that describe the inequality (y + 1)² > 6·(x - 2)
1) Because only the 'y' quantity is squared the curve is a parabola
2) The parabola opens right because 6 is in front of the 'x' quantity
3) The shading area is outside the parabola because (0, 0) satisfies the inequality
4) The values subtracted from 'x', and 'y' in the equation are the coordinates of the vertex
Step-by-step explanation:
The given inequality graphed by Miranda is presented as follows;
(y + 1)² > 6·(x - 2)
By simplification, we get;
Given that the inequality is of the form (y - k)² > 4·p·(x - h), we have;
The curve is a parabola as only the 'y' quantity is squared
-k = 1
∴ k = -1
4·p = 6
∴ p = 6/4 = 3/2 = 1.5
p = 1.5
-h = -2
∴ h = 2
The vertex of the parabola = (h, k) = (2, -1)
The axis of symmetry = The x-axis
p = 1.5 > 0, therefore, the parabola opens right
Therefore, the parabola opens right because 6 is in front of the 'x' quantity
There is a strict inequality therefore the boundary is not included in the solution set
When x = 0 and y = 0, we have;
(y + 1)² > 6·(x - 2)
(0 + 1)² > 6·(0 - 2)
1² > 6 × (-2)
1 > -12, which satisfies the inequality and (0, 0) is on the left and below the vertex, therefore, the shaded area is outside the parabola
The vertex of the parabola given in the form, (y - k)² > 4·p·(x - h), is (h, k), which are the values subtracted from 'x', and 'y' in the equation
Therefore, the vertex of the given parabola, (y + 1)² > 6·(x - 2) = (2, -1)

Colin invests £2900 into his bank account,
He receives 3% per year compound interest.
How much will Colin have after 4 years?
Give your answer to the nearest penny where appropriate.
Answer:
348 pounds
Step-by-step explanation:
Simple Interest = principal x rate x time
so, principal = 2900 x rate = 3/100 x time = 4 years
therefore, 2900 x 0.03 x 4 = 348 pounds
