Answer: £ 3675.79
Step-by-step explanation:
A = P(1 + r)^t
A = final amount = x
P = initial principal balance = 3200
r = interest rate = 0.02
t = number of years elapsed = 7
x = 3200(1.02)^7
x = 3200 * 1.14868567
x = 3675.79414
x = 3675.79

Answer:
y-2x-2
Step-by-step explanation:
The way I would do this is by first using the information given and making an equation in point-slope form, before bringing it to y=mx+b.
We know that the slope is -2, and we have a point, (2,-6). The formula for equations in point slope form is [tex]y-y_{1} =m(x-x_{1} )[/tex]. So, we can insert the given information into this formula to get [tex]y+6=-2(x-2)[/tex].
Next, we distribute the slope to the the parenthesis to get [tex]y+6=-2x+4[/tex]
Then, we subtract 6 from both sides to get [tex]y=-2x-2[/tex]
Since this equation is now in the form [tex]y=mx+b[/tex], the answer is [tex]y-2x-2[/tex]

Quadrilateral abcd has vertices a(1,0) b(5,0) c (7,2) d(3,2). use slope to prove that abcd is a parallelogram.
[tex]m_{\overline{AB}}=\frac{0-0}{1-5}=0\\m_{\overline{CD}}=\frac{2-2}{3-7}=0\\\\\therefore \overline{AB} \parallel \overline{CD} \text{ because } m_{\overline{AB}}=m_{\overline{CD}}[/tex]
[tex]m_{\overline{BC}}=\frac{2-0}{7-5}=1\\m_{\overline{AD}}=\frac{2-0}{3-1}=1\\\\\therefore \overline{BC} \parallel \overline{AD} \text{ because } m_{\overline{BC}}=m_{\overline{AD}}[/tex]
As ABCD has two pairs of opposite parallel sides, ABCD is a parallelogram.
what’s a problem with no solution
When a problem has no solution you'll end up with a statement that's false. For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution.
Answer: A problem with no solution is a problem with no applicable answer or the answer is not a real number or x ∉ R

Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making x equal to 0.
≡ In other words, you must replace y with 0 to solve for x. There is no y term in this problem, so you must determine y by separating the coefficients into groups and determining each part.

Gabby and Brea went shopping at Ciara's Clothing Goods. Gabby bought 2 shirts and 1 pair of shoes, and she spent $32. Brea bought 2 shirts and 3 pairs of shoes, and she spent $48. How much does it cost per shirt, and how much does each pair of shoes cost?
The cost of one pair of shoes is $8.
The cost of one shirt is $12.
What are the linear equation that represent the question?2a + b = 32 equation 1
2a + 3b = 48 equation 2
Where:
a = cost of 1 shirt b = cost of one pair of shoesWhat is the cost of one pair of shoes?Subtract equation 1 from equation 2
2b = 16
b = 16/2
b = $8
What is the cost of one shirt?
Substitute for b in equation 1
2a + 8 = 32
2a = 32 - 8
2a = 24
a = 24 / 2
a = $12

Imagine that you are given two linear equations in slope-intercept form. You
notice that the slopes are the same, but the y-intercepts are different. How
many solutions would you expect for this system of equations?
O A. 1
OB. cannot be determined
OC. infinitely many
O D.O
Answer:
No solution.
Step-by-step explanation:
When two lines have the same slope but different y-intercepts, they are parallel. Parallel lines never intersect, and therefore there is no solution.
Dump Truck #1 is traveling east at 50 mph and is 20 miles ahead of Dump Truck #2, which is following behind it at a speed of 70 mph. How many hours will it be before they are side-by- side?
Answer:
Step-by-step explanation:
Formulas
d1 = 20 + 50*t This is dump truck #1
d2 = 70*t This is dump truck #2
d1 = d2 This is given in the problem
Solution
if d1 = d2 then you get 20+50t = 70t as your working equation.
20 + 50t = 70t Subtract 50t from both sides
20 +50t-50t = 70t-50t Combine
20 = 20t Divide both sides by 20
20/20 = 20t/20
1 = t
Answer
after 1 hour Dump Truck 2 will catch dump truck 1
The volumes of two similar solids are 512 cm3 and 2,197 cm3. If the smaller solid has a surface area of 960 cm2, find the surface area of the larger solid.
Part I: Find the similarity ratio by taking the cube root of each volume. Show your work. (2 points)
Part II: Use your answer from Part I to find the ratio of the surface areas. Show your work. (2 points)
Part III: Set up a proportion and solve to find the surface area of the larger solid. (3 points)
The similarity ratio by taking the cube root of each volume is 8/13, ratio of the surface areas is 64/169, and surface area of the larger solid is 2535 square cm.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
Part 1:
Volume of larger solid = (512) cubic cm
Volume of small solid = 2197 cubic cm
Ratio of the volumes = 512/2197
Taking cube root:
Similarity ratio = 8/13
Part 2:
Similarity ratio by taking the cube root of each volume = 8/13
Taking the square of the above ratio:
= 64/169
Part 3:
64/169 = 960/SA(larger)
SA(larger) = 2535 square cm
Thus, the similarity ratio by taking the cube root of each volume is 8/13, ratio of the surface areas is 64/169, and surface area of the larger solid is 2535 square cm.

In a shop, two customers order
Customer 1 pays £3.90 for a tea and two coffees.
Customer 2 pays £4.20 for three teas and a coffee.
How much does one cup of tea cost?
The cost of a tea cup and a cup of coffee in the shop is £0.90 and £1.50 respectively.
How to write and solve equation?let
x = cost of teay = cost of coffeex + 2y = 3.90
3x + y = 4.20
Multiply (1) by 3 to eliminate x
3x + 6y = 11.70
3x + y = 4.20
5y = 7.50
y = 7.50/5
y = 1.50
Substitute y = 1.50 into (1)
x + 2y = 3.90
x + 2(1.50) = 3.90
x + 3 = 3.90

Translation by vector <1, 3>: For any point (x, y), the new coordinates after translation are (x + 1, y + 3).
Let's apply these transformations step by step:
A (2, 2):
Reflect across y-axis: (-2, 2).
Translate by <1, 3>: (-2 + 1, 2 + 3) = (-1, 5).
So, A" is (-1, 5).
B (1, -2):
Reflect across y-axis: (-1, -2).
Translate by <1, 3>: (-1 + 1, -2 + 3) = (0, 1).
So, B" is (0, 1).
C (4, -4):
Reflect across y-axis: (-4, -4).
Translate by <1, 3>: (-4 + 1, -4 + 3) = (-3, -1).

Answer:
The way is in the steps.
Step-by-step explanation:
y = sin(x) has a period of 2π and amplitude of 1.
a) y = a * sin b(x - c) - d
y = 7/2 * sin 2/3(x - π/4) - 2
[tex]a=\frac{7}{2}[/tex][tex]b=\frac{2}{3}[/tex][tex]c = \frac{\pi }{4}[/tex][tex]d=-2[/tex]b) amplitude is affected by a = 7/2 , so the amplitude is 7/2.
The range is (-5.5 , 1.5) because looking at the graph, but also by making a table to help find the range.
c) Period = 2π/b
Period = 2π/2/3 = 3π
d) Horizontal Shift left/right is dependent on c.
c = π/4 , so Horizontal Shift to the Right by π/4
Vertical Shift up/down is dependent on d.
d = -2 , so Vertical down shift by 2.
