Answer: v = 7

Step-by-step explanation:

1. Distribute

3 (3v - 4) = 51

9v - 12 = 51

2. Add 12 to both sides

9v - 12 = 51

+ 12         + 12

3. Cancel out 12 + 12

51 + 12 = 63

9v = 63

4. Divide 9 on both sides

9v/9 = 63/9

5. Cancel out 9v/9

v = 7

The yearly compound interest rate of $640 at the end of 4 years would be; 3.07

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit of time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

[tex]CI = P\left(1 +\dfrac{R}{100}\right)^T - P[/tex]

The final amount becomes as;

[tex]A = CI + P\\A = P\left(1 +\dfrac{R}{100}\right)^T[/tex]

Given that Manuela invests $640. At the end of 4 years, Manuela has $721. then the  yearly compound interest rate will be;

[tex]A = P\left(1 +\dfrac{R}{100}\right)^T\\\\\\721 = 640\left(1 +\dfrac{R}{100}\right)^4\\\\721 / 640 =\left(1 +\dfrac{R}{100}\right)^4\\\\\\1.12 = \left(1 +\dfrac{R}{100}\right)^4\\\\\\\sqrt[4]{1.12} = \left(1 +\dfrac{R}{100}\right)\\\\\\R = 3.07[/tex]

Step-by-step explanation:

Given,

[tex]{ \tt{2y + x = - 15}} \: { \to} \: { \tt {eq}^{n} (1)}[/tex]

[tex]{ \tt{x = 3y}} \: { \to} \: { \tt{ {eq}^{n} (2)}}[/tex]

Substitute the value of eqⁿ (2) in (1) then,

[tex]{ \tt{2y}} \: + \: { \red{ \tt{3y}}} \: = - 15 [/tex]

[tex]{ \tt{5y = - 15}}[/tex]

Divide both sides by 5 then,

[tex]{ \red{ \boxed{ \tt{y = - 3}}}}[/tex]

Substitute the value of y in eqⁿ (2)

[tex]{ \red{ \boxed{ \tt{x = - 9}}}}[/tex]

Therefore, the value of (x,y) is (-9,-3)

Hence, option (d) is correct.

Answer: C

Explanation:

The range of a function is the set of all values of y that satisfy the function. On the graph, it is between the lowest value of y at the bottom and the highest value of y at the top. Looking at the graph, it extends to negative infinity at the bottom and the maximum value at the top y = 4

Thus, in interval notation,

Range = (- ∞, 4]

An equation of line with a slope of 3/4 and containing the point (0,2) is y = (3/4)x + 2

In this question, we have been given

slope (m) = 3/4

and a point (0, 2)

We need to find an equation of a line with a slope of 3/4 and containing the point (0,2)

Using the formula for the slope-point form of equation of line,

y - y1 = m(x - x1)

y - 2 = 3/4(x - 0)

y - 2 = (3/4)x

y = (3/4)x + 2

Therefore, an equation of line with a slope of 3/4 and containing the point (0,2) is y = (3/4)x + 2

This  figure has no symmetry is the correct option.

Given:

Given figure is parallelogram ,

The number of lines of symmetry of a parallelogram depends on the type of parallelogram.A non special parallelogram does not have any lines of symmetry. This includes any quadrilateral with two pairs of parallel and equal sides, except for rectangles, squares and rhombuses.

A rectangle is a parallelogram with four right angles. This property allows it to have two lines of symmetry.

A rhombus is a parallelogram with four equal sides. The number of lines of symmetry of a rhombus depends on whether it is a square or not. If it has four right angles, the rhombus is a square and thus has four lines of symmetry. If not, the rhombus only has two lines of symmetry.

Therefore this  figure has no symmetry is the correct option.

Gigi is going to buy 100 stickers.

Stickers4u - Pack of 25 stickers for £2.25

World Stationery - Pack of 10 stickers for £1.75

Buy 1 pack get 1 pack 1 free

Solution:

Cost of 1 sticker in Stickers4u = £2.25/25 stickers = £0.09

Cost of 1 sticker in World Stationery = £1.75/ 10 stickers = £0.175

Since it is mentioned, 'Buy 1 pack get 1 pack 1 free' in this shop, the total no of stickers one would get for the price would be doubled.

Hence,

Cost of 1 sticker in World Stationery would be = £1.75/ 20 stickers = £0.0875

The answer to the linear equation g(x) = 5x+50 is plotted on the graph.

Given equation:

g(x)=5x+50

The equation can also be written as y = 5x+50.

Now, we can replace the value of x for different numbers in the given equation to get the value of y to create the coordinates.

When we put x = 0 in the equation, we get y = 0 + 50 = 50.

Similarly, if we substitute the value of x as 1 in the equation, we get y = 5(1) + 50 = 55.

If we substitute the value of x as 2, y = 5(2) + 50 = 60

If we substitute the value of x as -1 and -2, we get the value of y as,

y = 5(-1) + 50 = 45 and  y = 5(-2) + 50 = 40.

These pairs of values satisfy the linear equation and are plotted on the graph given below.

Step-by-step explanation:

A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to mirror the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and form as the original, but it faces the opposite way. The opposing signs are created from the coordinates. Changes in posture during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context.

As shown in the number line, The total distance of the racing road is 70 yards.

it is given that the starting location is -35 yards behind the starting line and the ending location of the race court is 35 yards in front of the starting line.

we have to draw a Number line that has -35 and +35 so the origin of that number line is the starting point of the race court.

In the above figure if we are moving forward towards the origin we find that we are moving 35 yards in the number line, after reaching the origin of the number line move forward again 35 yards then we are at the ending location of the racing court.

So,

35 yards + 35 yards = 70 yards

The total racing area of the cars is = 70 yards.

The maximum price Charlie and Linus are wiling to pay to enter each park is 10.5 dollars.

Charlie Brown and Linus are so excited for Halloween that they have planned trips to three different parks.

They are willing to pay no more than $40 to go to all of them.

Jones’ Corn Maze has an entry fee that is $4 less than double the amount of Tomilloso’s Pumpkin Patch entrance fee.

King’s Haunted House has an entry fee that is $2 more than Tomilloso’s Pumpkin Patch.

let

x = amount of Tomilloso’s Pumpkin Patch entrance fee

Therefore,  the inequality that represent the situation is as follows;

Jones’ Corn Maze an entry fee = 2x - 4

King’s Haunted House entry fee = 2 + x

Therefore,

2x - 4 + 2 + x + x ≤ 40

4x - 2 ≤ 40

add 2 to both sides of the inequality

4x - 2 + 2 ≤ 40 + 2

4x ≤ 42

divide both sides of the inequality by 4

4x  / 4 ≤ 42 / 4

x ≤ 10.5

The highest price of house that Holly can afford is £343350.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Given that, Holly can afford to spend, including Land Transaction Tax, is £327000.

Here, the tax rate is 5% because that is above £250000 and below £400000.

Let x be the highest price of house that Holly can afford.

x= 327000+5% of 327000

x= 327000+5/100 ×327000

x= 327000+0.05×327000

The exponent of a number shows how many times the number is multiplied by itself.
