Answer:

Step-by-step explanation:

If bank A keeps adding on 1,000 and bank B is only doubling by 2 then A is much greater than B.

The account that has more money after one week is account A.

The account that has more money after two weeks is account A

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Account A:

Balance = $5000

Each week increase = $1000

Amount after one week.

= 5000 + 1000

= 6000

Amount after 2 weeks.

= 6000 + 1000

= 7000

Account B:

Balance = $1

Each week's increase = doubles the amount

Amount after 1 week.

= $2

Amount after 2 weeks.

= $4

Thus,

Account A has more money after one week.

Account A has more money after two weeks.

Answer:

1 percent, or 20 marbles

Step-by-step explanation:

add all the other percentages and it sums up to 99%. and the other one percent of the marbles is 20.

Answer:

20 marbles

Step-by-step explanation:

61.5 + 27.5 + 10 = 99

this means 1% are neither red, white or blue

1% of 2000 is 20

Step-by-step explanation:

if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.

the inverse function simply tries to calculate the original x it of the original y.

and then, to make it a formal function, we rename x to y and y to x.

y = 3x³

x³ = y/3

[tex]x = \sqrt[3]{ \frac{y}{3} } [/tex]

=> as "regular" function

[tex]y = {f}^{ - 1} (x)= \sqrt[3]{ \frac{x}{3} } [/tex]

x= 0,1

y= -2,2

Answer: 8p + -4p = 2p + 6

Combine like terms: 8p + -4p = 4p

4p = 2p + 6

Reorder the terms:

4p = 6 + 2p

Solving

4p = 6 + 2p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-2p' to each side of the equation.

4p + -2p = 6 + 2p + -2p

Combine like terms: 4p + -2p = 2p

2p = 6 + 2p + -2p

Combine like terms: 2p + -2p = 0

2p = 6 + 0

2p = 6

Divide each side by '2'.

p = 3

Simplifying

p = 3

Prerequisites :-

1) The product of slope of two perpendicular lines is-1 .

2) The slope of two parallel lines is same .

Given two lines to us are ,

This line is in slope intercept form which is [tex] y = mx + c [/tex] . Comparing to which we get ,

Again , the second line given to us is ,

Convert it into slope intercept form , we have ,

[tex]\implies 3( x + 3y ) = 18 [/tex]

Divide both sides by 3 ,

[tex]\implies x + 3y = 6 [/tex]

Solve for y ,

[tex]\implies y = \dfrac{-x}{3} + 2 [/tex]

On comparing to the slope intercept form ,

And the product both the slopes is ,

[tex]\implies m_1 \times m_2 = \dfrac{-1}{3}\times 3 =\boxed{\red{-1}}[/tex]

Hence the given two lines are perpendicular .

Answer: EQUATIONS OF HORIZONTAL AND VERTICAL LINES. In general, linear equation is a function whose graph is a straight line and it is typically written as. y = mx + b, where m is the slope and b is the y-intercept. An horizontal lines goes left and right and its equation is in the form of. y = b,

Step-by-step explanation:

The slope of 3x + 4y = 12 is m = -3/4

To get the slope, you must use the slope-intercept form y = mx + b to find the slope.

The x-intercept of 3x + 4y = 12 are located at: (4,0)

To find the x-intercept, you must substitute in 0 for y and solve for x.

The y-intercept of 3x + 4y = 12 are located at: (0,3)

To find the y-intercept, you must substitute in 0 for x and solve for y.

Please view the graph attached below that has the slope and intercepts of 3x + 4y = 12 sketched.

Answer:

181 pounds

Step-by-step explanation:

You have already got the equation and solution which is great! The next step is simply a matter of replacing "x" with "7", because you know x=7.

After doing this, you will be left with the equation 160+3*7=195-2*7. We will look at the first part of the equation first. Using the rules of BIDMAS, you can calculate 3*7=21 and then 160+21=181. 181 is your final answer.

You can check that this is right by calculating the second part of the equation, and once done you should be left with 181. Again, using BIDMAS, you need to do 2*7=14 then 195-14=181. Now we know that everything is correct.
