He owes 200 so the first part of the equation would be the starting value of -200.

You would then multiply 25 by the number of months he has given them money and add that to the -200, this would make the -200 a smaller value every month meaning he owes his parents less money.

The answer is A. y = -200 + 25x

Answer:

The equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]

Step-by-step explanation:

Given equation of line is:

y = 2x + 7

The general form of equation in slope-intercept form is:

[tex]y=mx+b[/tex]

Here m is the slope and b is the y-intercept

Comparing the equations, we get

m = 2

Let m_1 be the slope of line parallel to given line

[tex]m_1 = m\\m_1 = 2[/tex]

The equation of line parallel to given line will be:

[tex]y=m_1x+b[/tex]

Putting the value of slope

[tex]y = 2x+b[/tex]

To find the y-intercept, putting (-1,3) in the equation

[tex]3 = 2(-1)+b\\3 = -2+b\\3+2 = b\\b = 5[/tex]

The equation is:

[tex]y = 2x+5[/tex]

Hence,

The equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]

Answer:

The third angle must be 104

Step-by-step explanation:

The last angle is found by adding 51 and 25 and the subtracting it from 180

Answer:

104°

Step-by-step explanation:

According to angle sum property of a triangle , sum of all the angles of triangle is equal to 180°.

So, let the third angle be 'x'. According to angle sum property of triangle ,

[tex]x + 25 + 51 = 180[/tex]

[tex] = > x + 76 = 180[/tex]

[tex] = > x = 180 - 76 = 104[/tex]

Answer:

B

Step-by-step explanation:

Since Greg has calculated that his least or minimum speed should.be 50 miles per hour ;

Then the line starts at 50 with the starting point shaded due to the atleast notation.

Then atleast means that, Gregg may need to travel at a higher speed than 50, so the direction of the arrow moves to the right of the number line depicting a possible increase in Gregg's speed.

Therefore, the number line which best conveys Gregg's situation is B.

Answer:A bond ladder is a portfolio of individual bonds that mature on different dates. For example, you might be able to build a ten year bond ladder with a bond maturing every year. As the bonds at the lower end of the ladder mature, the proceeds can be reinvested at the long end, in new long-term bonds.

Answer:

$1400

Step-by-step explanation:

Assuming that you would pay off the debt now and not wait any longer than to calculate how much more money you need you simply need to subtract the $1000 that you have from the total which is $2400.

$2400 - $1000 = $1400

Finally, we can see that you need an extra $1400 in order to finish paying off the debt. Unless you wait more time and the overall debt owed rises some more.

Answer:

250 hamburgers were sold on Sunday

Step-by-step explanation:

Let h be the number of hamburgers and c be the number of cheese burgers, then according to given statements, the equations will be:

[tex]h+c = 567\ \ \ \ Eqn\ 1\\c = h+67\ \ \ Eqn\ 2[/tex]

We can use the substitution method to solve the given system of equations.

Putting c= h+67 in equation 1

[tex]h+h+67 = 567\\2h+67 = 567\\2h = 567-67\\2h = 500\\\frac{2h}{2} = \frac{500}{2}\\h = 250[/tex]

Putting h=250 in equation 2

[tex]c = 250+67 = 317[/tex]

Hence,

250 hamburgers were sold on Sunday

Answer:

The value of y is 847 for x=11

Step-by-step explanation:

It is given that y is directly proportional to the square of x

This can be written mathematically as:

[tex]y \propto x^2[/tex]

Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k

[tex]y = kx^2[/tex]

Given that "When x is 5, y is 175"

[tex]175 = k (5)^2\\175 = k*25\\k = \frac{175}{25}\\k = 7[/tex]

Putting the value of k

[tex]y = 7x^2[/tex]

Now putting x = 11

[tex]y = 7(11)^2\\y = 7 * 121\\y = 847[/tex]

Hence,

The value of y is 847 for x=11

Answer:

The amount Mary would have in her account in 5 years is approximately £13,131.7

Step-by-step explanation:

The amount Mary deposits in the account, P = £10,000

The amount in interest paid by the account, r = 5.6%

The mode by which the interest is calculated = Compound interest

The number of years for which the amount (£10,000) will be kept in the account, t = 5 years

The number of times that the given interest applies per year, n = 1

The amount, "A",  Mary would have in her account in 5 years, is given by the compound interest formula as follows;

[tex]A = P \cdot \left ( 1 + \dfrac{r}{n} \right ) ^{n \cdot t}[/tex]

Where;

A = The amount accrued in the account after the given elapsed periods

P = The principal or initial balance in the account = £10,000

r = The compound interest rate = 5.6/100

n = The number of times the interest is applied in one period of time = 1

t = The sum of the duration for the interest applies = 5

Substituting the given values, we have;

[tex]A = 10,000 \times \left ( 1 + \dfrac{0.056}{1} \right ) ^{1 \times 5} = 13,131.65883211776[/tex]

Therefore, the amount Mary would have in her account in 5 years = A ≈ £13,131.7

Step-by-step explanation:

The graph for the line is attached below.

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

y = 3 - 1/2x

Now, let us find the point to plot on the graph.

So, take x= 0

y= 3

and, take x= 2

y= 3- 1

y= 2

and, take x = 6

y = 3 - 3

y= 0

Thus, the points are (0, 3), (2 , 2) and (6,0).
