Answer:

The answer is b the slope is negative 2 and the y-intercept is (0,3)

Step-by-step explanation:

The y-intercept is simply the point of the line that is on the y-axis. And a point can only be on the y-axis if it's x coordinate is zero. So from the table you can tell that the y-intercept is (0,3)

To find the slope you use the equation Y=Mx+b. In the equation M represents the slope, b represents the y-intercept and x and y represent the x and y of a point on the line. First plug in the y-intercept into the equation. You will get 3 =m(0) + b. Which you can use to find out that b is 3. Now your equation is 3 = Mx + 3. Now you can put in another to solve it. let's do the point (2,-1). You plug in the x and Y to get the equation -1 = m(2) +3. Subtract 3 from both sides to get -4 =m(2). Then divide 2 from both sides to get m=-2. Therefore the slope is -2

Answer:

5 hours

Step-by-step explanation:

100 - 15 = 75

75 ÷ by 15 = 5

Erin will need to work 5 more hours to pay her bill

Answer:

5 hours

Step-by-step explanation:

Erin needs $100 to pay the bill.

She has $25 in the bank.

First let's find how much money she needs more

[tex]100-25=75[/tex]

She needs $75

They said that,

she earns $15 per hour from her job.

Let the unknown hours be x.

Now let's find the hours she have to work to earn $75

 1h = $15

 x  =  $75

Use cross multiplication

[tex]75*1=15x\\\frac{75}{15} =\frac{15x}{15} \\5 h=x[/tex]

She needs to work for 5 hours in order to have the $100

Hope this helps you.

Let me know if you have any other questions :-)

Answer:

w = -11

Step-by-step explanation:

[tex]7w-3w=2(3w+11)\\4w=6w+22\\-2w=22\\w=-11[/tex]

Answer:

w = -11

Step-by-step explanation:

7w - 3w = 2(3w + 11)

Combine like terms on the left

4w = 2(3w + 11)

Divide by 2

4/2w = 2/2(3w + 11)

2w =(3w + 11)

Subtract 3w from each side

2w-3w = 3w+11-3w

-w = 11

Multiply by -1

w = -11

Answer:

  y = 3/4x +1/4

Step-by-step explanation:

Counting grid squares between the marked points, we find the point on the right is 6 units up and 8 units right of the one on the left. That means the slope of the line is ...

  m = rise/run = 6/8 = 3/4

The y-intercept can be found from the slope and one of the points. The coordinates of the point on the left are (x, y) = (-3, -2), so we have ...

  b = y -mx

  b = -2 -(3/4)(-3) = -2 +9/4 = 1/4

Then the equation of the line is ...

  y = mx +b

  y = 3/4x +1/4

Answer:

A

Step-by-step explanation:

You can eliminate B and C because the y intercept in 1, not -1. Then, you can  also eliminate D, because it is a linear equation.

Answer:  The answer is NOT Letter C. y = x2 − 1

Answer:

Step-by-step explanation:

You'd start with p, the whole amount of your pocket money, and then subtract (8/15)p, obtaining (7/15)p.  In other words, you'd be left with seven fifteenths of your beginning pocket money.

If I spend 8/15 of my pocket money in fraction, then I have left 7/15 money.

The mathematical operation is subtraction. It is employed to eliminate words or expression's objects.

Given:

I spend 8/15 of my pocket money in fraction.

Let n be the total pocket money.

Then,

left money = n - 8n/15

Left money = (15n - 8n)/15

Left money = 7n/15

Therefore, 7/15 fraction money is left.

Answer:

Step-by-step explanation:

The attached spreadsheet shows the remaining balance after each payment for each of the payment scenarios. The negative balance at the end of the payment period represents the credit that the account would have if the last payment is the full minimum payment amount. In real life, the last payment would be reduced by that value.

Card A. The 13th payment will result in a credit. It takes 13 months to pay off the credit card. The total of payments is 13×$23 -5.18 = $293.82.

Card B. The 16th payment will result in a credit. It takes 16 months to pay off the credit card. The total of payments is 16×$19 -1.75 = $302.25.

Card C. The 12th payment will result in a credit. It takes 12 months to pay off the credit card. The total of payments is 12×$26 -15.82 = $296.18.

The best deal is Card A.

__

All of the cards will be completely paid off in 5 months. The remaining balance in the 6th month is zero. The above "Answer" block shows the credit balance each card will have if payments continue to be made for 5 months.

The best deal is Card A, which will have the lowest total of payments.

_____

How the calculations are done

The balance at each step in the spreadsheet is computed as ...

  (previous balance) × (1 + rate/12) - (payment)

For example, the balance after the first payment on card A is ...

  $270 × (1 +0.1499/12) -23.00 = $273.37 -23.00 = $250.37

Each calculation is rounded to cents, as it would be on a real credit card.

Answer:

B.

Step-by-step explanation:

In mathematics, a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol, called the imaginary unit, that satisfies the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.
