  D.  2x -y = 2

Step-by-step explanation:

You want to know the standard-form equation of the line through points (-1, 4) and (2, 2) as shown on the graph.

The graph shows the x-intercept of the line is a=1, and the y-intercept of the line is b=-2. This means the intercept form of the equation is ...

  x/a +y/b = 1

  x/1 +y/(-2) = 1

Multiplying this equation by 2 gives ...

  2x -y = 2 . . . . the standard form equation for the line

__

Additional comment

The standard form equation can also be developed from the coordinates of points on the line:

  (y2 -y1)x -(x2 -x1)y = (y2 -y1)x1 -(x2 -x1)y1

  (2 -(-4))x -(2 -(-1))y = (2 -(-4))(-1) -(2 -(-1))(-4)

  6x -3y = -6 +12

Dividing by 3 gives the standard form equation ...

  2x -y = 2

Answer:

y = - 17

Step-by-step explanation:

6y + x = - 59 → (1)

x = - 2y + 9 → (2)

substitute x = - 2y + 9 into (1)

6y - 2y + 9 = - 59

4y + 9 = - 59 ( subtract 9 from both sides )

4y = - 68 ( divide both sides by 4 )

y = - 17

Answer:

Armando lost 65 coins each level.

Step-by-step explanation:

Given information,

→ Armando lost 975 coins playing his favorite video game.

→ He lost the same number of coins in each of the 15 levels he played.

Forming the equation,

→ 15x = 975

Now required value of x will be,

→ 15x = 975

→ x = 975/15

→ [ x = 65 ]

Hence, he lost 65 coins each level.

1) In figure 4, the area of the square os 16cubes. The shaded part is 7cubes, being one less than 4^2 or 4*4.  The formula is n+n-1. This can be put in for 5 too. 5+5-1=9.

2) Using the formula, 50+50-1=99. Therefor, the shaded squares in the 50th figure would be 99.

Complete sentence:

1) The formula for the number of shaded squares in the Nth figure is n+n-1.

2) There would be 99 shaded squares in the 50th figure.

explanation: Knowing that the area of a square is length*width, in this case because the figures are squares, the length and the width are both the same number. From this, we can tell that for figure 45, the length is 45 and so this the width. The one square in the corner is both the length and the width so this is why we take 1 away or -1.

By using the formula for amount of money in a compound interest, it can be calculated that

Amount received after 7 years is $13675.08

What is a compound interest?

If the interest on a certain principal at a certain rate over a certain period of time increases exponentially rather than linearly, then the interest earned is called compound interest.

If p is the principal, r is the rate and n is the time in years, then

amount = [tex]p(1+\frac{r}{100})^n[/tex]

Difference between amount and principal gives the compound interest.

Principal = $8800

Rate = 6.5 %

Time = 7 years

Amount received = [tex]8800(1 + \frac{6.5}{100})^7[/tex]

Answer:

I believe the answer is C

Step-by-step explanation:

The daily amount in grams of the recommended carbohydrates is 2587.15 grams

The amount of daily recommended carbohydrate is solved by dividing the quantity of carbohydrate in the protein bar by the percentage contained in the bar

The problem deals with percentage and 7% is written as

7%

= 7 percent

= 7 / 100

= 0.07

The factor 0.07 of the daily recommended amount of carbohydrates gives 20 grams of carbohydrate

let the daily recommended amount of carbohydrates be x

0.07 * x = 200

0.07x = 200

x = 200 / 0.07

x = 2587.15 grams

Answer:

Step-by-step explanation:

Perpendicuar lines have slopes that are opposite reciprocals: 6 ==> -1/6

y=mx+b

y=-x/6 + b ==> plug in slope -1/6 into slope equation

1 = -6/6 + b ==> plug in x and y values into slope equation

1 = -1 + b

1 + 1 = -1 + 1 + b

b = 2 ==> solve for b

y = -x/6 + 2 ==> plug in the value of b into the equation

y - 1 = -x/6 + 2 - 1

y - 1 = -x/6 + 1

y - 1 = -(x/6-1) ==> answer: 1

-1.5 is the difference in the sequence

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms are the same.

The difference is usually called the common difference. For example, the sequence 3, 6, 9, 12 have a common difference of 3 i.e. 6-3 = 3 or 9-6 = 3

Given: the sequence 4.5,3,1.5,0

The difference = 3 - 4.5 = -1.5 or 1.5-3 = -1.5

Note: You can pick any two consecutive terms to get the difference

Therefore, the difference in the sequence is -1.5

The probability that the sample proportion will differ from the population proportion by more than 3% is 0.8948

The requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.

In this case, the sample proportion:

= ✓[p(1 - p)/n]

= ✓(0.13 × 0.87)/329

= 0.01854.

The probability will be:

P(-0.03 / 0.01854) < z < (0.03 / 0.01854)

P(-1.62 < z < 1.62)

Answer: A

Step-by-step explanation:

By assuming that the initial height of the rocket is the ground, we will get the height equation:

H(t) = -16*t^2 + 235*t

The height equation for any object near the surface of the heart that is not being subject to any other forces than the gravitational one is:

H(t) = -16*t^2 + v*t + h

Where:

t represents the time in seconds.

the first coefficient -16 is half of the gravitational acceleration in feet over squared seconds.

v is the initial velocity, which in this case is 235 ft/s

h is the initial height, in this case we assume is zero (the rocket is launched from the ground)

Replacing all that in the height equation, we will get:

H(t) = -16*t^2 + 235*t

Answer:

y = ±√100-x

Step-by-step explanation:

To work out the inverse of this function :

We solve for x then swap x and y :

Solving for x :

y = 100 - x²

Add x² to both sides :

x² + y = 100

Subtract y from both sides :

x² = 100-y

Square root both sides :

x = ±√100-y

Now we have solved for x. Now swap x and y :

y = ±√100-x

This is our final answer and is the first option.

Step-by-step explanation:

The base of the separated triangle is (x+5) - (2x - 4) = x + 5 - 2x + 4 = 9 - x

So, area of the separated triangle would be:-

1/2 * b* h

or, 1/2 * (9-x)* (x+3)

or, (6x + 27 - x² )/2

Total area of trapezium = (6x + 27 - x²)/2 + (2x-4)(x + 3)

or, 60 = (6x + 27 - x²)/2 + 2x² + 2x - 12

or, 60 = (6x + 27 - x² + 4x² + 4x - 24)/2

or, 120 = 10x + 3x² + 3

or, 0 = 3x² + 10x + 3 - 120

According to the remainder theorem, if we subtract 68 from the given trinomial it should be divisible by x - 4. In other words, one of zero's will be x = 4.

The distribution that is needed for the problem that we have here is the t distribution.

With its bell-shaped structure and heavier tails, the t-distribution, commonly referred to as the Student's t-distribution, is a kind of probability distribution that resembles the normal distribution.

When there are insufficient samples or unknown variances, it is used to estimate population parameters. T-distributions have broader tails than normal distributions because they are more likely to contain extreme values.

We have tn-1
