The equation y = -2x +12 in slope - intercept form.

Find the slope of the line that is parallel to y = -2x +3

Slope (m) = -2

Substitute and calculate ;

m = -2, x = 8 ,y = -4 into y = mx + b

-4 = -2 x 8 + b

Calculate the product :

-4 = -16 + b

Calculate the sum or difference:

-b = -12

b = 12

Again, Substitute m = -2 , b = 12 into y = mx +b :

y = -2x + 12

Rewrite the equation y = -2x + 12 in slope - intercept form:

y = -2x + 12

Hence, The equation y = -2x +12 in slope - intercept form.

For the given condition after he makes his milkshake and muffins, one and seven-twelfths cups of berries will Rasheed have left. Option D is correct.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that, Rasheed has two and three-fourths cups of berries. He uses four-sixths of a cup of berries to make a milkshake. He then uses one-half of a cup of berries.

The number of cups of berries will Rasheed has left is found by subtracting the total used amount from the total amount,

=2 3/4-(4/6+1/2)

=11/4-(4/6+1/2)

=11/4 - 7/6

=19/12

=1 7/12

Answer:

x = 12

Step-by-step explanation:

Given equation,

→ 6 + 12(x + 3) = 7x + 30 + 6x

Now the value of x will be,

→ 6 + 12(x + 3) = 7x + 30 + 6x

→ 6 + 12x + 36 = 7x + 30 + 6x

→ 12x + 42 = 13x + 30

→ 13x + 30 = 12x + 42

→ 13x - 12x = 42 - 30

→ [ x = 12 ]

Hence, the value of x is 12.

Answer:

  7.8

Step-by-step explanation:

You want the distance between P(8, 2) and Q(3, 8).

The distance between points is given by the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((3 -8)² +(8 -2)²) = √((-5)² +6²) = √61

  d ≈ 7.8

The distance between points P and Q is about 7.8 units.

__

Additional comment

You will notice that the desired distance is the length of the hypotenuse of a right triangle with legs that are 5 and 6. The Pythagorean theorem tells you that length is √(5² +6²) = √61, as above. The distance formula is based on the Pythagorean theorem.

You can find the relevant triangle leg lengths by counting grid squares on the graph. Of course, the distance formula does the same thing by subtracting coordinate values.

If the given quadrilateral is a parallelogram, then the value of x = 8  and the value of y = 9

The given quadrilateral is a parallelogram.

Then the opposite side of of the parallelogram will be equal

Then the equation will be

4x - 17 = 2x - 1

4x - 2x = -1 + 17

2x = 16

x = 16/2

Divide the terms

x = 8

Similarly given angles will be equal

3y + 5 = 5y - 13

5y - 3y = 5 + 13

2y = 18

y = 18 / 2

Divide the terms

y = 9

The critical t-distribution values converge to the critical z-distribution values as a particular family of t-distributions that t2 has 2 degrees of freedom (df) and t9 has 9 degrees of freedom.

The maximum number of logically independent values—that is, values with the freedom to change—in the data sample is referred to as the degree of freedom. When calculating degrees of freedom, one is subtracted from the total number of items in the data sample. Degrees of freedom, also known as numerical freedom of variance, are the maximum number of logically independent values that can be present in sample data. Degrees of freedom are frequently brought up when discussing various mathematical hypothesis testing techniques, like the chi-square.

Answer:draw a vertical line on the 4th line on the x axis(the horizontal one)

Step-by-step explanation:

a) the acceleration = 0.028 m/s²

b) constant speed = 10m/s

d) Distance travelled during first 10 sec = 50m

e) Distance travelled during last 10 sec = 75m

f) the total distance travelled = 350 m

Total distance travelled during first 10 sec = area of triangle

= 1/2 * 10 * 10

= 50m

Total distance travelled during next 15 sec = area of square

= 15 * 15

= 225

Total distance travelled during last 10 sec = area of triangle

= 1/2 * 10 * 15

= 75m

Total distance travelled = 50 + 225 + 75

= 350m

Velocity = Total distance / Time taken

= 350/ 35

The "average" of the "positive distances" of each point from the mean is the mean absolute deviation. There is more variability in the data the higher the MAD (the data is more spread out). The MAD aids in determining if the mean of the set serves as a reliable predictor of the values included therein.

Find the mean of the data set first, then use that value to calculate the mean absolute deviation of the data. Divide the total number of data values by the sum of the individual data values. By using the formula |data value - mean|, determine the absolute value of each data value's variance from the mean.

The average distance between each data point and the mean is known as the mean absolute deviation of a dataset. It offers us a sense of how variable a dataset is. The mean absolute deviation may be calculated as shown below.

Step 1: First, determine the mean.

Step 2: Determine the positive distances between each data point and the mean. Absolute deviations are those.

Step 3: Combine those deviations.

Step 4. Multiply the total by the number of data points.

The simplest approach to learn about mean absolute deviation is probably to follow these steps in the example below, however here is a more formal method to express the stages in a formula:
