The missing value for x=-1 is y=6

By substituting the known values in the equation gives the unknown value.

Given equation is y=2-4x

To find y when x=-1

Substitute x=-1 in given equation,

we get y=2-4(-1)

y=6

Hence, the value of y when x=-1 is 6

Answer:

C) (8,12)

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\MP= (\frac{5+11}{2} )(\frac{9+15}{2} )\\MP= (\frac{16}{2} )(\frac{24}{2} )\\MP= (8,12)[/tex]

Initial velocity = 63m/s

Final velocity = 75m/s

Time taken = 4.2

We have to find acceleration of car[tex].[/tex]

_________________________________

◈ Acceleration is defined as the rate of change of speed.

It is a vector quantity having both magnitude as well as direction.

SI unit : m/s²

⇒ a = (v - u) / t

⇒ a = (75 - 63) / 4.2

⇒ a = 12/4.2

The speed of a car traveling on a straight road increases from 63 m/s to 75 m/s in 4.2 seconds. What was the car's acceleration?

final answer = 6cm

Answer:

CB = 1.4 cm

Step-by-step explanation:

Given is a right angled triangle.

[tex] {x}^{2} + {1.4}^{2} = {2}^{2} \\ {x}^{2} + 1.96= 4 \\ {x}^{2} = 4 - 1.96 \\ {x}^{2} = 2.04 \\ x = \sqrt{2.04} \\ x = 1.42828569 \\ x \approx 1.4[/tex]

The common difference between successive terms in this arithmetic sequence is 6.

Option D is the correct answer.

It is a sequence where the difference between each consecutive term is the same.

We have,

The common difference between successive terms in the sequence 2, 8, 14, 20, 26, ... is 6.

To see why, notice that each term in the sequence is obtained by adding 6 to the previous term.

For example, to get from 2 to 8, we add 6. To get from 8 to 14, we add another 6.

This pattern continues for each successive term in the sequence.

Thus,

The common difference between successive terms in this arithmetic sequence is 6.

Answer:

23 percent

Step-by-step explanation:

The percentage of females who are freshmen or sophomores will be 50%.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.

The frequency table shows the distribution of 1,200 students at a high school.

The frequency table is given below.

Then the percentage of females who are freshmen or sophomores will be

P = (134 + 162) / 592 x 100

P = 296 / 592 x 100

P = 0.5 x 100

P = 50%

Thus, the correct option is B.

Answer:

Surface Area =237.5

Answer:237.5

Step-by-step explanation:

First coupon:

89 - 50 = $39 (discount price)

Second coupon:

50% = 0.5

89 * 0.5 = 44.5

89 - 44.5 = $44.5 (discount price)

39 < 44.5

Therefore, the better option is using the $50 off one item.

[tex]\boxed {\tt A= 14 \ ft^2}[/tex]

Step-by-step explanation:

The area of a triangle can be found using the following formula.

[tex]A=\frac{1}{2} bh[/tex]

where [tex]b[/tex] is the base and [tex]h[/tex] is the height.

In this triangle, the base is 7 feet and the height is 4 feet.

[tex]b= 7 \ ft\\h= 4 \ ft[/tex]

Substitute the values into the formula.

[tex]A=\frac{1}{2} bh[/tex]

[tex]A=\frac{1}{2} (7\ ft)(4 ft)[/tex]

Multiply 7 ft and 4 ft.

[tex]A=\frac{1}{2} (28 \ ft^2)[/tex]

Multiply 28 square feet by 1/2 or divide 28 square feet by 2.

[tex]A= 14 \ ft^2[/tex]

The area of the triangle is 14 square feet.

Answer:

3ny

Step-by-step explanation:

For this problem, the price of a widget is represented by 'n' amount of dollars.  Additionally, the store was stocked with 4y widgets.

To find the total cost of the widgets sold, we will use the information that at the end of the day, the store only had y widgets remaining.

From here we can say the following to represent the total cost of the widgets sold:

cost = n * (4y - y)

cost = n * (3y)

cost = n3y

You can rewrite this cost to be 3ny as in the answer choice.

Cheers.
