I need an answer for x =
And y =

Answer:

19)   D (-8, -2)

20)  B (0, 8)

Step-by-step explanation:

-x - y = 10

-6x + 11y = 26

-x - y = 10

-x = 10 + y

x = -10 - y

-6x + 11y = 26

-6(-10 - y) + 11y = 26

60 + 6y + 11y = 26

60 + 17y = 26

17y = -34

y = -2

-x - y = 10

-x - (-2) = 10

-x + 2 = 10

-x = 8

x = -8

_______________

-x + y = 8

3x + 2y = 16

-x + y = 8

y = 8 + x

3x + 2y = 16

3x + 2(8 + x) = 16

3x + 16 + 2x = 16

5x + 16 = 16

5x = 0

x = 0

-x + y = 8

-0 + y = 8

y = 8

89 percent (calculated percentage %) of what number equals 14?

Answer: 15.730337078652.

Answer:

6y = x

Step-by-step explanation:

All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.

y = distance in meters

x = time

12y = 2x

12y/2 = 2x/2

6y = x

30y = 5x

30y/5 = 5x/5

6y = x

The equation representing the depth of the drill in meters, y, after ​x hours of drilling is y = -6x

Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.

A linear equation is in the form:

y = mx + b;

where m is the slope, b is the y intercept and y, x are variables.

Let y represent the depth of drill in meters after x hours of drilling. Hence:

Since after 2 hours, the drill is 12 meters below the surface, it can be represented by (2, 12). Also after 5 hours, the drill is 30 meters below the surface, it can be represented by (5, 30)

The equation of the line is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1) \\\\y-(-12)=\frac{-30-(-2)}{5-2}(x-2) \\\\y+12=-6(x-2)\\\\y+12=-6x+12\\\\y=-6x[/tex]

The equation representing the depth of the drill in meters, y, after ​x hours of drilling is y = -6x

Step-by-step explanation:

Answer:

The nth term of the sequence is:

[tex]a_n=\frac{-3n+3}{2}+8[/tex]

Step-by-step explanation:

Given the first 5 terms of the arithmetic sequence

8, 13/2, 5, 7/2, and 2

An arithmetic sequence has a constant difference 'd' and is defined by:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

as the common difference 'd' is:

[tex]d=a_{n+1}-a_n[/tex]

Computing the differences of all the terms

[tex]\frac{13}{2}-8=-\frac{3}{2},\:\quad \:5-\frac{13}{2}=-\frac{3}{2},\:\quad \frac{7}{2}-5=-\frac{3}{2},\:\quad \:2-\frac{7}{2}=-\frac{3}{2}[/tex]

[tex]d=-\frac{3}{2}[/tex]

The first element is:

[tex]a_1=8[/tex]

Therefore, the nth term is computed by:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=-\frac{3}{2}\left(n-1\right)+8[/tex]

[tex]a_n=\frac{-3n+3}{2}+8[/tex]

Therefore, nth term of the sequence is:

[tex]a_n=\frac{-3n+3}{2}+8[/tex]

Step-by-step explanation:

You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y

y=1

Answer: y =-1

Step-by-step explanation:y =-1

Last option is correct.

Step-by-step explanation:

The given equation is

In order to solve for y, we need to isolate y.

In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.

The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation

Answer:

b(n) = 15 - 7(n - 1)

Step-by-step explanation:

15 is the y-intercept

-7 is the slope

Answer:

[tex]a_{n}[/tex] = 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

Answer:

[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B

Step-by-step explanation:

In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,

Let us use the facts above to solve the question

∵ [tex]\frac{n}{8}[/tex] has a remainder of 5

→ Let us find the first number divided by 8 and give a reminder of 5

  that means let the quotient = 1

∵ n = (8 × 1) + 5 = 8 + 5

∴ n = 13

∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7

→ Let us find the first number divided by 8 and give a reminder of 7

  that means let the quotient = 1

∵ n + x = (8 × 1) + 7 = 8 + 7

∴ n + x = 15

∵ n = 13

∴ 13 + x = 15

→ Subtract 13 from both sides

∴ 13 -13 + x = 15 - 13

∴ x = 2

∴ [tex]\frac{n+2}{8}[/tex] has a remainder of 7
