Answer:

The first term of the sequence is -8.95 with a common difference of 2.1.

The sequence is:

-8.95, -6.85, -4.75, -2.65...

Step-by-step explanation:

We are given that the sum of the first ten terms of a linear sequence is 5, and the sum of the next ten terms is 215.

And we want to find the sequence.

Recall that the sum of an A.P. is given by:

S = k / 2 ( a + xk)

Where a is the first term, k is the number of terms, and x_k is the last term.

We can represent our term values with the direct formula:

Xn = a + d (n-1)

Where the first term, x₁ = a.

The sum of the first ten terms is 5. Hence, S = 5, k = 10, a = x₁ and x_k = x₁₀:

(5) = 10/2 (a+xk)

5 = 5(a+(a+9d))

2a + 9d = 1

The sum of the next ten terms (that is, from x₁₁ to x₂₀) is 215. Hence, S = 215 when k = 10, a = x₁₁, and x_k = x₂₀:

(215) = (10)/2 (a + xk)

215 = 5((a+d(11-1))+(a+d(20-1)))

2a + 29d = 43

This yields a system of equations:

[tex]\left \{ {{2a+9d=1} \atop {2a+29d=43}} \right.[/tex]

Solve:

(2a + 9d) + (-2a - 29d) = (1) + (-43)

-20d = -42

d = 2.1

Consequently:

a = 1/2(1-9d)

= 1/2(1-9(2.1))

= -8.95

In conclusion, the first term of the sequence is -8.95 with a common difference of 2.1.

The sequence is:

-8.95, -6.85, -4.75, -2.65...  

Answer: 4y-1

Step-by-step explanation:

Simplifying 3xy = 12 Solving 3xy = 12 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '3y'. x = 4y-1 Simplifying x = 4y-1

Answer: 13

Step-by-step explanation: 6.5 x 2=13

Answer:

x=13

Step-by-step explanation:

13/2=6.5

Given that

In ∆ ABD , AB = BD------(1)

=> Angle B = Angle D

Since the angles opposite to equal sides are equal.

=> Angle A = Angle D

and

BC bisects Angle B

=> Angle BCA = Angle CDB ----(2)

And

BC = BC (Reflexive Property) -----(3)

From Eqⁿ(1),(2)&(3) we have

BA = BD

< ABC = BCD

BC = BC ( Common Side)

Therefore, ∆ ABC =~ ∆ DBC

by SAS property

Hence, proved.

Step-by-step explanation:

20 pounds each day per horse

so 2 weeks is 14 days

which means 20x14

then there are 15 horse

so 15(20x14)

Answer:

I'm going to use the following as an example.

[tex]2x + 4y = 8[/tex]

To find the y-intercept, set x equal to 0 then solve for y.

[tex]2(0) + 4y = 8[/tex]

two times zero is zero, so we have the following equation.

[tex]4y = 8[/tex]

Solve for y

[tex] \frac{4y}{4} = \frac{8}{4} \\ y = 2[/tex]

Your first point you will graph is (0, 2).

Now solve for the x intercept. To do this, set y = 0.

[tex]2x + 4(0) = 8[/tex]

4(0) = 0, so you can remove it, and solve for x.

[tex]2x = 8[/tex]

[tex] \frac{2x}{2} = \frac{8}{2} \\ x = 4[/tex]

Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.

Answer:

Weeks is the independent variable and height is the dependent variable.

Step-by-step explanation:

The height of the plant depends on the weeks the plant has been growing. So the height is the dependent variable. Because the number of weeks doesn't depend on anything, the number of weeks is an independent variable.

Answer:

[tex]y= 11x+35[/tex]

Step-by-step explanation:

Let's find the slope first. It took hopt 11 months (from 5 to 16) to grow 77 trees. It means that each month he grew [tex]\frac{77}{11} = 7[/tex] trees.

At this point you can use the point-slope form and re-write the equation or, let's think about it. It's a direct proportion. If at month 5 she has 90 trees, one month earlier she had 11 less. two month earlier, 22 less. 5 month earlier, or at x = 0 (ie, our intercept!) she had 55 less trees, or 90-55 = 35 trees

The equation is then [tex]y= 11x+35[/tex]
