Answer:

10/6

Step-by-step explanation:

First, we plug in for the variables in the equation.

3(1/4+(1/2^2)+2(1/12) =

3(1/4+1/4)+2/12 =

3(2/4)+2/12 =

3(1/2)+1/6 =

3/2+1/6.

Next, we need to have both of these fractions to have the same denominator, which is 6.

3/2*3/3+1/6 = 9/6+1/6 = 10/6

Hope this helps

Answer is 1 1/12
3(1/4 + 1/2^2)+ (2x1/12)
3/4+1/4+2/12 (you get to this part by distributing 3 throughout the parentheses)
9/12+3/12+2/12= 1 1/12 hope this helps

For what value of k will k+9,2k-1 and 2k+7 are the consecutive terms of an A.P

Stolb23 [73]

k = 18

the common difference d of an arithmetic sequence is

d = a₂ - a₁ = a₃ - a₂ = ....

a₂ - a₁ = 2k - 1 - k - 9 = k - 10 and

a₃ - a₂ = 2k + 7 - (2k - 1) = 2k + 7 - 2k + 1 = 8, hence

k - 10 = 8 ⇒ k = 8 + 10 = 18

the 3 consecutive terms are

27, 35, 43

What is an equation of the line that passes through the points (-3, 8) and (4, 1)?

butalik [34]

Answer:

The equation of the line is:

$y=-x+5$

Step-by-step explanation:

Given the points

(-3, 8)

(4, 1)

Finding the slope between the points

$\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{1-8}{4-\left(-3\right)}$

$m=-1$

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope

substituting the values m = -1 and the point (-3, 8)

$y-y_1=m\left(x-x_1\right)$

$y-8=-1\cdot \left(x-\left(-3\right)\right)$

$y-8=-\left(x+3\right)$

Add 8 to both sides

$y-8+8=-\left(x+3\right)+8$

$y=-x+5$

Therefore, the equation of the line is:

$y=-x+5$
