how do you expand 2(p-j)

Answer:

A) 10.7a - 8.1b

Step-by-step explanation:

(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)

Combine like terms.

(14.2a + 0.2a - 3.7a) = 10.7a

(9.8b - 13.1b - 4.8b) = -8.1b

Answer:

Step-by-step explanation:

The vertex form of the equation of quadratic function with vertex (h, k) is:

f(x) = a(x - h)² + q

f(x) = 6(x - 10)² - 4    - given function

so:

a = 6,  h = 10,  q =  -4

Answer:

[tex]x = 70[/tex]

Step-by-step explanation:

Given

Molly: 50 out of 200

Joel: x out of 280

Required

Find x

Start by representing the giving parameters as ration

Molly= 50 : 200

Joel = x : 280

From the question, the ratios are equivalent. So,

[tex]50 : 200 = x : 280[/tex]

Convert to fractions

[tex]\frac{50}{200} = \frac{x}{280}[/tex]

Solve for x

[tex]x = \frac{50}{200} * 280[/tex]

[tex]x = \frac{1}{4} * 280[/tex]

[tex]x = \frac{280}{4}[/tex]

[tex]x = 70[/tex]

substiute the 1 for the y and the 8 for the x in the form (8=4*1+b)

subtract for so it cancels out on the right and leaves you with 4 on the left equals b on the right.

Answer:

A(n) = 4 + 8(n-1)

Step-by-step explanation:

A(n) = A(n-1) + 8

A(1) = 4

So A(2) = A(1) + 8 = 4 + 8

A(3) = A(2) + 8 = A(1) + 8 + 8 = 4 + 8 + 8

A(n) = 4 + 8(n-1)

The explicit formula for the arithmetic sequence with the given recursive formula A(n) = A(n-1) + 8 and the first term A(1) = 4 is A(n) = 8n - 4.

Given that the first term (A(1)) is 4, we can observe that each subsequent term is obtained by adding 8 to the previous term.

The general formula for an arithmetic sequence is A(n) = A(1) + (n-1)d, where A(n) represents the nth term, A(1) is the first term, n is the term number, and d is the common difference.

The first term (A(1)) is 4, and the common difference (d) is 8.

Plugging these values into the general formula, we have:

A(n) = 4 + (n-1)×8

A(n) = 4 + 8n - 8

A(n) = 8n - 4

Answer:

Step-by-step explanation:

5x + 3y = 30 - - - - - 1 x 4

3x + 4y =29 - - - - - -2 x 3

--------------------------------------------

20x +12y = 120 - - - - 3

9x + 12y = 87 - - - - - 4

The cost of cleaning each shirt is 3 dollars.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.

The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.

∴ 5x + 3y = 30...(i)

The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.

∴ 3x + 4y = 29...(ii)

Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.

So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)

Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.

The cost of cleaning each shirt is 3 dollars.

Answer: [tex]y=\frac{1}{2} x+2[/tex]

Step-by-step explanation:

The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation [tex]y= \frac{1}{2}x+2[/tex]
