2x+2a=4b solve for a

Answers

Answer:

a=2b-x

Step-by-step explanation:

Simplifying
2x + 2a = 4b

Reorder the terms:
2a + 2x = 4b

Solving
2a + 2x = 4b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x

Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x

Divide each side by '2'.
a = 2b + -1x

Simplifying
a = 2b + -1x

What is the slope of the line that passes through (-3,5) & (4,-1)

Answers

Answer:

-6/7, the first one

Answer:

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Step-by-step explanation:

Use the Slope Formula to help determine the slope of the two following points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following points to the formula:

[tex](x_{1}, y_{1}) = (-3, 5)[/tex]

[tex](x_{2}, y_{2}) = (4, -1)[/tex]

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

-Solve for the slope:

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

[tex]m = \frac{-6}{7}[/tex]

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Therefore, the slope is [tex]-\frac{6}{7}[/tex].

Answer:

d) x = 4/3

Step-by-step explanation:

Given equation,

→ -x + (3/7) = 2x - (25/7)

Now the value of x will be,

→ -x + (3/7) = 2x - (25/7)

→ -x - 2x = -(25/7) - (3/7)

→ -3x = -28/7

→ -3x = -4

→ x = -4/-3

→ [ x = 4/3 ]

Hence, the value of x is 4/3.

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

Answers

Answer:

100=25.99b+15.99d

Step-by-step explanation:

step one:

let the number of Blu-rays  be b and

DVDS be d,

step two:

given that Blu-rays cost $25.99each and

DVDS cost $15.99 each,

we can model the cost of the Blu-rays and DVDS, as

100=25.99b+15.99d

hence the expression for the number of Blu-rays and DVDS, is given as

100=25.99b+15.99d

Determine if the two fraction are equivalent, 65/4, 13/2

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]

They are not equal.

For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.

32.5/2 is not equal to 13/2

Match each complex numbers with its corresponding distance to the origin

Answers

Answer:

2. z = 1 - 2·i    →    √5

3. z = 4 + 3·i   →      54

4. z = 6 - 8·i    →     10

1. z = √5 - i      →    √6

Step-by-step explanation:

1. z = √5 - i

The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6

Therefore, z = √5 - i → √6

2) z = 1 - 2·i

The distance from the origin = √(1² + (-2)²) = √5

Therefore, z = 1 - 2·i → √5

3) z = 4 + 3·i

The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5

Therefore, z = 4 + 3·i → 5

4) z = 6 - 8·i

The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10

Therefore,  z = 6 - 8·i →  10
