How do you solve this rational equation 3/4-x=x/7

Vanyuwa [196]

Answer:

x = $\frac{21}{32}$

Step-by-step explanation:

Given

$\frac{3}{4}$ - x = $\frac{x}{7}$

Multiply through by 28 ( the LCM of 4 and 7 ) to clear the fractions

21 - 28x = 4x ( subtract 4x from both sides )

21 - 32x = 0 ( subtract 21 from both sides )

- 32x = - 21 ( divide both sides by - 32 )

x = $\frac{21}{32}$

A = multiples of 5 between 14 and 26

Olenka [21]

Answer:

(A ∪ B) = {15, 17, 19, 20, 21, 23, 25}

Step-by-step explanation:

Multiples of 5:

{0, 5, 10, 15, 20, 25, ...}

So between 14 and 26:

A = {15, 20, 25}

Odd numbers between 14 and 26:

B = {15, 17, 19, 21, 23, 25}

(A ∪ B)

All numbers that are part of at least one of these sets. So

(A ∪ B) = {15, 17, 19, 20, 21, 23, 25}

Write (1,4) and(-1,1) in standard form, slope intercept form, and point slope form

gogolik [260]

Answer:

See below

Step-by-step explanation:

Standard form:

ax + by = c

Slope intercept form:

y = mx + b

Point slope form:

y - y₁ = m(x - x₁)

Use the given points and find the slope:

m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 4) / (- 1 - 1) = - 3/ - 2 = 3/2 = 1.5

Point-slope form:

y - 4 = 1.5(x - 1)

Convert this to slope-intercept form:

y - 4 = 1.5(x - 1)
y = 4 + 1.5(x - 1)
y = 4 + 1.5x - 1.5
y = 1.5x + 2.5

Convert this into standard form:

y = 1.5x + 2.5
2y = 3x + 5
3x - 2y = - 5
