8x=4x−32<br><br> what is the answer? please help me
Rus_ich [418]

Answer: x= -8

Step-by-step explanation:

8x-4x = -32

x(8-4) = -32

x(4) = -32

4x = -32

x = -32/4

x = -8

8(-8) = 4(-8) - 32

-64 = -32 - 32

-64 = -64

Answer:

84 Percentage increase

Step-by-step explanation:

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 40% of its value.

Percentage increase = 40% × 210

New value = 210 + Percentage increase

Calculate the New Value

New value =

210 + Percentage increase =

210 + (40% × 210) =

210 + 40% × 210 =

(1 + 40%) × 210 =

(100% + 40%) × 210 =

140% × 210 =

140 ÷ 100 × 210 =

140 × 210 ÷ 100 =

29,400 ÷ 100 =

294

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 210 =

294 - 210 =

84

Put the following equation in slope intercept form, simplifying all fractions. 12x+8y=-24
KonstantinChe [14]

The slope intercept form of the equation 12x ₊ 8y = ₋24 is

y = ₋3/2 x ₋ 3

Given the equation is 12x ₊ 8y = ₋24

we are asked to convert the given equation into slope intercept form.

Finding a line's equation requires using the slope-intercept form of a straight line. We must know both the line's slope and the point at which the line crosses the y-axis in order to use the slope-intercept formula.

12x ₊ 8y = ₋24

⇒ 12x ₊ 8y ₊ 24  = 0

we re-arrange the equation of the line to write it in the standard form

y = mx + b.

12x ₊ 8y = ₋24

8y = ₋12x ₋ 24

now divide the terms on the right side by 8.

y = ₋12x/8 ₋ 24/8

y = ₋3/2x ₋ 3

hence we get the slope intercept form as y = ₋3/2x ₋ 3, where m=s₋3/2 and b = ₋3
