What is the slope of a line parallel to the line with equation 2x+4y=8

Answers

Answer:

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

Step-by-step explanation:

To find the slope of most lines, we should rearrange the equation into the slope-intercept form or y = mx + b.

So,

2x + 4y = 8

4y = -2x + 8

[tex]y=\frac{-2x +8}{4}[/tex]

[tex]y=\frac{-2}{4}x+\frac{8}{4}[/tex]

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

The slope is the coefficient of the x term, so

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

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

2x+4y=8

4y = -2x +8

y = [tex]-\frac{2}{4}[/tex]x + [tex]\frac{8}{4}[/tex]

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

y=mx+b so the slope is m=[tex]-\frac{1}{2}[/tex].  

parallel lines have the same slope.

A bicycle helmet has a selling price of $50. The helmet is discounted 30% off the selling price. The sales tax rate is 6%. What is the total cost of the helmet?

Answers

Convert 30% to a decimal by dividing by 100 = 0.30

Multiply by the cost of the helmet, $50
50 x 0.30 = $15, the amount of the discount.

50-15 = $35, the sale price of the helmet.

For the sales tax, again, convert to a decimal by dividing by 100 = 0.06

35 x 0.06 = 2.10, the amount of sales tax

$35 + $2.10 = $37.10, total cost with tax

. A and B are vertical angles. If mA = (5x – 28) and
mB = (3x + 4)º, find the measure of each angle.

Answers

Answer:

measure of both angles is 52°

x = 16

Step-by-step explanation:

5x - 28 = 3x + 4

2x - 28 = 4

2x = 32

x = 16

Plug in 16 for 'x': 3(16) + 4 = 48 + 4 = 52°

Answer:

Both are 56°

Step-by-step explanation:

5x-28=3x+4

x=16

5(16)-28= 56°

Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0​

Answers

Answer:

a = 4 , b = -2

Step-by-step explanation:

3a + b = 10

2a + 4b = 0

(By using elimination method, eliminate one variable) - to get only one equation

(3a + b = 10 ) 4

2a + 4b = 0

12a + 4b = 40

(minus)

2a + 4b = 0

10a = 40

a = 40/10

a = 4

(substitute a into an equation to get b)

2a + 4b = 0

2(4) + 4b = 0

4b = 0 - 8

b = -8/4

b = -2

Simplify: (9a* - 5a'-1)+7a*

Answers

Answer:

The answer is -2a because first you multiple the number and eliminate redundant perenthese then last combine like terms and that how you get -2a

plese give good answer with explanation or I will report

Answers

Answer:

[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex] = 1

Step-by-step explanation:

Given[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex]To find The value of the expressionSolution

Let's rewrite the given as:

[tex]\sqrt[3]{3\sqrt{21} + 8} - \sqrt[3]{3\sqrt{21} - 8}[/tex]

Let the value is m and the expressions under 3rd roots are a and b, then we have

a = 3√21 + 8, b = 3√21 - 8m = ∛a - ∛b

Cube the both sides:

m³ = (∛a - ∛b)³m³ = a - b - 3[tex]\sqrt[3]{a^2b}[/tex] + 3[tex]\sqrt[3]{ab^2}[/tex]

Simplify in bits:

a - b = 3√21 + 8 - 3√21 + 8 = 16ab = (3√21 + 8)(3√21 - 8) = 9*21 - 64 = 125∛ab = ∛125 = 5

So the expression becomes:

m³ = 16 - 3[tex]\sqrt[3]{125a} + \sqrt[3]{125b}[/tex]m³ = 16 - 15∛a + 15∛bm³ = 16 - 15(∛a - ∛b)m³ = 16 - 15m

Solve for m:

m³ + 15m - 16 = 0m³ - 1 + 15m - 15 = 0(m - 1)(m² + m + 1) + 15(m - 1) = 0(m - 1)(m² + m + 16) = 0m - 1 = 0, m² + m + 16 = 0m = 1 is the only real root, the quadratic equation has no real roots
