15 POINTS AND BRAINLIEST FOR FIRST ANSWER

Mathematics
1 answer:
wlad13 [49]4 years ago

Answer:

y = -(1/2)x

Step-by-step explanation:

given 8x-4y=12

arranging in slope-intercept form:

8x-4y=12

4y = 8x - 12 (divide both sides by 4)

y = 2x - 3

we can see that the slope of this line is the coefficient of x , which is 2.

The slope of a perpendicular line is the negative reciprocal of this number

m = -1/2

assembling the linear equation in point-slope form

y - y₁ = m (x - x₁)

given that the equation passes through the origin, then both x₁ and y₁=0

y - 0 = (-1/2) (x - 0)

y = (-1/2)x

y = -(1/2)x

Answer:

1 % decrease

Step-by-step explanation:

The percent of decrease time can be written as the expression \frac{200}{200}-\frac{198}{200} = \frac{2}{200}. Now, we convert the fraction into a decimal: \frac{2}{200} = \frac{1}{100} = 0.01. We can convert this decimal into a percentage: 0.01*100 = 1%.

B) f(x) = (10 - 3x)(4 - 5x)
babymother [125]

Answer:

x=10/-3, 4/5

Step-by-step explanation:

f(x) = (10 - 3x)(4 - 5x)

10-3x=0

-3x=-10

x=10/3

4 - 5x = 0

-5x = -4

x = 4/5
