when graphed on a coordinate plane, Bumby avenue can be represented by the equation y=-4x-7. Primrose Avenue can be represented

Lilit [14]

The complete question is;

when graphed on a coordinate plane, Bumby avenue can be represented by the equation y = -4x - 7. Primrose Avenue can be represented by the equation 8x + 2y = 17. Are these two parallel?

A) They are parallel because their slopes are the same

B) They are not parallel because their slopes are the same

C) They are parallel because their slopes are opposite reciprocals

D) They are not parallel because their slopes are opposite reciprocals

Answer:

Option D: They are not parallel because their slopes are opposite reciprocals

Step-by-step explanation:

Bumby avenue is represented by the equation y = -4x - 7 while Primrose Avenue can be represented by the equation 8x + 2y = 17.

Now, the general formula for slope intercept is;. y = mx + c.

Where m is the slope and c is the y - intercept.

This means the slope of bamby is - 4 while that of Primrose is 8.

The slopes are not the same and so options A and B are not correct.

Now, -4 is an opposite reciprocal of 8/-2.

But an opposite reciprocal means that both lines on the graph are perpendicular to each other.

Thus, option C is wrong because they are not parallel.

So correct option is D.

Write an equation of the line that passes through (2,-1) and is parallel to the line y = -3x + 8.

Anika [276]

Answer:

y = -3x +5

Step-by-step explanation:

parallel lines so slope of the lines will be equal.

m1 = m2

y = mx + b,

y = -3x + b

substituting y = -1 and x = 2

-1 = -3(2) + b

-1 = -6 + b

therefore, b = -1 + 6

b = 5

by substituting b = +5

therefore, the equation is,

y = -3x + 5

Answer:

Step-by-step explanation:

Well there is a lot more higher numbers than lower numbers, so the box would be closer to the right, and the left rectangle piece should be smaller than that of the left rectangular piece.

Falisha spent 2/5 of her money on a bag. she gave 2/3 of the remaining amount to her sister. What fraction of her money was she

alukav5142 [94]

Answer:

1/5

Step-by-step explanation:

After spending 2/5 of her money on a bag, she has 3/5 of the original amount of money left. As she gave 2/3 of the remaining amount of money to her sister, she gave 2/5 of the original amount of money to her sister (3/5 × 2/3 = 2/5). Therefore, there's only 1/5 (1 - 2/5 - 2/5 = 1/5) of the original amount of money left in her bag.

A recently published study shows that 50% of Americans adults take multivitamins regularly. Another recent study showed that 20.

Stels [109]

Answer:

The probability that a randomly selected American adult takes multivitamins regularly and works out regularly is 0.103

Step-by-step explanation:

p(Americans adults take multivitamins regularly) = 50% = 0.50

p(American adults work out regularly) = 20.6 = 0.206

p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.50* 0.206 = 0.103

Thus, p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.103
