Answer:

The lines are parallel, with the same slope of 5.

Step-by-step explanation:

Remember that if slopes are the same, then the lines are parallel. If the slopes are opposite reciprocals, they are perpendicular. If they are neither of those cases, then they would be neither.

1) Since y = 5x + 1 is already in slope-intercept format (y = mx + b, in which m represents the slope) we know that 5 is the slope of that equation.

2) To find the slope of -5x + y = 6, let's just convert it to the slope-intercept format by isolating y on the left side like so:

$-5x + y = 6 \\y = 5x + 6$

(All you need to do is move -5x to the right side of the equation.) So, by looking at y = 5x + 6, we can do the same thing we did from step 1 and find that the slope is 5.

3) Since both of the equations' slopes are 5, they share the same slope - therefore, they are parallel.

Hope this helps! Please do not hesitate to ask any questions.

-1.5, 1 and 2
1.5, -1 and 2
1.5, 1 and -2

Answer 29.

The product of two nonzero integers will be less than or equal to both of the integers if they are multiplied by number itself and one or by number itself and one with negative sign.

Answer 30.

The sign of the product of three integers with the same sign will be positive or negative. If odd number of same sign is multiplied, the product will be of that sign.

(+) (+) (+) = (+)

(-) (-) (-) = (-)

{362 – [63 + (48 ÷ 2) x 2]} + 3(9 +4)

Julli [10]

Answer:

Step-by-step explanation:

<u>Solving with one operation at each step:</u>

{362 – [63 + (48 ÷ 2) x 2]} + 3(9 +4) =
{362 – [63 + 24 x 2]} + 3(9 +4) =
[362 – (63 + 48)] + 3(9 +4) =
(362 – 111) + 3(9 +4) =
251 + 3(13) =
251 + 39 =

Number of trees that are grew more than 3 feet = 10 + 35 = 45

Number of trees that grew more than 3 feet and is more than 50 yards away = 35

P(3 feet and more than 50 yards) = 35/45 = 7/9

$\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

We can solve this equation in one step only, and this is the step:-

Subtract 7 from both sides

p=12-7

p=5
