Describe the lines below as parallel,
perpendicular, or neither.
2x - 5y = 25 and y= 5x+3
Answers
Answer:
Neither.
Step-by-step explanation:
First, we write 2x - 5y = 25 in slope-intercept form. That gets us y = 2/5x - 5. Now, we graph both the lines (check the image attached). Parallel means extending in the same direction, everywhere equidistant. Perpendicular means the relationship between two lines that meet at a right angle (90 degrees). As we can see in the screenshot, these lines don't fit any of these categories, so we put "neither."
The lines 2x - 5y = 25 and y = 5x + 3 are neither parallel nor perpendicular
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Equations of two lines are given, They are 2x - 5y = 25 and y = 5x + 3.
Now, Writing them in slope-intercept form,
2x - 5y = 25.
- 5y = - 2x + 25.
y = (2/5)x - 5.
And,
y = 5x + 3.
Now, We know lines parallel to each other have the same slope, and lines perpendicular to each other have a slope that is negative reciprocal of each other.
Therefore the lines y = (2/5)x - 5 and y = 5x + 3 are neither parallel nor perpendicular.

Answers
Answer:
1/6
Step-by-step explanation:
Slope is calculated as rise over run. Rise is the change in the y-axis while run is the change in the x-axis.
The two coordinates are (-2, -3) and (4, -2).
From (-2, -3), if you go up 1 unit, you would be at (-2, -2). If you go to the right 6 units, you would be at (4, -2).
So, the slope is 1/6.

Answer:
∠QPS = 101°
∠PSR = 79°
Step-by-step explanation:
The marked angles are called "same-side interior angles" or "consecutive interior angles". By either name, they are supplementary.
(2k +89) +(3k +61) = 180
5k +150 = 180 . . . . . . . . . collect terms
5k = 30 . . . . . . . . . subtract 150
k = 6 . . . . . . . divide by 5
Then the angles are ...
∠QPS = (2·6 +89)° = 101°
∠PSR = (3·6 +61)° = 79°
Answer:
∠QPS = 2 x 6 + 89 =101°
∠PSR = 3 x 6 + 61 =79°
Step-by-step explanation:
∠QPS and ∠PSR are consecutive interior angles, they are supplementary
(2k+89) + (3k+61) = 180
5k + 150 = 180
5k = 180-150 = 30
k = 6
∠QPS = 2 x 6 + 89 =101
∠PSR = 3 x 6 + 61 =79

Answers
Answer:
40 - f
Step-by-step explanation:
Total pounds of food bought= 40 pounds
Total pounds of food eaten by the dog = f pounds
Total pounds of dog food left = Total pounds of food bought - Total pounds of food eaten by the dog
= 40 - f
Expression that can be used to find the amount of dog food that is left = 40 - f
