Answer:

I think its neither because

Step-by-step explanation:

Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. Perpendicular lines are a bit more complicated.

Answer:

perpendicular

Step-by-step explanation:

They form a 90 degree angle because one is vertical and the other is horizontal.

Equation A simplifies to 0 = 0. It is always true.

Equation B simplifies to 1 = -1 for a ≠ 0. It is never true.

Equation C simplifies to 2a = 0. It is true only for a = 0.

Equation D simplifies to 2a = 0. It is only true for a = 0.

The equation that is true for all values of "a" is ...
A. Equation A

I need to know 35-42 please

Brilliant_brown [7]

35. an open circle means there is no equal sign, and shading to the left means less then...so inequality is : x < 6

36. a closed circle means there is an equal sign, and shading to the left means less then.... x < = 9

in short...a closed circle means there is an equal sign, an open circle means there is not. if it is shaded to the left, it is less then...if it is shaded to the right, it means it is greater then.

37. x > 4
38. x > = 4
39. x < 1
40. x < = 5
41. x > = 5
42. x < 0

What are the domain and range of this function?

Stells [14]

Answer:

Domain: $-5\leq x$

Range: $-4\leq y$

Step-by-step explanation:

Domain

The graph shows the points in which the domain is located. To find the Domain, go to the point in the x-axis (the horizontal line) and note the number where the point lies. For this question, the Domain lies in -5 and 1. Once you've found that, it's time to write it down. To do that you'll need to write the number at the most left before the one at the right. So it should be -5 less than/equal to X. Now since the point at the right is an "open-circle", x is less than the number at the most right. Not the same as a closed circle. So at the end of the process, you should have gotten -5 less than/equal to X less than 1 = $-5\leq x$ .

Range

The graph shows the points in which the range is located. To find the Range, go to the point in the y-axis (the vertical line) and note the number where the point lies. For this question, the Range lies in -4 and 7. Once you've found that, it's time to write it down. To do that you'll need to write the number at the most left before the one at the right. So it should be -4 less than/equal to X. Now since the point at the right is an "open-circle", x is less than the number at the most right. Not the same as a closed circle. So at the end of the process, you should have gotten -4 less than/equal to X less than 7 = $-4\leq y$ .

An aquarium holding African cichlids is 4 inches higher than it is wide. Its length is 30 inches, and its volume is 4200 cubic i

artcher [175]

H = w + 4 ;
V = h × w × l ;
Then, 4200 = ( w + 4 ) × w × 30 ;
4200 ÷ 30 = ( w + 4 ) × w ;
140 = ( w + 4 ) × w ;
w^2 + 4w - 140 = 0 ;
 For ax^2 + bx + c = 0, the value of x is given by: ;
In our case, a = 1 ; b = 4 ; c = - 140
Roots are - 14 and 10 ;
The correct answer is w = 10inches because w > 0 ;
Finally, h = 14 inches .
