How can we find out whether or not a point is on the line?

Answers

Answer 1

Answer:

Plug the points into an equation

Step-by-step explanation:

To find out if a point is on a line, you can plug the points back into an equation. If the values equal one another, then the point must be on a line.

Answer 2

Answer:

To determine if a point is on a line you can subsitute the x and y coordinates into the equation.. If the values equal one another, then the point must be on a line.

Step-by-step explanation:

For example if the x - 3y = 11 and the point is (2, -3) plug in

2 - 3(-3) = 11

2 + 9 = 11

11 = 11

The figure shows parallel line segments G N and F H rising slowly from left to right with segment G N above segment F H. Line segment K L falls steeply from left to right, first intersecting segment G N and then segment F H. Line segment M J rises steeply from left to right, first intersecting both segment F H and segment K L at their point of intersection and then intersecting segment G N. The 4 angles at the intersection of segments G N and K L are numbered from 1 through 4 in a clockwise direction with angle 1 above segment G N and to the left of segment K L. The 4 angles at the intersection of segments G N and J M are numbered from 5 through 8 in a clockwise direction with angle 5 above segment G N and to the left of segment J M. The 6 angles at the intersection of segments F H, K L, and J M are numbered from 9 through 14 in a clockwise direction with angle 9 above segment F H, to the right of segment K L, and to the left of segment J M.

Kayla has a puppy that weighs 5 pounds. Kayla's brother Manuel has a puppy that is 65 times the weight of Kayla's puppy. Which statement about the weight of Manuel's puppy is true?

Answers

is there a list of statements? if not i would reason that if
Kayla’s puppy’s weight=k
and we know k=5 (pounds)
and Manuel’s puppy’s weight=m
then your equation would be something like 5*65=m
which means that m=325

Answer:

-24

Step-by-step explanation:

Given expression:

3z (2y - 4)²

z = -2 and y = 3

To solve this problem, simply substitute:

3z (2y - 4)² = 3(-2){2(3) - 4}²

= -6(6-4)²

= -6 (2)²

= -6 x 4

= -24

Answer:

The answer is -24

Answer:

[tex]\boxed {x = 19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3x - 4 = 15 + 2x[/tex]

-Take [tex]2x[/tex] and subtract it from [tex]3x[/tex]:

[tex]3x - 4 - 2x = 15 + 2x - 2x[/tex]

[tex]x - 4 = 15[/tex]

-Add [tex]4[/tex] to both sides:

[tex]x - 4 + 4 = 15 + 4[/tex]

[tex]\boxed {x = 19}[/tex]

So, the value of [tex]x[/tex] is [tex]19[/tex].

Answer:

2) 162°, 72°, 108°

3) 144°, 54°, 126°

Step-by-step explanation:

1) Multiply the equation by 2sin(θ) to get an equation that looks like ...

sin(θ) = <some numerical expression>

Use your knowledge of the sines of special angles to find two angles that have this sine value. (The attached table along with the relations discussed below will get you there.)

____

2, 3) You need to review the meaning of "supplement".

It is true that ...

sin(θ) = sin(θ+360°),

but it is also true that ...

sin(θ) = sin(180°-θ) . . . . the supplement of the angle

This latter relation is the one applicable to this question.

Similarly, it is true that ...

cos(θ) = -cos(θ+180°),

but it is also true that ...

cos(θ) = -cos(180°-θ) . . . . the supplement of the angle

As above, it is this latter relation that applies to problems 2 and 3.
