You are going down 1 (which is minus and going in the y direction) and to left 4 is is also minus in the x direction.
(-4 , -1) Using x as the criteria only A and C have a chance. A is incorrect, because goes up one unit over the x axis. 
C <<<<< answer.

Hello!

First you have to find point h.

The you go from the center can count how many spaces over you go

Since you go 4 to the left the first number is -4

Then you count how many spaces you go up or down

Since you goes down once the second number is -1

So the answer is (-4, -1)

Hope this helps!

A line passes through the point (-2,7) and had a slope of -5
Annette [7]

Answer:

a = -1

Step-by-step explanation:

The general equation for a straight line is y = mx+c, where m is the gradient/ slope, so m = -5. The first thing we need to do is find c, which we do by plugging in the x and y values that we already know: y = 7 and x = -2

7 = -5*(-2) + c

7 = 10 + c

c = 7-10 = -3

Now, we have the general equation of y = -5x -3 and we can use this to find a.

We'll treat a as x and y will be equal to 2:

2 = -5a -3

5 = -5a (Divide both sides by 5)

-a = 1 (now by -1)

a = -1

MARKING BRAINLIST! PLEASE HELP!
Leviafan [203]

Answer:

\boxed {\boxed {\sf C. \ 4 \ inches}}

Step-by-step explanation:

Circumference is the perimeter of a circle. It can be found using the formula:

c= \pi d

However, we are given the radius.

  • The radius measures from the center to the edge of the circle.
  • The diameter measures from edge to edge through the center.
  • So, the diameter is twice the radius, or d=2r

The formula can be rewritten as:

c= \pi 2 r

We know the circumference is 25.12 inches.

25.12 \ in = \pi 2r

Let's round pi to 3.14

25.12 \ in = (3.14) 2r

We want to solve for the radius, so we must isolate it.

Divide both sides by 3.14 because the inverse of multiplication is division.

25.12 \ in / 3.14= (3.14 ) 2r  / 3.14

8 \ in = 2r

Divide both sides by 2.

8 \ in / 2 = 2r/2

4 \ in = r

The radius of the disc is <u>4 inches.</u>

A photograph of a painting measures 13 units by 17 units. If the scale factor is 1/3, what is the actual size of the painting?
Vlad1618 [11]

Answer:

39 units by 51 units

Step-by-step explanation:

The painting is a scale factor of 1/3, so each side length is 1/3 of the original.  To find the original multiply both side lengths by 3.

13x3 = 39

17 x 3 = 51
