Write (-3,7), (2,4) in standard form

Mathematics
1 answer:
tester [92]3 years ago

Answer:

y - 4 = -3/5(x - 2)

or

y - 7 = -3/5(x - (-3))

Step-by-step explanation:

In this question, we have to write an equation in standard form with the given information.

Standard form: y - y1 = m(x - x1)

First, find the slope using m = y2-y1/x2-x1:

Plug in coordinates and solve:

4 - 7/2 -(-3)

-3/2+3

m = -3/5

Now we know what our "m" value is on the equation.

You can simply use one of the coordinates and plug the values into the equation to get it in standard form. In this case, we will use the (2, 4) coordinate.

y - 4 = -3/5(x - 2) <- This is one applicable answer.

Your other answer could be y - 7 = -3/5(x - (-3))

3 more than one-half of a number is 10. What is the number?
Pani-rosa [81]

Answer:

14

Step-by-step explanation:

Let's call the number x.

\dfrac{x}{2}+3=10

Subtract 3 from both sides:

\dfrac{x}{2}=7

Multiply both sides by 2:

x=14

Hope this helps!

What is the perimeter (please explain your answer)
Alex

Answer:

<em>Answer: B. 38 mm</em>

Step-by-step explanation:

<u>The Perimeter of a Shape</u>

The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.

The figure shows a shape where all the external measures are given except the leftmost side.

This length is the sum of 3 mm + 10 mm = 13 mm.

Now calculate the perimeter:

P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm

Answer: B. 38 mm

Choose the correct description of the graph of the compound inequality: (5 points)
skad [1K]

Answer:

D

Step-by-step explanation:

Firstly,  

≤  or  ≥  means closed circle, and

<   or >  means open circle

Now, let's solve the compound inequality:

x - 1 ≤ 7

x ≤ 8

and

2x ≥ 22

x ≥ 11

This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"

Looking at the choices, D is right.
