Answer:

y<-2x-3

Step-by-step explanation:

Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:

y=mx-3

To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.

Now it looks like this:

y=-2x-3.

Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.

Solve for the length of the hypotenuse

Answers

Answer:

5000

Step-by-step explanation:

In a right triangle ,

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

where -

c = hypotenusea & b = the other two sides of the triangle

According to the question , let the hypotenuse of the triangle be 'c' . So ,

[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]

[tex] = > c = \sqrt{9000000 + 16000000} [/tex]

[tex] = > c = \sqrt{25000000} = 5000[/tex]

Hence , c = 5000

Answer:

5000

Step-by-step explanation:

[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000

[tex]\sqrt{25000000}[/tex] = 5000

Explain the best you can because I’m struggling :)

Answers

Step-by-step explanation:

A. 3x+4/2 = 9.5

3x + 4/2 = 9.5........criss cross

3x+4= 9.5×2

3x = 19-4

3x = 15

x=5 ..........divide both sides by 3

B. 7+ 2x/3= 5.......criss cross

7+2x = 5 × 3

7 + 2x = 15

2x = 15-7

2x = 8......divide both sides by 2

x = 4

4(2a + 2) = 8(2 - 3a) whats A? please help me!!!!

Answers

Answer:

a = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

4(2a + 2) = 8(2 - 3a)

Distribute.

8a + 4 = 16 - 24a

Add 24a to each side.

32a + 4 = 16

Subtract 4 from each side.

32a = 12

Divide 32 from each side.

a = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

[tex]m(m + n) - n[/tex]

[tex]m = 5 \\ n = - 3[/tex]

Substitute m = 5 and n = - 3 in the expression.

[tex]5(5 + ( - 3)) - ( - 3) \\ 5(5 - 3) + 3 \\ 5(2) + 3 \\ 10 + 3 \\ 13[/tex]

Remind that negative multiply negative must equal positive.

Distribute 5
25+(-15)-(-3)
The minus (-3) turns into a positive so you get +3 and you add it all together and get 13 :)
