If the inequality symbol, is an x or equal to symbol, the dot will be closed.

Pick the number and put it at the center and then label the rest on the number line.

If the variable is on the left side of the inequality, you can use whichever way the "arrow" (the inequality symbol) is pointing to shade.


If it is w ≥ 0, then you would graph on the number line 0 and make the dot filled in, and graph in the direction going right (>)


Inequality symbols

> greater than

< less than


≥ greater than or equal to

≤ less than or equal to

Answer:

3. closed circle on 0 and shading to the right ( w is any # greater than 0)

4. closed circle on -4 and shading to the left ( b is any # less than -4)

5. open circle on 1.5 and shading to left ( a is any # less than 1.5)

Ex.

0 < 1.5, or -2 <0

Just use any # on where its shaded

The legs of the isosceles triangle each measure 14 inches. calculate the length of the hypotenuse
Evgen [1.6K]

Answer:

I'm guessing you are talking about an isosceles RIGHT triangle.

In such a triangle, the length of the hypotenuse equals the length of either leg times the square root of 2.

hypotenuse = 14 * square root of 2 =

14 * 1.4142135623731  = 19.79898987322330

or rounding that equals 19.80 inches

What is the smallest of 3 consecutive positive integers if the product of the smaller two integers is 5 less than 5 times the la
Irina18 [472]
So consecutive intergers are 1 away from each other so
the numbers are
x,x+1,x+2
if the product (multily) of 2 smaeller is 5 less than 5 times largest so
(x times (x+1)) is 5 less than 5 times (x+2)
(x times (x+1))=-5+5(x+2)
pemdas
distribute using distributiver property
a(b+c)=ab+ac so
x times (x+1)=x^2+x
5(x+2)=5x+10
we have
x^2+x=-5+5x+10
add like terms
x^2+x=5x+5
subtract (5x+5) from both sides
x^2-4x-5=0
factor by find what 2 numbers add to -4 and multply to get -5
numbers are 1 and -5
so we do
(x+1)(x-5)=0
sete each to zero
x+1=0
x-5=0

x+1=0
sbtract 1
x=-1
we want positie so thisis wrong answer

x-5=0
add 5
x=5
subsitute
x,x+1,x+2
5,5+1,5+2
5,6,7


smalles is 5

The figure shown is created by joining two rectangles.
Vesnalui [34]
First cut off for now the rectangle at the top. Ok so now do 75X15 = 1,125. Now we know that's the area if we cut off the top. Now do just the top 10X25=250. Now add 1,125+250= 1,375. is the area
