Answer:

Option 1.

Step-by-step explanation:

If the inequality contains the signs < or > then the number line should have an open dot (the dot is not colored in). If the inequality contains the signs ≥ or ≤ then the number line should have a closed dot (the dot is colored in).

Since the sign is < you should pick the number line with the open dot that has an arrow facing the left side instead of the right, which is option 1.

I hope this helps you, have a nice day.

How to do a exponent with the negative base?

tatiyna

Examples :
(-2)^3 = (-2)(-2)(-2) = - 8

(-3)^4 = (-3)(-3)(-3)(-3) = 81

(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1

** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative

** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25

Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the

Alenkinab [10]

Answer:

The estimated area is $416\frac{13}{16}\ ft^{2}$

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

$9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft$

$14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft$

step 2

Find the area of one wall

$(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}$

step 3

Multiply the area of one wall by 3

$(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}$

step 4

Convert to mixed number

$\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}$

Factorize completely, x2 - 25

Furkat [3]

(x+5)(x-5) , You use difference of two squares to do this. Remember that if the sign in the equation was (+) then you wouldn’t be able to continue factoring. You can only factor equations like these if there is a subtraction sign.
