Solve 15 ≥ -3x or 2/5 x ≥ -2.

ipn [44]

Answer:

x ≥ -5

Step-by-step explanation:

15≥-3x

switch sides

-3x≤15

Multiply both sides by -1 (reverse the inequality)

(-3x)(-1)≥15(-1)

Simplify

3x≥-15

Divide both sides by 3

3x/3≥ -15/3

Simplify

x≥ -5

Answer:

ΔXOY ≅ ΔZOW ⇒ proved down

Step-by-step explanation:

* Lets study some facts on the circle

- If two chords equidistant from the center of the circles,

then they are equal in length

* the meaning of equidistant is the perpendicular distances

from the center of the circle to the chords are equal in length

* Lets check this fact in our problem

∵ XY and WZ are two chords in circle O

∵ OT ⊥ XY

- OT is the perpendicular distance from the center to the chord XY

∵ OU ⊥ WZ

- OU is the perpendicular distance from the center to the chord WZ

∵ OT ≅ OU

- The two chords equidistant from the center of the circle

∴ The two chords are equal in length

∴ XY ≅ WZ

* Now in the two triangles XOY and ZOW , to prove that

they are congruent we must find one of these cases:

1- SSS ⇒ the 3 sides of the 1st triangle equal the corresponding

sides in the 2nd triangle

2- SAS ⇒ the two sides and the including angle between them

in the 1st triangle equal to the corresponding sides and

including angle in the 2nd triangle

3- AAS ⇒ the two angles and one side in the 1st triangle equal the

corresponding angles and side in the 2nd triangle

* Lets check we will use which case

- In the two triangles XOY and ZOW

∵ XY = ZW ⇒ proved

∵ OX = OZ ⇒ radii

∵ OY = OW ⇒ radii

* This is the first case SSS

∴ ΔXOY ≅ ΔZOW

Model the number 5.55 on the place value chart

Nady [450]

Answer:

Here's what I get

Step-by-step explanation:

Each digit in a number has a place value, based on its distance from the decimal point.

The value of a digit is the digit multiplied by its place value.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.

Numbers to the left of the decimal point increase in the order: ones, tens, hundreds, thousands, etc.

Numbers to the right of the decimal point decrease in the order: tenths, hundredths, thousandths, etc.

So, we put the digits of 5.55 on the chart according to their place value.
