Answer:

From left to right, -3/2, -4/5, -3/10, 1/2, 7/8, 4/3

Step-by-step explanation

So what we're trying to do here is to order the numbers from greatest to least.

Let's start off with the negative numbers.

-3/10, -4/5, -3/2.

Now what we want to do is give them all a common denominator to figure out which one is the least of that group.

-3/10,-8/10,-15/10.

Now on to the positive numbers.

1/2, 4/3, 7/8

Turn the denominator into 24.

12/24, 32/24, 21/24

Then put them all in order.

Answer:

-3/2, -4/5, -3/10, 1/2, 7/8, 4/3

What is inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality'.

Given that, a band is selling candy bars for a fundraiser, Sierra sold some candy bars, Breanna sold twice as many candy bars as Sierra and together Sierra and Breanna sold no less than 45 candy bars

Which two equations relate the measure of ∠4, to the measures of ∠1, ∠2, and/or ∠3.
A. m∠4 = m∠1 + m∠2
B. m∠4 = m∠2 + m∠3
C. m∠4 = 180° − m∠3
D. m∠4 = 180° − (m∠3 + m∠2)

Answers

A. m4 = m1 + m2
C. m4 = 180° - m3

A. m∠4 = m∠1 + m∠2

C. m∠4 = 180° − m∠3

In any triangle ABC the measure of the exterior angle is equal to the sum of the interior angle opposite to it.The sum of exterior angle and interior angle is equal to 180 degrees.

So we can write

m∠4 = m∠1 + m∠2

And m∠4 + m∠3= 180°

m∠4 = 180° − m∠3

Therefore, the correct equations are :

A. m∠4 = m∠1 + m∠2

C. m∠4 = 180° − m∠3

Answer:

y = -4x + 8   its a negative function but it is linear

Step-by-step explanation:

can you plz markit brainliest

Slope (m) = ΔYΔX= -4

1= -4

θ = arctan( ΔY ) + 360°

ΔX= 284.03624346793°

ΔX = 2 – 0 = 2

ΔY = 0 – 8 = -8

Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353
