Answer:

x = 0.5

Step-by-step explanation:

2(2x-1)=3

2(2x)+1=3

-1 -1

2(2x)=2 2x2=4

4x=2

4÷4 Cancels out the 4 in X

2÷4=0.5

Therefore

x = 0.5

Suppose cos(O) = 12/13, Quadrant I. Find sin(O).<br> A:13/12<br> B:5/13<br> C:13/5<br> D:5/12

noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

Hope this helps

Classify the relationship represented in each scatter plot as linear, quadratic or exponential.

vesna_86 [32]

Answer:

1. quadratic

2. quadratic

3. linear

4. quadratic

Step-by-step explanation:

In the picture attached, the scatter plots are shown.

The differences between these correlations are:

linear : makes a straight line

quadratic: makes a ∩ or ∪

exponential: rises or falls quickly in one direction

In plot 1, 2 and 4, we can see that y-values decrease at first and then they increase. This is a feature of quadratic correlation

In plot 3, we can see that y-values increase uniformly as x-values increase.This is a feature of linear correlation

A number line going from negative 1 to positive 1 in increments of 1. There are 5 equal spaces between each number. Select all t

miv72 [106K]

Answer:

–1 is less than Negative StartFraction 4 Over 5 EndFraction

Step-by-step explanation:

Number line from - 1 to + 1 in Increment of 1 ; with 5 equal spaces between each number ;

–0.3 is less than One-fifth

0 is greater than –0.5

Negative three-fifths is equal to –0.6

Number line :

-1 to 0 to 1

-1, - 0.8, - 0.6, - 0.4, - 0.2, 0, 0.2, 0.4, 0.6, 0.8, 1

–1 is less than Negative StartFraction 4 Over 5 EndFraction : - 1 < - 0.8 (true)

–0.3 is less than One-fifth : - 0.3 < 0.2 (true)

0.6 is greater than 1 ( false)

0 is greater than –0.5 (true)

Negative three-fifths is equal to –0.6; - 0.6 = - 0.6 ( true)
