Answer:

D

Step-by-step explanation:

Given

(x + 2)² + 5(x + 2) - 6 = 0

Using the substitution u = x + 2 , then the equation can be expressed as

u² + 5u - 6 = 0 → D

If C=(a,b,x,y) and D=(m,n,o,p) then c union d is
Ilya [14]

Step-by-step explanation:

here,

C={ a,b,x,y}

D ={ m,n,o,p}

now,

C union D ={a,b,x,y} union {m,n,o,p}

= {a,b,x,y,m,n,o,p}

therefore C union D ={ a,b,x,y,m,n,o,p}

Option D: 140° is the right answer

Step-by-step explanation:

In the given figure, a traversal is intersecting two parallel lines.

When two parallel lines are intersected by a traversal 8 angles are formed.

Corresponding angles:

Corresponding angles have same relative position when two parallel lines are intersected by a traversal So in the given figure the corresponding angles are:

m∠1 and m∠5

m∠2 and m∠6

When two parallel lines are intersected by a traversal, the corresponding angles are equal

So,

m∠1 = m∠5

m∠5 = 140°

Hence,

Option D: 140° is the right answer

Keywords: Traversal, parallel lines

PLEASE HELP The y-intercept of the equation y = 12x - 8 is 8. True False
stira [4]

Answer: False!

This equation is in slope - intercept form, where y = mx + b. B is the y - intercept and m is the slope. They got the location of the y - intercept right, but they forgot to add the negative. It's actually -8.

Hope this helps!

What is the likelihood the next crayon randomly selected will be yellow
tamaranim1 [39]
So.... there are 10 crayons and 8 are yellow.  

This means that 8/10 of the crayons are yellow.  

So the chance of picking a yellow one is 80%.  


To get this, you need to do 8/10 and make it over 100, which is 80/100.  Then, you turn this number into a percent by just dropping the 100 and adding a % to 80 (it's this easy if the bottom denominator is 100) 

The work should look something like this;

8:10
8/10
80/100
80%

So, there is an 80% chance that the crayon you pick will be yellow.  Any questions?
