Since the two are made up of congruent and unique chemicals.

I hope I have helped, can you say that this is the smartest answer please.

Answer:

A. They are similar

Step-by-step explanation:

Similar mean they have the same angle measures and proportions but they do not have to have the same side lengths. Congruent is when they have the same side lengths and angle meausres. Since one is larger than the other they are similar.

I’m pretty sure what you have to do is subtract -4.7° from 21.85° so you’d get 26.55. Because -4.7 is a negative number, you’d get a difference that’s higher

2. Simplify

x + 3 = 5

3. Subtract 3 from both sides

x + 3 - 3 = 5 - 3

What is the equation of the line that has a slope of m = 2 and passes through the point (-5, -6)?

Answers

Answer:

[tex]y=2x+4[/tex]

Step-by-step explanation:

You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)

Point-slope form:

[tex]y-y_{1}=m(x-x_{1})[/tex]

Where:

[tex]m[/tex] is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are corresponding coordinate points [tex](x,y)[/tex]

Insert the given values:

[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]

Solve for y. Expand the right sie using the distributive property:

[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]

OR

Slope-intercept form:

[tex]y=mx+b[/tex]

Where:

[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept[tex]x[/tex] and [tex]y[/tex] are corresponding coordinate points [tex](x,y)[/tex]

Insert the given values:

[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]

Simplify the multiplication:

[tex]-6=-10+b[/tex]

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

[tex]-6+10=-10+10+b\\\\4=b[/tex]

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

[tex]y=2x+4[/tex]

Answer:

  14. yes

  15. no

  16. (a) yes; (b) no; (c) -2

Step-by-step explanation:

14. Try the value and see if the result is true:

  3·2 -7 < 2   ⇒   -1 < 2 . . . . TRUE

  h = 2 is a solution

__

15. Try the value and see if the result is true:

  -12 +8 ≥ -12/4   ⇒   -4 ≥ -3 . . . . FALSE

  q = -12 is not a solution

__

16. The inequalities can be solved for the solution set.

  -2x < 10

  x > -5 . . . . . divide by -2

and

  -6 < -2x

  3 > x . . . . . divide by -2

So, the solution set is ...

  -5 < x < 3

a) x = 0 is a solution

b) x = 4 is not a solution

c) x = -2 is a solution
