9. Simplify the expression. 4x + 7y - 2 + 6y + 6y - 8x - 5 Your answer
morpeh [17]

Answer:

9. -4x+19y-7

10. 7x+20

Step-by-step explanation:

9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.

x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5

y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5

constant terms: (-2-5)-4x+19y=-4x+19y-7

10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.

Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10

Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).

x variable terms: (6x+x)+10+10=7x+10+10

constant terms: (10+10)+7x=7x+20

1. Find the missing angle for each triangle.
pantera1 [17]

Answer:

1: 42-degrees, 69-degrees, 64-degrees, 53-degrees

2: first triangle and last triangle are similar while the other two are similar to each other

Step-by-step explanation:

1: 85 + 53 + x= = 180

138 + x = 180

x = 42

2: 47 + 64 + x = 180

111 + x = 180

x = 69

3: 47 + 69 + x = 180

116 + x = 180

x = 64

4: 85 + 42 + x = 180

127 + x = 180

x = 53

STATISTICS Statisticians use the formula σ = √v to calculate a standard deviation σ, where v is the variance of a data set. Find
Leokris [45]
If <span>σ = the standard deviation and we know the deviation is 15 we can set his up like the following:

</span><span>σ = √v 
</span><span>15 = √v
Square both sides:
15^2 = \sqrt{v}^2
</span>225 = v
v = 225
