The 3rd term would be -1 because T(n) is one term and 3n is another term then -1 would be the last term....im not sure if im right but ill give it a shot... ^-^

How can you use the properties of operations to evaluate<br> this expression?<br> 18 + 4(28)
nirvana33 [79]

Answer:

Well on of the properties states that unless there are parenthesis, you multiply and divide first then you add and subtract. So, first we multiply 28*4 and that leaves use with 112, now if there is no more multiplication, division, or parentheses, and there's not. We can continue all we do is add 18+112 and we get our answer of 130.

Someone pls help:( I can’t
max2010maxim [7]

Answer:

x = 8 is the answer :)

Step-by-step explanation:

Slope(m) = -2/5

slope is passing through the points: (x,1) and (3,3)

m=\frac{y_2-y_1}{x_2-x_1}

m = \frac{3-1}{3-x}

m=\frac{2}{3-x}

-\frac{2}{5} =\frac{2}{3-x}

-2(3 - x) = 2 × 5

-6 + 2x = 10

2x = 10 + 6

2x = 16

x = 8

Hopefully, this answer helped :)
