Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!
Leviafan [203]

Answer:

the slope is -\frac{1}{3}

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)

So we use the formula for the slope of a line given two points:

slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\

If 75% of x is 150, what is the value of x?
vagabundo [1.1K]
I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150  or equivalently would be like  (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4

Pls help I'll give brainliest!
natali 33 [55]

Answer:

95

Step-by-step explanation:

t_n =  {n}^{2}  - 5 \\  \therefore \: t_{10} =  {10}^{2}  - 5 \\ \therefore \: t_{10} = 100  - 5 \\ \huge \red{ \boxed{\therefore \: t_{10} = 95 }}\\

10th term of the sequence is 95.
