Answer:

the first blank is -2 and the second blank is 140

Step-by-step explanation:

So the first blank is the slope, when you take two points from the graph you get the change in y as -20 and the change in x as 10.. to find slope, you do y/x, which is -20/10, simplified to -2. that is the first one. the second one is the y intercept which is where the y touches the y axis, which is shown on the graph as 140. good luck on your test

Answer:

x=15

Step-by-step explanation:

The equation tan(55) = 15/b can be used to find the length of line AC.what is the length of line AC round to the nearest 10th 3.
Nadusha1986 [10]

Answer:

10.5 in

Step-by-step explanation:

Given

tan(55) = \frac{15}{b}

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b

tan(55) = \frac{15}{b}

b * tan(55) = \frac{15}{b} * b

b * tan(55) =15

Divide both sides by tan(55)

\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}

b = \frac{15}{tan(55)}

Find tan(55)

b = \frac{15}{1.42814800674}

b = 10.5031130731

b = 10.5  <em>(Approximated)</em>

<em />

Length AC is 10.5
