They both are solutions.
If you plug the numbers from the ordered pairs in for x and y you will see that they equal 11.
3(3) - (-8/4) = 9 + 2 = 11
3(4) - (4/4) = 12 - 1 = 11

Answer:

AT = 8 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle

and sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AT}$ = $\frac{8}{AT}$

Multiply both sides by AT

AT × sin45° = 8, that is

AT × $\frac{1}{\sqrt{2} }$ = 8

Multiply both sides by $\sqrt{2}$

AT = 8 $\sqrt{2}$

Are the two triangles similar? If so, state the reason and the similarity statement.

BaLLatris [955]

Answer:

The triangles are not similar.

Step-by-step explanation:

Given

$\triangle IGF$ and $\triangle MNL$

See attachment for triangles

Required

Determine if both triangles are similar or not

From the attached triangles, the corresponding sides are:

IG & MN and GF & NL

Where

$IG = 12$ $MN = 14$

$GF = 16$ $NL = 18$

For both triangles to be similar, the following equivalent ratios must be equal.

$\frac{IG}{MN} = \frac{GF}{NL}$

$\frac{12}{14} = \frac{16}{18}$

$\frac{6}{7} \ne \frac{8}{9}$ -- since both ratios are not equal, then the triangles are not similar

After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand.

Answer:

$c(t) =-18t +212$

Step-by-step explanation:

Given

$(t_1,c_1) = (4,140)$

$(t_2,c_2) = (9,50)$

Required

Determine the equation

First, we calculate the slope (m)

$m = \frac{c_2 - c_1}{t_2 - t_1}$

$m = \frac{50 - 140}{9-4}$

$m = \frac{-90}{5}$

$m = -18$

The equation is then calculated as:

$c =m(t - t_1) + c_1$

$c =-18*(t - 4) + 140$

$c =-18t +72 + 140$

$c =-18t +212$

Hence, the function is:

$c(t) =-18t +212$
