<u>If she IS a member:</u>

to print 350 pictures, she will pay 0.15(350) + 10 = $62.5

THus, the amount she saves is 70 - 62.5 = $7.50

Find the slope of the line (-3,-3) (1,1)

Volgvan

Answer: The slope is m = 1

Step-by-step explanation:

-To find the slope, you need the slope formula:

$m=\frac{y2-y1}{x2-x1}$ where you have $(x1,y1)$ and $(x2,y2)$ on the equation.

-Next, you put the two points to the equation:

$m=\frac{1+3}{1+3}$

-And then you solve the equation:

$m=\frac{1+3}{1+3}$

$m=\frac{1+3}{1+3} = \frac{4}{4}=1$

$m=1$

Find the length x to the nearest whole number. A right triangle has a vertical leg of length x units, a base leg with a length o

wel

Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

The value of x is $x = 274 \ unites$

Step-by-step explanation:

From the question we are told that

The length of the vertical length is $x$

The length of the base leg is L = 330 + d units

The length of the bisecting line segment is h

The base angle is $\theta = 28^o$

The angle between d and line segment is $\theta_1 = 56^o$

For the first angle

$Tan \theta_1 = \frac{x}{d}$

=> $d = \frac{x}{Tan \theta _1}$

For the whole big triangle

$Tan \theta = \frac{x}{330 + d}$

=> $d = \frac{x}{Tan \theta } -330$

So equating the both d

$\frac{x}{Tan \theta _1} = \frac{x}{Tan \theta } -330$

Substitute values

$\frac{x}{Tan (56)} = \frac{x}{Tan (28) } -330$

$0.6745 x = 1.880x -330$

$1.20549 x = 330$

$x = 274 \ unites$
