Write the equation for the line that goes through point (12, 15) with slope = −2.

pogonyaev

Answer:

y= -2x +39

Step-by-step explanation:

y= mx+b

m is the slope which is given -2

since we don't know b we can solve the rest using the formula y-y1{ m(x-X1(

y - 15 = -2(x-12)

simplify

y-15= -2x +24

y= -2x + 39

A camera shop purchases a camera for $56.98 and sells it for $102.56. What is the percent of markup?

Amiraneli [1.4K]

Answer:

180%

Step-by-step explanation:

Set up an equation:

Variable x = percent of markup

102.56/56.98 = x/100

Cross multiply

102.56 × 100 = 56.98 × x

10,256 = 56.98x

Divide both sides by 56.98:

179.99297.... = x

Round to nearest whole number:

180 = x

Check your work:

56.98 × 180%

Convert the percentage into a decimal:

56.98 × 1.80

102.564

Round to nearest cent:

102.56

Correct!

Give triangle TRY, find TY. Round your answer to the nearest hundredth.

3241004551 [841]

The length of TY is 2.26.

Solution:

In ΔTRY, θ = 37°, Adjacent side = 3.

To find the length of TY.

Using trigonometry identity,

$$\tan\theta=\frac{{opposite}}{{Adjacent}}$

$$\tan37^\circ=\frac{{TY}}{3}$

$$3\tan37^\circ=TY$

$$3\times 0.75355=TY$

$$TY=2.26065$

TY = 2.26

Hence the length of TY is 2.26.
