Answer:

y= - 8/3+5

Step-by-step explanation:

slope equation is equal to y=mx+B

slope = rise /run rise 8 run 3 in this case downwards

and y int which is b is 5

Answer:

The unit price is the cost per unit of an item or the cost/price for each item.

1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.

2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.

3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.

4) Store B. Because 2 is less than 3 which is less than 4.

The diagram below , not drawn to scale , shows three points R , S and F on the horizontal

Katyanochek1 [597]

The question is an illustration of right-angled triangles.

<em>The length of RF is 49.1 m</em>
<em>The length of SR is 65.5 m</em>
<em>The elevation from S to T is 30 degrees</em>

See attachment for the sketch

<u>(a) Show that RF = 49.1</u>

Considering $\triangle FTR$

We have:

$\tan(R) = \frac{FT}{RF}$ ---- tangent ratio

This gives:

$\tan(27) = \frac{25}{RF}$

Make RF the subject

$RF = \frac{25}{\tan(27)}$

$RF = 49.06$

Approximate

$RF = 49.1$

<u>(b) Calculate SR</u>

Considering $\triangle FRS$

We have:

$SR^2 = RF^2 + FS^2$ ---- Pythagoras theorem

This gives

$SR^2 = 49.1^2 + 43.3^2$

$SR^2 = 4285.7$

Take square roots

$SR = 65.5$

<u>(c) The elevation from S to T</u>

To do this, we make use of tangent ratio from $\triangle FST$

$\tan(S) = \frac{FT}{FS}$

$\tan(S) = \frac{25}{43.3}$

Take arc tan of both sides

$S = \tan^{-1}(\frac{25}{43.3})$

$S = 30^o$

Jamal hiked on two trails the 1st trail was 5 1/3 miles long and the 2nd trail was 1 3/4 time as long as the 1st trail how many

lisov135 [29]

5 1/3 + 1 3/4(5 1/3) = 16/3 + 7/4(16/3) = 16/3 + 28/3 = 44/3 or 14 2/3 <==
