You will have to use a^2+b^2=c^2 Place the 152 where c is and place 132 in place of a. Then solve for B. I hope this helps.

Can you help meee get this ?

Answer: y=4/5x-2 or y=4/5x+(-2)

Step-by-step explanation:

The formula for slope-intercept form is y=mx+b.

To find the slope, we can use the formula $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ and plugging in the points given.

$m=\frac{6-2}{10-5} =\frac{4}{5}$

We know our slope is 4/5. We can plug this into our slope-intercept form and then plug in a point to find b, y-intercept.

$y=\frac{4}{5} x+b$

$2=\frac{4}{5}(5)+b$

$2=4+b$

$b=-2$

We know the y-intercept is -2.

THe final equation is y=4/5x-2 or y=4/5x+(-2).

Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. Wh

Answer:

$10d + 40r \leq 450$

Step-by-step explanation:

Given

$Savings = 450$

$Dana\ Cooks, d = 10$

$Restaurant, r = 40$

Required

Represent this as an inequality

When Dana cooks;

$Cost\ per\ meal = 10$

$Cost\ per\ d\ meals = d * 10$

$Cost\ per\ d\ meals = 10d$

At Restaurant

$Cost\ per\ meal = 40$

$Cost\ per\ r\ meals = 40 * r$

$Cost\ per\ r\ meals = 40 r$

Add these two results:

$Result = 10d + 40r$

<em>To represent as an inequality, the above result must be less than or equal to Dana's total savings</em>

i.e.

$10d + 40r \leq 450$
