Y=8/3x-5  my teacher want me to find the slope and y-intercept for each equation
Arte-miy333 [17]
Each of these equations follows the standard form: y = mx + b

The variable "m" is the slope, and the variable "b" is the y-intercept.

Therefore, with the equation y = 8/3x - 5, the slope ("m") would equal 8/3 and the y-intercept ("b") would equal -5

In an isosceles triangle, the longest side measures c units. The other sides of the triangle measure a units. Which equation can
Ira Lisetskai [31]

Answer:

<em>2a² = c²</em>

Step-by-step explanation:

Right triangles follow the Pythagorean Theorem, <em>a² + b² = c².</em> The hypotenuse <em>(c)</em> must be the longest of the sides. In the given triangle, both legs measure <em>a</em> units. So, <em>a = b.</em> Therefore, we have <em>a² + a² = c²</em> or <em>2a² = c²</em><em>.</em>

A sweatshirt is discounted 30%. If the discount is $9, what was the original price of the sweatshirt? Please show your work.
ArbitrLikvidat [17]

Answer:

$30

Step-by-step explanation:

Let the price of sweatshirt be $x.

Discount percentage = 30%

Discount in dollars = 30% of $x

Discount in dollars = 30/100 of $x = $ 30x/100

Given that discount in $ is 9

thus

30x/100 = 9

x = 9*100/30 = 30

Thus, the original price is $30
