Slope intercept form: y = mx + b

Where m = slope and b = y-intercept.

By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.

So now we have: y = mx + 1/2

Next, we'll find the slope. $\frac{y_2-y_1}{x_2-x_1}$

Plug the coordinates into the formula.

$\frac{3-(-2)}{4-(-4)}= \frac{5}{8}$

So our slope is 5/8 and the y-intercept is 1/2.

Option A is the answer.

a store advertises that customers can take 25% off the original price and ten take an extra 10% off. is this the same as a 35% o

maksim [4K]

Answer:

No, they are not the same.

Step-by-step explanation:

Lets say the price is 100 dollars. Lets start with the 25 and then 10 percent off. Since its 25% off we need to multiple the 100 dollar price by .75.

100*.75=75

Now that we have the 75 dollar price, we need to take off the 10%. We need to multiply the current price of 75 by .9

75*.9=67.5

The price after these 2 discounts is $67.50

Now lets do the 35% off right away. Since is 35% off we need to multiple our right of 100 by .65.

100*.65=65

The price after the 35% off is $65

So no, they are not the same.

Answer:

Step-by-step explanation:

$x,\ y-the\ numbers\\\\\text{The sum of four times a number and five times another number is -28:}\\\\4x+5y=-28\\\\\text{The sum of nine times the first number and two times the second number is 11:}\\\\9x+2y=11\\\\\text{We have the system of equations:}\\\\\left\{\begin{array}{ccc}4x+5y=-28&\text{multiply both sides by2}\\9x+2y=11&\text{multiply both sides by (-5)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}8x+10y=-56\\-45x-10y=-55\end{array}\right}\qquad\text{add both sides of the equation}$

$.\qquad-37x=-111\qquad\text{divide both sides by (-37)}\\.\qquad\qquad\boxed{x=3}\\\\\text{Put the value of x to the first equation:}\\\\4(3)+5y=-28\\12+5y=-28\qquad\text{subtrac 12 from both sides}\\5y=-40\qquad\text{divide both sides by 5}\\\boxed{y=-8}$
