If i have 35% of a phones and its now $78 how much was the phone before the discount
denpristay [2]

Step-by-step explanation:

Multiply $78 by by 65/100 to determine the original price.

78 can be put over 1.

<u>Multiply</u><u>:</u>

\frac{78}{1}  \times  \frac{65}{100}  =  \frac{5070}{100}

<u>Simplify by dividing the numerator and denominator by 100:</u>

\frac{5070 \div 100}{100 \div 100}  =  \frac{50.70}{1}

The original price was $50.70.

What is the equation of the line that passes through the points (-4,1) and (4-1)
Nitella [24]

Answer:

y=-1/4x

Step-by-step explanation:

METHOD 1: The basic slope-intercept equation is <em>y=ax+b</em>. To achieve the slope with two points, this is the equation:

m = \frac{y2-y1}{x2-x1}

All you have to do is insert points (-4, 1) and (4, -1) into their corresponding locations.

m = \frac{(-1)-1}{4-(-4)}

With this equation, you will be able to find the slope. Then you can simply graph it to connect the two dots.

METHOD 2: Simply connect the two dots with a straight line (use a ruler or something with a straight edge.) Then count how many spaces up/down and left/right. If the line goes from top to bottom from left to right, it is a negative slope (hence, the -1/4.)
