Write the equation in slope-intercept form of the line that has a slope of -2 and y-intercept of 2.
bixtya [17]

Answer:

y= -2x +2

Step-by-step explanation:

<u>Slope-intercept form:</u>

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -2, m= -2.

Substitute m= -2 into the equation:

y= -2x +c

Given that the y-intercept is 2, c= 2.

Substitute c=2 into the equation:

y= -2x +2

if a one bedroom apartment that rents for $450 in Detroit rents for 250% of that price in manhattan, what is the rent in Manhatt
lesya [120]

Answer:

$1125

Step-by-step explanation:

To find percentage of something, we always take the percentage, convert it to decimal by dividing by 100, and then multiply that decimal with the number given.

Here, we want to find 250% of $450. First, lets convert 250% to decimal:

250/100 = 2.5

So, 250% = 2.5

Now we multiply this with $450 to find rent in Manhattan:

2.5 * 450 = $1125

That's a whooping price of $1125 in Manhattan!!

Oksana_A [137]

Answer:

A. 7 years old

Step-by-step explanation:

6x-7=35 is the equation.

Add 7 to both sides, which gives you 6x=42.

Then both sides by 6, so 6/6=x and 42/6=7

So, x=7.

Since x is his daughter's age, x=7, so his daughter is 7.
