0.78p = 2.73.....with p being the number of lbs
divide both sides by 0.78
p = 2.73 / 0.78
p = 3.5 lbs <=== ur answer
Answer:
no solutions
Step-by-step explanation:
4 + 5m = 4m + 1 + m <em>combine like terms</em>
4 + 5m = 5m + 1 <em>subtract 5m from each side</em>
4 = 1
4 can never equal 1, so no value of m would allow the equation to be correct
Answer:
y=2x-7
Step-by-step explanation:
The easiest way to answer this would be by using the slope-intercept form equation, y=mx+b. In this case, we can use our given in information to plug in values and find the equation.
Firstly, let's assess what know and what we don't:
Given the point (2,-3), we know that x=2 and y=-3. Now the slope for a perpendicular line can be found using a negative reciprocal, since the product of the slopes of both lines should equal -1. Therefore the slope must be 2.
All that's left is b, the y-intercept. To solve for this, we simply plug in what we have.
y=mx+b
-3=2(2)+b
-3=4+b
-3-4=b
-7=b
Now that we have b, we can write the equation:
y=2x-7

Answer:
y = 7
Step-by-step explanation:
The y-axis is the vertical line x=0. A perpendicular line will be a horizontal line that will have an equation of the form ...
y = constant
In order for that line to go through a point with y-coordinate 7, the line must be ...
y = 7
