Answer:
Eric can either charge $10 or $40 in order to break even.
Step-by-step explanation:
Eric has a summer lawn mowing business and the equation:
Models his total profit <em>p</em> by charging <em>x</em> dollars per lawn.
We want to determine what price Eric needs to charge in order to break even.
The price Eric charges to break even means that his total profit will be zero. Hence, we can let <em>p</em> = 0 and solve for <em>x</em>. Thu:
We can divide both sides by -3:
Factor:
Zero Product Property:
Solve for each case. Hence:
Therefore, Eric can either charge $10 or $40 in order to break even.
Rate of change is like slope. Change in y/ change in x
First we have to solve for the y.
x^2 -3x -4 when x = 7
7^2 -3(7)-4= 24 (7,24)
x^2-3x-4 when x=10
10^2-3(10)-4= 66 (10,66)
(66-24)/(10-7)
42/3 = 14
Answer:
C x=6
Step-by-step explanation:
4x-5=19
+5 on both sides
4x=24
divide both sides by 4
x=6
Answer:
s = 23
Step-by-step explanation:
1. VW ≅ VY is given.
2. XV ≅ VX as it is the same side.
3. ∠WVX ≅ ∠YVX as they are both 90°. ∠WVY is 180° as it is a straight line, so both ∠WVX and ∠YVX are exactly half of that.
Given those three things, you can say that ΔWVX ≅ ΔYVX. Because all corresponding parts of congruent triangles are also congruent, you can be sure that WX ≅ XY. Finally, using that information, you can write an equation and solve for s.
