Answer: 3x-180
Step-by-step explanation:
Given: Expression for Revenue = 
Expression for Cost = 
If profit is the difference between the revenue and the cost then the expression for profit will be:
Profit = Revenue - cost
![=5x^2 + 2x - 80-(5x^2- x + 100)\\\\=5x^2 + 2x - 80-5x^2+x-100\ \ [\text{Multiply ' - ' sign inside the bracket}]\\\\=2x+x-80-100\\\\=3x-180](https://tex.z-dn.net/?f=%3D5x%5E2%20%2B%202x%20-%2080-%285x%5E2-%20x%20%2B%20100%29%5C%5C%5C%5C%3D5x%5E2%20%2B%202x%20-%2080-5x%5E2%2Bx-100%5C%20%5C%20%5B%5Ctext%7BMultiply%20%27%20-%20%27%20sign%20inside%20the%20bracket%7D%5D%5C%5C%5C%5C%3D2x%2Bx-80-100%5C%5C%5C%5C%3D3x-180)
Hence, the expression represents the profit is 3x-180 .
Answer:
Step-by-step explanation:
Given that,pros.
lpsa = 1.507 + 0.719 lcavol
lpsa=0.719 lcavol + 1.507
Comparing this to equation of a straight line, y=mx+c
Then,
slope (m) = 0.719
And intercept (c) on y axis is 1.507
Then, the x axis is lcavol
Also, the y axis is lpsa.
Then the linear model preview is

Answer:
B
Step-by-step explanation:
Most definitely B because all the x's and y's multiply each other to 1
Let's solve your equation step-by-step.
2.5(6x−4)=10+4(1.5+0.5x)
Step 1: Simplify both sides of the equation.
2.5(6x−4)=10+4(1.5+0.5x)
(2.5)(6x)+(2.5)(−4)=10+(4)(1.5)+(4)(0.5x)(Distribute)
15x+−10=10+6+2x
15x−10=(2x)+(10+6)(Combine Like Terms)
15x−10=2x+16
15x−10=2x+16
Step 2: Subtract 2x from both sides.
15x−10−2x=2x+16−2x
13x−10=16
Step 3: Add 10 to both sides.
13x−10+10=16+10
13x=26
Step 4: Divide both sides by 13.
13x
13
=
26
13
x=2
Answer:
x=2
First, to rewrite something in scientific notation, we want to move the decimal point a number of times to the right or left to end with a number between 0 and 10. In this case, we want to move the decimal point 7 times to the left to get the number 1.304. In scientific notation, this would be the same as 1.304*10^7.
I hope this helps!
