What is 1 1/2 x 3/4?​

2 1/4

Step-by-step explanation:

First you have to do 2 x 1 = 2

Then add 2 + 1 = 3

Next do 3/2 x 3/4

You will have to find the common denominator which is 8

Do 4 x 3 = 12 and 3 x 2= 6

Add 12 + 6 = 18

You get the answer 18/8

You can go and put this answer into an improper fraction

2 2/8

Since 2/8 can be divided by 2

You will get an answer of 2 1/4

4 1/8

Step-by-step explanation:

first, you do 11 * 3/ 2* 4 which equals 33/8.

Then you simplify 33/8 which is 4 1/8

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i believe that the answer is

b. y-1=-2(x-4)

hope this !
