The answer for this problem i −10x2+66xy−36y2−5x+3y

Let's solve it by step by step.

(−5x+3y)(2x−12y+1)

=(−5x+3y)(2x+−12y+1)

=(−5x)(2x)+(−5x)(−12y)+(−5x)(1)+(3y)(2x)+(3y)(−12y)+(3y)(1)

=−10x2+60xy−5x+6xy−36y2+3y

So, -10x2+66xy-36y2-5x+3y

Consider the equation below.

Kamila [148]

Answer:

Option (1)

Step-by-step explanation:

$\text{log}_4(x + 3)=\text{log}_2(2 + x)$

$\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}$

$\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}$

System of equations can be written as,

$y_1=\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}$

$y_2=\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}$

Therefore, system of equations given in Option (1) is the correct option.

Daniel says that more than half the students spent 2 1 2 hours or more on homework. Liz says more than half the students spent l

Thepotemich [5.8K]

Answer:

Liz is correct

Step-by-step explanation:

Given

See attachment for complete question

Required

Who is correct? Daniel or Liz

From the attached data, we have:

$Time: 1\frac{3}{4},\ 2\frac{1}{2},\ 2,\ 2\frac{3}{4},\ 1,\ 1\frac{3}{4},\ 1\frac{1}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4},\ 2,\ 2$

The total number of students is:

$n = 12$

The data that represents $2\frac{1}{2}$ or more is:

$Time: 2\frac{1}{2},\ 2\frac{3}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4}$

The frequency of this is 5

The frequency that represents $2\frac{1}{2}$ or less will be 7

This means that less than half spend $2\frac{1}{2}$ or more

and more than half spend $2\frac{1}{2}$ or more

Hence, Daniel is incorrect. Liz is correct
