I'm assuming you want to factor this?
So first, use the distributive property.

10x^2+6xy-14xy-14y^2
10x^2-8xy-14y^2

Next take out the GCF of 2
2(5x^2-4xy-7y^2)

Next factor 
2(5x-7y)(x+y)

Ms.Shanks collects money for a fundraiser while she has fractions on her mind. She collects $1 3/4,$3/4,$1/4,$2 2/4,and $1 from
MA_775_DIABLO [31]

Answer:

$6.25 or $6 and 25 cents

Step-by-step explanation:

Ms.Shanks collects \$1\dfrac{3}{4},\ \$\dfrac{3}{4},\ \$\dfrac{1}{4},\ \$2\dfrac{2}{4},and \$1 from five of her students.

In total she collects

\$\left(1\dfrac{3}{4}+\dfrac{3}{4}+\dfrac{1}{4}+2\dfrac{2}{4}+1\right)=\$\left(1+2+1+\dfrac{3}{4}+\dfrac{3}{4}+\dfrac{1}{4}+\dfrac{2}{4}\right)=\$\left(4+\dfrac{9}{4}\right)=\\ \\\$\left(4+2\dfrac{1}{4}\right)=\$6\dfrac{1}{4}

Note that

\$6\dfrac{1}{4}=\$6.25 ($6 and 25 cents)

Now check in decimals:

\$1\dfrac{3}{4}=\$1.75\\ \\\$\dfrac{3}{4}=\$0.75\\ \\\$\dfrac{1}{4}=\$0.25\\ \\\$2\dfrac{2}{4}=\$2.50\\ \\\$1=\$1

So, the sum is

\$1.75+\$0.75+\$0.25+\$2.50+\$1=\$1.75+\$1+\$3.50=\$1.75+\$4.50=\$6.25

WARNING!!!! Lots of questions, but worth it, 100 points
ad-work [718]

Answer:

1.)   y= -3/5  x + 4

The table should be:

<h2>x | 10    5    -5    -10</h2><h2>y | -2     1     7      10</h2>

The numbers should align.  The equation should be a connected line and the table coordinates should be points located on that connected line.

2.)  y= -3/2  x + 1

The table should be:

<h2>x |  4    2    -2    -4</h2><h2>y | -5   -2     4     7</h2>

Same thing as the last problem just in reverse.

5.) I'm sorry, I do not know how to solve this word problem.

8.)

<h2>C, is the correct  graph.</h2><h2 />

9.)

-15-5x+15 ≤ 0+15

5x ≥ -15

5x -15   - After simplifying.

5x/5 ≥ -15/5   - Simplify.

<h2>x ≥ -3</h2>

I hope I helped you love!
