Answer:
The second one: [tex]8x^{2}y+7x^{2}-5y^{2}+3x-2+2x^{2}y-x^{2}-2y^{2}-3x-4[/tex]
Step-by-step explanation:
You have to combine the like terms (any numbers with the same variables and exponents)
[tex]8x^{2}y+2x^{2}y=10x^{2}y, 7x^{2}-x^{2}=6x^{2}, -5y^{2}-2y^{2}=-7y^{2}, 3x-3x=0, -2-4=-6[/tex]
If you put all of the answers together you get [tex]10x^{2}y+6x^{2}-7y^{2}-6[/tex]

what is the distance between the two points A(6,-2) and B(-2,4)
Answers
Answer:
[tex]d = 10[/tex]
Step-by-step explanation:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-2-6)^2+(4-(-2))^2}[/tex]
[tex]d = \sqrt{(-8)^2+(4+2)^2}[/tex]
[tex]d = \sqrt{64+(6)^2}[/tex]
[tex]d = \sqrt{64+36}[/tex]
[tex]d = \sqrt{100}[/tex]
[tex]d = 10[/tex]
Answer:
10 units
Step-by-step explanation:
( x1, y1) =A(6,-2)
(x2, y2) =B(-2,4)
Using distance formula,
AB ^2 = (x2-x1) ^2 +(y2-y1) ^2
=(-2-6)^2 +(4+2)^2
=64+36
=100
Therefore, AB=10 units

Answers
Answer: image below is the answer
Step-by-step explanation:
$1.80 + $1.20 = $3.00 < $1.86 + $1.23 < $2.00 + $1.50 = $3.50
Double these supplies will cost between 2 × $3.00 and 2 × $3.50.
Suppose Kira started with 2 pencils.2 x $1.23 = $2.46
Think about more items Kira could buy so that her total cost is more than $4 but less than $6.
Suppose Ida started with 1 drawing pad and 2 pencils.$1.80 + ($1.10 x 2) = $4.00 < $1.86 + ($1.23 x 2) < $2.00 + ($1.25 x 2) = $4.50
Think about more items Ida could buy so that her total cost is more than $8 but less than $9.
AnswerJulio: $6 - $7

two drawing pads
Kira: $4 - $6

Ida: $8 - $9

The number of words Gabriel can type varies directly with time. Gabriel can type 90 words in 65 seconds. Which equation can be used to find w, the number of w Gabriel can type at this rute in 125 seconds?
w = 90/65 (125)
w = 90(125)/125
w = 125/ 90/ (65)
w = 65/90 (125)
Answers
Answer:
w = 90/65 (125)
Step-by-step explanation:
Since you are trying to find how much Gabriel can type in 125 seconds, you have to find how much he can type in 1 second. Then you can multiply by 125 to get your answer!

Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours. Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours. What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings? Write an inequality that could be used to solve this problem
Answers
Answer:
3 hours
Step-by-step explanation:
Let the number of hours worked = x
Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours.
$500 + $100 × x
500 + 100 × 1
After the first 2 hours = $500 + $100
= $600
After the first 3 hours = $500 + $100 × 2
= $700
Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours.
$620 + $70 × x
620 + 70x
After the first 3 hours
= $600 + $70
= $670
What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings?
The Inequality is given as:
Cathy's Catering for < Delicious Doings
620 + 70x < 500 + 100x
Collect like terms
620 - 500 < 100x - 70x
120 < 30x
120/30 < x
4 < x
Therefore, the most amount of hours the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings is 3 hours
