Answer:
18x²y - 8a + 14bStep-by-step explanation:
The Sum:
3x²y - 5a + 4b + (-9x²y - 7b + 4a) = 3x²y - 9x²y - 5a + 4a + 4b - 7b = -6x²y - a - 3bThe difference:
3x²y - 5a + 4b - (-9x²y - 7b + 4a) =3x²y + 9x²y - 5a - 4a + 4b + 7b =12x²y - 9a + 11bSubtract the sum from the difference:
12x²y - 9a + 11b - (-6x²y - a - 3b) = 12x²y + 6x²y - 9a + a + 11b + 3b =18x²y - 8a + 14bAnswer:
See below.
Step-by-step explanation:
First Let's us find the sum.
[tex]\sf\longmapsto \: 3x²y - 5a + 4b + (-9x²y - 7b + 4a)[/tex]
[tex]\sf\longmapsto3x²y - 9x²y - 5a + 4a + 4b - 7b [/tex]
[tex]\sf\longmapsto \: -6x²y - a - 3b[/tex]
Now, let's us find the difference (minus)
[tex]\sf\longmapsto \: 3x²y - 5a + 4b - (-9x²y - 7b + 4a)[/tex]
[tex]\sf\longmapsto3x²y + 9x²y - 5a - 4a + 4b + 7b[/tex]
[tex]\sf\longmapsto \: 12x²y - 9a + 11b[/tex]
Now minus the sum from the difference.
[tex]\sf\longmapsto \: 12x²y - 9a + 11b - (-6x²y - a - 3b)[/tex]
[tex]\sf\longmapsto \: 12x²y + 6x²y - 9a + a +11b + 3b[/tex]
[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex]
Therefore,[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex] is the answer.

Find the equation that passes through (2, 2) and is parallel to 2y + 4x = 4.5
Answers
Answer:
Line passing through (2,2) is parallel to X - 2Y = 4, so, the slope is same as given line.
m = -a/b = -1/-2 = 1/2
The equation is
(Y - Y1) = m(X - X1) => Y - 2 = 1/2(X - 2) =>
2Y - 4 = X - 2 => | X - 2Y = -2 |

From his home, Dan would have to walk due north to get to his friend Samuel's house and due east to get to his friend Cindy's house. It is 3 kilometers from Dan's house to Cindy's house and a straight-line distance of 5 kilometers from Samuel's house to Cindy's house. How far is Dan's house from Samuel's house?
Answers
The distance from Dan's house to Samuel's house is 4 km
The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.
Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km
Pythagoras theorem shows the relationship between the lengths of a right angled triangle.
Using Pythagoras theorem:
5² = x² + 3²
25 = x² + 9
x² = 16
x = 4 km
Hence the distance from Dan's house to Samuel's house is 4 km

Mr. and Mrs. Smith's children all play different sports. They want to buy a combination of soccer
training sets, which each cost $149, volleyball training set, which each cost $127, and football
training sets which each cost $275. Let s represent number of soccer sets, v represent number of
volleyball sets and frepresent the number of football sets. Which expression represents the total
amount of money the Smiths will spend, before sales tax, based on the number of sports sets they
buy?
Answers
Answer:
149sx+127v+275f =
276
Step-by-step explanation:
multiply all the numbers than add you get the answer 149sx+127v+275f
149s + 127v + 275f is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.
What is Expression?An expression is combination of variables, numbers and operators.
The total amount of money the Smiths will spend on the soccer, volleyball, and football training sets can be represented by the expression:
149s + 127v + 275f
Here, 149s represents the cost of s soccer training sets,
127v represents the cost of v volleyball training sets, and
275f represents the cost of f football training sets.
To find the total amount of money the Smiths will spend based on the number of sports sets they buy, simply substitute the corresponding values of s, v, and f into the expression above and simplify.
Hence, 149s + 127v + 275f is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.

For her grandfather's birthday, Valeria is baking cupcakes. With every egg she can find, she can bake 6 cupcakes.
Write an equation that shows how the total number of cupcakes Valeria can bake, y, depends on the number of eggs she can find, x.
Answers
The equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.
Number of cupcakes that can be baked with 1 egg = 6
Let the total number of eggs be represented by x.
Let the total number of cupcakes be represented by y.
Therefore, the total number of cupcakes will then be:
y = 6 × x
y = 6x
Therefore, the equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.

Answers
Answer:

Step-by-step explanation:
since it's square units and this is a right triangle
area = (width * height) / 2
area = 6 * 3 / 2
area = 18 / 2
area = 9 square units²
Answer:
9 [tex]units^{2}[/tex]
Step-by-step explanation:
The formula to find the area of a triangle is [tex]A=\frac{1}{2}b*h[/tex] where b is the base or bottom of the triangle and h is the height of the triangle.
The base of the triangle in the picture is 6 units.
The height of the triangle in the picture is 3 units.
Substituting these values into the area formula:
[tex]A=\frac{1}{2}(6*3)=\frac{1}{2}(18)=9[/tex]
So the area of the triangle is 9 [tex]units^{2}[/tex]

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (8, 7) and (-4,3)
Answers
Answer:
y = -3x + 11.
Step-by-step explanation:
The slope of the given line segment is (3-7)/(-4-8) = -4/-12 = 1/3.
The midpoint of the line has coordinates (8-4)/2, (7+3)/2.
= (2, 5).
The slope of the perpendicular bisector = -1/ 1/3 = -3.
So it's bisector has equation:
y - y1 = m(x - x1)=
y - 5 = -3(x - 2)
y = -3x + 6 + 5
y = -3x + 11.

Four different stores are offering incentives to purchase headphones as shown below. Noisy Music Regular Price $250 Clearance Special - 15% off Loud N Sharp Regular Price $200 $5 off for every $100 spent Music Mart Regular Price $300 Mail-in rebate for $115 Head Jamz Regular Price $225 Manager special – 25% off Which store offers the lowest price?
Answers
Answer:
Head Jamz
Step-by-step explanation:
Noisy Music Regular Price $250 Clearance Special - 15% off
If 15% is off then we pay only 100-15 =85% from the original price.
$250 / 100 % = x / 85%
x= 250*85/100 = $ 212.5
Loud N Sharp Regular Price $200 $5 off for every $100 spent
If the price is 200 then will get $5+$5 =$10 discount
Final price will be 200-10 = $ 180
Music Mart Regular Price $300 Mail-in rebate for $115
$300-$115 = $ 185
Head Jamz Regular Price $225 Manager special – 25% off
If 25% is off we only pay 75% of the original price
$225/ 100% = x / 75%
x= 225*75/ 100 = $168.75 is the lowest price

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate [tex]2(4)+4(4)+1(4)+5(4)+1(2)+3(2)[/tex], right?
Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want [tex]2(4)+4(4)+1(4)+5(4)+1(2)[/tex].
We multiply it out to get [tex]8+16+4+20+2[/tex].
We add these up to get [tex]50[/tex].

en un restaurante se usan 70 gramos por cada porción de arroz por persona.Si un día se preparan 4760 gramos de arroz ¿cuántas porciones se obtendrán?
Answers
Queremos saber cuantas porciones de arroz se preparan dado que conocemos cuantos gramos de arroz se utilizan.
Se prepararon 68 porciones.
Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.
Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.
Esto nos da:
4,760g/70g = 68
Es decir, se prepararon 68 porciones.
