Answer:
(6, 0)
Step-by-step explanation:
x+3y=6
x=6-3y
subsitute x into the first equation
(6-3y)+3y=6
6-6y=6
-6y=0
y=0
Do the next equation
x=6-3(0)
x=6
a) If a/b=3/4, find: 6a+b/3a+2b
Answer:
22/17
Step-by-step explanation:
If a/b = 3/4, then a = 3 and b = 4.
6a + b/3a + 2b
Substitute the variables.
6(3) + 4/3(3) + 2(4)
Multiply 6 and 3, 3 and 3, and 2 and 4.
18 + 4/9 + 8
Add 18 and 4, 9 and 8.
22/17.

After the community clean up, the ecology club collected all the empty drink containers. There were 40 more 5 cent deposit containers than 10 cent deposit containers. If the club received $24.80 from the recycling center, how many 5 cent deposit containers did they have?
The number of 5-cent deposit containers the ecology club collected is 192.
What are the linear equations that represent the question?a - b = 40 equation 1
0.05a + 0.1b = $24.80 equation 2
Where:
a = number of 5-cent deposit containers b = number of 10- cent deposit containers.How many 5-cent deposit containers were collected?
The first step is to multiply equation 1 by 0.1
0.1a - 0.1b = 4 equation 3
Add equation 3 and equation 1
$28.80 = 0.15a
a = $28.80 / 0.15
a = 192

Use the distributive property to expand the following expression. Then combine the like terms.
-3(-2b + 5a + 7n - 10a + 6n +4a)
(please help me!!)
Answer:
6b + 3a - 39n
Step-by-step explanation:
Expanding using the distributive property :
-3(-2b + 5a + 7n - 10a + 6n +4a)
Multiply all values in the bracket by - 3
6b -15a - 21n + 30a - 18n - 12a
Collect like terms
6b - 15a + 30a - 12a - 21n - 18n

HELPP find the area of this shape / will mark brianliest
Answer:
222 cm
Step-by-step explanation:
To find the area of the square we multiply length and height.
15x12 = 180
For the triangular part of the trapezoid we multiply height by width and divide by 2.
12x7 = 84 / 2 = 42
Add the two sums and we get 222 cm.
180 + 42 = 222

Zane needs 20 yards of fencing to go around his rectangular yard. What are possible dimensions for Zane's yard? Select all that apply .
Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards

Una pelota sale disparada desde el nivel del suelo, con una velocidad de 40 m/s y un ángulo de elevación de 50°. a) Calcule la altura máxima que alcanza la pelota
Respuesta:
Los 47.85m
Explicación paso a paso:
Altura máxima = u²sin²Ф / 2g
Dado
velocidad u = 40 m / s
Ф = 50 °
g = 9,81 m / s²
Sustituir'
H = 40²sin²50 / 2 (9,81)
H = 1600 (0,7660) ² / 19,62
H = 1600 (0,5868) /19,62
H = 938,8096 / 19,62
H = 47,85 m
Por lo tanto, la altura máxima es de 47,85 m.

can someone please help me find the domain and range
Answer:
got u
Step-by-step explanation:
domain is all real numbers
range is -2
Answer:
Domain: (-∞,∞)
Range: [-2,∞)
Step-by-step explanation:
The domain is (-∞,∞) because any real input for x works for any output of y.
The range is [-2,∞) because no y-value can be less than -2 for any real input x, but the range does include -2 (for example if x=3).
