Answer:
[tex]\huge\boxed{x=0,\ y=3\to(0;\ 3)}[/tex]
Step-by-step explanation:
[tex]\left\{\begin{array}{ccc}x+3y=9&\text{subtract }3y\ \text{from both sides}\\4x-2y=-6\end{array}\right\\\\\left\{\begin{array}{ccc}x=9-3y&(1)\\4x-2y=-6&(2)\end{array}\right[/tex]
Substitute (1) to (2):
[tex]4(9-3y)-2y=-6\qquad|\text{use the distributive property}\\\\(4)(9)+(4)(-3y)-2y=-6\\\\36-12y-2y=-6\qquad|\text{subtract 36 from both sides}\\\\-14y=-42\qquad|\text{divide both sides by (-14)}\\\\y=3[/tex]
Put it to (1):
[tex]x=9-3(3)\\\\x=9-9\\\\x=0[/tex]
A movie theater has 400 seats. Tickets at the theater cost $8 for students, $10 for adults, and $7 for senior citizens. On a night when all the seats were sold, the theater made $3,535 from ticket sales. If the number of adult tickets sold was 10 less than the number of student and senior tickets combined, how many senior tickets were sold?
55 senior tickets
150 senior tickets
195 senior tickets
255 senior tickets
Answer:
55 senior tickets
Step-by-step explanation:
400 seats
students: $8
Adults: $10
Seniors: $7
All seats were sold and the total money they got was $3,535
Adult tickets sold was 10 less than the # of student and seniors combined.
8a+10b+7c=3535
a+b+c=400 now just solve for them
8a+10b+7c=3535
-8a-8b-8c=-3200
2b-c=335...
If you solve for the numbers, you'll get 55 tickets.

HURRY PLEASE On a coordinate plane, point A is 2 units to the left and 5 units up. Point B is 5 units to the right and 5 units up. What is the distance between the points? Point A is located at the point . Point B is located at the point . The distance between the points is units.
Answer:
point A is located at (-2,5) and point B is located at point (5,5), the distance between the points is 7 units. hope this helps!
The distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).
What is distance between points?The formula of distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
We have,
Point A (-2, 5) and Point B (5, 5).
i.e.
x₁ = -2, x₂ = 5 and
y₁ = 5, y₂ = 5
Now,
Using the above mentioned formula of distance,
i.e.
Distance [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
So,
Substituting values,
Distance [tex](A,B) = \sqrt{(5-(-2) )^2 + ( 5-5)^2}[/tex]
Now, simplify,
Distance [tex](A,B) = \sqrt{(7)^2 + 0}[/tex]
We get,
Distance [tex](A,B) = 7[/tex]
So, the distance between AB is 7 units.
Hence, we can say that the distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).

Write an equation in slope-intercept form for the line that passes through (4, 1) and is parallel to the line y-1/4x+7
Answer and I will give you brainiliest
Answer:
y=¼x
Step-by-step explanation:
Parallel lines have the same slope
The slope of the given line is ¼,thus,
y-¼x+7=0
y=¼x-7
Now using the point-slope form y-y1=m(x-x1)
y-1=¼(x-4)
4y-4=x-4
4y=x-4+4

Brenda is selling two different not mixes as snacks. Mix A has 3 oz. of cashews and 7 oz. of almonds. Mix B has 6 oz. of cashews and 5 oz. of almonds. Which inequalities represent the number of mix A mixes, and mix B mixes, B, Brenda can make if she has 72 oz. of cashews and 84 oz. of almonds.
Answer:
Mix A ≤ 12
Mix B ≤ 12
Step-by-step explanation:
Mix A requires 3 oz of cashews and 7 oz of almonds
Mix B requires 6 oz of cashews and 5 oz of almonds
If Brenda makes just Mix A using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/3=24 Mix A snacks
With 84 oz of almond, she would potentially make 84/7=12 Mix A snacks
Since she would require both cashews and almonds to make Mix A snacks, she would be able to make 12 mix A snacks
Inequality would be:
Mix A ≤ 12
If Brenda makes just Mix B using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/6=12 Mix B snacks
With 84 oz of almond, she would potentially make 84/5=16 (approximately) Mix B snacks
Since she would require both cashews and almonds to make Mix B snacks, she would be able to make 12 mix B snacks
Inequality would be:
Mix B ≤ 12

Shiloh needs to randomly select one of the six days between Sunday and Friday. Which simulation tools could she use in this situation?
((( MULTIPLE ANSWERS))
A-a spinner divided evenly into 12 sections, with each section a different color
B-two coins
C-a six-sided number cube
D-a bag containing 12 chips in two different colors, with six of each color
E-two full suits from a standard deck of cards
Answer:
The correct answer is C. She could use a six-sided number cube.
Step-by-step explanation:
Since Shiloh has 6 options from which to choose a unique alternative, it can be stated that her eligibility ratio is 1/6. Thus, since the dice has 6 numbers and only 1 will come up face up, the option of the dice is the most appropriate to make her decision.
On the other hand, the other options do not contemplate 6 possibilities but 12, 2, 12 and 13 possibilities respectively, with different possible alternatives, which does not give an equitable distribution of possibilities between each option.

the ratio of strawberries to grapes in the fruit salad is 3:9. the ratios of strawberries to honey dew is 6:14. if there 36 grapes. how many strawberries?
Answer:
12 strawberries
Step-by-step explanation:
Represent strawberry with S, grape with G and honeydew with H
Given
[tex]S : G = 3 : 9[/tex]
S : H = 6 : 14
Required
Solve for S when G = 36
To do this, we make use of the first ratio
[tex]S : G = 3 : 9[/tex]
Substitute 36 for G
[tex]S : 36 = 3 : 9[/tex]
Convert to fractions
[tex]\frac{S}{36} = \frac{3}{9}[/tex]
[tex]\frac{S}{36} = \frac{1}{3}[/tex]
Multiply both sides by 36
[tex]36 * \frac{S}{36} = \frac{1}{3} * 36[/tex]
[tex]S = \frac{1}{3} * 36[/tex]
[tex]S = \frac{36}{3}[/tex]
[tex]S = 12[/tex]
Hence, there are 12 strawberries

How many four digit numbers can be formed using the digits 7, 6, 5 and 2 if
repetitions are allowed?
Answer: The number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256
Step-by-step explanation:
Given digits = 7, 6, 5 and 2
If repetition is allowed , we can use Fundamental principal of counting.
By this principal , total four digit numbers can be formed = 4x 4x4 x 4 [∵ choice for each place = 4 ]
= 256
Hence, the number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256
