Step-by-step explanation:
4x + y = 8
-4x -4x
y = -4x+8
5x + 2y = 13
-5x -5x
2y/2 = -5x/2 + 13/2
y = -5/2x+13/2
Student council is renting a tent for $350 for an upcoming student fair. Each student attending the fair will pay $0.50. All other attendees will pay $2.25 each. If 200 students attend the fair, which inequality can be used to determine the number of "other" attendees, a, needed to cover the cost of the tent?

Answer: The third one
Step-by-step explanation: open circle, with crocodile sign pointing to right which means u have to go left! Have a nice day!!
Answer:
C) a number line going from negative 6.5 to negative 5.8. An open circle is at negative 6.1. Everything to the left of the circle is shaded.
Step-by-step explanation:
Open circle means < or >
Closed circle means < or >
So has to be an open circle since the sign is <. it also says w < -6.1
so w has to be less than -6.1. So less than -6.1 would be -6.2, -6.3, -6.4etc.
Find an explicit formula for the arithmetic sequence -15, 13, 31, 49
Answer:
No solution (read below)
Step-by-step explanation:
Formula:
a_n = a_1 + (n-1)d
N is the term #
D is the common difference
First, let's find the common difference.
13 - (-15) = 28
Let's see if that checks out.
31-13 = 18
49 - 31 = 18
18 is not equal to 28
Since there is no common difference you cannot find the equation.

Answer:
11 cars/day
Step-by-step explanation:
What we know:
After two days, Car-Mart has 43 cars left. After 3 days, it is 32. After five, 10 cars.
Saying that, subtract 32 from 43 to get your rate of 11 cars sold a day.
I can further deduce they started with 76 cars. On day 1 they had 65 cars. On day 4 they had 21 cars. They will have sold all of their cars after day 6.
Write the equation of the line fully simplified slope-intercept form.
El número misterioso: soy múltiplo de 3 y de 4 y estoy comprendido entre 30 y 99. El resto de mi división por 5 es 4. ¿Quién soy?
Answer:
84
Step-by-step explanation:
Let the number be x.
As the number is multiple of 3 and 4, so the number must be a multiple of the lowest common factor (LCM) of 3 and 4.
LCM(3,4)=12
So, the number, x, is a multiple of 12.
All the numbers between 30 and 99, which are multiples of 12 are 36, 48, 60, 72, 84, 96.
When x is divided by 5, the remainder is 4, so the unit digit of the number is 4.
Now, the number between 30 and 99, which is multiple of 12 and having the unit digit 4 is 84.
Hence, the required number is 84.

In this system of equations below solve for x
2x+2y=12
x-4y=6
Answer:
X = 6
y = 0
Step-by-step explanation:
use elimination method. Multiply (x -4y = 6) by -2.
2x + 2y = 12
-2x + 8y = -12
add them together
10y = 0
y = 0
plug in for y
x - 4(0) = 6
x = 6

Answer:
Triangle RST is an equilateral triangle.
Step-by-step explanation:
All three sides of the triangle are of equal length, therefore, because an isosceles triangle is when 2 sides of the triangle are the same length, a scalene triangle being when all sides are of different lengths, and a right triangle having a right angle (a 90 degree angle), this only leaves equilateral, all three sides being the same length, like in the triangle shown.

A licensed nurse practitioner is instructed to give a patient 1500 milligrams of an antibiotic over a period of 36 hours. If the antibiotic is to be given every 2 hours starting immediately, how much antibiotic should be given in each dose? To answer this question, solve the equation 18x=1500.
Answer:
83.33 milligrams
Step-by-step explanation:
The equation, [tex] 18x = 1500 [/tex] represents the total dosage of antibiotics to be given to the patient in relation to the hours.
Thus, the each dosage = x.
Let's solve for x
[tex] 18x = 1500 [/tex]
Divide both sides by 18
[tex] \frac{18x}{18} = \frac{1500}{18} [/tex]
[tex] x = 83.33 milligrams [/tex] (nearest hundredth)

Select all of the statements that are true for the given parabola.
Answer:
A and B are true
Step-by-step explanation:
The minimum is the turning point on the graph and occurs at (1, - 2)
The x- intercepts are where the graph crosses the x- axis , that is at
x = - 1 and x = 3 or in coordinate form (- 1, 0 ) and (3, 0 )
The equation of the axis of symmetry is a vertical line passing through (1, - 2)
with equation x = 1
The true statements are A and B
Answer:
⇨ A and B choice
Step-by-step explanation:
⟺ Consider all choices.
⥱ Choice A is correct because It's upward Parabola ( a > 0) where there is only the minimum point/value. The minimum point is at (1,-2). The vertex for upward parabola can be called the minimum point.
⥱ Choice B is correct because the Parabola intercepts x-axis at (-1,0) and (3,0) from the graph.
⥱ Choice C is wrong because the Axis of Symmetry is supposed to be x-term/value for the Parabola. If it is the y-value/term then it would be Side Parabola.
⥱ Choice D is wrong because an upward Parabola doesn't have the maximum point. The only Parabola with maximum point is downward Parabola ( a < 0)

The zoo has 12 Emperor penguins, which makes up 24% of all penguins at the zoo. How many penguins live at the zoo?
Answer:
[tex]50[/tex] penguins
Step-by-step explanation:
Let [tex]p[/tex] = number of penguins at the zoo
[tex]24\%p=12[/tex] (Is given that 12 Emperor penguins at the zoo make up 24% of total penguins)
[tex]0.24p=12[/tex]
[tex]p=12\div0.24[/tex]
[tex]p=50[/tex]
∴ There are [tex]50[/tex] penguins at the zoo
