Solve the following system of equations. y + 5x = 30 2y = 5x + 15
Answer: Solve 2y-5x-30 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2y-5x-30 = 0 and calculate its properties
Step-by-step explanation:
Answer:
x = 3, y = 15
Step-by-step explanation:
Given the 2 equations
y + 5x = 30 → (1)
2y = 5x + 15 → (2)
Subtract 5x from both sides in (1)
y = 30 - 5x → (3)
Substitute y = 30 - 5x into (2)
2(30 - 5x) = 5x + 15 ← distribute left side
60 - 10x = 5x + 15 ( subtract 5x from both sides )
60 - 15x = 15 ( subtract 60 from both sides )
- 15x = - 45 ( divide both sides by - 15 )
x = 3
Substitute x = 3 into (3) for corresponding value of y
y = 30 - 5(3) = 30 - 15 = 15
Thus solution is x = 3, y = 15

Given the following function, find f(-4), f(0), and f(4).
f(x) = x + 2
f(-4)=
f(0) =
f(4)=
Answer:
-2, 2, 6
Step-by-step explanation:
f(-4)= -4+2=-2
f(0)=0+2=2
f(4)=4+2=6
Substitute x for the number in parentheses
The values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function f(x) = x + 2
To find the value of f(-4):
Plug x = -4 in the function:
f(-4) = -4 + 2 = -2
To find the value of f(0):
Plug x = 0 in the function:
f(0) = 0 + 2 = 2
To find the value of f(4):
Plug x = 4 in the function:
f(4) = 4 + 2 = 6
Thus, the values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

A population of 40 rats living near a restaurant dumpster is growing at a monthly rate of 50%
Write an equation for this scenario
[(40 ÷ .5) Y] + 40
Parentheses are rat growth
Brackets are rat growth by how many years or just exclude that and the brackets if you don't need to know how many years are there are
The 40 is the amount of rats already there
Growth of rats plus the amount already there.
I'm probably wrong lol

Sadie spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -6.2°F. Between 9am and noon, the temperature increased by 2.6°F. Between noon and 3pm, the temperature dropped 18.6°F. Between 3pm and 6pm, the temperature dropped 6.5°F. What was the temperature at 6pm
Answer:
-28.7
Step-by-step explanation:
-6.2 + 2.6 = -3.6 - 18.6 = -22.2 - 6.5 = -28.7

Elsa is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 43 feet and its width is 36 feet. Suppose each can of wood stain covers 172 square feet. How many cans will she need to cover the court?
Answer:
Step-by-step explanation:
find the area which is length divided by width then divide by 172 which is what each can covers. So, 43x36 =1548 and 1548/172 equals 9. So 9 is the answer
If p varies directly as
the cube of q, and p =
26 when q = 2, find p
when q = 5
Answer:
The value of p at q = 5 is 406.25
Step-by-step explanation:
∵ p varies directly as the cube of q
→ That means p ∝ q³
∴ The equation of variation is p = kq³, where k is the constant of variation
∵ p = 26 when q = 2
→ Use them to find the value of k
∵ 26 = k(2)³
∴ 26 = k(8)
∴ 26 = 8k
→ Divide both sides by 8
∴ [tex]\frac{26}{8}=\frac{k}{8}[/tex]
∴ 3.25 = k
→ Substitute it in the equation of variation
∴ p = 3.25 q³ ⇒ equation of variation
∵ q = 5
→ Substitute it in the equation of variation to find p
∴ p = 3.25 (5)³
∴ p = 406.25
∴ The value of p at q = 5 is 406.25
