81=b
y=11x+81
At a bakery, cupcakes cost $4 each and brownies cost $3 each. Which equation represents the total cost, T, of c cupcakes and b brownies?
Answer: 3b + 4c = T
Since brownies are three dollars and cupcakes are four, we simply do the amount of items bought multiplied by three or four.

plz hlp
Answer:
Check the solution below
Step-by-step explanation:
2) Given the equation
x +y =5... 1 and
x-y =3 ... 2
Add both equations
x+x = 5+3
2x = 8
x = 8/2
x = 4
Substitute x = 4 into 1:
From 1: x+y = 5
4+y= 5
y = 5-4
y = 1
3) Given
x+3y =15 ... 1
2x+7y=19 .... 2
From 2: x = 15-3y
Substitute into 2
2(15-3y)+7y = 19
30-6y+7y = 19
30+y = 19
y = 19-30
y = -11
Substitute y=-11 into x = 15-3y
x =15-3(-11)
x = 15+33
x = 48
The solution set is (48, -11)
4) given
x/2 +y/3 =0 and x+2y=1
From 1
(3x+2y)/6 = 0
3x+2y = 0.. 3
x+2y= 1... 4
From 4: x = 1-2y
Substutute
3(1-2y) +2y = 0
3-6y+2y = 0
3 -4y = 0
4y = 3
y = 3/4
Since x = 1-2y
x = 1-2(3/4)
x = 1-3/2
x= -1/2
The solution set is (-1/2, 3/4)
5) Given
5.x=1/2 and y =x +1 then solution is
We already know the vkue of x
Get y
y= x+1
y = 1/2 + 1
y = 3/2
Hence the solution set is (1/2, 3/2)
6) Given
3x +y =5 and x -3y =5
From 3; x = 5+3y
Substitute into 1;
3(5+3y)+y = 5
15+9y+y = 5
10y = 5-15
10y =-10
y = -1
Get x;
x = 5+3y
x = 5+3(-1)
x = 5-3
x = 2
Hence two solution set is (2,-1)

At a carnival, the dart game costs $0.50 to play and the ring toss game costs $0.25 to play. You have $5 to spend on the two games. Write an inequality for the number of times you can play the two games.
Answer:
0.5x + 0.25y ≤ $5
Step-by-step explanation:
Let the number of times you can play dart game = x
The number of times.you can play ring toss games = y
At a carnival, the dart game costs $0.50 to play and the ring toss game costs $0.25 to play. You have $5 to spend on the two games.
Write an inequality for the number of times you can play the two games.
Hence, the inequality =
0.5x + 0.25y ≤ $5
Let p represent a true statement, let q and r represent the false statements. Find the
truth value of the given compound statements.
~(pvq) ^~(p^q)
Solutions:
If p is true and q is false, then
• p ∨ q is true, and so ¬ (p ∨ q) is false (¬ stands for "negation" or "not")
• p ∧ q is false, and so ¬ (p ∧ q) is true
which means
¬ (p ∨ q) ∧ ¬ (p ∧ q)
is false.

Translate the sentence into an inequality. Twice the difference of a number and 2 is at least 21. Whoever is correct gets brainliest!
Answer:
2(c-2) >= 21
Step-by-step explanation:
At least means the smallest number must be, so the symbol is greater than or equal to for 21 to be the smallest possible number.
For twice the difference of a number and 2, we need the difference first, then we multiply by 2, hence 2(c-2).
Combining all of our previous information, 2(c-2) >= 21.

A pilot flew a 400-mile flight in 2.5 hours flying into the wind. Flying the same rate and with the same wind speed, the return trip took only 2 hours, with a tailwind.
What was the speed of the wind?
Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.

Answer:
The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution
which of the following rational functions is graphed below?
The rational function graphed below is: [tex]\(f(x) = \frac{1}{(x + 3)(x - 3)}\)[/tex]
To determine the rational function graphed below, let's analyze the key features of the graph.
The graph appears to have two vertical asymptotes at [tex]\(x = -3\)[/tex] and [tex]\(x = 3\)[/tex] since the denominator [tex]\((x + 3)(x - 3)\)[/tex] becomes zero at those points, and division by zero is not defined. Vertical asymptotes are represented by vertical lines that the graph approaches but never touches.
The graph also seems to cross the x-axis at [tex]\(x = -3\)[/tex] and [tex]\(x = 3\)[/tex] since the numerator 1 is nonzero at those points, causing the function to have y-intercepts at those locations.
Furthermore, the graph appears to be symmetrical with respect to the vertical line x = 0 because the rational function is an even function. This is evident from the fact that the terms [tex]\((x + 3)\) and \((x - 3)\)[/tex] in the denominator are identical except for the sign. Therefore, the function has symmetry about the y-axis.
Considering all these characteristics, the rational function that matches the given graph is:
[tex]\(f(x) = \frac{1}{(x + 3)(x - 3)}\)[/tex].
This function has vertical asymptotes at [tex]\(x = -3\) and \(x = 3\)[/tex], crosses the x-axis at [tex]\(x = -3\) and \(x = 3\)[/tex], and is symmetric with respect to the y-axis. The graph should resemble a hyperbola centered at the origin.

The Jones family eats 2/3 of a packet of biscuits every day. How long will 27 packets last the family?
Answer:
40 1/2 days
Step-by-step explanation:
Quantity of biscuits the Jones eats daily = 2/3 of a packet
Total packets of biscuits = 27 packets
How long will 27 packets last the family?
= Total packets of biscuits / daily intake of biscuits of the Jones
= 27 ÷ 2/3
= 27 × 3/2
= 81 / 2
= 40 1/2 days
