The maximum number of large binders she can buy is 5.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.
n₁Sb + n₂Lb = 45 ................................1
n₁ + n₂ = 12
Now put the value of n₁ in equation 1.
( 12 - n₂ )3 + 5n₂ = 45
36 - 3n₂ + 5n₂ = 45
2n₂ = 9
n₂ = 4.5
n₂ ≅ 5
Therefore the maximum number of large binders she can buy is 5.

Using the graph, what is one solution to the equation f(x) = g(x)?
Graph of function f of x equals 4 times x minus 3. Graph of function g of x equals x cubed minus x squared minus 4 times x plus 4.
x = −2.8
x = 0.5
x = 2
x = 3
Answer: 0.5
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8
g
f
)(x)=
4−5x
3x+2 f (2) = 2(2) = 4
g(2) = (2) + 4 = 6
h(2) = 5 – (2)3 = 5 – 8 = –3
Now I can evaluate the listed expressions:
(f + g)(2) = f (2) + g(2)
= 4 + 6 = 10
(h – g)(2) = h(2) – g(2)
= –3 – 6 = –9
(f × h)(2) = f (2) × h(2)
= (4)(–3)= –12
(h / g)(2) = h(2) ÷ g(2)
= –3 ÷ 6 = –0.5
Step-by-step explanation:
By looking where the functions intercept, we conclude that the correct option is x = -2.8.
What is one solution to the equation f(x) = g(x)?
Here we have:
f(x) = 4x - 3g(x) = x³ - x² - 4x + 4To find a solution of f(x) = g(x), we can graph both equations on the same axis, and see where the curves intercept.
The graph can be seen below:
There, we can see that we have intercepts at:
x = -2.8
x = 0.8
x = 2.9
From these, the only one that appears in the options is the first one, so that is the correct option.

A bag has 5 blue marbles, 1 pink marble and 2 red marbles. I draw a blue marble, put it back and draw again. What is the probability that the second marble is blue?
(A) 1/2
(B) 4/7
(C) 5/8
(D) 5/7
Answer:
C
Step-by-step explanation:
If you do 5+1+2=8 then it has to be out of 8. The only option that is out of 8 is c, and if you have 5 blue then the probability is 5 blue/8 marbles in the bag.
The probability of that second marble is blue is 5/8.
What is probability?
Probability is "possibility that deals with occurrence of random events".
According to the question,
Number of blue marbles = 5
Number of pink marbles = 1
Number of red marbles = 2
Total number of marbles = 5 + 1 + 2 = 8
Formula for Probability P(E) = [tex]\frac{Number of favourable events }{Total number of events}[/tex]
Probability of getting that second marble is blue = 5/8.
Hence, the probability of that second marble is blue is 5/8.

Answer: a
Step-by-step explanation:
The height of an acrobat who jumps from a trampoline to a large mat on the ground can be modeled by f(x)=-8x^2+16x+10, where x is the time in seconds after the acrobat jumps.
How high is the trampoline off the ground?
Find the maximum height of the acrobat and the time it takes to reach this height.
The trampoline is 10 units off the ground.
The maximum height of the acrobat is 18 units, and it takes 1 second to reach this height.
We have,
To find the height of the trampoline off the ground, we need to determine the value of f(x) when x is equal to zero.
This is because at the moment the acrobat jumps (x=0), the height of the acrobat is the height of the trampoline.
Given the function f(x) = -8x² + 16x + 10, we substitute x=0 into the function:
f(0) = -8(0)² + 16(0) + 10
f(0) = 0 + 0 + 10
f(0) = 10
Now,
To find the maximum height of the acrobat and the time it takes to reach this height, we can observe that the function f(x) is in the form of a quadratic equation in the form of ax² + bx + c, where a = -8, b = 16, and c = 10.
The maximum height of the acrobat occurs at the vertex of the quadratic function.
The x-coordinate of the vertex is given by:
x = -b / (2a)
Substituting the values, we have:
x = -16 / (2 * -8)
x = -16 / -16
x = 1
The time it takes to reach the maximum height is 1 second.
To find the maximum height, substitute the value of x back into the function:
f(1) = -8(1)² + 16(1) + 10
f(1) = -8 + 16 + 10
f(1) = 18
Therefore,
The trampoline is 10 units off the ground.
The maximum height of the acrobat is 18 units, and it takes 1 second to reach this height.

Identify the constant difference for a hyperbola with foci (−3, 0) and (3, 0) and a point on the hyperbola (7, 0).
Answer:
6
Step-by-step explanation:
By definition, the constant difference for a hyperbola is:
d = |PF1 - PF2|
where PF1 is the distance between points P and F1, and PF2 is the distance between points P and F2
Let's call F1 to (-3, 0), F2 to (3, 0) and P (7, 0). Then, the distances are:
PF1 = √[(-3 - 4)² + (0 - 0)²] = 7
PF2 = √[(3 - 4)² + (0 - 0)²] = 1
And the the constant difference is:
d = |7 - 1| = 6

1. If Salwa constructs a triangle using her protractor, and the first two
angles she constructed were 55° and 105°, what will the third angle be
when she is done?
80°
30°
20°
55
Answer: 20°
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Angle 1 = 55°
Angle 2 = 105°
The sum of the three interior angles of a triangle is always 180°.
So:
180 = 55+105 + x
Where x is the missing angle.
Solving for x:
180-55-105 =x
20°=x
