−5≤x≤34
The expression −5 ≤ x ≤ 34 is an inequality expression
How to draw the number lineThe expression is given as:
−5 ≤ x ≤ 34
This can be split as follows:
−5 ≤ x and x ≤ 34
The inequalities used in the expression are less than or equal to.
This means that the endpoints of the inequality are inclusive of the values of x.

Leila purchased a snack-size roll of candy tarts, and found that only 1/7 of them were grape-flavored. Suppose Leila later
buys a king-size roll of candy tarts that contains 40 pieces. How many of that roll can she expect to be grape-flavored?
HELP PLEASE!!!!!
Answer:
6 candy tarts
Step-by-step explanation:
Based on Leila's observations, we would expect all boxes of candy tarts to have 1/7 grape-flavoured ones. If we have a box of 40, we can find the expected number of grape flavoured nady tarts by multiplying 40 and 1/7.
40 × 1/7 = 5.714285714
You can round this to 6 candy tarts

A small rectangular package has a area of 9x square units and a height of 5 units. A large rectangular package has an area of 6 square units a d a height of 3x units more than the small box. What equation could be used to determine the volume of the large rectangular box?
The equation to determine the volume of the rectangular box is:
V = 6 * (5 + 3x)
Given that the area of the large rectangular package is 6 square units and its height is 3x units more than the small box,
To determine the volume of the large rectangular package, multiply its area by its height.
Volume of the large rectangular package = Area of the large rectangular package * Height of the large rectangular package
The area of the large rectangular package is given as 6 square units, so we substitute it into the equation:
Volume of the large rectangular package = 6 * Height of the large rectangular package
Now, the height of the large rectangular package is 3x units more than the small box. The height of the small box is 5 units, so we add 3x to it:
Height of the large rectangular package = 5 + 3x
Substituting this into the equation:
Volume of the large rectangular package = 6 * (5 + 3x)
Hence, the equation to determine the volume of the large rectangular package is: Volume = 6 * (5 + 3x)

Step-by-step explanation: have had the smae question
P is inversely proportional to q^3, when p has the value 27, q has the value 3. i) find the formula which expresses p in terms of q. P= r is directly proportional to q, when r has the value 10, q has the value 2. ii) prove that r=kp^n and so find the value of k and n.
Answer:
Step-by-step explanation:
i) If p is inversely proportional to q³, this is expressed as p ∝ q³
p = k/q³ where q is the proportionality constant.
Given p = 27 and q = 3
Substitute this values into the formula
27 = k/(3)³
27 = k/27
k = 27×27
k = 729
Substitute k = 1 into the formula
p = 729/(q)³
Hence the formula which expresses p in terms of q is p = 729/q³
ii) If r is directly proportional to q, it is expressed as r ∝ q
r = kq
If r = 10 and q = 2
Substitute
10 = 2k
k = 10/2
k = 5
The equation becomes
r = 5q... 1
From 1) p = 729/q³
q³ = 729/p
q = 9/³√p
q = 9/p^1/3....2
Substitute equation 2 into 1
r = 5(9/p^1/3)
r = 45p^-1/3
Compare r = 45p^-1/3 with r = kp^n
k = 45 and n = -1/3

Answer:
495cm
Step-by-step explanation:
so for a second forget about the already 12 meters. Multiply 15 by the amount of months, in this case 40 so 12x40= 480. Then add the 15, so its 495cm tall
If f(–2) = 0, what are all the factors of the function f (x) = x cubed minus 2 x squared minus 68 x minus 120? use the remainder theorem.
Then all factors of the function f(x) = x³ – 2x² – 68x – 120 is (x + 2), (x + 6), and (x – 10).
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
If f(–2) = 0, that mean one root is –2.
The function f(x) = x³ – 2x² – 68x – 120
We have the one factor is (x + 2)
Then the function can be written as
f(x) = (x + 2)(x² – 4x – 60)
f(x) = (x + 2)(x² – 10x + 6x – 60)
f(x) = (x + 2)[(x(x – 10) + 6(x – 10)]
f(x) = (x + 2)(x – 10)(x + 6)

Step-by-step explanation:
Our goal is to round it so we only have an integer part using the following rules:
If the first digit in the fractional part of 13.62 is less than 5 then we simply remove the fractional part to get the answer.
If the first digit in the fractional part of 13.62 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.
The first digit in the fractional part is 6 and 6 is 5 or above. Therefore, we add 1 to the integer part and remove the fractional part to get 13.62 rounded to the nearest whole number as:

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=5800(0.806)^x
Using exponential function concepts, it is found that it represents a decay of 19.4%.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the function is:
[tex]A(x) = 5800(0.806)^x[/tex]
Since the rate of change is less than 1, it is a decay.
Then:
1 - r = 0.806.
r = 1 - 0.806 = 0.194.
The function represents a decay of 19.4%.

The area of a rectangle is 54 square meters. The width is 9 meters long.
Answer:
A) [tex]9 *l=54[/tex]
Step-by-step explanation:
The area of a rectangle is w*l=A, where w is the width and l is the length.
In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.
This gives [tex]9 *l=54[/tex].Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.
This means that [tex]l=6[/tex].Rewrite in simplest terms: -2(5d-9f)+7f-10(-9f-7d)
Answer:

-2(5d-9f)+7f-10(-9f-7d
Open parenthesis
= -10d + 18f + 7f + 90f + 70d
Collect like terms
= -10d + 70d + 18f + 7f + 90f
= 60d + 115f
Factorise

Therefore,
-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )
