area of a rectangle whose length is 4x-6 and width is x+1
Answer: The area is 4x^2-2x-6
Step-by-step explanation: The area of a rectangle is length*width. So multiply both these terms. Remember the method foil, that would apply here. (4x-6)(x+1), you end up with 4x^2+4x-6x-6. Then combine like terms, to get 4x^2-2x-6.
You are buying a coke for yourself and tacos for your friends. You have a limited budget of y dollars. If the coke cost $2.25 and the tacos cost $1.25 each, write a linear inequality to help you determine how many tacos you can buy.
Answer:
2.25x+1.25y[tex]\leq[/tex]y

Step one:
given data
the budget of y dollars
the coke cost $2.25 and
the tacos cost $1.25
Required:
the linear inequality based on the limited budget
Step two:
let the number of coke be x
and the number of tacos be y
So the linear inequality is

8. Present age of Rahul and kiran are in the ratio
5:4. The ratio of their ages will be 6:5 after
5 years.Find kiran's present age.
20 years
25 years
30 years
15 years
Answer:
20 years
Step-by-step explanation:
Given the ratio of their ages = 5 : 4 = 5x : 4x ( x is a multiplier )
Then in 5 years
5x + 5 : 4x + 5 = 6 : 5 , that is
[tex]\frac{5x+5}{4x+5}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )
5(5x + 5) = 6(4x + 5) ← distribute parenthesis on both sides
25x + 25 = 24x + 30 ( subtract 24x from both sides )
x + 25 = 30 ( subtract 25 from both sides )
x = 5
Thus
Kiran's age is 4x = 4 × 5 = 20

Find the average rate of change for f(x)= x² + 3x - 6 for x₁
: 1 to 2 = 3
The average rate of change for f(x)=3x²-3 from x =1 to x=2 is 6.
What is the average rate of change?
The average rate of change is the rate at which the value of function changed per unit of independent variable over a given interval. Let f(x) be a function and value of x changes from x₁ to x₂ then rate of change of f(x) over the interval (x₁, x₂ ) is
[f(x₂)-f(x₁)]/[x₂-x₁]
Average rate of change = [f(x₂)-f(x₁)]/[x₂-x₁]
Given function is
f(x)=3x²+3x-6
x changes from 1 to 2
Then average rate of change for f(x) is [tex]\frac{f(2)-f(1))}{2-1}[/tex]
[tex]f(2)=2^{2} +3(2)-6=4+6-6\\\\f(2)=4\\f(1)=1^{2}+3(1)-6 =1+3-6\\f(1)=-2[/tex]
Average rate of change for f(x) is
[tex]\frac{f(2)-f(1))}{2-1}=\frac{4-(-2)}{2-1}\\ =\frac{6}{1}[/tex]

robert likes chocolate milk, so he decides to visit the milk bottling plant every day for a week to get the free samples. unfortunately for him, the bottling plant sometimes bottles regular milk instead of chocolate milk, so each day the plant has a 2/3 chance of bottling chocolate milk. what is the probability that the bottling plant bottles chocolate milk exactly 4 of the 5 days he visits?
The probability that the bottling plant bottles chocolate milk exactly 4 of the 5 days he visits approximately 32.9%
Probability:
Probability refers the possibility of occurring a particular event.
Binomial Probability:
Binomial probability refers the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times. The binomial is a type of distribution that has two possible outcomes.
The formula for the binomial probability is,
Pₓ = ⁿCₓ pˣ qⁿ⁻ˣ
Where,
n = the number of experiments
x = 0, 1, 2, 3, 4, …
p = Probability of success in a single experiment
q = Probability of failure in a single experiment
Given,
Robert likes chocolate milk, so he decides to visit the milk bottling plant every day for a week to get the free samples.
Unfortunately for him, the bottling plant sometimes bottles regular milk instead of chocolate milk, so each day the plant has a 2/3 chance of bottling chocolate milk.
Here we need to find the probability that the bottling plant bottles chocolate milk exactly 4 of the 5 days he visits.
Apply the values on the formula,
Then we get,
=> Pₓ=⁵C₄ x (2/3)⁴ x (1/3)
=> Pₓ = 5 x (16/81) x (1/3)
=> Pₓ = 80 / 243
=> Pₓ ≈ 32.9%

What is the equation of this line in slope intercept forn?
3z +y=2
A. y=-3+2
B. y=3z +2
C. y=-3z 2
D. y=3r-2
Answer:
We conclude that the equation of this line in the slope-intercept form will be:
[tex]y = -3z+2[/tex]Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Given the equation
[tex]3z +y=2[/tex]
Writing the equation in the slope-intercept form of the line equation by simplifying it
subtracting 3z from both sides
[tex]3z+y-3z = -3z+2[/tex]
[tex]y = -3z+2[/tex]
Therefore, we conclude that the equation of this line in the slope-intercept form will be:

An equitorial triangle has 3 medians true or false
Note: Its equilateral not equitorial triangle .
Given:
The statement is "An equilateral triangle has 3 medians".
To find:
Whether the given statement is true or false.
Solution:
Median of a triangle connected the vertex and midpoint of opposite side of the triangle.
We know that that every triangle has three medians.
In case of equilateral triangle, all sides and angles are equal and median is the height of the triangle.
So, an equilateral triangle has 3 medians.
Therefore, the given statement is true.
Tickets for a family of 6 to go skiing cost $48. whats the unit price ?
A ∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 8 x + 6 ) ∘ ∠A=(8x+6) ∘ and m ∠ B = ( 7 x + 24 ) ∘ ∠B=(7x+24) ∘ , then find the measure of ∠ B ∠B.
Answer:
< B = 94
Step-by-step explanation:
Remark
You should edit the question. The way you wrote it, , it looks like you have to square two binomials. That isn't the way it is given I don't think. You are told that A and B are supplementary. That means
A+B = 180
Equation
(8x + 6) + (7x + 24) = 180 Remove the brackets
Solution
8x + 6 + 7x + 24 = 180 Collect like terms
15x + 30 = 180 Subtract 30 from both sides
15x = 180 - 30
15x = 150 Divide by 15
x = 150 / 15
x = 10
Answer
What you need is <B
<B = 7x + 24
<B = 7*10 + 24
<B = 70 + 24
<B = 94
state whether each expression is meaningful. if not, explain why. if so, state whether it is a vector or a scalar.
The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product so options (b), (d), and (e) are not meaningful.
What is a vector?An item with both magnitude and direction is referred to be a vector.
A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.
A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.
The dot product of two vectors gives scalar quantity while the cross product gives a vector quantity.
Now,
In option (B) ;
a Х (b . c) now here b . c is a scalar quantity and we can not cross multiply a scalar with a vector.
In option (D) ;
(a.b) Χ (c.d) where we cannot multiply two scalars by cross product.
In option (E);
a.(b.c) we can not multiply two scalars by the dot product.
Hence "The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product".

The sum of the first five terms of an arithmetic sequence is 35. The sum of the next five terms is 85. Determine the first term and the common difference of the sequence.
Answer:
The first term is 3 and the common difference is 2
Step-by-step explanation:
The formula of the sum of the nth term of the arithmetic sequence is
[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex], where
a is the first termd is the common differencen is the position of the term∵ The sum of the first five terms of an arithmetic sequence is 35
∴ [tex]S_{5}[/tex] = 35
→ Substitute The values of n and S in the rule above
∵ 35 = [tex]\frac{5}{2}[2a+(5-1)d][/tex]
∴ 35 = [tex]\frac{5}{2}[2a+4d][/tex]
→ Simplify the right side
∴ 35 = 5a + 10d
→ Switch the two sides
∴ 5a + 10d = 35 ⇒ (1)
∵ The sum of the next five terms is 85
→ To find the sum of the first 10 terms add 85 to [tex]S_{5}[/tex]
∴ [tex]S_{10}[/tex] = 35 + 85 = 120
→ Substitute The values of n and S in the rule above
∵ 120 = [tex]\frac{10}{2}[2a+(10-1)d][/tex]
∴ 120 = 5[2a + 9d]
→ Simplify the right side
∴ 120 = 10a + 45d
→ Switch the two sides
∴ 10a + 45d = 120 ⇒ (2)
Now we have a system of equations to solve it and find a and d
→ Multiply equation (1) by -2
∵ -2(5a) + -2(10d) = -2(35)
∴ -10a + -20d = -70 ⇒ (3)
→ Add equations (2) and (3)
∵ (10a + -10a) + (45d + -20d) = (120 + -70)
∴ 25d = 50
→ Divide both sides by 25 to find d
∴ d = 2
→ To find a substitute d in equation (1) by 2
∵ 5a + 10(2) = 35
∴ 5a + 20 = 35
→ Subtract 20 from both sides
∵ 5a + 20 - 20 = 35 - 20
∴ 5a = 15
→ Divide both sides by 5
∴ a = 3
∴ The first term is 3 and the common difference is 2
