write the algebraic expression for the verbal statement. Let x represent the unknown number. 3 less than twice the sum of a number and 4
The algebraic expression for '3 less than twice the sum of a number and 4' where x is the unknown number is
'2(x + 4) - 3'.
The algebraic expression for the verbal statement "3 less than twice the sum of a number and 4" can be written as follows:
First, let's represent the unknown number by x. The phrase 'the sum of a number and 4' translates to x + 4. 'Twice this sum' means we multiply the expression by 2, resulting in 2(x + 4). Finally, '3 less than' indicates that we need to subtract 3 from this expression. Therefore, the complete algebraic expression is 2(x + 4) - 3.

1)The range of the following relation: R {(3, -5), (1, 2), (-1, -4), (-1, 2)} is
{-1, 1, 3}
{-5, -4, 2}
{-1, -1, 1, 3}
{-4, -5, 2, 2}
2) The domain of the following relation: R {(3, -2), (1, 2), (-1, -4), (-1, 2)} is
{-1, 1, 3}
{-1, -1, 1, 3}
{-4, -2, 2, 2}
{-4, -2, 2}
The range of the first relation is {-5, -4, 2}, and the domain of the second relation is {-1, 1, 3}.
The range of a relation is the set of all second elements in each ordered pair. For the relation R = {(3, -5), (1, 2), (-1, -4), (-1, 2)}, the range is the set of second elements {-5, 2, -4, 2}. When we list the unique values, we get the range as {-5,-4, 2}.
The domain of a relation consists of all the first elements in each ordered pair. Given the relation R = {(3, -2), (1, 2), (-1, -4), (-1, 2)}, the domain is the set of first elements {3, 1, -1, -1}. The domain with unique values is {-1, 1, 3}.
what is the value of x in the equation -6/7= -×/84?
Answer:
x=7.
Step-by-step explanation:
To solve this you just hace to clear x from the equation and multipliead the other part of the equation by -84:
[tex]\frac{-6}{7} =\frac{-x}{84} \\x=\frac{6*-84}{7} \\x=\frac{504}{7}\\ x= 72[/tex]
So we know that the value of x in the equation will be 72,

Gary is buying a $1,250 computer on the installment plan you makes a down payment on of $150 she has to make monthly payments of $48.25 for two and a half years what is the finance change
Answer:
$347.6
Step-by-step explanation:
The computer cost $1250. If Gary made a down paymnet of $150, $1100 is left to be paid. The financial cost per month is $48.25. For two and a half years this amount must be multiplied by the number of months. In two and a half years there is:
[tex]=12+12g+6=30[/tex]
30 months. Gary pays
[tex]=30\cdot{48.25}=1447.5[/tex]
$1447.5 for 30 months. The original amount was $1250. Cary pays a total of:
[tex]=150+1447.6=1597.6[/tex]
The financial change is:
[tex]1597.6-1250=347.6[/tex]

Ruth sets out to visit her friend ward, who lives 20 mi north and 100 mi east of her. she starts by driving east, but after 70 mi she comes to a detour that takes her 15 mi south before going east again. she then drives east for 8 mi and runs out of gas, so ward flies there in his small plane to get her.
Solution:
Distance between Ruth House and Ruth Friend House =20 Meter north and 100 meter east of Ruth
Now , Ruth Starts Driving,
but after 70 mi she comes to a detour that takes her 15 mi south before going east again. she then drives east for 8 mi and runs out of gas.
The Diagram of Ruth Driving is depicted below.
Now , when ward flies in small plane to get Ruth,
So, Distance between Ruth and Ward , when Ruth is at Point S=SM
In Right Δ SVM, By Using Pythagoras theorem
SM²=SV² + VM²
DT=VS=15 m
VM=100 - (70+8)
= 100 -78
=22 meter
SM²=(15)² + (22)²
= 225 + 484
= 709
[tex]SM=\sqrt{709}=26.62[/tex]
So, Ward has to travel 26.62 miles east north to reach Ruth.
There are 8 people fishing at Lake Connor: 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. What is the probability that the first person chosen has a license and the second one does not? Write your answer as a fraction in simplest form.
Answer:3/28
Step-by-step explanation:
The probability that the first person chosen has a license and the second one does not is 15/56
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, there are 8 people fishing at lake 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. we need to find the probability that the first person chosen has a license and the second one does not
Let us consider the possibility of the first person not having a license, which is:
3/7
Now, after a person has been chosen, there will be 7 people remaining. Assuming that the first person chosen did not have a license, there will be 2 people left in the group without a license.
So, the probability of choosing a person without a license the second time will be:
3/7
In probability, when two events occur together (the word "and" is used), multiplication is carried out.
Therefore, we multiply the two probabilities to get:
5/8 x 3/7 = 15/56
Hence, The probability of choosing two people without a license is 15/56

Find a formula for a function of the form y=bxe^−ax with local maximum at (1,2.2073). y=________
The required formula is y = 6x e⁻ˣ for a function of the form y=bxe^−ax with the local maximum at (1,2.2073).
What are Maxima of a Function?A function curve has peaks known as maxima. There can be an unlimited number of peaks.
The given function of the form as:
y = bxe⁻ᵃˣ y' = be⁻ᵃˣ (1-ax)
Plug point (x,y) = (1, 2.2073) into equation: 2.2073 = 6be⁻ᵃ
Now plug in y' = 0 at the same x value: 0 = be-6ᵃ(1-6a) or a = 1
and y' = be⁻ᵃ(-a + 1) = 0 giving a = 1
From first equation 2.2073 = b e⁻¹ so b = 2.2073e = 6
So the required formula is y = 6x e⁻ˣ
To find b, plug an into the first equation. The sign of the first derivative shifts from + to -, indicating that it is a maximum critical point.
You may graph the equation using your constants and observe that the point (1, 2.2073) is the maximum.
Therefore, the required formula is y = 6x e⁻ˣ.

what is 5-2y=3x in standard form?
To write 5 - 2y = 3x in standard form, you rearrange it to Ax + By = C, resulting in the equation 3x - 2y = -5, which is in standard form as requested.
To write the equation 5 - 2y = 3x in standard form, you want to arrange it to Ax + By = C, where A, B, and C are integers, and A should not be negative. Here's how you can do it:
First, we will move the term involving x to the left side of the equation by subtracting 3x from both sides:3x - (5 - 2y) = 3x - 3xThis simplifies to:-3x + 2y = 5Finally, to keep A positive, if necessary, multiply the entire equation by -1:3x - 2y = -5Thus, the standard form of the equation is 3x - 2y = -5.
