Write the equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right.
a) g(x) = x + 3
b) g(x) = x + 8
c) g(x) = x − 8
d_ g(x) = x + 2
Answer:
[tex]g(x) = x + 2[/tex]
Step-by-step explanation:
Parent function [tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
If f(x) is shifted 'a' units to the right then f(x) becomes f(x-a)
If f(x) is shifted 'a' units to the left then f(x) becomes f(x+a)
[tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
Then we subtract 3 from x
So , [tex]f(x) = x + 5[/tex] becomes [tex]f(x-3) = x-3 + 5=x+2[/tex]
[tex]g(x) = x + 2[/tex]
The equation of function will be;
g (x) = x + 2
Option d is true.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
Parent function, f(x) = x + 5 is shifted 3 units to the right.
Since, If a function f(x) is shifted 'a' units to the right then function f(x) becomes f(x-a).
So, The equation of function will be calculated as;
The parent function is shifted 3 units to the right.
Then, we subtract 3 as;
g (x) = x + 5 - 3
g (x) = x + 2
Thus, The equation of function will be;
g (x) = x + 2

Which number sentence is TRUE?
A. 3 ÷ 1 < 0 ÷ 3
B. 0 ÷ 3 > 3 ÷ 3
C. 3 ÷ 1 > 3 ÷ 3
D. 3 ÷ 3 < 4 ÷ 4
The correct option is C. 3 ÷ 1 > 3 ÷ 3.
To solve this problem, we need to evaluate each of the given number sentences to determine which one is true.
A. 3 ÷ 1 < 0 ÷ 3
First, we perform the divisions:
3 ÷ 1 = 3
0 ÷ 3 = 0
Now we compare the results:
3 < 0
This statement is false because 3 is not less than 0.
B. 0 ÷ 3 > 3 ÷ 3
Again, we perform the divisions:
0 ÷ 3 = 0
3 ÷ 3 = 1
Now we compare the results:
0 > 1
This statement is false because 0 is not greater than 1.
C. 3 ÷ 1 > 3 ÷ 3
We perform the divisions:
3 ÷ 1 = 3
3 ÷ 3 = 1
Now we compare the results:
3 > 1
This statement is true because 3 is greater than 1.
D. 3 ÷ 3 < 4 ÷ 4
We perform the divisions:
3 ÷ 3 = 1
4 ÷ 4 = 1
Now we compare the results:
1 < 1
This statement is false because 1 is not less than 1; they are equal.
Therefore, the only true statement is C. 3 ÷ 1 > 3 ÷ 3.
Round 503.782 to the nearest tenth
The value 503.782 to the nearest tenth is 503.8
Rounding up to the nearest tenth means we want only a digit to be placed after the decimal point.
Given the value 503.782, this value to the nearest tenth will be 503.8.
Note that 1 was added to the value "7" after the decimal point. This was because the adjacent value "8" is more than 4.
Hence the value 503.782 to the nearest tenth is 503.8
Learn more here: https://brainly.com/question/21028116
Final answer:
To round 503.782 to the nearest tenth, the digit in the hundredths place is 8, which is greater than or equal to 5. Therefore, the rounded number is 503.8.
Explanation:
To adjust 503.782 to the closest 10th, we really want to take a gander at the digit in the hundredths place, which is the second digit after the decimal point. It is 7 in this instance.
Since 7 is more prominent than or equivalent to 5, we gather together the digit in the tenths place, which is the primary digit after the decimal point. For this situation, it is 8.
Therefore, 503.8 is obtained by rounding 503.782 to the nearest tenth.
To round 503.782 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, the rounded number is 503.8.

an electrician charges $322 for 7 hours of work. how much does the electrician charge per hour?
Answer:
The electrician charges $46 per hour
Step-by-step explanation:
we know that
An electrician charges $322 for 7 hours of work
so
using proportion
Find out how much does the electrician charge per hour
Let
x ----> the charge per hour
[tex]\frac{322}{7}\frac{\$}{h}=\frac{x}{1}\frac{\$}{h}\\\\x=322/7\\\\x=\$46[/tex]
therefore
The electrician charges $46 per hour
The electrician charges $46 per hour.
The total charge is $322, and the total number of hours worked is 7.
To find the charge per hour, use the formula:
Charge per hour = Total charge / Number of hours
Substitute the given values into the formula:
Charge per hour = 322 / 7
Perform the division:
322 divided by 7 equals 46. Therefore, the electrician charges $46 per hour.
So, the calculation is:
Charge per hour = 46

Consider the cubic function f(x) = x^3 + ax^2 + bx + 4 where (a) and (b) are constants. When f(x) is divided by x-3, the remainder is 10. When f (x) is divided by x+1, the remainder is 6.
Show that a = -1 and b = -4
Answer:
see explanation
Step-by-step explanation:
Using the Remainder theorem
If f(x) is divided by (x - h) then f(h) = remainder, thus
f(3) = 3³ + a(3)² + b(3) + 4 = 10, that is
27 + 9a + 3b + 4 = 10
9a + 3b + 31 = 10 ( subtract 31 from both sides )
9a + 3b = - 21 → (1)
f(- 1) = (- 1)³ + a(- 1)² + b(- 1) + 4 = 6, that is
- 1 + a - b + 4 = 6
a - b + 3 = 6 ( subtract 3 from both sides )
a - b = 3 → (2)
Rearrange (2) expressing a in terms of b
a = 3 + b → (3)
Substitute a = 3 + b into (1)
9(3 + b) + 3b = - 21 ← distribute and simplify left side
27 + 9b + 3b = - 21
12b + 27 = - 21 ( subtract 27 from both sides )
12b = - 48 ( divide both sides by 12 )
b = - 4
Substitute b = - 4 into (3)
a = 3 - 4 = - 1
Hence a = - 1 and b = - 4

Answer: 7/12
Step-by-step explanation:
Answer:
7/12
Step-by-step explanation:
The problem is asking us to find what fraction of students watch between 0 and 2 hours of TV a day:
The information we have is:
0 - 1 hours = 1/6
1 1/2 - 2 hours = 5/12
We only need this information because it is asking us for 0 to 2 hours.
Now we have to add the fraction of students that watch TV 0-1 hours and the fraction of students watch TV 1 1/2 - 2 hours:
1/6 + 5/12
To be able to solve this we have to have the same denominator and to do it we have to multiply the first fraction by 2:
(1/6) *2 = 2/12
Now we can add:
2/12 + 5/12 = 7/12
We add the numerators and the denominator stays the same.

If the trip takes 3 hours for a total distance of 350 km, travelling at x hours at 120km/h and remaining time at 60 km/h
Answer:
x = 2.8 hours
Explanation
Total distance = 350 km
Time period = 3 hrs
Hence we need to formulate an equation...,
Distance = Speed × Time
; Distance covered travelling at 120 = 120x Since the total time period was 3hrs...then the remaining time is (3 - x)
;Distance covered travelling at 60 = 60(3- x)
The equation is going to be...,
; 120x + 60(3 - x) = 350...since total distance is 350 km
; 120x + 180 - 60x = 350
; 60x = 170....divide both sides by 60
Hence..., x = 2.8 hours

C. Cubic expression
D. Exponential expression
The expression [tex]\(5x + 2x - 3\)[/tex] is a linear expression.
The expression [tex]\(5x + 2x - 3\)[/tex] represents a linear expression because it consists of terms involving only the variable \(x\) raised to the power of 1. In other words, each term is a linear term.
Linear expressions depict relationships that are straight lines when graphed on a Cartesian plane. In this case, \(5x\) and \(2x\) are both linear terms since they involve the variable \(x\) raised to the first power, while the constant term \(-3\) does not involve \(x\) at all.
The expression simplifies to [tex]\(7x - 3\),[/tex] maintaining its linear form. Linear expressions are fundamental in algebra and represent relationships with constant rates of change.

The required, 5.241 divided by 3 equals approximately 1.747.
To divide 5.241 by 3, we can perform the division as follows:
1.747
------------
3 | 5.241
To start, we divide the whole number part, 5, by 3. The result is 1, which becomes the whole number part of the quotient.
Next, we bring down the decimal point and consider the decimal part of the dividend, which is 0.241. We can continue the division process by adding a decimal point to the quotient and placing a 0 to the right of the decimal point.
1.747
3 | 5.241
- 3
-----
24
Now, we divide 24 by 3, which gives us 8. We bring down the next decimal digit, which is 1, and continue the division:
1.747
3 | 5.241
- 3
-----
24
- 24
-----
1
Since there are no more decimal digits to bring down, we have finished the division. The final quotient is 1.747, rounded to three decimal places.
Therefore, 5.241 divided by 3 equals approximately 1.747.

A manufacturing company produced 1,800 vehicle.of those 30% were trucks 25% were sports cars, and 10% were vans. How many of the vehicle were not trucks,sports cars, or vans ?
Answer:
630
Step-by-step explanation:
if you add the percentages of the trucks, sport cars and vans you get:
30% + 25% + 10% = 65%. So to find the percentage of vehicles that aren't in this categories you substract this percentage from 100%.
100% - 65% = 35%
This means that 35% of the vehicles aren't in those categories, so to find the amount you just multiply the total of vehicles with the percentage an then divide by 100
(1,800*35)/100 = 630 vehicles
