Jim’s new car has 150 miles on the odometer. He takes a trip and drives an average of m miles each day for three weeks. Which expression represents the mileage on Jim’s car after his trip?
Answer:
[tex](150+21m)\ miles[/tex]
Step-by-step explanation:
we know that
[tex]1\ week=7\ days[/tex]
Remember that the speed is equal to divide the distance by the time
Let
s ---> the speed in miles per day
d ---> the distance in miles
t ---> the time in days
[tex]s=\frac{d}{t}[/tex]
[tex]d=st[/tex]
we have
[tex]s=m\ miles/day[/tex]
[tex]t=3\ weeks[/tex]
Convert to days
[tex]t=3(7)=21\ days[/tex]
Find the distance covered in the trip
[tex]d=st[/tex] ----> [tex]d=m(21)=21m\ miles[/tex]
To find out the mileage on Jim’s car after his trip, sum the mileage before his trip (150 miles) plus the mileage of the trip
[tex](150+21m)\ miles[/tex]
What is 8.4 x 10^12/4.2 x 10^6
Answer:
2 × [tex]10^{6}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]\frac{a^{m} }{a^{n} }[/tex] ⇔ [tex]a^{(m-n)}[/tex]
Split the fraction into a product, that is
= [tex]\frac{8.4}{4.2}[/tex] × [tex]\frac{10^{12} }{10^{6} }[/tex]
= 2 × [tex]10^{(12-6)}[/tex]
= 2 × [tex]10^{6}[/tex]

The graphs below have the same shape. What is the equation of the blue graph?
Answer:
Option C. [tex]g(x)=(x+5)^{2}[/tex]
Step-by-step explanation:
we know that
The equation of the parent function f(x) (red graph) is
[tex]f(x)=x^{2}[/tex]
This is a vertical parabola open upward
The vertex is the point (0,0) (the origin)
The function g(x) (blue graph) is a vertical parabola open upward
The vertex is the point (-5,0)
The transformation of f(x) to g(x) has the following rule
f(x) -----> g(x)
(0,0) ----> (-5,0)
(x,y) ----> (x-5,y)
That means----> The transformation is a translation of 5 units at left
therefore
The equation of g(x) is
[tex]g(x)=(x+5)^{2}[/tex]
Which three comparisons are true?
1/2 = 2/4
6/8 = 1/4
3/6 = 2/4
2/4 = 4/6
4/8 = 2/4
Answer:
The answer is 4/8=2/4 because 4/8 simplifying is 2/4 or 1/2
The true fraction comparisons are 1/2 = 2/4 and 4/8 = 2/4. The other comparisons are false. Simplifying fractions helps determine their equality.
Comparing Fractions:
Let's determine which of the given fraction comparisons are true:
1/2 = 2/4: To check this, we can simplify 2/4. Dividing both the numerator and the denominator by 2, we get 1/2. Thus, 1/2 equals 2/4. This is a true statement.6/8 = 1/4: We simplify 6/8 by dividing both the numerator and the denominator by 2, which gives us 3/4. This does not equal 1/4. This is a false statement.3/6 = 2/4: Simplifying 3/6 by dividing both the numerator and the denominator by 3, we get 1/2. Simplifying 2/4 gives us 1/2 as well. Therefore, 3/6 equals 2/4. This is a true statement.2/4 = 4/6: Simplifying 2/4 to 1/2 and simplifying 4/6 to 2/3 shows that 2/4 does not equal 4/6. This is a false statement.4/8 = 2/4: Simplifying 4/8 by dividing both the numerator and the denominator by 4, we get 1/2. Simplifying 2/4 also gives us 1/2. Thus, 4/8 equals 2/4. This is a true statement.The three true comparisons are: 1/2 = 2/4, 3/6 = 2/4, 4/8 = 2/4, and none from the rest.

The black graph is the graph of y=f(x). Choose the equation for the red graph.
Please help!!!
Answer:
C
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x) by c units
• If c > 0 then shift c units up
• If c < 0 then shift c units down
The red graph is a vertical translation f(x) of 3 units down
Thus
y = f(x) - 3 ( add 3 to both sides )
y + 3 = f(x) ← equation of red graph
Help me please with question 4 b
Answer:
see explanation
Step-by-step explanation:
The second term of sequence P is 2a + b
The third term of sequence Q is 3b + a
Equating gives
2a + b = 3b + a ( subtract a from both sides )
a + b = 3b ( subtract b from both sides )
a = 2b ← as required
Good evening ,
Step-by-step explanation:
4 (b)
The 2nd term of sequence P is 2a+b
The 3rd term of sequence Q is 3b+a
2a+b=3b+a ⇌ (2a-a) = (3b-b) ⇌ a=2b.

. In an encyclopedia of language, the author presents five sentences that make a reasonable paragraph regardless of their order. The sentences are listed below. Mark had told him about the foxes. John looked out of the window. Could it be a fox? However, nobody had seen one for months. He thought he saw a shape in the bushes. In how many different orders can the five sentences be arranged?
Answer:
the 1st & last paras are fixed.
that leaves 3 to be put in any order
there are 3 choices for the 1st,
2 choices left for the 2nd
and just 1 choice for the last
multiply to get
3*2*1
= 6 ways
We want to find the total number of orders in which we can order the given sentences.
We will see that there are 120 different orders.
There are 5 sentences, let's define them as:
s₁ = Mark had told him about the foxes.s₂ = John looked out of the window.s₃ = Could it be a fox? s₄ = However, nobody had seen one for months.s₅ = He thought he saw a shape in the bushes.We know that we can order these in any order, so we can think of the situation as 5 empty slots, in each slot, we can put one of the previous statements.
Let's count the number of options for each one of these slots.
On the first one, we have 5 options (5 sentences)
On the second one we have 4, because we already used one on the first slot.
On the third, we have 3 options.
On the fourth, we have 2 options.
On the fifth, we have 1 option.
The total number of combinations is given by the product of these numbers of options.
Combinations = 5*4*3*2*1 = 120

A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $100 each day to operate the bank and $50 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most: 50x + 100 ≤ 600
Answer:
The restaurant Manager can afford 6 employees for the day.
Step-by-step explanation:
Manager can spend at most of $400.
Total Money ≤ $400
Cost to operate bank = $100
Cost for each employee = $50
Let number of employees for the day be[tex]x[/tex]
Hence the equation will become;
[tex]50x + 100 \leq 400[/tex]
Solving this equation we get;
[tex]50x + 100 \leq 400\\50x \leq 400-100\\50x \leq 300\\x\leq \frac{300}{50}\\\\x\leq 6[/tex]
Hence, The restaurant Manager can afford 6 employees for the day.

14) What is the graph of the function rule ?
y= |2x|-1
Because the equation contains an absolute value, the shape of the graph would be a V,.
The Y intercept is -1, so this would be the lowest point on the graph.
Replace X with 1 and solve:
y = 2(1) -1 = 2-1 = 1, so another point would be (1,1) and another point would be (-1,1) ( Absolute value would use both -1 and 1 as the same).
Make 3 points on the graph:
(-1,1) (1,1) ans (0,-1) and draw lines through them.

10. |-41|
12. -|1.5|
Step-by-step explanation:
10. |-41|= 41
12. -|1.5|= -1.5
Answer:
A.) 41
B.) -1.5
Step-by-step explanation:
Absolute value means to make whatever that is inside positive
10.) The absolute value of negative 41 would simply be positive 41
11.) Since the negative sign is on the outside of the absolute value, you do the absolute value of everything inside then apply a negative sign. Absolute value of 1.5 is just 1.5 because it's already positive. Then apply the negative sign, which would make it -1.5

Formulate the recursive formula for the following geometric sequence.
{-16, 4, -1, ...} Show all your work please:)
The recursive formula for given sequence is:
[tex]a_n = -\frac{1}{4}a_{n-1}[/tex]
Step-by-step explanation:
Given sequence is:
-16, 4, -1, ...
First of all, we have to find the common ratio. common ratio is the ratio between two consecutive terms of a geometric sequence
Here
[tex]a_1 = -16\\a_2 = 4\\a_3 = -1\\Now\\r = \frac{a_2}{a_1} = \frac{4}{-16} = -\frac{1}{4}\\r = \frac{a_3}{a_2} = \frac{-1}{4} = -\frac{1}{4}[/tex]
The recursive of geometric sequence is:
[tex]a_n = r * a_{n-1}[/tex]
Putting the value of r
[tex]a_n = -\frac{1}{4}a_{n-1}[/tex]
Hence,

Amit built a sand castle that measured 600 centimeters by 600 centimeters, and dug a moat around it.
Afterward, he decided to change the castle size, making it 8 meters by 6 meters.
How much longer will the new moat be than the old one?
Answer:
4 meters longer.
Step-by-step explanation:
Amit built a sandcastle that measured 600 cm by 600 cm i.e. 6 meters by 6 meters.
Therefore, its perimeter is 2(6 + 6) = 24 meters
Now, afterward, he decided to change the castle size, making it 8 meters by 6 meters.
Therefore, its perimeter is 2(6 + 8) = 28 meters
Therefore, the perimeter of the new castle is increased by (28 - 24) = 4 meters.
If Amit dug a moat around his castle then the new moat will be 4 meters longer than the old one. (Answer)
As the moat is dug around the castle, its length will be the same as the perimeter of the castle.

3x - By = 7
x +2y = -7
x = - 3
y = -2
Step-by-step explanation:
3x - 8y = 7
x +2y = -7
We standardize the coefficient of one variable such that it addition will result to zero;
3x - 8y = 7
(x +2y = -7)4
Then multiply the one equation with a constant (this case 4) to get;
3x – 8y = 7
4x + 8y = - 28
We add the two equations;
3x – 8y = 7
+
4x + 8y = - 28
=
7x = - 21
x = -21 / 7
x = - 3
Now we evaluate y by replacing the value of x with -4 in one of the equation;
x +2y = -7
-3 +2y = -7
2y = -7 + 3
2y = - 4
y = -2
