A moving company charges a $2,000 fee plus $100 per hour. Another moving company charges an $1,800 fee plus $150 per hour. How long is a job for which the two companies' costs are the same?
Answers
The costs of two moving companies are the same for a job that lasts 4 hours.
To find out how long a job must last for the two companies' costs to be the same, we need to set up an equation where both company costs are equal and solve for the time variable, which I will denote as 't' hours.
The first moving company's cost can be represented as:$2,000 + $100 x t.
The second moving company's cost can be represented as: $1,800 + $150 x t.
To find the time when both costs are the same, we set the two expressions equal to each other:
$2,000 + $100t = $1,800 + $150t
Now, we need to solve for 't' by subtracting $100t from both sides and subtracting $1,800 from both sides:
$200 = $50t
Divide both sides by $50 to isolate 't':
t = 4 hours
So, the two companies would have the same cost for a 4-hour job.

What are the solutions to x2 8x 7 = 0? x = –8 and x = –7 x = –7 and x = –1 x = 1 and x = 7 x = 7 and x = 8?
Answers
x² + 8x + 7 = 0
Factorize the left side.
x² + 8x + 7 = (x + 1)(x + 7)
Therefore
(x + 1)(x + 7) = 0
When (x + 1) = 0, obtain x = -1.
When (x + 7) = 0, obtain x = -7.
The solutions are x = -1 and x = -7
Answer: x = -7 and x = -1.
The correct solutions to the given equation are x = 1 and x = 7.
The solutions to the equation x² - 8x + 7 = 0 are x = 1 and x = 7.
To find these solutions, we can factor the quadratic equation by finding two numbers that multiply to 7 (the constant term) and add up to -8 (the coefficient of the x term).
Therefore, the correct solutions to the given equation are x = 1 and x = 7.

What is the area of a triangle whose vertices are
R(−4, 2),S(1, 2), and T(−5, −4)?
Enter your answer in the box
Answers
15 square units.
EXPLANATION
This triangle has one of its height(altitudes) falling outside the triangle.
We determine the base using absolute value method. This is because the coordinates of [tex]R(-4,2)[/tex] and [tex]S(1,2)[/tex] tell us that this line is horizontal. The y-values are constant.
Therefore [tex]|RS|=|1--4|[/tex]
[tex]\Rightarrow |RS|=|1+4|[/tex]
[tex]\Rightarrow |RS|=|5|[/tex]
[tex]\Rightarrow |RS|=5[/tex]
Also
The triangle is bounded between [tex]y=2[/tex] and [tex]y=-4[/tex].
Therefore the vertical height of interest,
[tex]|RT|=|-4-2|[/tex]
[tex]|RT|=|-6|[/tex]
[tex]|RT|=6[/tex]
We can now find the area using the formula
[tex]Area=\frac{1}{2}base\times height[/tex]
[tex]Area=\frac{1}{2}\times6 \times 5[/tex]
[tex]Area=3 \times 5[/tex]
[tex]Area=15[/tex] square units

What is the multiplicative rate of change of the exponential function shown on the graph?
A) 2/9
B) 1
C) 4
D) 9/2
Answers
Answer:
Option: D is correct.
9/2
Step-by-step explanation:
We have to find the multiplicative rate of change of the exponential function shown on the graph.
We know that a general exponential function is given as:
[tex]y=ab^x[/tex]
where b is the multiplicative rate of change.
Now when x=0 we have y=1.
i.e. 1=a
Hence, a=1
and y=b^x
Also,
the graph passes through (1,9/2)
Now when x=1 we have y=9/2
i.e.
9/2=b
Hence, the multiplicative rate of change is:
9/2
The correct answer is A) 2/9. The multiplicative rate of change of the exponential function shown on the graph is A) 2/9.
To determine the multiplicative rate of change of an exponential function from its graph, we need to identify two points on the graph that are one unit apart horizontally (i.e., one unit apart in the x-direction). The multiplicative rate of change is the ratio of the function values (y-values) of these two points.
Let's assume we have two points, (x, y) and (x+1, y'), where y and y' are the corresponding y-values of the exponential function at these x-values. The multiplicative rate of change, r, is given by:
[tex]\[ r = \frac{y'}{y} \][/tex]
From the graph, we can identify two such points. For example, if the function passes through the y-axis at (0, 1) and then at (1, 2/9), we can calculate the multiplicative rate of change as follows:
[tex]\[ r = \frac{2/9}{1} = \frac{2}{9} \][/tex]
This is the multiplicative rate of change of the exponential function. It indicates that for every unit increase in x, the y-value is multiplied by 2/9.
Therefore, the multiplicative rate of change of the exponential function shown on the graph is A) 2/9.

What is the perimeter of a square with an area of 144 square inches?
Answers
Since we know a square has sides of equal length, and to find the area of a square you square one of the side lengths, find the square root of 144.
The square root of 144 is 12.
So the means each side length is 12.
A perimeter is the distance around the square, or all of the side lengths added together.
4 sides on a square, each length is 12...
12 x 4 = 48
The perimeter is 48

What is the solution to the following system of linear equations?
{4x - y = -6
{x - 2y = -5
Please explain how you solved!
Answers
Final answer:
The solution to the system of linear equations is x = -1, y = 2
Explanation:
To solve the system of linear equations:
4x - y = -6
x - 2y = -5
We can use the method of substitution or elimination to find the solution.
Let's use the elimination method. We can multiply the second equation by 4 to make the coefficients of x in both equations the same.
4(x - 2y) = 4(-5)
4x - 8y = -20
Now, we can subtract the second equation from the first equation to eliminate x.
(4x - y) - (4x - 8y) = (-6) - (-20)
-y + 8y = 14
7y = 14
y = 2
Substituting y = 2 back into the first equation:
4x - 2 = -6
4x = -4
x = -1
The solution to the system of linear equations is x = -1, y = 2

Plz help me ASAP and show all of the steps that you did! PLEASE HELP!!! :) 10 POINTS!!!!!
Answers
If that assumption is correct, then we do two things to solve for t. First, we multiply both sides by 16. This undoes the division of 16 on the left side
[tex]\frac{5}{16}t = -9[/tex]
[tex]16*\frac{5}{16}t = 16*(-9)[/tex]
[tex]5t = -144[/tex]
-------------------------------
Then we divide both sides by 5 to undo the multiplication of 5 (note: 5t means 5*t or "5 times t")
[tex]5t = -144[/tex]
[tex]\frac{5t}{5} = \frac{-144}{5}[/tex]
[tex]t = -\frac{144}{5}[/tex]
-------------------------------
So here's what all the steps look like:
[tex]\frac{5}{16}t = -9[/tex]
[tex]16*\frac{5}{16}t = 16*(-9)[/tex]
[tex]5t = -144[/tex]
[tex]\frac{5t}{5} = \frac{-144}{5}[/tex]
[tex]t = -\frac{144}{5}[/tex]
note: -144/5 converts to the decimal value of -28.8 so t = -144/5 is the same as t = -28.8

There are five position players on a starting basketball team: 2 guards, 2 forwards, 1 canter. Write a ratio in simplest from to express each relationship
Answers
Final answer:
The ratios for the basketball positions in simplest form are guards as 2:5, forwards as 2:5, and the center as 1:5.
Explanation:
The question asks to write ratios for the positions on a basketball team and then to express those ratios in simplest form. There are 5 position players on a starting basketball team, consisting of 2 guards, 2 forwards, and 1 center. To express the relationships between each position, we can write the ratios of guards to the total number of players, forwards to the total number of players, and the center to the total number of players.
The ratio of guards to the total number of players is 2 guards to 5 total players, which simplifies to 2:5.
The ratio of forwards to the total number of players is 2 forwards to 5 total players, simplifying to 2:5.
Lastly, the ratio of the center to the total number of players is 1 center to 5 total players, simplified as 1:5.

how do you solve this absolute value equation? ∣x−2∣=∣4+x∣
Answers
Remember : Absolute is just the distance from zero.
Ex : l -4 l turns into 4, as it is 4 spaces away from zero on a number line :)
l x - 2 l turns into x + 2
l 4 + x l stays the same.
So, our equation now looks like this :
x + 2 = 4 + x
So, we're basically just trying to get x by itself.
So, subtract 2 from both sides.
x = 4 + x - 2
Then, subtract x from both sides.
x - x = 4 -2
0 = 2
Therefore, there are no solutions to this equation :)
