How many solutions does this system have?
y=5x-1
y=-3x+7
Answer:
One solution
Step-by-step explanation:
We have the system
[tex]y=5x-1\\y=-3x+7[/tex]
To solve the system, equate both equations and solve for the variable x.
[tex]5x-1= -3x+7\\\\5x + 3x = 7 +1\\\\8x = 8\\\\x=1[/tex]
Now substitute the value of x in any of the two equations and solve for the variable y.

A girl had $12 but spent $3 of it . what per cent did she spend
Answer:
She spent 25%
Hello There!
The girl spent 1/4 of her money. 12 is divisible by 3 and when we divide, we get a quotient of 3
If the girl spent $3, we subtract 3 from 12 and we see that 3 = 1/4 6=2/4 and 9=3/4 but if she spent $3 it would be 1/4
The Girl Spent 1/4 of her money. This is also known as 25%

Answer:
The total cost of the tent with the markup and then tax applied is $409.86
Step-by-step explanation:
230 is the original
the price is going to increase by 230(.65)=149.5
So the new price is 230+149.5=379.5 (this is before tax is applied)
The sales tax is 8% or .08
So the price is going to increase by .08(379.5)=30.36 (this is the tax to add in)
So the total cost is 379.5+30.36=409.86
Answer:
Cost of the tent: $517.86
Step-by-step explanation:
Since it's marked up by 65%, that means you add an additional $149.59 to $230. Now, you have $479.50. Now with 8% tax, you multiply $479.50 to 0.08 and we get $38.36. We add $38.36 to $479.50 and we get $517.86. I hope this helps and please mark me brainliest!

30Step by-step explanation:just took the testMiles paid $5824, including 4% sales tax, for an out-of-state purchase of a car. In order to calculate the amount of sales tax he owes in his state, he must first determine the price of the car without sales tax. How much did the car cost before sales tax? This one is a little bit tricky. The amount you need to find the sales tax of is not know. Let the original price be x. Then, 4% of that price is 0.04x. Adding the original price and the sales tax, we get the amount paid. Therefore, the equation is
X + 0.04x = 5824
Answer:
$5600
Step-by-step explanation:
Original Cost = x
Total Cost = $5824
Sales Tax = 4% or 0.04
Problem Setup
(Original Cost) + 4% (Original Cost) = Total Cost
x + 0.04x = 5824
1x+ 0.04x = 5824
1.04x = 5824
1.04x/1.04 = 5824/1.04
x=5600 Original Cost
To Check math multiply 5600 x 0.04 = 224.
Then add $5600 + $224 = $5824
The price of the car before sales tax is $5600.
To determine the cost of the car before sales tax, we can use the equation provided:
[tex]x + 0.04x = 5824[/tex]
Here, [tex]x[/tex] represents the original price of the car before sales tax, and [tex]0.04x[/tex] represents the amount of sales tax, which is 4% of the car's price.
First, combine the terms on the left side of the equation:
[tex]1x + 0.04x = 1.04x[/tex]
Therefore, the equation simplifies to:
[tex]1.04x = 5824[/tex]
Next, to solve for [tex]x[/tex], divide both sides of the equation by 1.04:
[tex]x = \frac{5824}{1.04}[/tex]
Calculating the right side:
[tex]x = 5600[/tex]
NEED ANSWER NOW A team is selling discount cards as a fundraiser. The table shows the number of cards sold and the remaining amount of money needed. Which word describes the slope of the line representing the data in the table? zero undefined negative
This question is based on the reasoning. Therefore, the negative slope of the line representing the data in the table.
Given;
A team is selling discount cards as a fundraiser. The table shows the number of cards sold and the remaining amount of money needed.
We have to describe the slope of the line representing the data in the table.
Reasoning: The number of cards sold is represented by x-axis and the amount of money needed is represented by the y-axis.
In general, as we sell more cards, we gain more money and then, the amount of money needed goes down.
From the given graph terms, we start at the top of our graph with the amount of money needed and zero cards sold and then as we sell cards your slope of the line goes down and we need less and less money.
Therefore, the negative slope of the line representing the data in the table.

int(1 \(1 + {e}^{x} )
Answer:
[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx}= x - \ln(1 + e^{x}) + C\end{aligned}[/tex].
Step-by-step explanation:
The first derivative of the denominator [tex]1 + e^{x}[/tex] is [tex]e^{x}[/tex]. Rewrite the fraction to obtain that expression on the numerator.
[tex]\begin{aligned}\frac{1}{1 + e^{x}} &= \frac{1 + e^{x}}{1 + e^{x}} - \frac{e^{x}}{1+e^{x}}\\&=1-\frac{e^{x}}{1+e^{x}}\end{aligned}[/tex].
In other words,
[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx} &= \int{dx} - \int{\frac{e^{x}}{1+e^{x}}\cdot dx}\end{aligned}[/tex].
Apply [tex]u[/tex]-substitution on the integral [tex]\displaystyle \int{\frac{e^{x}}{1+e^{x}}\cdot dx}[/tex]:
Let [tex]u = 1 + e^{x}[/tex]. [tex]u > 1[/tex].
[tex]du = e^{x}\cdot dx[/tex].
[tex]\displaystyle \int{\frac{e^{x}}{1+e^{x}}\cdot dx} = \int{\frac{du}{u}} = \ln{|u|} = \ln{u} +C = \ln{(1+e^{x})}+C[/tex].
Therefore
[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx} &= \int{dx} - \int{\frac{e^{x}}{1+e^{x}}\cdot dx}\\ & = x - \ln{(1 + e^{x})}+C\end{aligned}[/tex].

No c
as she was initially 300m away from the bridge (distance from bridge=300m) (time=0) so it was her starting point.
and after 6 minutes (time=6min) she reached the bridge. (distance from bridge = 0m)
Answer:
C.Katy was initially 300 meters away from the bridge and it tooke her 6 minutes to reach the bridge.
Step-by-step explanation:
As you can see in the table when Katy had been walking for 0 minutes, she was 300 meters away, so initially Katy was 300 meters from the bridge.
When she reaches the bridge is when the distance is reduced to 0, since distances is reduced to 0 at 6 minutes, we can infer that it took her 6 minutes to reach the bridge, and that se was walking at a pace of 50 meters per minute.

4x^2+4x+1=9 solutions
Answer:
x = - 2, x = 1
Step-by-step explanation:
Given
4x² + 4x + 1 = 9 ( subtract 9 from both sides )
4x² + 4x - 8 = 0 ← in standard form
Divide through by 4
x² + x - 2 = 0
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1

On Monday, the temperature was 6 degrees cooler than it had been on Sunday, on Tuesday the temperature rose 4 degrees from Monday. Wednesday's temperature was cooler than Tuesday's, but not as cool as it was on Monday. Which answer choice shows a reasonable answer for the difference in temperature on Wednesday, as compared to the temperature on Sunday?
A) -10 degrees
B) -7 degrees
C) -4 degrees
D) -2 degrees
Answer:
C) -4 degrees
Step-by-step explanation:
let's set Sunday Temp = 0°
Since Monday is 6° cooler than Sunday, we subtract 6° from 0 (Sunday's temp)
Monday's Temp -6 (0-6)
Since Tuesday's Temp is 4° higher than Monday, we add 4 to Monday's temp:
Tuesday's Temp -2 (-6+4)
Wednesday's Temp is cooler than Tuesday's but not as cool as Monday's, we assume that Wednesday's Temp is in-between -6 & -2
that makes
c. -4 a reasonable choice
Answer:
C) -4 degrees
Step-by-step explanation:
Let x be the temperature on sunday,
Then, according to the question,
The temperature on monday = x - 6,
On Tuesday = (x-6) + 4 = x - 2,
Now, Wednesday's temperature was cooler than Tuesday's, but not as cool as it was on Monday,
That is, x - 6 < temperature on wednesday < x - 2
⇒ x- 6 - x < temperature on wednesday - x < x - 2 - x
⇒-6 < temperature on wednesday - temperature on sunday < -2
Since, -6 < -4 < -2
Hence, the possible difference between the temperature on Wednesday, as compared to the temperature on Sunday would be -4.

Final answer:
The professor can assign eight different tasks to her eight teaching assistants in 40,320 different ways, calculated by the factorial of eight (8!).
Explanation:
The question pertains to the number of ways to assign eight different tasks to eight teaching assistants. This problem can be solved using the concept of permutations, which is a fundamental principle in combinatorics, a branch of mathematics.
To find the number of different permutations of eight distinct items (the tasks), we would calculate 8!, which signifies factorial of eight. This represents the product of all positive integers up to 8:
8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40,320Therefore, there are 40,320 different ways the professor can make the assignments to her eight teaching assistants.
